                               PROSPECTUS SUMMARY

OUR COMPANY

         We are a biopharmaceutical company focused on the acquisition,
development and commercialization of novel pharmaceutical products for the
treatment of life-threatening diseases, including diabetes and cancer. To date,
we have not received approval for the sale of any of our drug candidates in any
market and, therefore, have not generated any revenues from our drug candidates.
We have two product candidates in late-stage clinical development: Sulodexide,
or KRX-101, for the treatment of diabetic nephropathy, a life-threatening kidney
disease caused by diabetes, and Perifosine, or KRX-0401, for the treatment of
multiple forms of cancer.

         Our lead compound under development is KRX-101, to which we have an
exclusive license in North America, Japan and other markets. A randomized,
double-blind, placebo-controlled, Phase II study of the use of Sulodexide for
treatment of diabetic nephropathy in 223 patients was conducted in Europe and
the results of this study were published in the June 2002 issue of the Journal
of the American Society of Nephrology. The results of this Phase II study showed
a dose-dependent reduction in proteinuria or pathological urinary albumin
excretion rates. In 2001, KRX-101 was granted Fast-Track designation for the
treatment of diabetic nephropathy and, in 2002, we announced that the Food and
Drug Administration, or FDA, had agreed, in principle, to permit us to avail
ourselves of the accelerated approval process under subpart H of the FDA's
regulations governing applications for the approval to market a new drug.

         In the third quarter of 2003, we announced that the Collaborative Study
Group, or CSG, the largest standing renal clinical trial group in the United
States comprised of academic and tertiary nephrology care centers, will conduct
the U.S.-based Phase II/III clinical program for KRX-101 for the treatment of
diabetic nephropathy. The CSG has conducted multiple large-scale clinical trials
resulting in over 40 publications in peer-reviewed journals. The CSG conducted
the pivotal studies for two of the three drugs that are currently approved for
treatment of diabetic nephropathy. In the fourth quarter of 2003, we initiated a
multi-center, Phase II/III clinical program for our diabetic nephropathy drug
candidate, KRX-101.

         In the first quarter of 2004, we announced that we had acquired ACCESS
Oncology, Inc. and its subsidiaries, or ACCESS Oncology, a privately-held
cancer-focused biotechnology company. The acquired drug portfolio includes three
clinical stage compounds, designated as KRX-0401, KRX-0402, and KRX-0403.
KRX-0401 is a novel, first-in-class, oral AKT-inhibitor that has demonstrated
preliminary single agent anti-tumor activity in Phase I studies and is currently
in a broad Phase II clinical program evaluating KRX-0401 as a single agent in
the treatment of multiple forms of cancer. The current Phase II program is being
conducted and funded by the National Cancer Institute, or NCI, a department of
the National Institutes of Health, or NIH, under a Cooperative Research and
Development Agreement, or CRADA, arrangement. Additionally, we are planning to
conduct a series of additional Phase II clinical trials for KRX-0401 both as a
single agent and in combination with other anti-cancer therapies. The acquired
cancer portfolio also includes KRX-0402, an inhibitor of DNA repair, which is
also being studied by the NCI under a CRADA arrangement in multiple clinical
trials. In addition, the portfolio includes KRX-0403, which is a novel spindle
poison in the same general class as Navelbine(R), Taxol(R) and Taxotere(R).
KRX-0403 has completed a Phase I study. In addition, as a part of the
acquisition of ACCESS Oncology, we acquired Online Collaborative Oncology Group,
Inc., or OCOG, a subsidiary of ACCESS Oncology which provides clinical research
and site management services to other biotechnology and pharmaceuticals
companies.

         In the fourth quarter of 2003, we completed a private placement
transaction raising approximately $15 million in gross proceeds. Funds raised
from our private placement offerings not only provide us with additional capital
to support our planned clinical programs for KRX-101, KRX-0401 and the other
oncology drug candidates within our portfolio, but also provide us with added
flexibility in our in-licensing and product acquisition program, which is
designed to expand our product pipeline with additional drug candidates.

         We were incorporated in Delaware in October 1998. We commenced
operations in November 1999, following our acquisition of substantially all of
the assets and certain of the liabilities of Partec Ltd., our predecessor
company that began its operations in January 1997. Since commencing operations,
our activities have been primarily devoted to developing our technologies and
drug candidates, raising capital, purchasing assets for our former corporate
offices and laboratory facilities and recruiting personnel. We are a development
stage company and have no product sales to date. Our major sources of working
capital have been proceeds from various private placements of equity securities
and from our initial public offering.

         Our principal executive offices are located at 750 Lexington Avenue,
New York, New York 10022, and our telephone number is (212) 531-5965. We
maintain a website on the Internet at www.keryx.com and our e-mail



                                       1


address is info@keryx.com. Our Internet website, and the information contained
on it, are not to be considered part of this prospectus.

                               RECENT DEVELOPMENTS

         On February 5, 2004, we completed the acquisition of ACCESS Oncology, a
Delaware corporation. ACCESS Oncology is a biopharmaceutical company focused on
acquiring, developing and marketing novel therapeutics for cancer and related
conditions. The transaction was structured as a merger of AXO Acquisition Corp.,
a Delaware corporation and our wholly-owned subsidiary, with and into ACCESS
Oncology, with ACCESS Oncology remaining as the surviving corporation. As a
result of the transaction, ACCESS Oncology is now our wholly-owned subsidiary.

