Continued Progress on COVID-19 and Immuno-Oncology Programs

Atlanta, GA - (NewMediaWire) - August 11, 2021 - GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against infectious diseases and cancers, today announced its financial results for the quarter ended June 30, 2021.

GeoVax’s management will host a live conference call and webcast at 4:30 p.m. Eastern Standard Time on Wednesday, August 11 to discuss financial results and provide a general business update. Details are provided below.  

2021 YTD Highlights and Development Program Status Update

COVID-19 Vaccine – GeoVax’s SARS-CoV-2 (COVID-19) vaccine is based on its GV-MVA-VLPTM technology, which enables insertion of multiple antigen fragments, potentially allowing for broad-spectrum virus prevention. Unlike other vaccines that target only the COVID-19 spike protein, the Company’s vaccines are designed to provoke a response to multiple COVID-19 antigens, which means they could be less susceptible to viral mutations. The Company’s vaccines are intended to be used as either a primary vaccine or to boost other COVID-19 vaccines as part of vaccination strategies to provide immunity to a range of coronavirus variants. GeoVax believes a critical and significant opportunity exists for a pan-coronavirus vaccine with the attributes the GV-MVA-VLP technology can offer.  

In January 2021, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), awarded GeoVax a Small Business Innovative Research (SBIR) grant for development of a COVID-19 vaccine.  The Phase 1 grant, titled, “Preclinical Development of GV-MVA-VLP Vaccines Against COVID-19,” supports the ongoing design, construction, and preclinical testing of GeoVax’s vaccine candidates in preparation for human clinical trials.

Small animal studies are continuing and results to date support the Company’s approach of using MVA as a vector for the design and production of  “next-generation” vaccines encoding multiple proteins. Details of the studies will be presented on August 19 during the European Society of Medicine (ESMED) General Assembly. Based on the encouraging results, the Company recently submitted an application to NIAID for additional support for advanced testing.

Cancer Immunotherapy – GeoVax’s cancer immunotherapy program is based on the concept of combining a tumor-associated antigen vaccine with a potent anti-tumor agent, such as an Immune Checkpoint Inhibitor (“ICI”), with the goal of achieving regression of tumor growth and development.  In February 2021, the Company filed a U.S. patent application, covering updates to its MVA viral vector technology to amplify an immune response to a cancer antigen via vaccination, which could strengthen the Company’s intellectual property position in this space. Immuno-oncology is an important focus area for the Company, and GeoVax is engaging with multiple collaborators. The initial animal studies, based upon a GeoVax-MUC1 vaccine/ICI combination, have been encouraging and additional studies are being planned with the goal of expanding the overall cancer immunotherapy program.  The Company expects to provide further details on its progress and plans to advance to human clinical testing in the near future.

Lassa Fever – Progress continues using grant funding from the U.S. Department of Defense for the Company’s Lassa Fever (LASV) vaccine program. The project award supports generation of immunogenicity and efficacy data for GeoVax’s vaccine candidate in both rodent and nonhuman primate models, as well as manufacturing process development and cGMP production of vaccine seed stock in preparation for human clinical trials. This work is in collaboration with U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) and the Geneva Foundation. Technical issues associated with the manufacturing process combined with the limited availability of nonhuman primates have resulted in delays to this program, but the work is advancing and results are now expected to be available in late 2021 or early 2022.

Sudan ebolavirus and Marburg virus – In July 2021, GeoVax announced results of preclinical efficacy studies of its Sudan ebolavirus (SUDV) vaccine candidate (MVA-VLP-SUDV). Immunogenicity and efficacy of MVA-VLP-SUDV were tested in a guinea pig lethal challenge model, in which asingle intramuscular dose of the GeoVax vaccine protected 100% of animals challenged with a lethal dose of SUDV. A comparison between prime and prime-boost vaccinations of guinea pigs showed that both regimens elicited SUDV-specific binding and neutralizing antibody responses, and that the second immunization enhanced these responses. Challenge of vaccinated animals with guinea pig-adapted SUDV demonstrated complete protection against death and disease by the prime and the prime-boost regimens. This is the first report that a replication-deficient MVA vector may confer full protection against SUDV after a single dose. This work was conducted in collaboration with researchers at the University of Texas Medical Branch (UTMB).

Separately, GeoVax is leading a multi-party collaboration for the development of its (SUDV) and Marburg virus (MARV) vaccine candidates. The collaboration, between GeoVax, researchers at UTMB and Battelle Memorial Institute, utilizes the suite of preclinical services from NIAID. Under the collaboration, GeoVax’s SUDV and MARV vaccine candidates are being tested for immunogenicity and efficacy in the benchmark nonhuman primate model. This work builds uponearlier studies in rodents and nonhuman primates for the Company’s Ebola virus (EBOV) vaccine candidate that demonstrated 100% protection against a lethal dose of EBOV following a single immunization. The Company expects to announce additional results during the second half of 2021.

