ATLANTA, GA, October 5, 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. 17/409,574 titled “Multivalent HIV Vaccine Boost Compositions and Methods of Use.” The allowed claims generally cover a priming vaccination with a DNA vector encoding multiple HIV antigens in virus-like particles (VLPs), followed by a boost vaccination with GeoVax’s vector platform for expressing HIV-1 antigens in VLPs utilizing an MVA viral vector.

David Dodd, GeoVax President and CEO, commented, “Our development priorities continue to be our next-generation COVID-19 vaccine, currently in Phase 2 clinical trials, and our cancer immunotherapy program, with Gedeptin^® as our lead product in a Phase 1/2 clinical trial for advanced head and neck cancer. While we are focusing on these two products in the near-term, our long-term vision includes developing vaccines against other global public health threats such as HIV. Although not currently under active development, our HIV program forms an important part of the dataset underpinning all of our MVA-based development programs. The patent protection associated with the use of this vaccine is an important part of this product platform.”

Mr. Dodd continued, “Earlier this year, data were presented from a clinical study of a combinational HIV therapy that included GeoVax’s HIV vaccine candidate, MVA62B. The goal of the trial was to reduce or eliminate viral replication in the absence of antiviral medications in HIV-positive individuals (a “functional cure”). The data indicated very high levels of immunogenicity of the treatment, particularly the induction of T cell immunity, even though HIV infection compromises the immune system. We are pleased that GeoVax’s MVA-vectored HIV vaccine was selected to be a part of the experimental combination therapy and contributed to the positive findings. MVA62B was also previously tested in multiple clinical trials as a component of vaccine regimens designed to induce immune responses that prevent HIV infection. The team here at GeoVax is committed to help end the HIV epidemic worldwide and recognizes that the consistent results of MVA62B reflected in clinical trials to date may offer promise towards achieving this goal. We remain committed to supporting corporate and/or academic collaborations or partnering of this potentially critically important vaccine.”

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel therapies and vaccines for solid tumor cancers and many of the world’s most threatening infectious diseases. The company’s 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. GeoVax’s 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: www.geovax.com.
