GeoVax Receives Notice of Allowance for Marburg Vaccine Patent

ATLANTA, GA - (NewMediaWire) - October 09, 2023 - GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced that the U.S. Patent and Trademark Office has issued a Notice of Allowance for Patent Application No. 17/584,231 titled Replication-Deficient Modified Vaccinia Ankara (MVA) Expressing Marburg Virus Glycoprotein (GP) and Matrix Protein (VP40).” The allowed claims generally cover GeoVaxs vector platform for expressing Marburg virus antigens in virus-like particles (VLPs) utilizing an MVA viral vector.

A recent presentation of data from nonhuman primate studies demonstrated that immunization with GeoVaxs vaccine candidate, GEO-MM01, conferred 80% survival in cynomolgus macaques following a lethal dose of Marburg virus. Vaccination protected from viremia, weight loss and death following challenge with a lethal Marburg virus dose. Evaluation of immune responses following vaccination demonstrated the presence of both neutralizing antibodies and functional T cells, indicating a breadth of responses that combine for optimal protection. GeoVax is currently evaluating study designs to assess the potential for administering different dose levels of the vaccine and different routes of vaccine delivery to optimize utility and efficacy.

David Dodd, GeoVax President and CEO, commented, While our focus and development priorities continue to be our next-generation COVID-19 vaccine and cancer immunotherapy programs, developing vaccines against lethal hemorrhagic fever viruses represents our commitment to addressing highly fatal endemic threats throughout the world. Our team is committed to supporting the successful advancement of such a vaccine, as we recognize the critically important medical and biodefense need, reflected by the inclusion of Marburg virus in the FDA Priority Review Voucher program. This patent allowance adds to our growing portfolio of wholly owned, co-owned, and in-licensed intellectual property, now standing at over 115 granted or pending patent applications spread over 24 patent families.”

About Marburg Virus

Marburg virus (MARV) is a hemorrhagic fever virus of the Filoviridae family, which also includes Ebola virus, and causes severe human disease with up to a 90% fatality rate. The Marburg virus is transmitted to people from fruit bats, and human-to-human transmission occurs through direct contact with bodily fluids, or contaminated surfaces and materials. MARV is rated by the World Health Organization (WHO) as a Risk Group 4 Pathogen. In the United States, the NIH/National Institute of Allergy and Infectious Diseases ranks it as a Category A Priority Pathogen and the Centers for Disease Control and Prevention lists it as a Category A Bioterrorism Agent. MARV typically appears in sporadic outbreaks throughout Africa and the virus continues to pose potential public health and biodefense threats. There are currently no licensed vaccines or therapeutics against the diseases caused by MARV.

About the GV-MVA-VLPTM Platform

GeoVaxs GV-MVA-VLPTM vaccine platform utilizes modified vaccinia Ankara (MVA), a large virus capable of carrying several vaccine antigens, that expresses proteins that assemble into virus-like particles (VLP) immunogens in the person receiving the vaccine. The production of VLPs in the person being vaccinated can mimic the virus production that occurs 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.

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel therapies and vaccines for solid tumor cancers and many of the worlds most threatening infectious diseases. The companys lead program in oncology is a novel oncolytic solid tumor gene-directed therapy, Gedeptin®, presently in a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. GeoVaxs lead infectious disease candidate is GEO-CM04S1, a next-generation COVID-19 vaccine targeting high-risk immunocompromised patient populations. Currently in three Phase 2 clinical trials, GEO-CM04S1 is being evaluated as a primary vaccine for immunocompromised patients such as those suffering from hematologic cancers and other patient populations for whom the current authorized COVID-19 vaccines are insufficient, and as a booster vaccine in patients with chronic lymphocytic leukemia (CLL). In addition, GEO-CM04S1 is in a Phase 2 clinical trial evaluating the vaccine as a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. GeoVax has a leadership team who have driven significant value creation across multiple life science companies over the past several decades. For more information, visit our website:
