FORWARD-LOOKING STATEMENTS

This annual report on Form 10-K contains, in addition to historical information, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on management’s current expectations and are subject to a number of factors and uncertainties, which could cause actual results to differ materially from those described in such statements. We caution investors that actual results or business conditions may differ materially from those projected or suggested in forward-looking statements as a result of various factors including, but not limited to, the following: uncertainties as to the utility and market for our potential products; uncertainties associated with pre-clinical and clinical trials of our drug delivery candidates; our limited experience in product development and expected dependence on potential licensees and collaborators for commercial manufacturing, sales, distribution and marketing of our potential products; possible development by competitors of competing products and technologies; lack of assurance regarding patent and other protection of our proprietary technology; compliance with and change of government regulation of our activities, facilities and personnel; uncertainties as to the extent of reimbursement for our potential products by government and private health insurers; our dependence on key personnel; our history of operating losses and accumulated deficit; and economic conditions related to the biotechnology and biopharmaceutical industry. We cannot assure you that we have identified all the factors that create uncertainties. Readers should not place undue reliance on forward-looking statements.

Dollar amounts are presented in thousands throughout this document.

RESTATEMENT

Subsequent to the issuance of the 2005 consolidated financial statements, we determined that the common stock purchase warrants that were issued as part of our equity finance transactions in October 2003, April 2004 and August 2004, respectively, and which were accounted for in stockholders’ equity at their relative fair value upon issuance, should have been accounted for as derivative liabilities in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The warrants did not meet any of the scope exceptions allowed by SFAS 133. Specifically, the warrants did not meet the criteria in paragraph 11(a) of SFAS 133 that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. The warrants, when classified as derivative liabilities are required to be initially recorded at fair value and to be marked to fair value at the end of each reporting period, which results in a non-cash charge or credit to other income and expense in our consolidated statement of operations.

The accompanying consolidated financial statements for the years ended December 31, 2005 and 2004 have been restated. See Note 14 to the consolidated financial statements. Additionally, selected consolidated financial data for the year ended December 31, 2003, as presented in Item 6, has been restated.

Business of Pro-Pharmaceuticals

Overview

Pro-Pharmaceuticals is a development stage pharmaceutical company engaged in the discovery, development and commercialization of carbohydrate-based therapeutic compounds for advanced treatment of cancer, liver, microbial, cardiovascular and inflammatory diseases. Our initial focus is the development of a new generation of anti-cancer treatments using carbohydrate polymers with the intent of enhancing the safety and efficacy of chemotherapy agents. Our technology utilizes carbohydrates to increase efficacy and reduce toxicity of chemotherapeutic drugs; “rescue” drugs that were shelved for toxicity or “half-life” issues; increase the solubility of existing drugs, and develop carbohydrate polymers as new chemical entities.

The need to improve drug therapies, particularly anti-cancer agents, is significant and represents a large market opportunity. Chemotherapeutics in use today typically cause serious adverse side effects that dramatically decrease a patient’s quality of life. DAVANAT®, our lead product candidate, may increase the efficacy and decrease the toxicity of current chemotherapies when used in combination with existing U.S. Food and Drug Administration (FDA)-approved cancer drugs. In combination with 5-Fluorouracil (5-FU) — one of the most widely used chemotherapeutics in the world — DAVANAT® has successfully completed a Phase I clinical trial for end-stage patients with all solid tumors and a Phase II trial for end-stage patients with metastatic colorectal cancer. We are currently dosing patients in two Phase II trials for first-line treatment of colorectal and biliary cancer. We have entered into a research collaboration with the Mount Sinai School of Medicine to evaluate the anti-fibrotic effects of one of our other novel carbohydrate compounds. All of our product candidates are in the development stage with one, DAVANAT®, in Phase II clinical trials.

Background on Carbohydrates

In order to function biologically, living organisms require the capability to recognize cellular information and trigger and perform biochemical reactions. Organisms as complex as human beings require systems with extraordinarily large capacity to recognize and translate information on a molecular level because of the tremendous number of different molecular messages that must be quickly and unambiguously deciphered, accepted or rejected. To accomplish this very important task, a class of molecules capable of great variation in shape, orientation and composition is required. Carbohydrates serve this function in the body because they have the large range of structural properties, including linkage variations, branching and anomeric isomers, that enables them to provide the significant recognition capabilities required. These complex molecules are also referred to as polysaccharides or complex sugars.

The particular role of carbohydrates, in this regard, is recognition of molecular information that triggers biological reactions. These activities include signal transmission, cell recognition, interaction and binding by other cells, hormones and viruses. Carbohydrates often accomplish this by working with lectins, which are carbohydrate binding proteins that exist on cells, and are not antibodies and have no enzymatic activity. Biological processes that involve lectin binding include a vast array of cell-cell interactions including infections, toxins and many physiological processes such as control and spread of metastasis.

In addition to their place in normal cell functioning, carbohydrates have been shown to play an important role in major diseases including cancer, cardiovascular disease, Alzheimer’s disease, inflammatory disease and viral infections.

Due to their structural complexity, which suits them for their cellular information transmission role, carbohydrates have not received as much scientific attention as nucleic acids and proteins and are not as well understood. We believe this offers a largely untapped area for treatment of disease including chemotherapeutics, infection treatment, vaccines and antibiotics. Our scientists have substantial expertise, developed over decades of study, in the area of carbohydrates that may enable us to efficiently develop successful products for disease treatment.

Drug Delivery Technologies and Importance for Cancer Treatment

The ultimate objective of enhanced drug delivery is to control and optimize localized application of the drug at the target site (location of disease) and rapidly eliminate from the body any amount not delivered to diseased tissue. Conventional drug delivery systems, such as controlled or sustained release, transdermal administration and others, are based on a physical erosion process for delivery of an active drug into the body over time with the objective of improving patient compliance with the therapy regimen. These systems do not address the need for site targeting, localized release or elimination of undelivered drug from the body — all factors related to protection of healthy tissue from adverse or toxic effects of drugs.

The need for drug target delivery is widely recognized in the area of chemotherapy because the object of this treatment — killing tumor cells — is the factor that makes the treatment so toxic for healthy cells. Given the prominence of cancer as a disease, and the limitations of chemotherapy as a form of treatment, we selected chemotherapy drugs as the initial focus for our targeted delivery technology.

The limitations of these drugs create the opportunity for our target delivery technology. First, most chemotherapies kill cancer cells by disrupting cell division or formation, and hence are particularly damaging to growth and replication of the normal cells required by the body. The effect is most noticeable in fast-growing cells such as blood cells, digestive tract tissue, hair follicles, and reproductive organ cells. As a result, patients typically experience immediate and sometimes long-term decline in quality of life due to hair loss, nausea and other digestive problems, as well as anemia, fatigue, cardiovascular damage, and colon ulceration, among others.

Also, without the ability to target diseased tissue, chemotherapy is limited as a treatment by patient tolerance levels. Chemotherapy cannot always be administered in doses high enough to have optimal efficacy for disease reduction if the side effects to healthy tissue are too severe for patient recovery.

Business Strategy of Pro-Pharmaceuticals

Our objective is to discover, develop and commercialize carbohydrate-based therapeutic compounds for advanced treatment of cancer, liver, microbial, cardiovascular and inflammatory diseases. We foresee a market demand for target delivery of chemotherapy drugs that provide increased efficacy for treating cancer patients while reducing the toxic side effects of chemotherapy. Our initial focus is DAVANAT® is a non-toxic, target delivery technology based on a proprietary carbohydrate compound that we are combining with chemotherapy drugs that have been approved by the FDA and are widely used.

With respect to DAVANAT® in particular, our business objective is to develop it initially in combination with 5-FU and other chemotherapy drugs and biologics, and subsequently for other diseases, so that as a target delivery product it has broad application. Our clinical trial data to date in late stage patients shows that DAVANAT® keeps 5-FU in the blood stream substantially longer than 5-FU without DAVANAT® with no increase in key toxicity indicators. We are currently conducting clinical trials with first line colorectal and biliary cancer patients to demonstrate increased efficacy of DAVANAT® and to further support that this occurs with no increase in key toxicity indicators We plan to collaborate with pharmaceutical companies interested in improving compounds in these areas.

Product Development

We are initially developing a pipeline of drug target delivery products that may be combined with FDA-approved and widely-used chemotherapies and biologics so as to increase their efficacy while reducing the toxic side effects. Based on our pre-clinical research, we believe DAVANAT®, when combined with approved and broadly marketed chemotherapies including irinotecan, doxorubicin, oxaliplatin, cisplatin, and bevacizumab (AVASTIN®) can significantly increase their clinical benefit.

We are developing other carbohydrate-based therapeutic compounds for treatment of other serious disease. These product candidates are all in the pre-clinical stage of development.

DAVANAT®

DAVANAT®, our lead product candidate in development, is a proprietary carbohydrate (polysaccharide) polymer comprised of mannose and galactose carbohydrates in a CARBOSOME formation. DAVANAT® is a complex polysaccharide derived from plant sources that has a precisely defined chemical structure. It is the galactomannan isolated from seeds of Cyamopsis Tetragonoloba, and subjected to a controlled partial chemical and physical degradation.

We believe the mechanism of action for DAVANAT® is based upon interaction with lectins, which are cell surface proteins that bind only to a particular kind of carbohydrate. DAVANAT® is formulated to attach to specific lectins (Galectins), which are abundant on the surface of tumor cells, while selectively avoiding healthy tissue. The galactose residue side chain attached to the carbohydrate polymer backbone targets lectin receptors that are specific and over-expressed on cancer cells. The receptor effectively interacts with the carbohydrate, chemotherapy drug combination and assists in the accumulation of the chemotherapy in the cancer cell, bypassing the normal defense mechanism. This form of targeted delivery may allow for administration of higher doses of chemotherapy thereby increasing efficacy while reducing toxicity.

Pre-clinical Studies of DAVANAT®

Our pre-clinical studies demonstrate that DAVANAT® when used in combination with 5-FU significantly reduces the toxicity of this widely-used chemotherapy. Pre-clinical studies also demonstrated delayed tumor growth and tumor shrinkage against a control group of animals when DAVANAT® was used with common combination therapies such as 5-FU/Leucovorin, 5-FU/Avastin®, and 5-FU/Irinotecan. These studies demonstrated not only that DAVANAT® enables increased efficacy of these chemotherapeutics, but also that it could be used effectively with several different chemotherapy drugs.

Clinical Trial Development of DAVANAT®

 

 

 

Phase I Trial for Third- and Fourth- Line Patients with Solid Tumors.    In March 2005 we completed a Phase l study to evaluate DAVANAT® alone and in combination with 5-FU to treat solid tumors in a trial of 40 end-stage patients with advanced solid tumors who failed chemotherapy, radiation therapy, and/or surgical treatments. The open label study was designed to evaluate the safety and tolerability of escalating doses of DAVANAT® (30-280mg/m2) when administered alone, and with a constant dose of 5-FU (500mg/m2). The third-and fourth-line cancer patients when entering the study had advanced metastatic tumors that averaged more than 100mm, had progressive disease, and were refractory to chemotherapeutic agents including 5-FU.

Based on objective tumor assessment the disease was stabilized in 14 of 26 patients with measurable disease. Furthermore, 7 of 10 patients were stabilized at the highest dose level of DAVANAT® administered in the sixth and final cohort. Efficacy results are analyzed based on Response Evaluation Criteria in Solid Tumors (RECIST) following completion of the second cycle of treatment. RECIST defines stable disease as “[n]either sufficient shrinkage to qualify for Partial Response (more than 30% shrinkage) nor sufficient increase to qualify for Progressive Disease (greater than 20% increase) taking as reference the smallest sum longest diameter since the treatment started.”

The Phase I data also indicate that DAVANAT®/5-FU was well tolerated by patients. The maximum tolerated dose was not reached indicating DAVANAT’s® safety and the potential for further dose escalation. Adverse side effects were mostly disease related. Additionally, the results showed that 5-FU, in combination with DAVANAT®, remained significantly longer in the bloodstream of cancer patients, potentially increasing 5-FU’s efficacy with no increase in toxicity.

 

   

Phase II Trial for End Stage Patients with Third- and Fourth- Line Metastatic Colorectal Cancer.    In 2004, we initiated a Phase II clinical trial to further evaluate DAVANAT®/5-FU for end-stage patients with third- and fourth-line metastatic colorectal cancer. This cancer is the fourth most commonly diagnosed cancer among men and women in the United States. The multi-center, open label, single-dose level study was designed to evaluate up to 15 patients in stage one, and up to 18 patients in stage two. The study, which was designed to evaluate the efficacy and safety of DAVANAT®/5-FU when administered at the same regimen as Phase I in monthly cycles, had two objectives: (1) to document the rate of response and stabilization of patients with advanced colon cancer; and (2) to continue evaluating the safety of the DAVANAT®/5-FU combination. Dosing of patients began in May 2005. We stopped recruiting for the study in May 2006 because we achieved our objective and saw no benefit to continue the study. We have replaced this study with two first line phase II trials to demonstrate the efficacy of DAVANAT®/5-FU in early stage patients. We closed the study in October 2006 and are currently summarizing the results. The unaudited data for the study indicate that based on objective tumor assessment one patient experienced a partial tumor response and the disease was stabilized in 6 of 20 patients. Again the study demonstrated the safety and tolerability of DAVANAT®/5-FU and showed that 5-FU, in combination with DAVANAT®, remains significantly longer in the bloodstream of cancer patients, potentially increasing 5-FU’s efficacy with no increase in toxicity.

 

   

Phase II Trial for First-lineTreatment of Patients with Biliary Cancer.    In 2005, we initiated a Phase ll trial for the first-line treatment of patients with biliary cancer. Biliary cancer may represent an opportunity for orphan drug status approval. See “FDA ‘Orphan Drug’ Designation” below under “Government Regulation.” The multi-center, open label, single-dose level study is designed to evaluate up to 42 patients. The study, will evaluate the efficacy and safety of DAVANAT®/5-FU when administered for at least two monthly cycles or until disease progression. The trial has two objectives: (1) complete/partial tumor response in 20% of patients (17% in the first stage); and (2) the safety of DAVANAT®/5-FU regimen in this patient population. We currently have three sites recruiting patients and are adding additional sites in the U.S. and Europe.

 

   

Phase II Trial for First-line Patients with Colorectal Cancer.    In November 2006, we initiated a Phase II trial for first-line treatment of colorectal cancer patients. The multi-center, open label, single-dose level study is designed to evaluate up to 50 patients who are unable to sustain the high toxicity of current intensive combination chemotherapy. The study, is expected to evaluate the efficacy and safety of DAVANAT®/5-FU when administered in combination with Leucovorin and AVASTIN® in two monthly cycles or until disease progression or toxicity. The primary objectives of the study are a complete or partial response in 33 percent of the patients and a secondary measurement of progression free survival at 6 and 12 months. We currently have six sites participating in the study and are adding additional sites.

 

   

Phase III Trial for Patients with Second-Line Colorectal Cancer.    We initiated a Phase III trial for second-line treatment of patients with colorectal cancer. The multi-center, randomized, double blind study is designed to evaluate up to 100 patients. The study which is expected to evaluate the efficacy and safety of DAVANAT®/5-FU in administered in combination with Leucovorin and Oxaliplatin or Leucovorin and Irinotecan depending on what patients have received in first line therapy, in two monthly cycles or until disease progression. The study has the following objectives: progression free survival (six months), response rates, time to progression and quality of life. We currently have four sites and recruiting patients is on hold pending obtaining the financial resources to proceed with this trial.

Patents and Proprietary Rights

Patents and other intellectual property rights are essential to our business. Our success depends in part upon our continuing ability to file and maintain U. S. and foreign patents that adequately protect the intellectual property important to the development of our business.

We have been awarded 5 patents and have an additional 13 patent applications pending in the United States. In addition we have been awarded 14 foreign patents and have 27 foreign patent applications pending in various international jurisdictions. Further, we have 1 PCT (Paris Convention Treaty) patent application. Many of our patents and patent applications cover methods and composition for reducing toxicity and enhancing the delivery of a chemotherapeutic drug by co-administering a polysaccharide with a chemotherapeutic agent. Additionally, we have patent applications in a number of other areas related to utilizing carbohydrates to treat major disease.

We have also developed trade secrets and know-how. We require our employees, consultants and collaborators to enter into confidentiality agreements to protect our intellectual property. Please see “Risks Related to Pro-Pharmaceuticals — We Are a Counterclaim Defendant in a Lawsuit Instituted by CEO David Platt” and “Risks Related to the Drug Development Industry — Our Competitive Position Depends on Protection of Our Intellectual Property” for additional discussion of risks related to protection of our intellectual property based on inventions.

We have registered the following trademarks: PRO-PHARMACEUTICALS, INC., DAVANAT, and ADVANCING DRUGS THROUGH GLYCOSCIENCE. We filed applications to register additional trademarks and servicemarks.

Research

Our initial focus is on the design and analysis of carbohydrate-based compounds for targeted drug delivery. We contract with independent laboratories and accredited facilities to conduct our research, which is designed, evaluated and managed by our scientists. We do not anticipate building in-house research or development facilities or hiring staff in this connection other than for purposes of designing and managing our out-sourced research.

As we develop products eligible for clinical trials, we contract with independent parties to design the trial protocols, arrange for and monitor the clinical trials, collect data and analyze data. In addition, certain clinical trials for our products may be conducted by government-sponsored agencies and will be dependent on governmental participation and funding. Our dependence on independent parties and clinical sites involves risks including reduced control over the timing and other aspects of our clinical trials.

Our research and development expenditures totaled approximately $13.5 million for the cumulative period from inception (July 10, 2000) through December 31, 2006.

Manufacturing and Marketing

We are a development company at this time and do not intend to establish internal facilities for the manufacture of our products for clinical or commercial production. In order to have our products manufactured, we have developed and will continue to develop relationships with third-parties that have established manufacturing capabilities for the manufacture of our products on a contract basis.

Because our products are in the development stage, we have not created a sales and marketing staff to commercialize pharmaceutical products. If we develop products eligible for commercial sale, we will need to develop a sales and marketing capability or rely on third parties such as licensees, collaborators, joint venture partners or independent distributors to market and sell those products. Our dependence on third-party manufacturers and marketers will involve risks relating to our reduced control, and other risks including those discussed in “Risk Factors Related to Pro-Pharmaceuticals Results — We Will Depend on Third Parties To Manufacture and Market Our Products.”

Competition

A limited number of biotechnology and pharmaceutical companies are developing new drug delivery technologies for the treatment of cancer and other diseases. Drug delivery targeting technologies including monoclonal antibodies being developed by companies such as Seattle Genetics, Inc., Immunogen, Inc. and Dendreon Corporation could be competitive with our carbohydrate-based platforms. Several companies, including Momenta Pharmaceuticals, Inc., and GlycoFi, Inc., are developing carbohydrate technologies and sequencing of complex sugars to improve or develop new or existing drugs. Neose Technologies, Inc. is seeking to improve the therapeutic profile of widely used protein-based drugs and Optimer Pharmaceuticals, Inc. is developing carbohydrate technologies for drug discovery and improvement. While these companies may broaden the market for our products they may also provide competitive alternatives to our products.

Please see “Risk Factors Related to the Drug Development Industry — We Face Intense Competition in the Biotechnology and Pharmaceutical Industries” for additional discussion related to our current and potential competition.

Government Regulation

The research, development, testing, manufacture, labeling, promotion, advertising, distribution, and marketing, among other things, of our products are extensively regulated by governmental authorities in the United States and other countries. In the United States, the FDA regulates drugs under the federal Food, Drug, and Cosmetic Act and its implementing regulations. Failure to comply with the applicable U.S. requirements may subject us to administrative or judicial sanctions, such as FDA refusal to approve pending new drug applications, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, and/or criminal prosecution. Please see “Risk Factors That May Affect Results — We Will Need Regulatory Approvals To Commercialize Our Products” for additional discussion of risks related to regulatory compliance.

Drug Approval Process

Drugs may not be marketed in the U.S. until the FDA has approved them. The steps required before a drug may be marketed in the U.S. include (similar rules apply in other countries):

 

  1. Pre-clinical laboratory tests, animal studies, and formulation studies,

 

  2. Submission to the FDA of an Investigational New Drug application (IND) for human clinical testing, which must become effective before human clinical trials may begin,

 

  3. Adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug for each indication,

 

  4. Submission to the FDA of a New Drug Application (NDA),

 

  5. Satisfactory completion of an FDA inspection of the manufacturing facility or facilities, at which the drug is produced to assess compliance with cGMP established by the FDA,

 

  6. FDA review and approval of the NDA, and

 

  7. FDA review and approval of a trademark used in connection with a pharmaceutical.

Pre-clinical tests include laboratory evaluation of product chemistry, toxicity, and formulation, as well as animal studies. The results of the pre-clinical tests, together with manufacturing information and analytical data, are submitted to the FDA as part of an IND, which must become effective before human clinical trials may begin. An IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions about issues such as the conduct of the trials as outlined in the IND. In such a case, the IND sponsor and the FDA must resolve any outstanding FDA concerns or questions before clinical trials can proceed. There is no certainty that submission of an IND will result in the FDA allowing clinical trials to begin.

Table of Contents

Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified investigators. Clinical trials are conducted under protocols detailing the objectives of the study, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND.

Clinical trials typically are conducted in three sequential phases, but the phases may overlap or be combined. Each trial must be reviewed and approved by an independent Institutional Review Board (IRB) before it can begin. Study subjects must sign an informed consent form before participating in a clinical trial. Phase I usually involves the initial introduction of the investigational drug into people to evaluate its safety, dosage tolerance, pharmacodynamics, and, if possible, to gain an early indication of its effectiveness. Phase II usually involves trials in a limited patient population to (i) evaluate dosage tolerance and appropriate dosage; (ii) identify possible adverse effects and safety risks; and (iii) evaluate preliminarily the efficacy of the drug for specific indications. Phase III trials usually further evaluate clinical efficacy and test further for safety by using the drug in its final form in an expanded patient population. There is no assurance that these trials will be completed within a specified period of time, if at all.

Assuming successful completion of the required clinical testing, the results of the pre-clinical studies and of the clinical studies, together with other detailed information, including information on the manufacture and composition of the drug, are submitted to the FDA in the form of an NDA requesting approval to market the product for one or more indications. Before approving an NDA, the FDA usually will inspect the facilities at which the drug is manufactured, and will not approve the product unless cGMP compliance is satisfactory. If the FDA evaluates the NDA and the manufacturing facilities as acceptable, the FDA will issue an approval letter. If the FDA evaluates the NDA submission or the manufacturing facilities as not acceptable, the FDA will outline the deficiencies in the submission and often will request additional testing or information. Even if an applicant submits the requested additional information, the FDA ultimately may decide that the NDA does not satisfy the regulatory criteria for approval. The testing and approval process requires substantial time, effort, and financial resources, and there is no assurance that any approval will be granted on a timely basis, if at all. After approval, certain changes to the approved product, such as adding new indications, manufacturing changes, or additional labeling claims are subject to further FDA review and approval.

Please see “Risks Related to the Drug Development Industry — We Will Need Regulatory Approvals to Commercialize Our Products” for additional discussion of regulatory risks related to our drug development program.

FDA “Fast Track” Program; Priority Review

The FDA’s “fast track” program is intended to facilitate the development and expedite the review of drugs intended for the treatment of serious or life-threatening diseases and that demonstrate the potential to address unmet medical needs for such conditions. Under this program, the FDA can, for example, review portions of an NDA for a fast track product before the entire application is complete, thus potentially beginning the review process at an earlier time. We may seek to have some of our products designated as fast track products, with the goal of reducing review time. There can be no guarantee that the FDA will grant any of our requests for fast track designation, that any fast track designation would affect the time of review, or that the FDA will approve the NDA submitted for any of our product candidates, whether or not fast track designation is granted. Additionally, FDA approval of a fast track product can include restrictions on the product’s use or distribution (such as permitting use only for specified medical procedures or limiting distribution to physicians or facilities with special training or experience), and can be conditioned on the performance of additional clinical studies after approval.

FDA procedures also provide priority review of NDAs submitted for drugs that, compared to currently marketed products, offer a significant improvement in the treatment, diagnosis, or prevention of a disease. NDAs that are granted priority review are acted upon more quickly than NDAs given standard review. The FDA’s goal

is to act on 90% of priority NDAs within six months of receipt. We anticipate seeking priority review with regard to some of our product candidates. There can be no guarantee that the FDA will grant priority review status in any instance, that priority review status will affect the time of review, or that the FDA will approve the NDA submitted for any of our product candidates, whether or not priority review status is granted.

Post-Approval Requirements

If FDA approval of one or more of our products is obtained, we will be required to comply with a number of post-approval requirements. For example, holders of an approved NDA are required to report certain adverse reactions to the FDA and to comply with certain requirements concerning advertising and promotional labeling for their products. Also, quality control and manufacturing procedures must continue to conform to cGMP after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with cGMP. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. In addition, discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved NDA, including withdrawal of the product from the market. Also, new government requirements may be established that could delay or prevent regulatory approval of our products under development.

FDA “Orphan Drug” Designation

The FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition, which generally is a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are publicly disclosed by the FDA. Orphan drug designation does not convey an advantage in, or shorten the duration of, the regulatory review and approval process. If a product which has an orphan drug designation subsequently receives the first FDA approval for the indication for which it has such designation, the product is entitled to orphan exclusivity, meaning that the FDA may not approve any other applications to market the same drug for the same indication, except in certain very limited circumstances, for a period of seven years. As well, orphan drugs usually receive ten years of marketing exclusivity in the European Union.

Non-United States Regulation

Before our products can be marketed outside of the United States, they are subject to regulatory approval similar to that required in the United States, although the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. No assurance can be given that even if a product is approved by a regulatory authority, satisfactory prices will be approved for such product.

Environmental Regulation

Pharmaceutical research and development involves the controlled use of hazardous materials. Biotechnology and pharmaceutical companies must comply with laws and regulations governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials, biological specimens and wastes. We do not anticipate building in-house research, development or manufacturing facilities, and, accordingly, do not expect to have to comply directly with environmental regulation. However, our contractors and others conducting research, development or manufacturing activities for us may be required to incur significant compliance costs, and this could in turn could increase our expense or delay our completion of research or manufacturing programs.

Item 1A. Risk Factors

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information before deciding to invest in our common stock. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently consider immaterial may also adversely affect our business. We have attempted to identify below the major factors that could cause differences between actual and planned or expected results, but we cannot assure you that we have identified all of those factors.

If any of the following risks actually happen, our business, financial condition and operating results could be materially adversely affected. In this case, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to Pro-Pharmaceuticals (dollar amounts in thousands)

We Are at an Early Stage of Development with Limited Operating History.    We are a development-stage company with a limited operating history, and we have not generated any revenues to date. We have no therapeutic products available for sale, and none are expected to be commercially available for several years, if at all. We may never generate revenue or become profitable, even if we are able to commercialize any products.

We Have Incurred Net Losses to Date and Depend on Outside Capital.    Our accumulated deficit as of December 31, 2006 was $25,727. We will need to continue to conduct significant research, development, testing and regulatory compliance activities that, together with projected general and administrative expenses, we expect will result in substantial operating losses for the next several years. Accordingly, we do not expect to be generating sales or other revenue and will remain dependent on outside sources of financing during that time. If we are unable to raise funds from outside sources for our continuing operations, we may be adversely affected.

 

14


Table of Contents

We may raise such capital through public or private equity financings, partnerships, debt financings, bank borrowings, or other sources. Additional funding may not be available on favorable terms or at all. If adequate funds are not otherwise available, we may need to significantly curtail operations. To obtain additional funding, we may need to enter into arrangements that require us to relinquish rights to certain technologies, products and/or potential markets. To the extent that additional capital is raised through the sale of equity, or securities convertible into equity, our equity holders may experience dilution of their proportionate ownership of the company.

