GeoVax Achieves Milestone in Transition to Commercially Validated Manufacturing System

Manufacturing Process for Phase 3 and Commercial Production

Being Developed for GeoVax MVA-Based Vaccines


Atlanta, GA, March 6, 2024 – GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced a significant milestone toward implementation of a validated chicken embryonic fibroblast (CEF) based production system for the company’s MVA-based vaccines, with the release of its first lot of GEO-CM04S1 (next-generation Covid-19 vaccine) produced with a commercial manufacturing platform. This milestone marks the successful completion of the transfer and scale-up of manufacturing from the research-focused Center for Biomedicine & Genetics at City of Hope (Duarte, CA) to the experienced CDMO ABL Europe (a subsidiary of Oxford Biomedica), the Company’s cGMP (current Good Manufacturing Procedures) manufacturing partner.

David Dodd, GeoVax President and CEO, commented, “The successful establishment of cGMP production at ABL Europe represents great progress for GeoVax and the CM04S1 program. This latest manufacturing milestone also validates our choice of ABL Europe as our partner for cGMP production of our MVA-based vaccine candidates. This gives us a high degree of confidence in our manufacturing process as we move into late-stage clinical development for CM04S1, addressing a critically important unmet medical need for immunocompromised populations.”

Dodd continued, “While we continue the use of CEF-based production for our CM04S1 clinical programs, it is important to also recognize the significant advancements made in our commercial-scale production capabilities. Our multi-product license of ProBioGen’s AGE1.CR.PIX® suspension cell line enhances our capacity to produce MVA-based vaccines (including CM04S1 and GEO-MVA) and immunotherapies at an unprecedented scale. These developments signify GeoVax's commitment to improving vaccine accessibility through cost-effective and scalable manufacturing processes.”

About GEO-CM04S1

GEO-CM04S1 is a next-generation Covid-19 vaccine based on GeoVax’s MVA viral vector platform, which supports the presentation of multiple vaccine antigens to the immune system in a single dose. CM04S1 presents both the spike and nucleocapsid antigens of SARS-CoV-2 and is specifically designed to induce both antibody and T cell responses to non-variable parts of the virus. The more broadly specific and functional engagement of the immune system is designed to protect against the continually emerging variants of Covid-19. Results released during 2023 demonstrated the safety and efficacy of CM04S1 and emphasize the role it will play in protecting immunocompromised patients from greater risk of severe disease, hospitalization and death from SARS-CoV-2 infection.


In response to the global need to address the continued emerging threat from Mpox (monkeypox), GeoVax previously announced having secured rights from the National Institutes of Health (NIH) covering preclinical, clinical and commercial uses of the NIH-MVA as a vaccine against Mpox or smallpox. The Company is currently pursuing different regulatory pathways toward achievement of an expedited approval and intends to become the first U.S.-based supplier of the MVA vaccine to prevent Mpox and smallpox.

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:
