The GeoVax Multi-antigenic MVA-VLP Approach Designed to Provide a Stronger, Broader Protection

Atlanta, GA, Dec. 14, 2021 (GLOBE NEWSWIRE) -- via NewMediaWire -- GeoVax Labs, Inc. (NASDAQ:GOVX), a biotechnology company developing human immunotherapies and vaccines against cancer and infectious diseases, today announced that the U.S. Patent and Trademark Office issued a Notice of Allowance for Patent Application No. 16/648,693 titled "Compositions and Methods for Generating an Immune Response to Treat or Prevent Malaria." In general, the claims to be granted in the patent cover GeoVax's modified vaccinia Ankara (MVA) vector expressing certain antigens from the malaria parasite.

Globally, malaria causes 228 million infections and 405,000 deaths annually. Despite decades of vaccine research, vaccine candidates have failed to induce substantial protection (e.g. >50%). Most of these vaccines are based on individual proteins that induce immune responses targeting only one stage of the malaria parasite's life cycle. GeoVax's MVA-VLP malaria vaccine candidates incorporate antigens derived from multiple stages of the parasite's life cycle and are designed to induce an immune response with durable functional antibodies and CD4+ and CD8+ T cell responses, all hallmarks of an ideal vaccine-induced immune response.

David Dodd, GeoVax President and CEO, commented, "Our corporate focus and development priorities continue to be our 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 Head and Neck cancer. However, developing vaccines against global public health threats, such as malaria, is also part of our longer-term focus. We remain strongly committed to advancing innovation towards improving public health worldwide and this patent reflects a potential game-changing advance relative to malaria prevention."

Mark Newman, PhD, GeoVax Chief Scientific Officer, commented, "We welcome the recognition of the inventiveness associated with our MVA-VLP vaccine platform. Collaborations with government institutions, such as the National Institutes of Health and USAID, and academic, such as the Burnet Institute, will continue to be components of our efforts to design, produce and test novel vaccines against malaria."

About the GV-MVA-VLP^TM Platform

GeoVax's GV-MVA-VLP^TM 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.