Based on $5,773 of available cash and cash equivalents and certificate of deposit as of December 31, 2006, we believe that we have sufficient capital to fund our operations through at least June 2007. We must raise cash before June 2007 or we may not be able to continue operations.

Our Product Candidates Are Based on Novel Unproven Technologies.    Our product candidates are based on novel unproven technologies using proprietary carbohydrate compounds in combination with FDA approved of drugs currently used in the treatment of cancer and other diseases. Carbohydrates are difficult to synthesize, and we may not be able to synthesize carbohydrates that would be usable as delivery vehicles for the anti-cancer drugs we plan to work with.

Our Drug Candidates Are in Clinical Trials and Results Are Uncertain.    We have one product candidate in human clinical trials. Pre-clinical results in animal studies are not necessarily predictive of outcomes in human clinical trials. Clinical trials are expensive, time-consuming and may not be successful. They involve the testing of potential therapeutic agents, or effective treatments, in humans, typically in three phases, to determine the safety and efficacy of the product candidates necessary for an approved drug. Many products in human clinical trials fail to demonstrate the desired safety and efficacy characteristics. Even if our products progress successfully through initial human testing, they may fail in later stages of development. We will be dependent on others to conduct our clinical trials, including clinical research organizations and, possibly, government-sponsored agencies. These trials may not start or be completed as we forecast, or may be unsuccessful.

Our Product Candidates May Not Be Successfully Commercialized.    Even if our product candidates are successful in clinical trials, they may not be successfully commercialized. Potential products may fail to receive necessary regulatory approvals, be difficult to manufacture on a large scale, be uneconomical to produce, fail to achieve market acceptance, or be precluded from commercialization by proprietary rights of third parties.

Our Lack of Operating Experience May Cause Us Difficulty in Managing Our Growth.    We have limited experience in manufacturing or procuring products in commercial quantities, conducting other later-stage phases of the regulatory approval process, selling pharmaceutical products, or negotiating, establishing and maintaining strategic relationships. Any growth of our company will require us to expand our management and our operational and financial systems and controls. If we are unable to do so, our business and financial condition would be materially harmed. If rapid growth occurs, it may strain our operational, managerial and financial resources.

We Will Depend on Third Parties to Manufacture and Market Our Products.    We do not have, and do not now intend to develop, facilities for the manufacture of any of our products for clinical or commercial production. Accordingly, we will need to develop relationships with manufacturers and enter into collaborative arrangements with licensees or have others manufacture our products on a contract basis. We expect to depend on such collaborators to supply us with products manufactured in compliance with standards imposed by the FDA and foreign regulators.

In addition, we have limited experience in marketing, sales or distribution, and we do not intend to develop a sales and marketing infrastructure to commercialize our pharmaceutical products. If we develop commercial products, we will need to rely on licensees, collaborators, joint venture partners or independent distributors to market and sell those products.

We Depend on Key Individuals to Develop Our Products and Pursue Collaborations.    We are highly dependent on David Platt, Ph.D., President and Chief Executive Officer; Anatole Klyosov, Ph.D., our chief scientist; and Eliezer Zomer, Ph.D., Vice President, Manufacturing and Product Development. The loss of any of these persons, or failure to attract or retain other key personnel, could prevent us from pursuing collaborations or developing our products and core technologies.

We Are a Counterclaim Defendant in a Lawsuit Instituted by CEO David Platt.    Our CEO David Platt filed a lawsuit in Massachusetts in January 2004 against GlycoGenesys, Inc. for claims including breach of contract. In its answer GlycoGenesys named us as a counterclaim defendant alleging tortious interference and misappropriation of proprietary rights, and seeks monetary damages and injunctive relief related to our intellectual property. In March 2004, we answered the counterclaim and denied any liability. We and Dr. Platt intent to contest these counterclaims vigorously. In October 2006, pursuant to a U.S. Bankruptcy Court approval of a liquidation of GlycoGenesys Marlborough Research and Development, Inc. (now known as Prospect Therapeutics, Inc) purchased selected assets of GlycoGenesys including this litigation. If we do not prevail there could be a material adverse impact on our financial position, results of operations or cash flows.

Risks Related to the Drug Development Industry

We Will Need Regulatory Approvals to Commercialize Our Products.    We currently do not have products approved for sale in the U.S. or any foreign market. We are required to obtain approval from the FDA in order to sell our products in the U.S. and from foreign regulatory authorities in order to sell our products in other countries. The FDA’s review and approval process is lengthy, expensive and uncertain. Extensive pre-clinical and clinical data and supporting information must be submitted to the FDA for each indication for each product candidate in order to secure FDA approval. The FDA could reject an application or require us to conduct additional clinical or other studies as part of the regulatory review process. Delays in obtaining or failure to obtain FDA approvals would prevent or delay the commercialization of our products, which would prevent, defer or decrease our receipt of revenues. If we receive initial regulatory approval, our product candidates will be subject to extensive and rigorous ongoing domestic and foreign government regulation.

Our Competitive Position Depends on Protection of Our Intellectual Property.    Development and protection of our intellectual property are critical to our business. If we do not adequately protect our intellectual property, competitors may be able to practice our technologies. Our success depends in part on our ability to obtain patent protection for our products or processes in the United States and other countries, protect trade secrets, and prevent others from infringing on our proprietary rights.

Since patent applications in the United States are maintained in secrecy for at least portions of their pendency periods (published on U.S. patent issuance or, if earlier, 18 months from earliest filing date for most applications) and since other publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we are the first to make the inventions to be covered by our patent applications. The patent position of biopharmaceutical firms generally is highly uncertain and involves complex legal and factual questions. The U.S. Patent and Trademark Office has not established a consistent policy regarding the breadth of claims that it will allow in biotechnology patents.

We cannot assure you that all of our patent applications will issue as patents or that the claims of any issued patents will afford meaningful protection for our technologies or products. In addition, patents issued to us or our licensors may be challenged and subsequently narrowed, invalidated or circumvented. Patent litigation is widespread in the biotechnology industry and could harm our business. Litigation might be necessary to protect our patent position or to determine the scope and validity of third-party proprietary rights, and we may not have the required resources to pursue such litigation or to protect our patent rights.

Although we require our scientific and technical employees and consultants to enter into broad assignment of inventions agreements, and all of our employees, consultants and corporate partners with access to proprietary information to enter into confidentiality agreements, these agreements may not be honored.

We are a counterclaim defendant in a lawsuit instituted by Dr. Platt. See “Risks Related to Pro-Pharmaceuticals” above.

Products We Develop Could Be Subject to Infringement Claims Asserted by Others.    We cannot assure that products based on our patents or intellectual property that we license from others will not be challenged by a third party claiming infringement of its proprietary rights. If we were not able to successfully defend our patents or licensed rights, we may have to pay substantial damages, possibly including treble damages, for past infringement.

We Face Intense Competition in The Biotechnology and Pharmaceutical Industries.    The biotechnology and pharmaceutical industries are intensely competitive. We face direct competition from U.S. and foreign companies focusing on drug delivery technologies, which are rapidly evolving. Our competitors include major, multinational pharmaceutical and chemical companies, specialized biotechnology firms and universities and other research institutions. Many of these competitors have greater financial and other resources, larger research and development staffs and more effective marketing and manufacturing organizations, than we do. In addition, academic and government institutions are increasingly likely to enter into exclusive licensing agreements with commercial enterprises, including our competitors, to market commercial products based on technology developed at such institutions. Our competitors may succeed in developing or licensing technologies and products that are more effective or less costly than ours, or succeed in obtaining FDA or other regulatory approvals for product candidates before we do.

Health Care Cost Containment Initiatives and the Growth of Managed Care May Limit Our Returns.    Our ability to commercialize our products successfully will be affected by the ongoing efforts of governmental and third-party payors to contain the cost of health care. These entities are challenging prices of health care products and services, denying or limiting coverage and reimbursement amounts for new therapeutic products, and for FDA-approved products considered experimental or investigational, or which are used for disease indications without FDA marketing approval.

Even if we succeed in bringing any products to the market, they may not be considered cost-effective and third-party reimbursement might not be available or sufficient. If adequate third-party coverage is not available, we may not be able to maintain price levels sufficient to realize an appropriate return on our investment in research and product development. In addition, legislation and regulations affecting the pricing of pharmaceuticals may change in ways adverse to us before or after any of our proposed products are approved for marketing.

Our Insurance Coverage May Not Be Adequate In All Circumstances.    In the future, we may, in the ordinary course of business, be subject to claims by, and liability to, persons alleging injury as a result of taking products we have under development. If we are successful in having products approved by the FDA, the sale of such products would expose us to additional potential product liability and other claims resulting from their use. This liability may result from claims made directly by consumers or by pharmaceutical companies or others selling such products. Although we currently have insurance coverage for both product liability and professional liability, it is possible that we will not be able to maintain such insurance on acceptable terms. Any inability to maintain insurance coverage on acceptable terms could prevent or limit the commercialization of any products we develop.

Risks Related to Our Stock

Stock Prices for Biopharmaceutical and Biotechnology Companies Are Volatile.    The market price for securities of biopharmaceutical and biotechnology companies historically has been highly volatile, and the market from time-to-time has experienced significant price and volume fluctuations that are unrelated to the operating performance of such companies. Fluctuations in the trading price or liquidity of our common stock may adversely affect our ability to raise capital through future equity financings.

Table of Contents

Large Sales Could Reduce the Trading Price of our Common Stock.    Listed on the American Stock Exchange since September 2003, our common stock, despite certain increases of trading volume from time to time, experiences periods when it could be considered “thinly traded.” On March 21, 2007, we issued approximately 5.2 million shares to discharge approximately $3.9 million of $4.4 million outstanding obligations under our 7% Convertible Debentures. We issued the shares at a discount to the then trading price of our stock. Although resale of these shares will be subject to the volume limitations of Rule 144 under the Securities Act (as they are “restricted securities”), the former Debenture holders and warrant holders may attempt to resell them as rapidly as Rule 144 permits. Such sales could place downward pressure on the trading price of our stock.

We May Need to Undertake Finance Transactions with Persons Who May Not Intend to Become Long-Term Investors.    Our recent equity finance transactions were structured as a so-called PIPE (private investment in public equity). In general, these transactions attract purchasers who desire to buy securities at a discount to the trading price that may be profitably and rapidly resold into the public markets after the privately placed securities are registered. Rapid resales of stock and other factors related to these transactions often exert a downward pressure on the trading price of a stock. We may find, given our present stage of development, that we must undertake this type of finance transaction in the future.

Four Principal Stockholders Own Enough Shares to Control The Company.    Four of our principal stockholders, David Platt, James Czirr, Offer Binder and Anatole Klyosov own or control approximately 31% of the outstanding shares of our common stock, and Dr. Platt and Mr. Czirr together own approximately 25%. Some or all of these stockholders, acting in concert, may be able to substantially influence the election of the Board of Directors and other corporate actions requiring stockholder approval, such as recapitalization or other fundamental corporate action, as well as the direction and policies of our company. Such concentration of ownership also could have the effect of delaying, deterring or preventing a change in control of the company that might otherwise be beneficial to stockholders.

Changes in Laws, Regulations and Financial Accounting Standards May Affect Our Reported Results of Operations.    The Sarbanes-Oxley Act of 2002 and related regulations may result in changes in accounting standards or accepted practices within our industry and could add significant new costs to being a public company. New laws, regulations and accounting standards, as well as changes to currently accepted accounting practices, could adversely affect our reported financial results and negatively affect our stock price. Additional unanticipated expenses incurred to comply with new requirements could also negatively impact our results of operations.

 

Item 1B. Unresolved Staff Comments

None.

 

Item 2. Properties

We entered into a five-year lease that commenced on August 11, 2006 for approximately 9,400 square feet for our executive offices located at 7 Wells Avenue Newton, Massachusetts. The lease provides for annual base rental payments of $235 in the first year increasing in each subsequent lease year to $244, $253, $263 and $273 respectively. In addition to base rental payments, we are responsible for our pro-rata share of increases in the operating expenses for the building after calendar year 2006 and taxes for the building after fiscal year 2007. We have the right to extend the term of the lease for an additional five year period at the prevailing market rate at the time of exercise. In connection with this new office space lease, a commercial bank has issued a letter of credit collateralized by cash we have on deposit with the bank of approximately $59.

 

Item 3. Legal Proceedings

In January 2004, Dr. Platt, our Chairman and Chief Executive Officer, filed a lawsuit in Massachusetts Superior Court against GlycoGenesys, Inc. for various claims including breach of contract. In its filing in

Table of Contents

February 2004, GlycoGenesys asserted counterclaims against us and Dr. Platt alleging tortious interference and misappropriation of proprietary rights. The counterclaims seek monetary damages and injunctive relief related to our intellectual property. In March 2004, we and Dr. Platt answered the counterclaims and denied any liability. In June 2004, the Court allowed, without opposition, a motion of GlycoGenesys for leave to file a supplemental counterclaim against us for defamation and unfair competition. On February 2, 2006, GlycoGenesys filed a voluntary petition for protection under Chapter 11 of the U.S. Bankruptcy Code, which stayed the counterclaim litigation proceedings. On June 1, 2006, the bankruptcy court approved a motion by GlycoGenesys to convert the proceeding to Chapter 7 liquidation. On October 23, 2006, the judge issued an order allowing the liquidation sale of certain GlycoGenesys assets to Marlborough Research and Development, Inc. including the counterclaim lawsuit. Marlborough Research and Development, Inc. has changed its name to Prospect Therapeutics, Inc. and has informed us that it intends to pursue the counterclaim lawsuit against us and Dr. Platt. We believe these claims are without merit and intend to contest them vigorously. We believe that any impact on the financial statements is neither probable or reasonably estimable and therefore no amounts have been recorded as of December 31, 2006

Pursuant to Board approval, we agreed to indemnify Dr. Platt for the expenses of his defense of the counterclaims. In 2006, we incurred $11 of expenses in connection with this defense. Through December 31, 2006, we have incurred cumulative expenses of approximately $438 in connection with this defense.

On January 28, 2005, we filed a request with the U.S. Patent and Trademark Office (USPTO) for an inter partes re-examination of U.S. Patent No. 6,680,306 owned by GlycoGenesys, Inc. because we believe that the invention claimed in this patent is anticipated by other inventions (technically, “prior art”), including our U.S. Patent No. 6,645,946 for DAVANAT®. In an October 18, 2005 action, the USPTO agreed with our argument that all claims stated in the ‘306 patent are anticipated by prior art. On December 19, 2005, GlycoGenesys filed a response to the USPTO, and on January 18, 2006 we responded to the GlycoGenesys submission. The matter is now before the USPTO for a final decision. We believe that the USPTO actions to date support our belief that the invention claimed in our DAVANAT patent is prior art relative to the GlycoGenesys patent.

Holders of Common Stock

As of February 7, 2007, there were approximately 235 holders of record of our common stock. Because shares of our common stock are held by depositaries, brokers and other nominees, the number of beneficial holders of our shares is substantially larger than the number of record holders. Based on information available to us, we believe there are approximately 3,100 beneficial owners of our shares of our common stock in addition to the record holders.

Dividends

There have been no cash dividends declared on our common stock since our company was formed. Dividends are declared at the sole discretion of our Board of Directors. The terms and conditions of the Convertible Debenture agreement restricts our ability to pay dividends. Our intention is not to declare cash dividends and retain all cash for our operations.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations (in thousands, except share and per share data)

RESTATEMENT

Subsequent to the issuance of the 2005 consolidated financial statements, we determined that the common stock purchase warrants that were issued as part of our equity finance transactions in October 2003, April 2004 and August 2004, respectively, and which were accounted for in stockholders’ equity at their relative fair value upon issuance, should have been accounted for as derivative liabilities in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The warrants did not meet any of the scope exceptions allowed by SFAS 133. Specifically, the warrants did not meet the criteria in paragraph 11(a) of SFAS 133 that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. The warrants, when classified as derivative liabilities, are required to be initially recorded at fair value and to be marked to fair value at the end of each reporting period, which results in a non-cash charge or credit to other income and expense in the consolidated statement of operations.

The accompanying consolidated financial statements for the years ended December 31, 2005 and 2004 have been restated. See Note 14 to the consolidated financial statements.

The accompanying management’s discussion and analysis of financial condition and results of operations reflects the restatement described above.

RECENT EVENT

On March 21, 2007, we issued approximately 5.2 million shares of our common stock at a conversion price of $0.75 per share to discharge approximately $3.9 million of the remaining $4.4 million then outstanding obligations under our 7% Convertible Debentures that we sold in February 2006. The exercise price of the common stock warrants issued in February 2006 to the same investors was reduced to $1.00 (and the number of shares issuable on exercise proportionately increased) to take into account the dilutive effect of this transaction. If all the warrants were exercised by cash payment, we would issue approximately 5 million new shares. We also agreed that

 

   

we will not make payments on the remaining debenture obligations in shares unless the price of our common stock is at least $0.85,

 

   

for 6 months after this transaction we will not offer or sell our securities without also offering them to the former debenture holders, and

 

   

we will not offer or sell our securities before April 20, 2007 at an effective price per share of our common stock lower than $0.75.

Overview

We are a development-stage company engaged in research and development of carbohydrate based therapeutic compounds. We believe our carbohydrate-based compounds offer numerous opportunities to provide advanced disease treatments. Our initial focus is on the target delivery of chemotherapy drugs for the treatment of cancer. We believe our initial carbohydrate compound — DAVANAT® — may reduce the toxic side effects of chemotherapeutic drugs and increase their efficacy by targeting delivery directly to cancerous cells, thereby creating a preferable treatment to existing oncology regimens. For additional information, please see “Item 1. Business — Business of Pro-Pharmaceuticals.”

All of our drug candidates are currently in preclinical and clinical development. We currently have only one drug candidate — DAVANAT® — in clinical development. In general, in order to commercialize our current and

 

23


Table of Contents

future drug candidates, we are required to successfully complete preclinical studies and clinical trials and obtain regulatory approvals. Current requirements for regulatory approval include:

 

   

preclinical toxicology, pharmacology and metabolism studies, as well as in-vivo efficacy studies in relevant animal models of disease;

 

   

manufacturing of drug product for use in preclinical studies and clinical trials and ultimately for commercial supply;

 

   

submission of the results of preclinical studies and information regarding manufacturing and control and proposed clinical protocol to the U.S. Food and Drug Administration (FDA) in an investigational new drug application (IND), or similar filings with regulatory agencies outside the United States;

 

   

conduct of clinical trials designed to provide data and information regarding the safety and efficacy of the product candidate in humans; and

 

   

submission of all the results of testing to the FDA in a new drug application (NDA), or similar filings with regulatory agencies outside the United States.

Upon approval by the appropriate regulatory authorities we may commence commercial marketing and distribution of the product. This process typically takes several years to complete and requires the expenditure of substantial resources. Any delay in obtaining or failure to obtain required approvals will materially adversely affect our ability to generate revenues from commercial sales relating to our drug candidates. We may file an NDA for a drug candidate in 2007. We anticipate our source of funding for the next several years to come from either financing transactions or collaborations with other pharmaceutical companies.

We are devoting substantially all of our efforts toward product research and development, and raising capital. We have no source of revenue and have incurred significant losses to date. We have incurred net losses of $25,727 for the cumulative period from inception (July 10, 2000) through December 31, 2006. Our losses have resulted principally from costs associated with research and development expenses, including clinical trial costs, and general and administrative activities. As a result of planned expenditures for future research, discovery, development and commercialization activities, we expect to incur additional operating losses for the foreseeable future.

We have raised $35,930 in capital principally through the issuance of convertible notes, the sale of common stock through a public offering and the sale of common stock and warrants through private placements as of December 31, 2006. From inception (July 10, 2000) through December 31, 2006, we used cash of $28,240 for our operations. At December 31, 2006, we had $5,773 of cash and cash equivalents and certificate of deposit available to fund future operations, which we believe is sufficient to fund our operations through at least June 2007.

Because we lack revenue and must continue our research and development, we must continually identify new sources of capital and complete financing transactions in order to continue our business. We must continually monitor the monthly “burn rate” of our capital resources.

Critical Accounting Policies and Estimates

Our significant accounting policies are more fully described in Note 2 to our Consolidated Financial Statements included in this Annual Report on Form 10-K. Certain of our accounting policies, however, are critical to the portrayal of our financial position and results of operations and require the application of significant judgment by our management, which subjects them to an inherent degree of uncertainty. In applying our accounting policies, our management uses its best judgment to determine the appropriate assumptions to be used in the determination of certain estimates. Those estimates are based on our historical experience, terms of existing contracts, our observance of trends in the industry, information available from other outside sources, and on various other factors that we believe to be appropriate under the circumstances. We believe that the critical

 

24


Table of Contents

accounting policies discussed below involve more complex management judgment due to the sensitivity of the methods, assumptions and estimates necessary in determining the related asset, liability, revenue and expense amounts.

Accrued Expenses.    As part of the process of preparing our consolidated financial statements, we are required to estimate accrued expenses. This process involves identifying services that third parties have performed on our behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in our financial statements. Examples of estimated accrued expenses include contract service fees in conjunction with pre-clinical and clinical trials, professional service fees, such as those arising from the services of attorneys and accountants and accrued payroll expenses. In connection with these service fees, our estimates are most affected by our understanding of the status and timing of services provided relative to the actual services incurred by the service providers. In the event that we do not identify certain costs that have been incurred or we under- or over-estimate the level of services or costs of such services, our reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to our judgment. We make these judgments based upon the facts and circumstances known to us in accordance with accounting principles generally accepted in the United States.

Convertible Debt Instrument.    Our convertible debt instrument issued in 2006 (the “Debentures”) constitutes a hybrid instrument that has the characteristics of a debt host contract containing several embedded derivative features that would require bifurcation and separate accounting as a derivative instrument pursuant to the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”). As permitted by SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments — an amendment of FASB Statements No. 133 and 140”, we irrevocably elected to initially and subsequently measure the Debentures in their entirety at fair value with changes in fair value recorded as either a gain or loss in the consolidated statement of operations under the caption “Change in fair value of convertible debt instrument.” Fair value of the Debentures is determined using a binomial financial valuation model that requires assumptions that are subject to significant management judgment such as volatility of our common share price, interest rates and our intention to redeem the Debentures in cash or common shares. Volatility and interest rate expectations are based on the remaining 1 year to maturity of the Debentures.

Warrants.    We have issued common stock warrants in connection with the execution of certain equity and debt financings and consulting agreements. Certain warrants are accounted for as derivative liabilities at fair value in accordance with SFAS 133. Such warrants do not meet the criteria in paragraph 11(a) of SFAS 133 that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. Changes in fair value of derivative liabilities are recorded in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities.” Warrants that are not considered derivative liabilities as defined in SFAS 133 are accounted for at fair value at the date of issuance in additional paid-in capital. The fair value of warrants without probability conditions is determined using the Black-Scholes option-pricing model using assumptions regarding volatility of our common share price, expected life of the warrant, and risk-free interest rates at each period end.

Income Taxes.    We determine if our deferred tax assets and liabilities are realizable on an ongoing basis by assessing our valuation allowance and by adjusting the amount of such allowance, as necessary. At this time our primary deferred tax asset relates to our net operating loss carryforwards. In the determination of the valuation allowance, we have considered future taxable income and the feasibility of tax planning initiatives. Should we determine that it is more likely than not that we will realize certain of our deferred tax assets for which we previously provided a valuation allowance, an adjustment would be required to reduce the existing valuation allowance. In addition, we operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues, which may require an extended period of time for resolution. Although we believe that adequate consideration has been made for such issues, there is the

 

25


Table of Contents

possibility that the ultimate resolution of such issues could have an adverse effect on the results of our operations.

Stock-Based Compensation.    Through December 31, 2005, we accounted for stock-based compensation to employees and non-employee directors under the intrinsic value method in accordance with Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” (APB No. 25) and the related interpretations. Under APB No. 25, no compensation expense is recognized for stock options granted to employees at fair market value and with fixed terms. On January 1, 2006, we adopted SFAS 123(R), “Accounting for Share Based Payment,” (SFAS 123(R)) using the modified prospective method, which results in the provisions of SFAS 123(R) being applied to the consolidated financial statements on a going-forward basis. Prior periods have not been restated. SFAS 123(R) requires companies to recognize stock-based compensation awards granted to its employees as compensation expense on a fair value method. Under the fair value recognition provisions of SFAS 123(R), stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the service period, which generally represents the vesting period. The grant date fair value of stock options is calculated using the Black-Scholes option-pricing model. The expense recognized over the service period is required to include an estimate of the awards that will be forfeited. Previously, we recorded the impact of forfeitures as they occurred. We do not anticipate any awards will be forfeited in our calculation of compensation expense due to the limited number of employees that receive stock option grants and our historical employee turnover.

We consider equity compensation to be an important component in attracting and retaining key employees. During 2006, 2005 and 2004, we awarded approximately 399,000, 272,000 and 277,750 stock options, respectively, to employees, consultants and non-employee members of our Board of Directors for normal services and we recorded $416 of related stock option expense in 2006. Because the exercise price of the options granted equal the fair market value of a share of our common stock on the date of grant and the options have fixed terms, we recorded no stock compensation expense on these awards in 2005 and 2004. If we had used the fair value method provided for under SFAS No. 123, “Accounting for Stock-Based Compensation,” our net loss in 2005 and 2004 respectively of $6,855 and $3,770 would have increased by $287 and $749 to $7,142 and $4,519 respectively.

Results of Operations

Fiscal Year Ended December 31, 2006 Compared to Fiscal Year Ended December 31, 2005 (in thousands)

Research and Development Expenses.    Research and development expenses were $3,019 during the year ended December 31, 2006 as compared to $3,040 incurred during the year ended December 31, 2005. We generally categorize research and development expenses as either direct external expense, comprised of amounts paid to third party vendors for services, or all other expenses, comprised of employee payroll and general overhead allocable to research and development. We subdivide external expenses between clinical programs and preclinical activities. We consider a clinical program to have begun upon acceptance by the FDA, or similar agency outside of the United States, to commence a clinical trial in humans, at which time we begin tracking expenditures by the product candidate. We have one product candidate — DAVANAT® — in clinical trials at this time. Clinical program expenses comprise payments to vendors related to preparation for, and conduct of, all phases of the clinical trial, including costs for drug manufacture, patient dosing and monitoring, data collection and management, oversight of the trials and reports of results. Pre-clinical expenses comprise all research and development amounts incurred before human trials begin, including payments to vendors for services related to product experiments and discovery, toxicology, pharmacology, metabolism and efficacy studies, as well as manufacturing process development for a drug candidate.

Table of Contents

Our research and development expenses for the twelve months ended December 31, 2006 as compared to the twelve months ended December 31, 2005 were as follows:

 

     Year Ended
December 31,
       2006        2005  

Direct external expenses

     

Clinical programs

   $ 1,504    $ 1,557

All other research and development expenses

     926      524
             
   $ 3,019    $ 3,040
             

Clinical trial expense decreased by $53 as the Phase I late stage cancer patient trial was completed and the Phase II late stage colorectal cancer patient trial completed dosing resulting in reduced spending that was offset by the initiation of the line I biliary duct cancer, the line I colorectal cancer and line II colorectal cancer trials. Pre-clinical spending decreased due principally to reduced DAVANAT® manufacturing costs. All other research and development costs increased due to the addition of our Chief Scientist, additional personnel to support our clinical trials and expensing stock based compensation largely related to the fair value method as required by SFAS 123(R). In summary, research and development expense in 2006 shifted from pre-clinical activities to clinical programs. The increase in clinical trial expense was due to the start-up and costs associated with the Phase II trial. We completed dosing patients in a Phase I clinical trial of DAVANAT® in March of 2005 and began dosing patients in a Phase II clinical trial of DAVANAT® in May of 2005 while the pre-clinical tests and experiments associated with DAVANAT® diminished in 2006 as compared to 2005.

We expect our research and development expenses will increase moderately in 2007 due to the new line I Phase II clinical trials and a modest increase in overhead expenses.

Both the time required and costs we may incur in order to commercialize a drug candidate that would result in material net cash inflow are subject to numerous variables, and hence we are unable at this stage of our development to forecast useful estimates. Variables that make estimates difficult include the number of clinical trials we may undertake, the number of patients needed to participate in the clinical trial, patient recruitment uncertainties, trial results as to the safety and efficacy of our product, and uncertainties as to the regulatory agency response to our trial data prior to receipt of marketing approval. Moreover, the FDA or other regulatory agencies may suspend clinical trials if we or an agency believes patients in the trial are subject to unacceptable risks, or find deficiencies in the conduct of the clinical trial. Delays or rejections may also occur if governmental regulation or policy changes during our clinical trials or in the course of review of our clinical data. Please see “Risks Related to Pro-Pharmaceuticals” and “Risks Related to the Drug Development Industry” for additional risks and other factors that make estimates difficult at this time. Due to these uncertainties, accurate and meaningful estimates of the ultimate cost to bring a product to market, the timing of costs and completion of our program and the period during which material net cash inflows will commence are unavailable at this time.

General and Administrative Expenses.    General and administrative expenses were $4,029 in 2006 or an increase of 12%, as compared to $3,615 in 2005. General and administrative expenses consist primarily of salaries, including stock based compensation, legal and accounting fees, insurance, investor relations, business development and other office related costs. Of the $414 increase in expense in 2006, approximately $385 consisted of an increase in accounting and other costs associated primarily with the convertible debentures. Approximately $273 of the increase was due to expensing stock based compensation related to the fair value method as required by SFAS 123(R). These increases were offset by a reduction in legal expense of approximately $261. Legal expenses decreased due to lower expenses associated with the intellectual property litigation with GlycoGenesys. Payroll expense increased due to the addition of our Chief Scientist and other personnel which was more than offset by lower incentive compensation payments.

 

27


Table of Contents

We expect general and administrative expenses in 2007 to be approximately the same as 2006.

Other Income and Expense.    Other income and expense was income of $3,855 in 2006 as compared to expense of $200 in 2005. Of the $4,055 increase, $8,129 is related to fair value accounting for warrant liabilities. This was offset by $4,244 of charges related to our convertible debt instrument of which $2,394 is related to fair value accounting and $1,850 is interest expense. The $1,850 of interest includes $1,358 of debt discount amortization and $492 of interest expense. Additionally, interest income in 2006 was approximately $281 or an increase of $170 as compared to $111 in 2005. Interest income consists primarily of interest income on interest-bearing cash equivalents and the certificate of deposit. The increase in interest income is due primarily to higher average interest rates and to a lesser degree due to higher average cash balances. Average interest rates were approximately 3.2% per annum in 2006 versus approximately 1.4% per annum in 2005.

Fiscal Year Ended December 31, 2005 Compared to Fiscal Year Ended December 31, 2004 (in thousands)

Research and Development Expenses.    Research and development expenses were $3,040 during the year ended December 31, 2005 as compared to $3,042 incurred during the year ended December 31, 2004.

Our research and development expenses for the twelve months ended December 31, 2005 as compared to the twelve months ended December 31, 2004 were as follows:

 

     Year Ended

All other research and development expenses

     524      485
             
   $ 3,040    $ 3,042
             

In summary, research and development expense in 2005 shifted from pre-clinical activities to clinical programs. The increase in clinical trial expense was due to the start-up and costs associated with the Phase II trial. We completed dosing patients in a Phase I clinical trial of DAVANAT® in March of 2005 and began dosing patients in a Phase II clinical trial of DAVANAT® in May of 2005 while the pre-clinical tests and experiments associated with DAVANAT® diminished in 2005 as compared to 2004.

General and Administrative Expenses.    General and administrative expenses were $3,615 in 2005 or a decrease of 15%, as compared to $4,262 in 2004. General and administrative expenses consist primarily of salaries, including stock based compensation, legal and accounting fees, insurance, investor relations, business development and other office related costs. The $647 reduction in expense in 2005, consisted of a reduction in legal expense of approximately $700. This was offset by an increase in payroll of approximately $135 and a decrease in all other spending of approximately $82. Of the $700 decrease in legal expenses approximately $560 was due to the patent arbitration between Dr. Platt, our CEO and GlycoGenesys which was conducted and completed in 2004. The arbitration concerned the rights to control prosecution of patent applications that Dr. Platt licensed to GlycoGenesys. In November 2004, the arbitrator awarded the patent prosecution rights to Dr. Platt. The remainder of the decrease in legal expenses as compared to 2004 was related to expenses incurred in 2004 to defend a lawsuit asserted by a former employee. This matter was concluded in 2004. These expense decreases were offset in part by an increase of approximately $190 associated with legal expenses to defend the counterclaim lawsuit filed by GlycoGenesys against us and Dr. Platt as described in “Item 3 — Legal Proceedings” above.

Interest and Other Income.    Other income and expense in 2005 was an expense of $200 as compared to income of $3,534 in 2004. Of the $3,734 decrease, $3,721 was related to fair value accounting associated with

warrant liabilities. Additionally interest income decreased by $13. Interest income consists primarily of interest income on interest-bearing cash equivalents. The decrease in interest income is due to lower average cash balances partially offset by higher average interest rates. Average interest rates were approximately 1.4% per annum in 2005 versus approximately 1.3% per annum in 2004.

Liquidity and Capital Resources (in thousands)

As described in the section entitled “Overview” above and elsewhere in this Annual Report on Form 10-K, we are in the development stage and have not generated any revenues to date. Since our inception on July 10, 2000, we have financed our operations primarily through private placements of convertible debt, shares of common stock and warrants, and a public offering of shares of common stock. At December 31, 2006, we had raised a total of $35,930 from these offerings and had $5,773 of cash and certificate of deposit available. On February 14, 2006 we raised $10.0 million resulting in net proceeds after transaction costs of approximately $9.3 million by issuing 7% Convertible Debentures and common stock warrants through a private placement. The 7% Convertible Debentures and related interest may be repaid in common stock subject to certain provisions. The details of this transaction are more fully described in Note 6 to our audited consolidated financial statements.

Net cash used in operations was $6,757 in 2006 and $6,127 in 2005. The increased use of cash in operations in 2006 as compared to 2005 was primarily due to increased working capital needs. We expect our cash needs in 2007 to remain at approximately the same level as 2006.

Net cash used in investing activities was approximately $5,236 in 2006 as compared to approximately $111 in 2005. The increase in 2006 as compared to 2005 was due to increased capital expenditures associated primarily with the move of our corporate offices to new leased space and a $5,000 investment in a certificate of deposit.

Net cash provided by financing activities was $8,300 in 2006, and $0 in 2005. Net cash provided by financing activities in 2006 resulted from the sale of the 7% Convertible Debentures and common stock warrants. In 2006, we elected to make two payments, amounting to $1,000 of principal in cash.

On March 21, 2007 we discharged approximately $3.9 million of our $4.4 million of obligations then outstanding under the Convertible Debentures. See “Recent Event” above in this Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

We believe that our cash on hand and certificate of deposit of $5,773 at December 31, 2006 will be sufficient to enable us to meet our financing and operating obligations through at least June 2007. We will require more cash to fund our operations and believe that we will be able to obtain additional financing. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be obtainable on terms favorable to us.

Payments Due Under Contractual Obligations (in thousands)

The following table summarizes the payments due under our contractual obligations at December 31, 2006, and the effect such obligations are expected to have on liquidity and cash flow in future periods:

Long-term debt consists of scheduled principal and interest payments on our 7% Convertible Debentures. Remaining principal of $4,925 is payable in monthly installments through January 1, 2008 ( November 30, 2007 if repaid in shares). Interest accrues at the rate of 7% and is payable monthly. Remaining interest due is $171 and is all due in less than one year. Principal and interest may be paid, at our option, in cash or shares of our common stock. Because investors may convert principal into common stock, at any time, at their option, the timing of principal and interest payments may accelerate relative to this schedule.

On March 21, 2007 we discharged approximately $3.9 million of the $4.4 million then outstanding under our Convertible Debentures. See “Recent Events,” above under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

On May 1, 2006 we entered into an operating lease for office space. The lease commenced on August 11, 2006 and extends for five years and terminates on September 30, 2011. The lease provides for annual base rental payments of $235 in the first year increasing in each subsequent lease year to $244, $253, $263 and $273 respectively. In addition to base rental payments included in the contractual obligations table above, we are responsible for our pro-rata share of increases in the operating expenses for the building after calendar year 2006 and taxes for the building after fiscal year 2007. We have the option to extend the term of the lease for an additional five year period at the prevailing market rate at the time of exercise. In connection with this new office space lease, a commercial bank has issued a letter of credit collateralized by cash we have on deposit with the bank of approximately $59. Additionally, we have a non-cancellable lease for a car which expires in October of 2007.

We have engaged outside vendors for certain services associated with our clinical trials. These services are generally available from several providers and, accordingly, our arrangements are typically cancellable on 30 days notice.

Off-Balance Sheet Arrangements

We have not created, and are not a party to, any special-purpose or off-balance sheet entities for the purpose of raising capital, incurring debt or operating parts of our business that are not consolidated into our financial statements. We do not have any arrangements or relationships with entities that are not consolidated into our financial statements that are reasonably likely to materially affect our liquidity or the availability of capital resources.

 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of loss that may impact our financial position, operating results or cash flows due to changes in the U.S. interest rates. The primary objective of our investment activities is to preserve cash until it is required to fund operations. To minimize risk, we maintain our portfolio of cash and cash equivalents in operating bank accounts and money market funds. Since our investments are short-term in duration, we believe that we are not subject to any material market risk exposure. As of December 31, 2006 we had $4,925 of principal outstanding on the convertible debentures with an interest rate fixed at 7%. We account for the convertible debentures at fair value, and changes in our share price and market interest rates will affect our earnings but will not affect our cash flows.

Item 9A. Controls and Procedures

As of the end of the period covered by this Annual Report on Form 10-K, we carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(e) and 15d-15(e). As a result of the material weakness discussed below, our management has concluded, based on their evaluation, that as of the end of the period covered by this report, our disclosure controls and procedures were not effective. Notwithstanding the material weaknesses discussed below, our Chief Executive Officer and Chief Financial Officer have concluded that the financial statements included in this Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with generally accepted accounting principles.

Our Chief Executive Officer and Chief Financial Officer, in conjunction with management, have determined that as of December 31, 2006 that we have a material weakness relating to the controls over accounting for warrants. Specifically, our procedures did not operate effectively to detect certain errors in classification of warrant liabilities in the 2003, 2004 and 2005 consolidated financial statements. As discussed in Note 14 to the consolidated financial statements, we are restating previously issued financial statements for these errors.

Remediation Status

To remedy the material weakness described above, we engaged additional resources to review any similar transactions. These changes either have been, or are in the process of being, implemented.

To remediate the material weakness disclosed in our Quarterly Report on Form 10-Q for the period ended September 30, 2006, in the fourth quarter of 2006 additional controls and procedures were implemented to ensure that the convertible debentures are accurately presented in the financial statements. These procedures include tracing journal entry support to source data and retesting fair value calculations used for recording adjustments to the convertible debenture balances. These procedures are performed by a person not involved with the original journal entry preparation.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Pro-Pharmaceuticals, Inc.

Newton, Massachusetts

We have audited the accompanying consolidated balance sheets of Pro-Pharmaceuticals, Inc. and subsidiary (a development stage company) (the “Company”) as of December 31, 2006 and 2005, and the related consolidated statements of operations, stockholders’ (deficit) equity, and cash flows for each of the three years in the period ended December 31, 2006, and for the period from inception (July 10, 2000) to December 31, 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2006 and 2005, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2006, and for the period from inception (July 10, 2000) to December 31, 2006 in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 2 to the consolidated financial statements, the Company adopted Statement of Financial Accounting Standards (“SFAS”) No. 123(R), “Share-Based Payment” on January 1, 2006 based on the modified prospective application transition method.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company’s recurring losses from operations and stockholders’ deficit raise substantial doubt about its ability to continue as a going concern. Management’s plans concerning these matters are also discussed in Note 1 to the consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

As discussed in Note 14, the accompanying 2005 and 2004 consolidated financial statements have been restated.

(A DEVELOPMENT-STAGE COMPANY)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (dollar amounts in thousands)


 

1. NATURE OF BUSINESS AND BASIS OF PRESENTATION

Pro-Pharmaceuticals, Inc. (the “Company”) is a development stage life sciences company established in July 2000. The Company is developing technologies that are intended to reduce toxicity and improve the efficacy of chemotherapy drugs by combining the drugs with proprietary carbohydrate compounds. The carbohydrate-based drug delivery compounds may also have application for drugs to treat other diseases and chronic health conditions.

The Company is devoting substantially all of its efforts toward product research and development, and raising capital. Its first product candidate began a Phase I clinical trial in end stage patients in February 2003. Patient dosing in this trial was completed in March 2005. This same product candidate began a concurrent Phase II clinical trial in end stage patients in January 2004. Patient dosing in this trial commenced in May of 2005 and was completed in May 2006. The Company has initiated two additional Phase II trials in early stage patients to test the safety and efficacy of the product.

The Company incurred net losses of $25,727 for the cumulative period from inception (July 10, 2000) through December 31, 2006. The Company expects to incur additional losses and use additional cash in its operations in the near future. Through December 31, 2006, the Company had raised $35,930 in capital through (i) the issuance of convertible notes; (ii) the sale of common stock through a public offering; and (iii) the sale of common stock and warrants through private placements. From inception (July 10, 2000) through December 31, 2006, the Company used cash of $28,240 in its operations. At December 31, 2006, the Company had $5,773 of cash and cash equivalents and certificate of deposit available to fund future operations, which management believes is sufficient cash to fund its operations through at least June 2007. The Company is actively pursuing additional sources of financing and other strategic alternatives.