         Under the terms of the merger agreement, as amended, at the effective
time of the merger the outstanding shares of preferred stock of ACCESS Oncology
were converted into the right to receive, at the election of each preferred
stockholder, either (i) shares of our common stock to be issued approximately 30
days after the merger having a value (as determined in accordance with the
merger agreement) equal to the value of the liquidation preference associated
with the stockholder's shares of preferred stock, or (ii) a portion of the
contingent milestone consideration (described below) payable to the holders of
ACCESS Oncology common stock and securities convertible into ACCESS Oncology
common stock in an amount equal to what the preferred stockholder would have
received had he converted his preferred stock immediately before the
consummation of the merger. At the effective time of the merger, each share of
ACCESS Oncology common stock, including shares issuable upon the exercise of
options exercised before March 1, 2004 and upon the exercise of outstanding
warrants, was converted into the right to share in milestone consideration pro
rata with such other holders of ACCESS Oncology common stock. Pursuant to the
terms of the merger agreement, we must file a registration statement on or prior
to the 45th day following each distribution of merger consideration upon the
occurrence of certain triggering events, covering the resale of all of the
shares of our common stock issued in such distribution of merger consideration.
This prospectus is part of the registration statement filed to meet certain of
our obligations under the registration rights agreement.

         On February 17, 2004, we completed a private placement in which
3,200,000 shares of our common stock were sold for $10.00 per share to
institutional investors. We entered into a registration rights agreement with
the selling stockholders on or about February 17, 2004. The registration rights
agreement provided that we must file a registration statement on or prior to the
30th day following February 17, 2004, covering the resale of all of the shares
of our common stock sold by us in the private placement. The registration
statement was filed with the Securities and Exchange Commission on March 16,
2004.



                                       2


                                  RISK FACTORS

RISKS RELATING TO OUR BUSINESS

WE HAVE A LIMITED OPERATING HISTORY AND HAVE INCURRED SUBSTANTIAL OPERATING
LOSSES SINCE OUR INCEPTION. WE EXPECT TO CONTINUE TO INCUR LOSSES IN THE FUTURE
AND MAY NEVER BECOME PROFITABLE.

         We have a limited operating history. You should consider our prospects
in light of the risks and difficulties frequently encountered by early stage
companies. In addition, we have incurred operating losses since our inception,
expect to continue to incur operating losses for the foreseeable future and may
never become profitable. As of December 31, 2003, we had an accumulated deficit
of approximately $54.6 million. As we expand our research and development
efforts, we will incur increasing losses. We may continue to incur substantial
operating losses even if we begin to generate revenues from our drug candidates
or technologies.

         We have not yet commercialized any products or technologies and cannot
be sure we will ever be able to do so. Even if we commercialize one or more of
our drug candidates or technologies, we may not become profitable. Our ability
to achieve profitability depends on a number of factors, including our ability
to complete our development efforts, obtain regulatory approval for our drug
candidates and successfully commercialize our drug candidates and technologies.

IF WE ARE UNABLE TO SUCCESSFULLY COMPLETE OUR CLINICAL TRIAL PROGRAMS FOR
KRX-101 OR OUR RECENTLY ACQUIRED CANCER COMPOUNDS, OR IF SUCH CLINICAL TRIALS
TAKE LONGER TO COMPLETE THAN WE PROJECT, OUR ABILITY TO ACHIEVE OUR CURRENT
BUSINESS STRATEGY WILL BE ADVERSELY AFFECTED.

         Whether or not and how quickly we complete clinical trials is dependent
in part upon the rate at which we are able to engage clinical trial sites and,
thereafter, the rate of enrollment of patients. Patient enrollment is a function
of many factors, including the size of the patient population, the proximity of
patients to clinical sites, the eligibility criteria for the study and the
existence of competitive clinical trials. If we experience delays in identifying
and contracting with sites and/or in patient enrollment in our clinical trial
programs, we may incur additional costs and delays in our development programs,
and may not be able to complete our clinical trials on a cost-effective basis.

         Additionally, we have submitted a subpart H clinical development plan
to the FDA for the clinical development of KRX-101 for diabetic nephropathy. A
final agreement on the specifics of our clinical program for that development
plan has not been agreed to with the FDA and we cannot give any assurance that
an acceptable final agreement on the specifics of such clinical program will
ever be reached with the FDA. In fact, based on the FDA's comments to our most
recent submission, we believe that additional discussions with the FDA will be
required prior to final agreement on the specifics of our subpart H accelerated
approval clinical program. We cannot assure you as to when those discussions
will take place or that the results of such discussions will be satisfactory to
us. Additionally, the FDA has stated that based on the novelty of the approach
that we have discussed with them, they may want to refer our proposed approach
to the Cardio-Renal Advisory Committee.

