GeoVax, Inc.: GeoVax Receives Notice of Allowance For Cancer Vaccine Patent

Adds to Growing Portfolio of Intellectual Property Assets

ATLANTA, Ga., Dec. 09, 2024 (GLOBE NEWSWIRE) -- 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. 17/876,682 to GeoVax, titled "Vaccinia Viral Vectors Encoding Chimeric Virus Like Particles." The allowed claims add to GeoVax's intellectual property protection related to its vector platform for expressing a tumor associated antigen (TAA) in virus-like particles (VLPs) from a recombinant Modified Vaccinia Ankara (MVA) viral vector, further demonstrating the GeoVax technical expertise.

The allowed claims encompass GeoVax's Mucin 1 (MUC1) tumor-associated antigen immunotherapy candidate, MVA-VLP-MUC1. The Company uses its MVA-VLP vaccine platform to express abnormal, aberrantly glycosylated forms of the cell surface-associated MUC1 protein that is associated with a wide range of cancers, including breast, colon, ovarian, prostate, pancreatic, and lung. In a therapeutic preclinical evaluation, MVA-VLP-MUC1 in combination with anti-PD-1 resulted in a 57% reduction in tumor growth compared to untreated controls. In a preventive ("tumor recurrence") model vaccination with MVA-VLP-MUC1 resulted in 100% prevention of tumor growth vs 100% tumor growth in the untreated cohort.

David Dodd, GeoVax President and CEO, commented, "This patent allowance adds to our growing portfolio of wholly owned, co-owned, and in-licensed intellectual property, now standing at over 120 granted or pending patent applications spread over 24 patent families. The initial results with our MVA-VLP-MUC1 immunotherapy candidates have been encouraging. We believe our MVA vector platform is well-suited for development of therapeutic cancer vaccines based on the expression of tumor-associated antigens such as MUC1 and Cyclin B1, among others."

Dodd added, "In addition to our work with MUC1, our lead program in oncology is the development of Gedeptin^®, a novel patented product for the treatment of solid tumors which recently completed a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. A Phase 2 clinical trial in first recurrent head and neck cancer, evaluating Gedeptin^® combined with an immune checkpoint inhibitor is planned to initiate during the first half 2025. We are excited by the potential for GeoVax's growing immuno-oncology pipeline and the opportunity to provide a broad array of therapies against solid tumors."

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing novel vaccines for many of the world's most threatening infectious diseases and therapies for solid tumor cancers. The company's lead clinical program is GEO-CM04S1, a next-generation COVID-19 vaccine for which GeoVax was recently awarded a BARDA-funded contract to sponsor a 10,000-participant Phase 2b clinical trial to evaluate the efficacy of GEO-CM04S1 versus an approved COVID-19 vaccine. In addition, GEO-CM04S1 is currently in three Phase 2 clinical trials, being evaluated as (1) 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, (2) a booster vaccine in patients with chronic lymphocytic leukemia (CLL) and (3) a more robust, durable COVID-19 booster among healthy patients who previously received the mRNA vaccines. In oncology the lead clinical program is evaluating a novel oncolytic solid tumor gene-directed therapy, Gedeptin®, having recently completed a multicenter Phase 1/2 clinical trial for advanced head and neck cancers. A Phase 2 clinical trial in first recurrent head and neck cancer, evaluating Gedeptin^® combined with an immune checkpoint inhibitor is planned to initiate during the first half of 2025. GeoVax has a strong IP portfolio in support of its technologies and product candidates, holding worldwide rights for its technologies and products. The Company has a leadership team who have driven significant value creation across multiple life science companies over the past several decades.