Malaria Vaccine – Exploratory studies in collaboration with the Burnet Institute in Australia and Leidos, Inc. have been encouraging.We continue to evaluate advancing this program into formal product development since a Malaria vaccine is not currently a product development initiative.   

HIV Vaccine Programs – NIAID has funded multiple clinical trials of GeoVax’s HIV preventive vaccine (GOVX-B11) through the HIV Vaccine Trials Network (HVTN).  The next planned trial (HVTN 132) is designed to further evaluate the safety and immunogenicity of adding “protein boost” components to the GOVX-B11 vaccination regimen. The start of HVTN 132 has been delayed due to COVID-19, and the Company awaits further information from NIAID and HVTN on when the trial may commence. The Company is also part of efforts to develop a combination therapy to induce remission in HIV-positive individuals (a “functional cure”). In August 2020, a consortium led by researchers at the University of California, San Francisco (UCSF) began enrolling patients in a Phase 1 human clinical trial using our vaccine as part of a combination therapy intended to induce remission in HIV-positive individuals. Similar to HVTN 132, this trial has been affected by the pandemic, so we await further information regarding the status of patient enrollment and trial results.  Our prior collaboration with American Gene Technologies International, Inc. (AGT) was recently discontinued due to AGT’s remodeling of their clinical trial plans, but the Company remains open to additional collaborations.

Intellectual Property – In February 2021, GeoVax filed international and U.S. patent applications in our key focus areas of SARS-CoV-2 (COVID-19) and cancer immunotherapy, and in July 2021 the Company announced the issuance of a U.S. patent covering our Hepatitis B vaccine. Following these filings, GeoVax’s wholly owned, co-owned, and in-licensed intellectual property portfolio now stands at over 70 granted or pending patent applications spread over 20 patent families.

Management Commentary

David Dodd, GeoVax’s Chairman and CEO, commented, “We remain enthusiastic about our development programs and expect several data announcements in the forthcoming weeks and months, most notably in our program areas of COVID-19, Lassa Fever virus, Sudan/Marburg virus and immuno-oncology. As with many other companies, the continuing COVID-19 pandemic has affected the timelines for some of our programs, most notably our HIV program. In addition, third-party technical disruptions have resulted in delays in completing various contracted animal studies. I look forward to sharing news of our progress as those studies are completed and other events occur. We remain encouraged and focused on completing these studies as soon as possible and announcing the various results.

“With our funding events from 2020 and early 2021, we are well-positioned to advance several of our development programs, with a continued focus on our COVID-19 vaccine and our cancer immunotherapy programs. The additional capital is allowing us to make infrastructure and personnel investments, as well as funding commitments in support of other programs, including manufacturing process development with a view toward cost-effective, large-scale production for clinical and commercial distribution.  Our focus and goal is to advance into clinical development both within the areas of infectious diseases and immuno-oncology, providing significant potential growth in value for our shareholders while providing new vaccines and therapies for critical areas of health worldwide,” concluded Mr. Dodd.

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing human vaccines against infectious diseases and cancer using a novel patented Modified Vaccinia Ankara-Virus Like Particle (MVA-VLP) based vaccine platform. On this platform, MVA, a large virus capable of carrying several vaccine antigens, expresses proteins that assemble into VLP immunogens in the person receiving the vaccine. The production of VLPs in the person being vaccinated can mimic virus production in a natural infection, stimulating both the humoral and cellular arms of the immune system to recognize, prevent, and control the target infection. The MVA-VLP derived vaccines can elicit durable immune responses in the host similar to a live-attenuated virus, while providing the safety characteristics of a replication-defective vector. 

GeoVax’s current development programs are focused on preventive vaccines against COVID-19, Zika Virus, hemorrhagic fever viruses (Ebola, Sudan, Marburg, and Lassa), HIV, and malaria, as well as therapeutic vaccines against multiple cancers. The Company has designed a preventive HIV vaccine candidate to fight against the subtype of HIV prevalent in the commercial markets of the Americas, Western Europe, Japan, and Australia; human clinical trials for this program are managed by the HIV Vaccine Trials Network (HVTN) with the support of the National Institutes of Health (NIH). GeoVax’s HIV vaccine is also part a separate collaborative effort to apply its vaccine approach toward a functional cure for HIV.