         Moreover, even if we are able to reach final agreement with the FDA
regarding the specifics of an accelerated approval approach, no assurance can be
given that we will be able to meet the requirements set forth in such agreement.
The subpart H process is complex and requires precise execution. Many companies
who have been granted the right to utilize an accelerated approval approach have
failed to obtain approval. The clinical timeline, scope and consequent cost for
the development of KRX-101 will depend, in part, on the final outcome of our
discussions with the FDA. Moreover, negative or inconclusive results from the
clinical trials we hope to conduct or adverse medical events could cause us to
have to repeat or terminate the clinical trials. Accordingly, we may not be able
to complete the clinical trials within an acceptable time frame, if at all.

IF OUR DRUG CANDIDATES DO NOT RECEIVE THE NECESSARY REGULATORY APPROVALS, WE
WILL BE UNABLE TO COMMERCIALIZE OUR DRUG CANDIDATES.

         We have not received, and may never receive, regulatory approval for
commercial sale for any of our drug candidates. We will need to conduct
significant additional research and human testing before we can apply for
product approval with the FDA or with regulatory authorities of other countries.
Preclinical testing and clinical development are long, expensive and uncertain
processes. Satisfaction of regulatory requirements typically depends on the
nature, complexity and novelty of the product and requires the expenditure of
substantial resources. Data obtained from preclinical and clinical tests can be
interpreted in different ways, which could delay, limit or prevent



                                       3


regulatory approval. It may take us many years to complete the testing of our
drug candidates and failure can occur at any stage of this process. Negative or
inconclusive results or medical events during a clinical trial could cause us to
delay or terminate our development efforts.

         Clinical trials also have a high risk of failure. A number of companies
in the pharmaceutical industry, including biotechnology companies, have suffered
significant setbacks in advanced clinical trials, even after achieving promising
results in earlier trials. If we experience delays in the testing or approval
process or if we need to perform more or larger clinical trials than originally
planned, our financial results and the commercial prospects for our drug
candidates may be materially impaired. In addition, we have limited experience
in conducting and managing the clinical trials necessary to obtain regulatory
approval in the United States and abroad and, accordingly, may encounter
unforeseen problems and delays in the approval process.

BECAUSE WE LICENSE OUR PROPRIETARY TECHNOLOGIES, TERMINATION OF THESE AGREEMENTS
WOULD PREVENT US FROM DEVELOPING OUR DRUG CANDIDATES.

         We do not own any of our drug candidates. We have licensed these drugs
from others. These license agreements require us to meet development or
financing milestones and impose development and commercialization due diligence
on us. In addition, under these agreements we must pay royalties on sales of
products resulting from licensed technologies and pay the patent filing,
prosecution and maintenance costs related to the licenses. If we do not meet our
obligations in a timely manner or if we otherwise breach the terms of our
agreements, our licensors could terminate the agreements and we would lose the
rights to our drug candidates.

BECAUSE OUR BUSINESS MODEL IS BASED, IN PART, ON THE ACQUISITION OR IN-LICENSING
OF ADDITIONAL CLINICAL PRODUCT CANDIDATES, IF WE FAIL TO ACQUIRE OR IN-LICENSE
SUCH CLINICAL PRODUCT CANDIDATES, OUR FUTURE GROWTH PROSPECTS MAY BE
SUBSTANTIALLY IMPAIRED.

         As a major part of our business strategy, we plan to continue to
acquire or in-license clinical stage product candidates. If we fail to acquire
or in-license such product candidates, we may not achieve expectations of our
future performance. Because we do not intend to engage in significant discovery
research, we must rely on third parties to sell or license new product
opportunities to us. Other companies, including some with substantially greater
financial, development, marketing and sales resources, are competing with us to
acquire or in-license such products or product candidates. We may not be able to
acquire or in-license rights to additional products or product candidates on
acceptable terms, if at all.

IF WE DO NOT ESTABLISH OR MAINTAIN DRUG DEVELOPMENT AND MARKETING ARRANGEMENTS
WITH THIRD PARTIES, WE MAY BE UNABLE TO COMMERCIALIZE OUR TECHNOLOGIES INTO
PRODUCTS.

         We are an emerging company and do not possess all of the capabilities
to fully commercialize our product candidates on our own. From time to time, we
may need to contract with third parties to:

         o    assist us in developing, testing and obtaining regulatory approval
              for and commercializing some of our compounds and technologies;
              and

         o    market and distribute our drug candidates.

         We can provide no assurance that we will be able to successfully enter
into agreements with such partners on terms that are acceptable to us. If we are
unable to successfully contract with third parties for these services when
needed, or if existing arrangements for these services are terminated, whether
or not through our actions, or if such third parties do not fully perform under
these arrangements, we may have to delay, scale back or end one or more of our
drug development programs or seek to develop or commercialize our technologies
independently, which could result in delays. Further, such failure could result
in the termination of license rights to one or more of our technologies.
Moreover, if these development or marketing agreements take the form of a
partnership or strategic alliance, such arrangements may provide our
collaborators with significant discretion in determining the efforts and
resources that they will apply to the development and commercialization of
products based on our technologies. Accordingly, to the extent that we rely on
third parties to research, develop or commercialize products based on our
technologies, we are unable to control whether such products will be
scientifically or commercially successful.



                                       4


EVEN IF WE OBTAIN FDA APPROVAL TO MARKET OUR PRODUCT CANDIDATES, IF OUR PRODUCTS
FAIL TO ACHIEVE MARKET ACCEPTANCE, WE WILL NEVER RECORD MEANINGFUL REVENUES.

         Even if our products are approved for sale, they may not be
commercially successful in the marketplace. Market acceptance of our product
candidates will depend on a number of factors, including:

         o    perceptions by members of the health care community, including
              physicians, of the safety and efficacy of our product candidates;

         o    the rates of adoption of our products by medical practitioners and
              the target populations for our products;


         o    the potential advantages that our product candidates offer over
              existing treatment methods;

         o    the cost-effectiveness of our product candidates relative to
              competing products;

         o    the availability of government or third-party payor reimbursement
              for our product candidates;

         o    the side effects or unfavorable publicity concerning our products
              or similar products; and

         o    the effectiveness of our sales, marketing and distribution
              efforts.

         Because we expect sales of our product candidates, if approved, to
generate substantially all of our revenues in the long-term, the failure of our
drugs to find market acceptance would harm our business and could require us to
seek additional financing or other sources of revenue.

WE RELY ON THIRD PARTIES TO MANUFACTURE OUR PRODUCTS. IF THESE THIRD PARTIES DO
NOT SUCCESSFULLY MANUFACTURE OUR PRODUCTS, OUR BUSINESS WILL BE HARMED.

         We have no experience in manufacturing products for clinical or
commercial purposes and do not have any manufacturing facilities. We intend to
continue to use third parties to manufacture our products for use in clinical
trials and for future sales. We may not be able to enter into future third-party
contract manufacturing agreements on acceptable terms, if at all.

         Contract manufacturers often encounter difficulties in scaling up
production, including problems involving production yields, quality control and
assurance, shortage of qualified personnel, compliance with FDA and foreign
regulations, production costs and development of advanced manufacturing
techniques and process controls. Our third-party manufacturers may not perform
as agreed or may not remain in the contract manufacturing business for the time
required by us to successfully produce and market our drug candidates. In
addition, our contract manufacturers will be subject to ongoing periodic,
unannounced inspections by the FDA and corresponding foreign governmental
agencies to ensure strict compliance with, among other things, current good
manufacturing practices, in addition to other governmental regulations and
corresponding foreign standards. We will not have control over, other than by
contract, third-party manufacturers' compliance with these regulations and
standards. Switching or engaging multiple manufacturers may be difficult because
the number of potential manufacturers is limited and, particularly in the case
of KRX-101, the process by which multiple manufacturers make the drug substance
must be identical at each manufacturing facility. It may be difficult for us to
find and engage replacement or multiple manufacturers quickly and on terms
acceptable to us, if at all. Moreover, if we need to change manufacturers, the
FDA and corresponding foreign regulatory agencies must approve these
manufacturers in advance, which will involve testing and additional inspections
to ensure compliance with FDA and foreign regulations and standards.

         If third-party manufacturers fail to deliver the required quantities of
our drug candidates on a timely basis and at commercially reasonable prices, and
if we fail to find replacement or multiple manufacturers on acceptable terms,
our ability to develop and deliver products on a timely and competitive basis
may be adversely impacted and our business, financial condition or results of
operations will be materially harmed.

         In the event that we are unable to obtain or retain third-party
manufacturers, we will not be able to commercialize our products as planned. The
manufacture of our products for clinical trials and commercial



                                       5


purposes is subject to FDA and foreign regulations. No assurance can be given
that our third-party manufacturers will comply with these regulations or other
regulatory requirements now or in the future.

         We recently entered into a contract manufacturing relationship with a
U.S.-based contract manufacturer for KRX-101 which we believe will be adequate
to satisfy our current clinical and commercial supply needs. However, as we seek
to transition our manufacturing of KRX-101 to our new contract manufacturer, we
will need to create a reproducible manufacturing process that will ensure
consistent manufacture of KRX-101 across multiple batches and sources. As with
all heparin-like compounds, the end product is highly sensitive to the
manufacturing process utilized. Accordingly, the creation of a reproducible
process will be required for the successful commercialization of KRX-101. There
can be no assurance that we will be successful in this endeavor.

IF WE ARE NOT ABLE TO OBTAIN THE RAW MATERIAL REQUIRED FOR THE MANUFACTURE OF
OUR LEAD PRODUCT CANDIDATE, KRX-101, OUR ABILITY TO DEVELOP AND MARKET THIS
PRODUCT CANDIDATE WILL BE SUBSTANTIALLY HARMED.

         Source materials for KRX-101, our lead product candidate, are derived
from porcine intestines. Long-term supplies for KRX-101 could be affected by
limitations in the supply of porcine intestines and the demand for other heparin
products, over which we will have no control. Additionally, diseases affecting
the world supply of pigs could have an actual or perceived negative impact on
our ability, or the ability of our contract manufacturers, to source, make
and/or sell KRX-101. Such negative impact could materially adversely affect the
commercial success of KRX-101.

IF OUR COMPETITORS DEVELOP AND MARKET PRODUCTS THAT ARE LESS EXPENSIVE, MORE
EFFECTIVE OR SAFER THAN OUR PRODUCT CANDIDATES, OUR COMMERCIAL OPPORTUNITY MAY
BE REDUCED OR ELIMINATED.