The Company is subject to a number of risks similar to those of other development-stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of capital, risks associated with clinical trials of products, dependence on third-party collaborators for research operations, need for regulatory approval of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. Successful completion of the Company’s development program and, ultimately, the attainment of profitable operations is dependent upon future events, including obtaining adequate financing to fulfill its development activities and achieving a level of revenues adequate to support the Company’s cost structure. There are no assurances that the Company will be able to obtain additional financing on favorable terms, or at all, or successfully market its products.

 

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated financial statements reflect the application of certain accounting policies, as described in this note and elsewhere in the accompanying notes to financial statements.

Basis of Consolidation – The consolidated financial statements include the accounts of the Company and Pro-Pharmaceuticals Securities Corp., its wholly owned subsidiary, which was incorporated in Delaware on December 23, 2003. Pro-Pharmaceuticals Securities Corp. holds the cash and cash equivalents that are not required to fund current operating needs. All intercompany transactions have been eliminated.

Use of Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and disclosure of contingent assets

 

F-7


Table of Contents

and liabilities. Management’s estimates are based primarily on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Cash and Cash Equivalents – The Company considers all highly liquid investments with original maturities of 90 days or less at the time of acquisition to be cash equivalents.

Property and Equipment – Property and equipment, including leasehold improvements, are stated at cost, net of accumulated depreciation, and are depreciated using the straight-line method over the lesser of the estimated useful lives of the assets or the related lease term.

The estimated useful lives of property and equipment are as follows:

 

Asset Classification

  

Estimated Useful Life

Computers and office equipment

   Three years

Furniture and fixtures

   Five years

Leasehold improvements

   Life of lease

Intangible Assets – Intangible assets include patent costs, consisting primarily of related legal fees, which are capitalized as incurred and amortized over an estimated useful life of five years from issuance. Amortization expense in 2006, 2005 and 2004 was $21, $17 and $17 respectively and accumulated amortization at December 31, 2006 and 2005 totaled $70 and $50, respectively.

Prepaid and Other Current Assets – Deposits and other assets consist principally of lease deposits on the Company’s leased executive office space.

Long-Lived Assets – In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” the Company reviews all long-lived assets for impairment whenever events or circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of assets to be held or used is measured by comparison of the carrying value of the asset to the future undiscounted net cash flows expected to be generated by the asset. If such asset is considered to be impaired, the impairment recognized is measured by the amount by which the carrying value of the asset exceeds the discounted future cash flows expected to be generated by the asset.

The Company wrote off capitalized patent costs of $11, $20, and $9 in 2006, 2005, and 2004, respectively, when it was determined that the underlying intellectual property would have no future benefit to the Company.

Convertible Debt Instrument – The Company’s convertible debt instrument issued in 2006 (the “Debentures”) constitutes a hybrid instrument that has the characteristics of a debt host contract containing several embedded derivative features that would require bifurcation and separate accounting as a derivative instrument pursuant to the provisions of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”). As permitted by SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments — an amendment of FASB Statements No. 133 and 140,” the Company irrevocably elected to initially and subsequently measure the Debentures in their entirety at fair value with changes in fair value recorded as either a gain or loss in the consolidated statement of operations under the caption “Change in fair value of convertible debt instrument.” Fair value of the Debentures is determined using a financial valuation model that requires assumptions that subject to significant management judgment.

Warrants – The Company has issued common stock warrants in connection with the execution of certain equity and debt financings and consulting agreements. Certain warrants are accounted for as derivative liabilities at fair value in accordance with SFAS 133. Such warrants do not meet the criteria in paragraph

 

F-8


Table of Contents

11(a) of SFAS 133 that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. Changes in fair value of derivative liabilities are recorded in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities.” Warrants that are not considered derivative liabilities as defined in SFAS 133 are accounted for at fair value at the date of issuance in additional paid-in capital. The fair value of warrants without probability conditions is determined using the Black-Scholes option-pricing model.

Research and Development Expenses – Costs associated with research and development are expensed as incurred. Research and development expenses include, among other costs, salaries and other personnel-related costs, and costs incurred by outside laboratories and other accredited facilities in connection with clinical trials and preclinical studies.

Income Taxes – The Company accounts for income taxes in accordance with SFAS No. 109, “Accounting for Income Taxes.” This statement requires an asset and liability approach to accounting for income taxes based upon the future expected values of the related assets and liabilities. Deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and for tax loss and credit carryforwards, and are measured using the expected tax rates estimated to be in effect when such basis differences reverse. Valuation allowances are established, if necessary, to reduce the deferred tax asset to the amount that will, more likely than not, be realized.

Comprehensive Income (Loss) – Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company does not have any items of comprehensive income (loss) other than net losses as reported.

Fair Value of Financial Instruments – SFAS No. 107, “Disclosures About Fair Value of Financial Instruments,” requires disclosure of the fair value of certain financial instruments. The Company’s financial instruments consist of cash equivalents, accounts payable and accrued expenses. The estimated fair value of these financial instruments approximates their carrying value due to their short-term nature. Additionally, certain common stock warrants and the Convertible Debentures are recorded as liabilities at fair value as discussed in Note 6.

Concentration of Credit Risk – Financial instruments that subject the Company to credit risk consist of cash and cash equivalents and certificates of deposit. The Company maintains cash and cash equivalents and certificates of deposit with well-capitalized financial institutions. The Company has no significant concentrations of credit risk.

Segment Information – SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information,” requires companies to report selected information about operating segments, as well as enterprise-wide disclosures about products, services, geographic areas and major customers. Operating segments are determined based on the way management organizes its business for making operating decisions and assessing performance. The Company has concluded that it operates in one operating segment.

Stock-Based Compensation – Through December 31, 2005, the Company accounted for stock-based compensation to employees and non-employee directors under the intrinsic value method in accordance with Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” (APB No. 25) and the related interpretations. Under APB No. 25, no compensation expense is recognized for stock options granted at fair market value and with fixed terms. On January 1, 2006, the Company adopted SFAS 123(R), “Share-Based Payment,” (SFAS 123(R)) using the modified prospective method, which results in the provisions of SFAS 123(R) being applied to the consolidated financial statements on a going-forward basis. Prior periods have not been restated. SFAS 123(R) requires companies to recognize stock-based compensation awards as compensation expense on a fair value method. Under the fair value recognition provisions of SFAS 123(R), stock-based compensation cost is measured at the grant date based on the fair

value of the award and is recognized as expense over the service period, which generally represents the vesting period. The Company uses the Black-Scholes option-pricing model to calculate the grant date fair value of stock options. The expense recognized over the service period is required to include an estimate of the awards that will be forfeited. Previously, the Company recorded the impact of forfeitures as they occurred. FASB Staff Position (“FSP”) No. 123(R)-3, Transition Election Related to Accounting for the Tax Effects of Share-Based Payment Awardsrequired an entity to follow either the transition guidance for the additional-paid-in-capital pool as prescribed in SFAS No. 123(R) or the alternative transition method described in FSP No. 123(R)-3. An entity that adopted SFAS No. 123(R) using the modified prospective application method may make a one-time election to adopt the transition method described in the FSP No. 123(R)-3, and may take up to one year from the latter of its initial adoption of SFAS No. 123(R) or the effective date of the FSP No. 123(R)-3 to evaluate the available transition alternatives and make its one-time election. The Company adopted the alternative transition method provided in the FSP No. 123(R)-3 for calculating the tax effects of stock-based compensation under SFAS No. 123(R). Stock-based compensation is more fully described in Note 8.

Impact of New Accounting Standards – In June 2006, the Financial Accounting Standards Board issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (the “Interpretation”). This Interpretation clarifies the accounting for uncertainty in income taxes recognized in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” This Interpretation prescribes a more-likely-than not recognition threshold that a tax position will be sustained upon examination and a measurement attribute for the financial statement recognition of a tax position taken or expected to be taken in a tax return. This Interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. This Interpretation is effective for fiscal years beginning after December 15, 2006. The cumulative effect of applying the provisions of this Interpretation shall be reported as an adjustment to the opening balance of retained earnings in 2007. Management does not anticipate the adoption of FIN 48 will have a material impact on the consolidated financial statements.

In September 2006, the U.S. Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”). SAB 108 provides guidance on how prior year misstatements should be taken into consideration when quantifying misstatements in current year financial statements for purposes of determining whether the current year’s financial statements are materially misstated. The Company was required to adopt SAB 108 in the fourth quarter of fiscal year 2006. The adoption of SAB 108 did not have a material impact on the Company’s consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS No. 157”). SFAS 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would be separately disclosed by level within the fair value hierarchy. The Company will be required to adopt SFAS No. 157 in the first quarter of fiscal year 2008. Management is currently evaluating the requirements of SFAS No. 157 and has not yet determined the impact, if any, on the Company’s consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS No. 159”). SFAS No. 159 provides entities with an option to report selected financial assets and liabilities at fair value, with the objective to reduce both the complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. The Company will be required to adopt SFAS No. 159 in the first quarter of fiscal year 2008. The Company is currently evaluating the requirements of SFAS No. 159 and has not yet determined the impact, if any, of its adoption on its consolidated financial statements.

5. RELATED PARTY TRANSACTIONS

The Company has entered into various consulting agreements, each terminable on thirty days notice, with certain related parties as follows: (i) a corporation controlled by a person who is a stockholder, and former director and officer, of the Company for financing and business development services (subsequently terminated when such person became an employee of the Company in 2002), (ii) a corporation controlled by a person who is a stockholder, and former officer, of the Company for research and development services, including reimbursable expenses, (iii) an individual who is a stockholder of the Company for management and consultant services, and (iv) a corporation controlled by a person who is a stockholder and director of the Company for scientific advisory services. There were no related party expenses in 2006. The total related party consulting expenses and related expenses paid to these corporations and individuals were $153 and $178, for 2005 and 2004 respectively.

In addition in 2002, the stockholder and director of the Company described under (iv) above agreed to receive compensation for certain 2002 scientific advisory services in the form of 25,354 shares of common stock and 25,354 options at an exercise price of $2.96 to purchase common stock of the Company. As of December 31, 2002, the Company recorded the deemed fair value of such compensation of approximately $122 as an accrued liability. The common stock was valued at $76, based on the closing price of the publicly traded shares of common stock on the date of grant. The options were valued at $46 using the Black-Scholes option-pricing model, based on a deemed fair value of the Company’s common stock of $3.00 per share. The accrued liability at December 31, 2002 was converted to equity in 2003 when the 25,354 shares of common stock and 25,354 options were issued to this individual.

 

6. CONVERTIBLE DEBT AND WARRANT LIABILITIES

The Company has raised capital through a number of debt and equity financing transactions. The following provides a chronological description of the Company’s debt financings and certain warrants issued in connection with debt and equity financings.

2000 and 2001 Convertible Notes – During 2001 and 2000, the Company issued $1,036 and $285 of convertible notes, respectively. In August 2001, the Company offered warrants to holders of its outstanding convertible notes as an inducement to convert the notes prior to the maturity. Holders representing $1,126 of

the outstanding principal and accrued interest chose to convert at a conversion price of $2.00 per share and received 598,229 common shares and 562,801 warrants. The unexercised warrants expired in 2005. As described in Note 7, the Company valued the warrants at $503 using the Black-Scholes option-pricing model, and recorded such value as a debt conversion in 2001.

In May 2002, the Company extended the maturity date on the $195 of convertible notes payable at December 31, 2001. In consideration for the extension, the holders received one-quarter of one share of the Company’s common stock for each whole dollar amount of principal outstanding, or 48,750 shares of common stock. The Company deferred $171 in costs associated with the extension, based on the fair value of the Company’s common stock of $3.50 at the time of the extension. These deferred convertible notes payable costs were amortized ratably over the twelve-month extended term of the notes, or until conversion.

In June 2002, $80 in convertible notes payable and $10 in related accrued interest was converted into 45,128 shares of common stock. In October 2002, the Company settled convertible notes payable of $100 through a cash payment of $86 and conversion of $14 of principal into 7,000 shares of common stock pursuant to the original terms of the note. In addition, $17 of related accrued interest was repaid in cash. In 2003 the remaining $15 of convertible note payable was converted into common stock.

During 2002, the remaining $167 of the deferred convertible notes payable extension costs was amortized to interest expense.

October 2003, April 2004 and August 2004 “PIPE” Transactions – In connection with the October 2003 PIPE transaction, as described in Note 7, the Company issued 657,293 warrants (the “2003 Investor Warrants”) with an initial exercise price of $5.29 per share to the investors and 65,729 warrants (the “2003 Placement Agent Warrants”) with an initial exercise price of $6.86 per share to its placement agent. The exercise price of the warrants is subject to adjustment pursuant to anti-dilution and other provisions. The fair value of the 2003 Investor Warrants and the 2003 Placement Agent Warrants was determined based on a fair market value of the Company’s common stock of $5.29 per share. The 2003 Investor Warrants and 2003 Placement Agent Warrants were valued at $2,531 and $191, respectively. The Company uses the Black-Scholes pricing model to value these warrants. The 2003 Investor Warrants and the 2003 Placement Agent Warrants were accounted for as freestanding derivative instruments in the consolidated balance sheet under the caption “Warrant Liabilities”. Changes in fair value are recognized as either a gain or loss in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities”.

In connection with the April 2004 PIPE transaction, as described in Note 7, the Company issued 618,056 warrants (the “April 2004 Investor Warrants”) and 61,806 warrants (the “April 2004 Placement Agent Warrants”) with an initial exercise price of $5.30 per share to the investors and to the placement agent, respectively. The exercise price of the warrants is subject to adjustment pursuant to anti-dilution and other provisions. The fair value of the April 2004 Investor Warrants and the April 2004 Placement Agent Warrants was determined based on a fair market value of the Company’s common stock of $4.41 per share. The April 2004 Investor Warrants and April 2004 Placement Agent Warrants were valued at $1,931 and $154, respectively. The Company uses the Black-Scholes pricing model to value these warrants. The April 2004 Investor Warrants and April 2004 Placement Agent Warrants were accounted for as freestanding derivative instruments in the consolidated balance sheet under the caption “Warrant Liabilities”. Changes in fair value are recognized as either a gain or loss in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities”.

In connection with the August 2004 PIPE transaction, as described in Note 7, the Company issued 2,000,000 warrants (the “August 2004 Investor Warrants”) and 100,000 warrants (the “August 2004 Placement Agent Warrants”) with an exercise price of $4.20 per share to the investors and to the placement agent, respectively. The exercise price of the warrants is subject to adjustment solely as a result of stock splits,

recapitalizations and similar events. The fair value of the August 2004 Investor Warrants and the August 2004 Placement Agent Warrants was determined based on a fair market value of the Company’s common stock of $3.39 per share. The August 2004 Investor Warrants and August 2004 Placement Agent Warrants were valued at $4,786 and $239, respectively. The Company uses the Black-Scholes pricing model to value these warrants. The August 2004 Investor Warrants and August 2004 Placement Agent Warrants were accounted for as freestanding derivative instruments in the consolidated balance sheet under the caption “Warrant Liabilities”. Changes in fair value are recognized as either a gain or loss in the consolidated statement of operations under the caption “Change in fair value of warrant liabilities”.

February 2006 “PIPE” Transaction – In February 2006, the Company issued $10,000 in aggregate principal amount of convertible debentures (the “Debentures”) together with warrants to purchase approximately 1,490,313 shares of the Company’s common stock (the “2006 Investor Warrants”). Additionally, in connection with issuance of the Debentures and Warrants, the placement agent received a fee of $550 and approximately 149,031 fully vested warrants (the “2006 Placement Agent Warrants”) to purchase shares of the Company’s common stock. Net proceeds were approximately $9,300, net of approximately $700 in direct transaction costs, including the placement agent fee. Redemptions and conversions of the Debentures are described in the table below.

The Debentures are convertible into 2,985,075 shares of the Company’s common stock at the option of the holder at any time prior to maturity at a conversion price of $3.35 per share, subject to adjustment for certain events described below.

The Debentures bear interest at 7% and are required to be redeemed in eighteen equal monthly installments beginning in August 2006 and continuing through January 2008. Interest is payable monthly beginning in July 2006. Each redemption installment and accrued interest may be settled in cash or in shares of common stock at the option of the Company. The number of shares deliverable under the share-settlement option is determined based on the lower of (a) $3.35 per share, as adjusted pursuant to the terms of the Debentures or (b) 90% applied to the average of the lowest five volume-weighted-average trading prices in a twenty day period immediately preceding each share settlement. If the share-settlement option is elected by the Company, the Company is required to make an estimated payment in shares approximately 30 days prior to the scheduled maturity date.

In the event of default, as defined in the Debentures, all amounts due and outstanding thereunder shall become, at the option of the holders, immediately due and payable in cash, in an amount that equals the sum of (i) the greater of (a) 130% of the outstanding balance plus all accrued and unpaid interest or (b) the conversion value of the Debentures, and (ii) all other amounts due in connection with the Debentures and associated agreements. Additionally, if a certain breach occurs under a related registration rights agreement, the Company will be required to pay, as liquidated damages, 2% per month of the outstanding balance of the Debentures, until such default is cured, up to a maximum of 24 months. Events of default include circumstances in which the Company either fails to have a registration statement for shares into which the Debentures can be converted be declared effective by the SEC within 180 days of the issuance date of the Debentures or that the registration statement’s effectiveness lapses for any reason. On March 29, 2006, the SEC declared effective the Company’s registration statement on Form S-3, which registered 7,300,000 shares of the Company’s common stock in connection with the Debentures and related 2006 Investor Warrants and 2006 Placement Agent Warrants.

At December 31, 2006, the Company did not have sufficient registered shares available to satisfy the conversion of the Debentures and the exercise of the 2006 Investor Warrants. The Company believes that it is not in default under provisions outlined above as a registration statement was in the process of being filed at December 31, 2006 with the SEC. As disclosed in Note 12, in March 2007 the Company has redeemed substantially all of the outstanding Debentures.

Table of Contents

As required by the transaction documents for these securities, the Company sought and on May 25, 2006 received approval from its shareholders to issue shares necessary to satisfy the Company’s obligations under the Debenture and 2006 Investor Warrants and 2006 Placement Agent Warrants.

The conversion price of the Debentures and exercise price of the 2006 Investor and Placement Agent Warrants are each subject to certain anti-dilution protections, including for stock splits, stock dividends, change in control events and dilutive issuances of common stock or common stock equivalents, such as stock options, at an effective price per share that is lower than the then conversion price. In the event of a dilutive issuance of common stock or common stock equivalents, the conversion price and exercise price would be reduced to equal the lower price per share of the subsequent transaction.

As described in Note 2, the Company has irrevocably elected to initially and subsequently measure the Debentures in their entirety at fair value with changes in fair value recognized as either a gain or loss in the consolidated statement of operations. Upon issuance of the Debentures, the Company allocated proceeds received to the Debentures and the 2006 Investor Warrants on a relative fair value basis. As a result of such allocation, the Company determined the initial carrying value of the Debentures to be $7,747. The Debentures were immediately marked to fair value, resulting in a liability in the amount of $9,126 and a charge to “Change in fair value of convertible debt instrument” of $1,379.

Upon issuance, the Company allocated $2,253 of the initial proceeds to the 2006 Investor Warrants and immediately marked them to fair value resulting in a derivative liability of $2,654 and a charge to “change in fair value of warrant liabilities” of $401. The Company paid approximately $700 in cash transaction costs and incurred another $266 in costs based upon the fair value of the 2006 Placement Agent Warrants. Such costs were expensed immediately as part of fair value adjustments required in connection with the Debentures and the Company’s irrevocable election to initially and subsequently measure the Debentures at fair value with changes in fair value recognized in earnings.

The debt discount in the amount of $2,253 (resulting from the allocation of proceeds) is being amortized to interest expense using the effective interest method over the expected term of the Debentures. The Company amortized $1,694 of this amount in 2006 with a corresponding increase in the carrying value of the Debentures. Of this amount $1,358 was charged to interest expense and $336 was recorded in additional paid-in capital as a result of conversions during 2006. An additional $492 in interest expense was recorded during 2006 based upon the 7% coupon rate.

The Company uses a binomial financial model to calculate the fair value of the Debentures and the 2006 Investor Warrants. The Company uses the Black-Scholes pricing model to calculate fair value of the 2006 Placement Agent Warrants, August 2004 Investor Warrants, August 2004 Placement Agent Warrants, April 2004 Investor Warrants, April 2004 Placement Agent Warrants, 2003 Investor Warrants, and the 2003 Placement Agent Warrants (expired unexercised in 2006).

7. STOCKHOLDERS’ (DEFICIT) EQUITY

The Company has raised capital through a number of debt and equity financing transactions. The following provides a chronological description of the Company’s equity financings and certain warrants issued in connection with such equity financings.

2001 Private Placement – From May 25, 2001 through December 3, 2001, the Company sold a total of 689,300 shares of common stock for proceeds of $2,221, net of $17 of issuance costs through a private placement of securities (the “2001 Private Placement”).

In connection with the 2001 Private Placement, the Company issued 339,200 and 350,100 warrants to purchase common stock at $6.50 and $5.00 per share, respectively. The Company, upon giving written notice, may accelerate the exercise of the warrants and effect an early termination thereof in the event of either of the following: (i) the Company files a new drug application (“NDA”) with the Food and Drug Administration or (ii) the market price exceeds $11.00 and $10.00 for warrants with exercise prices of $6.50 and $5.00, respectively on any 10 trading days within a period of 20 consecutive trading days, as defined. In the event of acceleration, the unexercised warrants automatically terminate without payment by the Company upon the thirtieth day following the written notice. The Company valued the warrants at $886, based on a deemed fair market value of the Company’s common stock of $2.28 per share. All of these warrants expired unexercised in 2005.

As described in Note 6, in August 2001, the Company offered warrants to holders of its outstanding convertible notes as an inducement to convert prior to the maturity of the notes. Holders representing $1,126 of the outstanding principal and accrued interest chose to convert at a conversion price of $2.00 per share and received 598,229 common shares and 562,801 warrants. These warrants have an exercise price of $6.50 per share and are immediately exercisable. The Company may, upon giving written notice, accelerate the exercise of the warrant and effect an early termination thereof in the event of either of the following: (i) the Company files a new drug application (“NDA”) with the Food and Drug Administration, or (ii) the market price exceeds $11.00 on any 10 trading days within a period of 20 consecutive trading days as defined. In the event of acceleration, the unexercised warrants automatically terminate without payment by the Company upon the thirtieth day following the written notice. The Company valued the warrants at $503 based on a deemed fair market value of the Company’s common stock of $2.28 per share. The value of the warrants has been recorded as a debt conversion expense. All of these warrants expired unexercised in 2005.

Public Offering – On December 13, 2001, the Company commenced a public offering of 1,428,572 shares of common stock, at a price to the public of $3.50 per share. The Company concluded the offering on June 30, 2002. The Company sold 185,999 shares of common stock in this offering for proceeds of $602, net of $49 of issuance costs, all in 2002.

2002 Private Placement – In September 2002, the Company began a private placement (the “2002 Private Placement”) of up to 10,000,000 shares of common stock at $1.00 per share, exempt from registration pursuant to Rule 506 of Regulation D under the Securities Act of 1933. As of December 31, 2002, the Company had sold 3,223,360 shares for proceeds of $2,861, net of issuance costs of $212 and stock subscription receivable of $150, which related to shares purchased but for which payment had not been received as of December 31, 2002. This offering was closed on January 14, 2003, although subsequent to year end the Company sold an additional 1,088,000 shares for additional proceeds of $1,070, net of $18 of offering costs.

The Company compensated a registered investment adviser with respect to shares purchased by its clients. As of December 31, 2002, the adviser was entitled to receive 173,500 shares of common stock. The Company also agreed to compensate a finder registered under applicable law, and such finder’s agents, for identifying qualified investors. As of December 31, 2002, one of the finder’s agents was entitled to receive 750 shares of common stock. On January 14, 2003, the Company closed the 2002 Private Placement, at which point the Company agreed to issue the adviser an additional 2,500 shares, and the finder and its other agent an aggregate of 9,750 additional shares and $3 in cash in connection with the shares sold subsequent to December 31, 2002 and through the closing date.

Shares placed by such registered adviser, finder and finder’s agent were accounted for as offering costs and valued at $1.00 per share, consistent with the price paid for the shares placed in the offering. Such offering costs were netted against the proceeds of the 2002 Private Placement. Since none of the 174,250 shares had been issued as of December 31, 2002, the Company recorded the obligation to issue such shares as offering costs payable. The additional 12,250 shares issued in January 2003 were also valued at $1.00 per share and included in the $18 offering costs recorded at the closing. These shares were subsequently issued in 2003.

During 2002, the Company also agreed to issue 2,100 shares of common stock to an employee for finding investors in connection with the 2002 Private Placement. None of the shares had been issued as of December 31, 2002. These shares were subsequently issued in 2003. Accordingly, the Company recorded the obligation to general and administrative expenses in the statement of operations in the amount of $6. On January 14, 2003, the Company closed the 2002 Private Placement, at which point the Company agreed to issue such employee an additional 7,000 shares in connection with shares sold subsequent to December 31, 2002 and through the closing date. The Company recorded an additional obligation of $27 to general and administrative expenses in 2003 representing the fair value of the additional 7,000 shares.

May 2003 Private Placement – In May 2003, the Company began a private placement of up to 2.5 million shares of common stock at $2.00 per share, exempt from registration pursuant to Rule 506 of Regulation D under the Securities Act of 1933. As of the closing on July 15, 2003, the Company had sold 2,399,500 shares of common stock for proceeds of $4,671, net of issuance costs of $128. In connection with this offering the Company issued 109,613 common stock warrants (exercisable at $5.40 per share) to its placement agents.

The Company valued the warrants at $261 using the Black-Scholes pricing model and recorded the warrant value as offering costs with a corresponding increase to additional paid-in capital. These warrants expired unexercised in 2006.

8. STOCK BASED COMPENSATION

Summary of Stock-Based Compensation Plans – In October 2001, the Company’s Board of Directors adopted the Pro-Pharmaceuticals, Inc. 2001 Stock Incentive Plan (the “Incentive Plan”), which permits awards of incentive and nonqualified stock options and other forms of incentive compensation to employees and non-employees such as directors and consultants. The Board reserved 2,000,000 shares of common stock for issuance upon exercise of grants made under the Incentive Plan. Options granted under the Incentive Plan vest either immediately or over a period of up to three years, and expire 3 years to 10 years from the grant date. In 2004, the stockholders approved an increase in the number of shares of common stock subject to the Incentive Plan by 3,000,000 such that the total number of shares subject to awards under the Incentive Plan is 5,000,000. At December 31, 2006, there were 2,484,000 shares available for future grant under the Incentive Plan.

In 2003, the stockholders approved the Pro-Pharmaceuticals, Inc. 2003 Non-Employee Director Stock Option Plan (the “Director Plan”), which permits awards of stock options to non-employee directors. The stockholders reserved 1,000,000 shares of common stock for issuance upon exercise of grants made under the Director Plan. At December 31, 2006, there were 871,250 shares available for future grant under the Director Plan.

Table of Contents

In addition, the Company has awarded 464,604 non-plan stock option grants to non-employees. The non-plan grants have vesting periods and expiration dates similar to those options granted under the Incentive Plan. All 464,604 non-plan grants are outstanding at December 31, 2006.

Change in Accounting for Stock-Based Compensation – As disclosed in Note 2, on January 1, 2006, the Company adopted SFAS No. 123(R). Due to the adoption of SFAS No. 123(R), the Company’s results for the year ended December 31, 2006 include incremental compensation related to stock options totaling $416.

Stock-based compensation expense for both employees and non-employees totaled $416, $22 and $163 in 2006, 2005 and 2004 respectively. Members of the Board of Directors receive stock options for each Board and Committee meeting attended. The options are typically granted in the year following service. The Company expenses the value of stock options as earned. In 2006 Board members earned approximately 42 stock options. The $416 of 2006 stock-based compensation expense includes $24 related to Board of Director stock options earned but not granted. These options were granted on March 8, 2007.

Prior to January 1, 2006, the Company accounted for stock-based compensation plans in accordance with the provisions of APB Opinion No. 25, as permitted by SFAS No. 123. Under APB Opinion No. 25, the Company was not required to recognize compensation expense for the cost of stock options, when such options had an exercise price equal to the market price at the date of grant. If the employee fair value based method as prescribed by SFAS No. 123 had been applied by the Company, the effect on net loss and loss per share for 2005 and 2004 and Net loss for the cumulative period from inception to December 31, 2006 would have been as follows:

 

     2005     2004  

Net loss

   $ (6,855 )   $ (3,770 )

Deduct stock-based compensation determined under the fair-value method

     (287 )     (749 )
                

Net loss—pro forma

   $ (7,142 )   $ (4,519 )
                

Basic and diluted loss per share:

    

As reported

   $ (0.25 )   $ (0.15 )

Pro forma

   $ (0.26 )   $ (0.18 )

The 2005 stock-based compensation amount of $287 includes $59 related to 34,000 options for Board of Directors service which were earned in 2005 but not granted until March 2006.

The fair value of the equity instruments granted to employees and non-employees, including options and, is determined using the Black-Scholes option-pricing model. Key assumptions used to apply this option-pricing model are as follows:

 

     2006     2005     2004     Cumulative
Period from
Inception
(July 10, 2000) to
December 31,
2006
 

Risk-free interest rate

   4.75 %   3.48 %   3.11 %   2.95 %

Expected life of the options

   5 years     3 years     3 years     3.26 years  

Expected volatility of the underlying stock

   65 %   75 %   95 %   89 %

Expected dividend rate

   None     None     None     None  

As noted above, the fair value of stock options is determined by using the Black-Scholes option pricing model and applying the multiple-option valuation approach to the stock option valuation. In general employee options vest over a period of three years. Board of Director and other options vest upon grant. For all options granted since January 1, 2006 the Company has used five years as the option term which represents the estimated life of options granted. Prior to January 1, 2006 the Company used three years as the option term.

The volatility of the common stock is estimated using a combination of historical and implied volatility, as discussed in SEC Staff Accounting Bulletin No. 107. By using this combination, the Company is taking into consideration the historical realized volatility, as well as factoring in estimates of future volatility that the

 

F-19


Table of Contents

Company believes will differ from historical volatility as a result of the market performance of the common stock, the volume of activity of the underlying shares, the availability of actively traded common stock options, and overall market conditions.

The risk-free interest rate used in the Black-Scholes option pricing model is determined by looking at historical U.S. Treasury zero-coupon bond issues with terms equal to the expected terms of the equity awards. In addition, an expected dividend yield of zero is used in the option valuation model, because the Company does not expect to pay any cash dividends in the foreseeable future. Lastly, in accordance with SFAS No. 123(R), the Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. In order to determine an estimated pre-vesting option forfeiture rate, the Company used historical forfeiture data. This estimated forfeiture rate has been applied to all unvested options outstanding as of January 1, 2006 and to all options granted since January 1, 2006. Therefore, stock-based compensation expense is recorded only for those options that are expected to vest. At December 31, 2006, the Company does not anticipate any awards will be forfeited in the calculation of compensation expense due to the limited number of employees that receive stock option grants and the Company’s historical employee turnover.

The following table summarizes the stock option activity in the stock based compensation plans from January 1, 2004 through December 31, 2006:

The weighted-average grant-date fair values of options granted during 2006, 2005 and 2004 were $3.75, $3.31 and $2.52, respectively. As of December 31, 2006 there were 516,666 of unvested options which will vest as follows: 236,667 in 2007, 165,001 in 2008 and 114,998 in 2009. Total expected unrecognized compensation cost related to such unvested options is $707, which is expected to be recognized over a weighted–average period of 1.1 years. As of December 31, 2006, there is no aggregate intrinsic value of outstanding options, fully vested options or exercisable options, based on the Company’s closing common stock price of $.45 as of December 31, 2006.

At the time of issuance, these options were valued at $239 based on a deemed fair market value of the Company’s common stock of $2.28 per share. A portion of these options vested during fiscal years 2001 and 2002, and the remainder vested in 2003. The Company recorded fair value adjustments of $28 and $16 related to the unvested consultant options during 2003 and 2002, respectively.

These options were valued at $11 using the Black-Scholes option-pricing model, based on a deemed fair market value of the Company’s common stock of $3.50 per share. During 2002, the Company recorded a $41 charge to stock compensation expense related to the 20,000 options that vested during the year. As of December 31, 2002, the Company had deferred compensation of $11 that related to the remaining unvested options, which was recognized in 2003.

In June 2003, the Company entered into a third agreement with the same non-employee, by which the Company granted 24,000 options effective retroactively to March 1, 2003, which vest at a rate of 2,000 options per month as services are performed.

The Company recorded a $122 charge to stock compensation expense in 2003 related to these awards.

In October 2003, in connection with the resignation of its former Chief Financial Officer, the Company accelerated the vesting on 100,000 options granted to such officer in September 2003 at an exercise price of $4.05, which was equal to the fair market value of the common stock on the date of grant. As the fair market value of the common stock was $4.45 per share at the time the vesting was accelerated, the Company recorded a $40 charge to stock compensation expense as required under APB No. 25 and related interpretations. Also, in October 2003, such officer exercised on a cashless basis 50,000 options at an exercise price of $2.97 per share resulting in the issuance of 16,629 shares. As the fair market value of the Company’s common stock on the date of exercise was $4.45 per share, the Company recorded a charge of $74 to stock compensation expense in 2003 related to the exercise of these options.

In March 2004, the Company issued 25,000 options in fulfillment of a September 2003 agreement with an investor relations firm. The agreement obligated the Company to pay a monthly retainer and issue options at a rate of 5,000 options per month, up to a maximum of 100,000 options, exercisable at $5.80 per share as services are performed. The Company concluded the engagement in February 2004. The options are exercisable immediately and expire on March 26, 2007. Accordingly, the Company recorded $29 as stock compensation expense in 2003 on the 15,000 options that vested as of December 31, 2003 and an additional stock compensation expense of $23 in 2004 on the 10,000 options that vested in January and February 2004.

In April 2004, the Company entered into an agreement with an investor relations firm. The agreement obligated the Company to pay a monthly retainer and issue options at a rate of 5,000 per month up to a maximum of 60,000 options exercisable at $5.16 per share as services are performed. During 2004, 45,000 options were earned but not issued. During 2005 15,000 options were earned and the full 60,000 options were issued. The Company recorded $67 in 2004 and $14 in 2005 as stock compensation expense related to this agreement.

The options are exercisable immediately and expire three years from the agreement date.

In November 2005, the Company issued 5,000 options to a member of the Scientific Advisory Board for consulting services. The options were exercisable immediately at $2.61 per share. These options were valued using the Black-Scholes option-pricing model based on a deemed fair market value of the Company’s common stock of $2.61 per share which was the fair market value at the date of the grant. The Company recorded a $7 charge to stock compensation expense in 2005 related to this award.

9. EARNINGS PER SHARE

Basic loss per share is based on the weighted-average number of common shares outstanding during each period. Diluted loss per share is based on basic shares as determined above plus the incremental shares that would be issued upon the assumed exercise of in-the-money stock options and warrants using the treasury stock method and convertible debenture using the if-converted method. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share. For the years ended December 31, 2006, 2005 and 2004, all stock options, warrants and potential shares related to conversion of the convertible debentures were excluded from the computation of diluted net income (loss) per share. Dilutive shares which could exist pursuant to the exercise of outstanding stock options and warrants at December 31, 2006, 2005 and 2004 totaled approximately 8,245,853, 6,397,851 and 7,377,952 respectively. These amounts were not included in the calculation because their affect would have been anti-dilutive. At December 31, 2006 the shares that would be issued upon conversion of the convertible debt was excluded from the computation of diluted net loss per share as the effect would have been anti-dilutive.

Contingency – In January 2004, Dr. Platt, the Company’s Chairman and Chief Executive Officer, filed a lawsuit in Massachusetts Superior Court against GlycoGenesys, Inc. for various claims including breach of contract. In its filing in February 2004, GlycoGenesys asserted counterclaims against the Company and Dr. Platt alleging tortious interference and misappropriation of proprietary rights. The counterclaims seek monetary damages and injunctive relief related to the Company’s intellectual property. In March 2004, the Company and Dr. Platt answered the counterclaims and denied any liability. In June 2004, the Court allowed, without opposition, a motion of GlycoGenesys for leave to file a supplemental counterclaim

against the Company for defamation and unfair competition. On February 2, 2006, GlycoGenesys filed a voluntary petition for protection under Chapter 11 of the U.S. Bankruptcy Code, which stayed the counterclaim litigation proceedings. On June 1, 2006, the bankruptcy court approved a motion by GlycoGenesys to convert the proceeding to Chapter 7 liquidation. On October 23, 2006, the judge issued an order allowing the liquidation sale of certain GlycoGenesys assets to Marlborough Research and Development, Inc. including the counterclaim lawsuit. Marlborough Research and Development, Inc. has changed its name to Prospect Therapeutics, Inc. and has informed the Company that it intends to pursue the counterclaim lawsuit against the Company and Dr. Platt. The Company believes these claims are without merit and intends to contest them vigorously. Additionally, the Company believes that any impact on the financial statements is neither probable or reasonably estimable and therefore no amounts have been recorded as of December 31, 2006.

Pursuant to Board approval, the Company has agreed to indemnify Dr. Platt for the expenses of his defense of the counterclaims. In 2006 the Company incurred approximately $11 of expenses in connection with this defense. Through December 31, 2006 the Company has incurred cumulative expenses of approximately $438 in connection with this defense.

On January 28, 2005, the Company filed a request with the U.S. Patent and Trademark Office (USPTO) for an inter partes re-examination of U.S. Patent No. 6,680,306 owned by GlycoGenesys, Inc. because the Company believes that the invention claimed in this patent is anticipated by other inventions (technically, “prior art”), including the Company’s U.S. Patent No. 6,645,946 for DAVANAT®. In an October 18, 2005 action, the USPTO agreed with the Company’s argument that all claims stated in the ‘306 patent are anticipated by prior art. On December 19, 2005, GlycoGenesys filed a response to the USPTO, and on January 18, 2006, the Company responded to the GlycoGenesys submission. The matter is now before the USPTO for a final decision. The Company believes that the USPTO actions to date support its belief that the invention claimed in the DAVANAT patent is prior art relative to the GlycoGenesys patent.

In the ordinary course of business, the Company may from time to time be involved in other legal matters that in the Company’s estimation will not have a material adverse impact on it. The Company records accruals for such contingencies to the extent that the Company concludes that their occurrence is probable and the related damages are estimable.

As of December 31, 2006, the Company has federal and state net operating loss carryforwards totaling approximately $29,885 and $27,752, respectively, which expire through 2026. In addition, the Company has federal and state research and development and investment tax credits of approximately $586 and $449, respectively, which expire through 2021. If substantial changes in the Company’s ownership should occur as defined by Section 382 of the Internal Revenue Code (the “Code”), there could be annual limitations on the amount of carryforwards which may be realized in future periods. Because of the Company’s limited operating history and its recorded losses, management has provided, in each of the last two years, a 100% allowance against the Company’s net deferred tax assets.

 

12. SUBSEQUENT EVENTS

Subsequent to year end the Company has issued 2,640,801 shares of common stock to satisfy redemptions in accordance with the terms of the convertible debenture agreement.

On March 20, 2007, the Company entered into a Waiver and Exchange Agreement (the “Agreement”) with six of seven remaining holders of the Company’s 7% Convertible Debentures (the “Debentures”), representing $3,889 of the $4,444 outstanding principal. Pursuant to the Agreement, on March 21, 2007, the Company issued approximately 5.2 million shares of its common stock at $0.75 per share to discharge the principal, accrued and unpaid interest and any other obligations under the Debentures subject to the Agreement. The Agreement also provided that the exercise price of the common stock purchase warrants issued by the Company contemporaneously with the Debentures on February 14, 2006, would be reduced to $1.00 (and the number of shares issuable on exercise proportionately increased) to take into account the dilutive effect of this transaction. If all the warrants were exercised for cash payment at the reduced exercise price, the Company would issue approximately 5 million shares. The Agreement also provided that the Company (i) may not make payments in shares of its common stock on any outstanding Debentures unless the price per share is at least $0.85, (ii) may not offer or sell its securities during the 6-month period after this transaction without also offering them to the former Debenture holders, and (iii) may not offer to sell its securities for 30 calendar days after the transaction at an effective price per share of its common stock lower than $0.75.

14. RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

Subsequent to the issuance of the 2005 consolidated financial statements the Company determined that the October 2003 Warrants, the April 2004 Warrants, and the August 2004 Warrants (collectively, the “Restated Warrants”) that were issued as part of its equity finance transactions in October 2003, April 2004 and August 2004, respectively, and were accounted for in stockholders’ equity at their relative fair value upon issuance, should have been accounted for as derivative liabilities in accordance with SFAS 133. The Restated Warrants did not meet any of the scope exceptions allowed by SFAS 133. Specifically, the warrants did not meet the criteria in paragraph 11(a) of SFAS 133 that a contract should not be considered a derivative instrument if it is (1) indexed to its own stock and (2) classified in stockholders’ equity. The Restated Warrants, when classified as derivative liabilities are required to be initially recorded at fair value and to be marked to fair value at the end of each reporting period, which results in a non-cash charge or credit to other income and expense in the Company’s consolidated statement of operations.

The consolidated financial statements for the years ended December 31, 2005 and 2004 have been restated.

The following tables summarize the impact of the restatement discussed above on the previously issued consolidated balance sheet as of December 31, 2005 and the previously issued consolidated statements of operations and cash flows for the years ended December 31, 2005 and 2004. The effects on previously issued quarterly financial data for fiscal 2006 and 2005 are summarized in Note 13.
