GeoVax Receives BARDA Project NextGen Award to Conduct Phase 2b Clinical Study Evaluating the Company’s Next-Generation COVID-19 Vaccine Candidate, GEO-CM04S1

10,000-participant randomized Phase 2b study will evaluate and compare GeoVax’s multi-antigen, vaccine candidate (GEO-CM04S1) to an approved vaccine against COVID-19 under BARDA’s Clinical Studies Network

Atlanta, GA, June 18, 2024 – GeoVax Labs, Inc. (Nasdaq: GOVX), a biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today announced that it received an award through the Rapid Response Partnership Vehicle (RRPV) to advance development of GEO-CM04S1, GeoVax’s dual-antigen next-generation COVID-19 vaccine, in a Phase 2b clinical trial. The RRPV is a Consortium funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) in the U.S. Department of Health and Human Services (HHS).


Under the agreement, GeoVax will sponsor a 10,000-participant, randomized, Phase 2b double-blinded study to compare the efficacy, safety, and immunogenicity of GEO-CM04S1 with a U.S. Food and Drug Administration (FDA)-approved mRNA COVID-19 vaccine. Preparations for the study are underway, and execution of the study will be fully funded by BARDA under its Clinical Studies Network.


The direct award to GeoVax of approximately $24.3 million, which may increase to as much as $45 million, will fund the manufacturing of clinical materials and support for the Phase 2b clinical trial, including regulatory activities. BARDA has made separate awards through its Clinical Studies Network to support execution of the study. That funding will represent approximately $343M from the Project NextGen program for a CRO to execute the clinical trial using GeoVax’s vaccine.


“We are honored and proud to receive this award from BARDA to advance our next-generation vaccine against COVID-19. This contract not only provides the vital resources for advancing the development of GEO-CM04S1, but it also advances our MVA platform in infectious diseases,” said David Dodd, Chairman & CEO of GeoVax.


Mr. Dodd continued, “First-generation COVID-19 vaccines were beneficial during the peak of the pandemic but are limited in breadth and durability of clinical protection, requiring frequent updates. Now that COVID-19 is in an endemic stage, many people continue to have their everyday lives impacted in meaningful ways. Furthermore, there are an estimated 23 million adults in the U.S. with immunocompromised conditions who are less likely to have an adequate response to current vaccines and are more likely to potentially experience severe COVID-19 symptoms, hospitalization and the risk of death, even after vaccination. GEO-CM04S1 was designed to address these limitations by inducing durable neutralizing antibody and T-cell-based immunity against current and future SARS-CoV-2 variants. Our vaccine has continued to demonstrate induction of potent immune responses with potential to drive broad and durable clinical protection, and we eagerly anticipate commencing the Phase 2b study to further demonstrate the value and advantages of our technology.”


Funding for this award is provided under Project NextGen, a $5 billion initiative by HHS to advance a pipeline of new, innovative vaccines and therapeutics providing broader and more durable protection for COVID-19 than the first generation COVID vaccines and medicines. BARDA is supporting the development of new vaccines and therapeutics to better address the waning immunity and resistance to current and future SARS-CoV2 viral strains. GeoVax’s vaccine candidate provides many of the features identified by BARDA including broader protection among variants of concern (VOC) and a longer duration of protection.


This project is being funded with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response (ASPR); Biomedical Advanced Research and Development Authority (BARDA), under Other Transaction (OT) number: 75A50123D00005.


About GEO-CM04S1

GEO-CM04S1 is based on GeoVax’s MVA viral vector platform, which supports the presentation of multiple vaccine antigens to the immune system in a single dose. GEO-CM04S1 encodes for both the spike (S) and nucleocapsid (N) antigens of SARS-CoV-2 and is specifically designed to induce both antibody and T-cell responses to those parts of the virus less likely to mutate over time. The more broadly functional engagement of the immune system is designed to protect against severe disease caused by continually emerging variants of COVID-19. Vaccines of this format should not require frequent and repeated modification or updating.


GEO-CM04S1 is currently being evaluated in three ongoing Phase 2 clinical trials:

  • As a primary vaccine in immunocompromised patients (with hematologic cancers receiving cell transplants or CAR-T therapy). ClinicalTrials.gov Identifier: NCT04977024. A recent presentation of unpublished data from the open-label portion of the trial indicates that GEO-CM04S1 is highly immunogenic in these patients, inducing both antibody responses, including neutralizing antibodies, and T-cell responses.
  • As a booster vaccine in immunocompromised patients with chronic lymphocytic leukemia (CLL), a recognized high-risk group for whom current mRNA vaccines and monoclonal antibody (MAb) therapies appear inadequate relative to providing protective immunity. ClinicalTrials.gov Identifier: NCT05672355.
  • As a booster vaccine for healthy adults who have previously received the Pfizer or Moderna mRNA vaccine. gov Identifier: NCT04639466.

BIO Statement on the Section 232 Pharmaceutical Proclamation

April 4, 2026
April 2, 2026- WASHINGTON, D.C. – John F. Crowley, President and CEO of the Biotechnology Innovation Organization (BIO) , released the following statement on Section 232 Pharmaceutical Proclamation. “A thriving American biotechnology ecosystem is essential to growing the U.S. economy, strengthening national security, and improving the health and well‑being of everyday Americans. While we appreciate the Administration’s recognition of the need for tariff exemptions for certain critical biotech products, the reality is that any tariffs on America’s medicines will raise costs, impede domestic manufacturing, and delay the development of new treatments - all while doing nothing to enhance our national security. “U.S. biotech companies have been eager to expand investments here at home, but tariffs, along with an uncertain policy environment and efforts to force “most‑favored nation” schemes, work directly against that goal. The risks are especially acute for small and mid‑size biotech companies, which develop more than half of all FDA‑approved medicines yet often lack the capital to build dedicated manufacturing facilities as they weather an industry defined by high costs, long development timelines, and significant risk. “The fact is: tariffs divert scarce resources away from research and development, weaken American biotech against China’s rising industry, and ultimately, harm health and economic wellbeing of Americans. “We stand ready to work with the Administration on a long‑term strategy that encourages biotechnology investment, reduces the time, cost, and uncertainty of developing new medicines, expands U.S. biomanufacturing capacity, and ensures American innovation is fairly valued overseas. Tariffs and MFN are not the answer." Source - https://www.bio.org/press-release/bio-statement-section-232-pharmaceutical-proclamation

Georgia Life Sciences Announces 2026 Georgia BioGENEius Challenge Winner

April 1, 2026
Atlanta, GA (April 1, 2026) – Georgia Life Sciences (GLS) is proud to announce that Saisurya Lakkimsetti, a junior at Lakeside High School in Columbia County, has been named the winner of the 2026 Georgia BioGENEius Challenge. The Georgia BioGENEius Challenge took place, as part of the statewide Georgia Science and Engineering Fair (GSEF) at the Classic Center in Athens, Georgia. Forty-seven students from across Georgia competed for this year’s title and cash prize. Jaehyeon Lee, an 11th-grade student from Walton High School, was named runner-up in this year’s competition. The Georgia BioGENEius Challenge recognizes outstanding high school students who are conducting innovative biotechnology research with real-world applications. This year’s top projects, presented in the Global Healthcare Challenge track, demonstrated exceptional scientific rigor and forward-thinking potential in addressing critical healthcare challenges. Saisurya’s research focuses on identifying potential inhibitors for Endocan, a protein known to play a role in glioblastoma tumor growth. Using advanced computational modeling techniques—including AlphaFold and molecular docking tools—she screened thousands of small molecules to identify compounds that may block tumor-promoting signaling pathways. Her work identified several promising candidates that could serve as a foundation for future drug development targeting glioblastoma. Jaehyeon’s project investigates how varying glucose concentrations affect regeneration in planaria, modeling impaired wound healing in diabetic conditions. By testing graded glucose environments and measuring regeneration indicators such as growth and differentiation, Jaehyeon demonstrated that lower glucose levels enhance regeneration while higher levels inhibit healing. The study establishes a model to better understand hyperglycemia’s impact on diabetic wound healing. “The work by these students is a powerful example of the innovation and determination we see in Georgia’s next generation of life sciences leaders,” said Maria Thacker Goethe, President and CEO of Georgia Life Sciences. “The BioGENEius Challenge is critical because it provides students with a platform to apply cutting-edge science to real-world problems, while also strengthening the future workforce that will drive breakthroughs in healthcare, biotechnology, and beyond.” The Georgia BioGENEius Challenge is part of Georgia Life Sciences’ broader commitment to advancing workforce development and fostering innovation across the state’s rapidly growing life sciences ecosystem.