         The pharmaceutical industry is highly competitive. Our commercial
opportunity may be reduced or eliminated if our competitors develop and market
products that are less expensive, more effective or safer than our drug
candidates. Other companies have products or drug candidates in various stages
of pre-clinical or clinical development to treat diseases for which we are also
seeking to discover and develop drug candidates. Some of these potential
competing drugs are further advanced in development than our drug candidates and
may be commercialized earlier. Even if we are successful in developing effective
drugs, our products may not compete successfully with products produced by our
competitors.

         Our competitors include pharmaceutical companies and biotechnology
companies, as well as universities and public and private research institutions.
In addition, companies that are active in different but related fields represent
substantial competition for us. Many of our competitors have significantly
greater capital resources, larger research and development staffs and facilities
and greater experience in drug development, regulation, manufacturing and
marketing than we do. These organizations also compete with us to recruit
qualified personnel, attract partners for joint ventures or other
collaborations, and license technologies that are competitive with ours. As a
result, our competitors may be able to more easily develop technologies and
products that could render our technologies or our drug candidates obsolete or
noncompetitive.

IF WE LOSE OUR KEY PERSONNEL OR ARE UNABLE TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL, OUR OPERATIONS COULD BE DISRUPTED AND OUR BUSINESS COULD BE HARMED.

         We currently have 18 full and part-time employees. To successfully
develop our drug candidates, we must be able to attract and retain highly
skilled personnel. In addition, if we lose the services of our current
personnel, in particular, Michael S. Weiss, our Chairman and Chief Executive
Officer, our ability to continue to execute our business plan could be
materially impaired. In addition, while we have an employment agreement with Mr.
Weiss, this agreement would not prevent him from terminating his employment with
us.

ANY ACQUISITIONS WE MAKE MAY NOT BE SCIENTIFICALLY OR COMMERCIALLY SUCCESSFUL.

         As part of our business strategy, we may effect acquisitions to obtain
additional businesses, products, technologies, capabilities and personnel. If we
make one or more significant acquisitions in which the consideration includes
stock or other securities, your equity in us may be significantly diluted. If we
make one or more significant acquisitions in which the consideration includes
cash, we may be required to use a substantial portion of our available cash.



                                       6


         Acquisitions involve a number of operational risks, including:

         o    difficulty and expense of assimilating the operations, technology
              and personnel of the acquired business;

         o    inability to retain the management, key personnel and other
              employees of the acquired business;

         o    inability to maintain the acquired company's relationship with key
              third parties, such as alliance partners;

         o    exposure to legal claims for activities of the acquired business
              prior to acquisition;

         o    diversion of management attention; and

         o    potential impairment of substantial goodwill and write-off of
              in-process research and development costs, adversely affecting our
              reported results of operations.

WE FACE PRODUCT LIABILITY RISKS AND MAY NOT BE ABLE TO OBTAIN ADEQUATE
INSURANCE.

         The use of our drug candidates in clinical trials, and the sale of any
approved products, exposes us to liability claims. Although we are not aware of
any historical or anticipated product liability claims against us, if we cannot
successfully defend ourselves against product liability claims, we may incur
substantial liabilities or be required to cease clinical trials of our drug
candidates or limit commercialization of any approved products.

         We believe that we have obtained reasonably adequate product liability
insurance coverage for our clinical trials. We intend to expand our insurance
coverage to include the commercial sale of any approved products if marketing
approval is obtained. However, insurance coverage is becoming increasingly
expensive. We may not be able to maintain insurance coverage at a reasonable
cost. We may not be able to obtain additional insurance coverage that will be
adequate to cover product liability risks that may arise. Regardless of merit or
eventual outcome, product liability claims may result in:

         o    decreased demand for a product;

         o    injury to our reputation;

         o    inability to continue to develop a drug candidate;

         o    withdrawal of clinical trial volunteers; and

         o    loss of revenues.

         Consequently, a product liability claim or product recall may result in
losses that could be material.

IN CONNECTION WITH PROVIDING OUR SERVICES, WE MAY BE EXPOSED TO LIABILITY THAT
COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR FINANCIAL CONDITION AND RESULTS OF
OPERATIONS.

         In conducting the activities of OCOG, any failure on our part to comply
with applicable governmental regulations or contractual obligations could expose
us to liability to our clients and could have a material adverse effect on us.
We also could be held liable for errors or omissions in connection with the
services we perform. In addition, the wrongful or erroneous delivery of health
care information or services may expose us to liability. We could be materially
and adversely affected if we are required to pay damages or bear the costs of
defending any such claims.

RISKS RELATED TO OUR FINANCIAL CONDITION

IF WE ARE UNABLE TO OBTAIN ADDITIONAL FUNDS ON TERMS FAVORABLE TO US, OR AT ALL,
OUR BUSINESS WOULD BE HARMED.

         We expect to use rather than generate funds from operations for the
foreseeable future. Based on our current plans, we believe our existing cash and
cash equivalents will be sufficient to fund our operating expenses and capital
requirements for at least the next 36 months. However, the actual amount of
funds that we will need prior to or after that



                                       7


date will be determined by many factors, some of which are beyond our control.
As a result, we may need funds sooner or in different amounts than we currently
anticipate. These factors include:

         o    the progress of our development activities;

         o    the progress of our research activities;

         o    the number and scope of our development programs;

         o    our ability to establish and maintain current and new licensing or
              acquisition arrangements;

         o    our ability to achieve our milestones under our licensing
              arrangements;

         o    the costs involved in enforcing patent claims and other
              intellectual property rights; and

         o    the costs and timing of regulatory approvals.

If our capital resources are insufficient to meet future capital requirements,
we will have to raise additional funds. If we are unable to obtain additional
funds on terms favorable to us or at all, we may be required to cease or reduce
our operating activities or sell or license to third parties some or all of our
technology. If we raise additional funds by selling additional shares of our
capital stock, the ownership interests of our stockholders will be diluted. If
we raise additional funds through the sale or license of our technology, we may
be unable to do so on terms favorable to us.

RISKS RELATED TO OUR INTELLECTUAL PROPERTY

IF WE ARE UNABLE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY, THIRD PARTIES
MAY BE ABLE TO USE OUR TECHNOLOGY, WHICH COULD ADVERSELY AFFECT OUR ABILITY TO
COMPETE IN THE MARKET.

         Our commercial success will depend in part on our ability and the
ability of our licensors to obtain and maintain patent protection on our drug
products and technologies and successfully defend these patents and technologies
against third-party challenges. The patent positions of pharmaceutical and
biotechnology companies can be highly uncertain and involve complex legal and
factual questions. No consistent policy regarding the breadth of claims allowed
in biotechnology patents has emerged to date. Accordingly, the patents we use
may not be sufficiently broad to prevent others from practicing our technologies
or from developing competing products. Furthermore, others may independently
develop similar or alternative technologies or design around our patented
technologies. The patents we use may be challenged or invalidated or may fail to
provide us with any competitive advantage.

         Moreover, we rely on trade secrets to protect technology where we
believe patent protection is not appropriate or obtainable. However, trade
secrets are difficult to protect. While we require our employees, collaborators
and consultants to enter into confidentiality agreements, this may not be
sufficient to adequately protect our trade secrets or other proprietary
information. In addition, we share ownership and publication rights to data
relating to some of our drug candidates with our research collaborators and
scientific advisors. If we cannot maintain the confidentiality of this
information, our ability to receive patent protection or protect our proprietary
information will be at risk.

LITIGATION OR THIRD-PARTY CLAIMS OF INTELLECTUAL PROPERTY INFRINGEMENT COULD
REQUIRE US TO SPEND SUBSTANTIAL TIME AND MONEY DEFENDING SUCH CLAIMS AND
ADVERSELY AFFECT OUR ABILITY TO DEVELOP AND COMMERCIALIZE OUR PRODUCTS.

         Third parties may assert that we are using their proprietary technology
without authorization. In addition, third parties may have or obtain patents in
the future and claim that our technologies infringe their patents. If we are
required to defend against patent suits brought by third parties, or if we sue
third parties to protect our patent rights, we may be required to pay
substantial litigation costs, and our management's attention may be diverted
from operating our business. In addition, any legal action against our licensors
or us that seeks damages or an injunction of our commercial activities relating
to the affected technologies could subject us to monetary liability and require
our licensors or us to obtain a license to continue to use the affected
technologies. We cannot predict whether our licensors or we would prevail in any
of these types of actions or that any required license would be made available
on commercially acceptable terms, if at all.

RISKS RELATED TO OUR COMMON STOCK

CONCENTRATION OF OWNERSHIP OF OUR COMMON STOCK AMONG OUR EXISTING EXECUTIVE
OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS MAY PREVENT NEW INVESTORS FROM
INFLUENCING SIGNIFICANT CORPORATE DECISIONS.

         As of December 31, 2003, our executive officers, directors and
principal stockholders (including their affiliates) beneficially own, in the
aggregate, approximately 23.85% of our outstanding common stock, including, for
this purpose, currently exercisable options and warrants held by our executive
officers, directors and principal stockholders. As a result, these persons,
acting together, may have the ability to effectively determine the outcome of
all matters submitted to our stockholders for approval, including the election
and removal of directors and any merger, consolidation or sale of all or
substantially all of our assets. In addition, such persons, acting together, may
have the ability to effectively control our management and affairs. Accordingly,
this concentration of ownership may harm the market price of our common stock by
discouraging a potential acquirer from attempting to acquire us.

OUR STOCK PRICE COULD BE VOLATILE AND YOUR INVESTMENT COULD DECLINE IN VALUE.

         The trading price of our common stock is likely to be highly volatile
and subject to wide fluctuations in price in response to various factors, many
of which are beyond our control. These factors include:

         o    developments concerning our drug candidates;

         o    announcements of technological innovations by us or our
              competitors;

         o    introductions or announcements of new products by us or our
              competitors;

         o    announcements by us of significant acquisitions, strategic
              partnerships, joint ventures or capital commitments;

         o    changes in financial estimates by securities analysts;

         o    actual or anticipated variations in quarterly operating results;

         o    expiration or termination of licenses, research contracts or other
              collaboration agreements;

         o    conditions or trends in the regulatory climate and the
              biotechnology and pharmaceutical industries;

         o    changes in the market valuations of similar companies; and

         o    additions or departures of key personnel.

In addition, equity markets in general, and the market for biotechnology and
life sciences companies in particular, have experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating
performance of companies traded in those markets. These broad market and
industry factors may materially affect the market price of our common stock,
regardless of our development and operating performance. In the past, following
periods of volatility in the market price of a company's securities, securities
class-action litigation has often been instituted against that company. Such
litigation, if instituted against us, could cause us to incur substantial costs
to defend such claims and divert management's attention and resources, which
could seriously harm our business.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD MAKE A
THIRD-PARTY ACQUISITION OF US DIFFICULT. THIS COULD LIMIT THE PRICE INVESTORS
MIGHT BE WILLING TO PAY IN THE FUTURE FOR OUR COMMON STOCK.

         Provisions in our amended and restated certificate of incorporation and
bylaws could have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from attempting to acquire, or control
us. These provisions could limit the price that certain investors might be
willing to pay in the future for shares of our common stock. Our amended and
restated certificate of incorporation allows us to issue preferred stock with
rights senior to those of the common stock without any further vote or action by
the stockholders and our amended and restated bylaws eliminate the right of
stockholders to call a special meeting of stockholders, which



                                       9


could make it more difficult for stockholders to effect certain corporate
actions. These provisions could also have the effect of delaying or preventing a
change in control. The issuance of preferred stock could decrease the amount of
earnings and assets available for distribution to the holders of our common
stock or could adversely affect the rights and powers, including voting rights,
of such holders. In certain circumstances, such issuance could have the effect
of decreasing the market price of our common stock.

                           FORWARD LOOKING STATEMENTS

         When used in this prospectus and elsewhere by management or us from
time to time, the words "anticipate," "believe," "estimate," "may," "expect" and
similar expressions are generally intended to identify forward-looking
statements. These forward-looking statements include, but are not limited to,
statements about our:

         o    expectations for increases or decreases in expenses;

         o    expectations for the development, manufacturing, and approval of
              KRX-101, KRX-0401, KRX-0402, KRX-0403 or any other products we may
              acquire or in-license;

         o    expectations for incurring additional capital expenditures to
              expand our research and development capabilities;

         o    expectations for generating revenue or becoming profitable on a
              sustained basis;

         o    ability to enter into marketing and other partnership agreements;

         o    ability to enter into product acquisition and in-licensing
              transactions;

         o    estimates of the sufficiency of our existing cash and cash
              equivalents and investments to finance our operating and capital
              requirements;

         o    expected losses; and

         o    expectations for future capital requirements.

         Our actual results could differ materially from those results expressed
in, or implied by, these forward-looking statements. Potential risks and
uncertainties that could affect our actual results include those discussed in
this prospectus under the heading "Risk Factors." Such risks and uncertainties
also include the possibility that we may fail to establish and correctly apply
our critical accounting policies and estimates to our financial statements. The
list of factors that may affect future performance and the accuracy of
forward-looking statements is illustrative, but by no means exhaustive.

         Accordingly, all forward-looking statements should be evaluated with
the understanding of their inherent uncertainty.

         Although we believe that the expectations reflected in the
forward-looking statements are reasonable, we cannot guarantee future results,
events, levels of activity, performance or achievements. We do not assume
responsibility for the accuracy and completeness of the forward-looking
statements.

         We do not intend to update any of the forward-looking statements after
the date of this prospectus to conform them to actual results.

                                 USE OF PROCEEDS

         We will not receive any proceeds from the sale of the shares of common
stock by the selling stockholders. All net proceeds from the sale of shares of
common stock covered by this prospectus will go to the selling stockholders upon
the offer and sale of their shares. See "Selling Stockholders" and "Plan of
Distribution" described below.

                              SELLING STOCKHOLDERS

         We issued shares of our common stock pursuant to a merger agreement
that closed on February 5, 2004. Selling stockholders, including any non-sale
transferees, pledgees, donees, assignees or their successors-in-interest, may
from time to time offer and sell any or all of the common stock pursuant to this
prospectus. Because the selling stockholders may offer all or some portion of
the common stock, no estimate can be given as to the amount of the common stock
that will be held by the selling stockholders upon consummation or termination
of any sales.

         Information about the selling stockholders may change over time. Any
changed information given to us by the selling stockholders will be set forth in
prospectus supplements or amendments to this prospectus if and when necessary.
The table below sets forth information as of April 1, 2004 with respect to the
number of shares of common stock beneficially owned by each of the selling
stockholders and the number of shares being offered for sale by each selling
stockholder.

                              PLAN OF DISTRIBUTION

         The selling stockholders and any of their transferees, pledgees,
donees, assignees and successors-in-interest may, from time to time, sell any or
all of their shares of common stock on any stock exchange, market or trading
facility on which the shares are then listed, admitted to unlisted trading
privileges or included for quotation or in private transactions. These sales may
be at fixed or negotiated prices. The selling stockholders may use any one or
more of the following methods when selling shares:

         o    ordinary brokerage transactions and transactions in which the
              broker-dealer solicits purchasers;

         o    one or more block trades in which the broker-dealer will attempt
              to sell the shares as agent but may position and resell a portion
              of the block as principal to facilitate the transaction;



                                       13


         o    purchases by a broker-dealer as principal and resale by the
              broker-dealer for its account;

         o    an exchange distribution in accordance with the rules of the
              applicable exchange;

         o    privately negotiated transactions;

         o    settlement of short sales created after the date of the private
              placement;

         o    broker-dealers may agree with the selling stockholders to sell a
              specified number of such shares at a stipulated price per share;

         o    a combination of any such methods of sale; and

         o    any other method permitted pursuant to applicable law.

         The selling stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

         Broker-dealers engaged by the selling stockholders may arrange for
other broker-dealers to participate in sales. Broker-dealers may receive
commissions, discounts or concessions from the selling stockholders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated. The selling stockholders do not expect these
commissions and discounts to exceed what is customary in the types of
transactions involved.

         The selling stockholders may from time to time pledge or grant a
security interest in some or all of the shares of common stock or warrants owned
by them and, if they default in the performance of their secured obligations,
the pledgees or secured parties may offer and sell the shares of common stock
from time to time under this prospectus, or under an amendment to this
prospectus under the applicable provision of the Securities Act of 1933 amending
the list of selling stockholders to include the transferees, pledgees, donees,
assignees and successors-in-interest as selling stockholders under this
prospectus.

         The selling stockholders also may transfer the shares of common stock
in other circumstances, in which case the transferees, pledgees, donees,
assignees and successors-in-interest will be the selling beneficial owners for
purposes of this prospectus.

         The selling stockholders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. The selling stockholders have
informed us that none of them has any agreement or understanding, directly or
indirectly, with any person to distribute the common stock.

         We are required to pay all fees and expenses that we incur incident to
the registration of the shares. We have agreed to indemnify the selling
stockholders, with respect to this registration statement, against certain
losses, claims, damages and liabilities, including liabilities under the
Securities Act.

         The anti-manipulation rules under the Exchange Act may apply to sales
of the shares of common stock in the market and to the activities of the selling
stockholders and their affiliates.

         We have agreed to use our best efforts to keep this registration
statement continuously effective under the Securities Act until the date which
is two years after the date that this registration statement is declared
effective by the Securities and Exchange Commission or such earlier date when
all shares of the common stock covered by this registration statement has been
sold or may be sold without volume restrictions pursuant to Rule 144(k) as
determined by our counsel pursuant to a written opinion letter to such effect,
addressed and acceptable to our transfer agent and the affected selling
stockholders.

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

         The table below itemizes the expenses payable by the Registrant in
connection with the registration and issuance of the securities being registered
hereunder, other than underwriting discounts and commissions. All amounts except
the Securities and Exchange Commission registration fee are estimated.

Securities and Exchange Commission Registration Fee ................    $ 1,232

Legal Fees and Expenses ............................................     10,000

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


         Under the General Corporation Law of the State of Delaware, or DGCL, a
corporation may include provisions in its certificate of incorporation that will
relieve its directors of monetary liability for breaches of their fiduciary duty
to the corporation, except under certain circumstances, including a breach of
the director's duty of loyalty, acts or omissions of the director not in good
faith or which involve intentional misconduct or a knowing violation of law, the
approval of an improper payment of a dividend or an improper purchase by the
corporation of stock or any transaction from which the director derived an
improper personal benefit. The Registrant's Amended and Restated Certificate of
Incorporation, as amended, eliminates the personal liability of directors to the
Registrant or its stockholders for monetary damages for breach of fiduciary duty
as a director with certain limited exceptions set forth in the DGCL.

         Section 145 of the DGCL grants to corporations the power to indemnify
each officer and director against liabilities and expenses incurred by reason of
the fact that he or she is or was an officer or director of the corporation if
he or she acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the corporation and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his or
her conduct was unlawful. The Registrant's Amended and Restated Certificate of
Incorporation, as amended, and Amended and Restated Bylaws provide for
indemnification of each officer and director of the Registrant to the fullest
extent permitted by the DGCL. Section 145 of the DGCL also empowers corporations
to purchase and maintain insurance on behalf of any person who is or was an
officer or director of the corporation against liability asserted against or
incurred by him in any such capacity, whether or not the corporation would have
the power to indemnify such officer or director against such liability under the
provisions of Section 145 of the DGCL.

ITEM 17.     UNDERTAKINGS.

(a) The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

              (i) To include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933;

              (ii) To reflect in the prospectus any facts or events arising
         after the effective date of the registration statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the registration statement. Notwithstanding the foregoing, any
         increase or decrease in the volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b)) if, in the aggregate, the
         changes in volume and price represent no more than 20% change in the
         maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective registration statement; and

              (iii) To include any material information with respect to the plan
         of distribution not previously disclosed in the registration statement
         or any material change to such information in the registration
         statement;

         provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above shall
         not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed with or furnished to the Commission by the registrant
         pursuant to Section 13 or Section 15(d) of the Securities Exchange Act
         of 1934 that are incorporated by reference in the registration
         statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be initial bona fide
offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.



                                      II-2


(h) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.



                                      II-3


                                   SIGNATURES

the registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and has duly caused this
registration statement to be signed on its behalf by the undersigned, thereunto
duly authorized in the City of New York, State of New York, on April 19, 2004.
