Recent Pivot to COVID-19 Vaccine Development;

Continued Advancements in Other Infectious Disease and Immuno-Oncology Programs

ATLANTA, GA, March 25, 2020 – GeoVax Labs, Inc. (OTC: GOVX), a biotechnology company developing human immunotherapies and vaccines against infectious diseases and cancer, today announced its financial results for the year ended December 31, 2019 and provided an update on its corporate development progress.

David Dodd, President & CEO, commented, “During the past year and the early months of 2020, GeoVax made substantial progress in various areas of product development. This was combined with tough capital restructuring decisions that, while painful at the time, have now resulted in GeoVax being better positioned for future financing efforts in support of our programs and increasing shareholder value. I am pleased to share a few highlights here.”

Coronavirus Vaccine – In January 2020, we announced our initiation of efforts to develop a vaccine against novel coronavirus disease (COVID-19) caused by the SARS-Cov-2 coronavirus including a letter of intent for a collaboration with BravoVax, a vaccine developer in Wuhan, China. On March 18, 2020, we provided an update on the progress of our program, including the completion of three vaccine candidates and plans for advancing to human clinical trials. Our vaccine has been added to the “Draft Landscape of COVID-19 Candidate Vaccines” by the World Health Organization (link). We will continue to provide updates on our progress with this very important program.

Cancer Immunotherapy – In September 2019, we incorporated Immutak Oncology, Inc as a wholly-owned subsidiary of GeoVax. We established Immutak to focus on the advancement of our immuno-oncology programs and to seek additional, complementary technologies and clinical-stage products in the oncology space. We intend to leverage the work completed and ongoing with our collaborators at the University of Pittsburgh, ViaMune, Leidos, and others, and have initiated a separate financing effort in support of these programs. We believe developing our programs in this area to be a key component for strengthening the valuation of GeoVax and providing future value growth opportunity.

HIV Vaccines (Therapeutic) – We are participating in a planned clinical trial led by researchers at American Gene Technologies (AGT) to develop a therapy aimed at eliminating HIV from infected people (a “functional cure”). In late 2019, AGT submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for its lead HIV program, AGT103-T, a lentiviral vector-based gene therapy. Upon clearance by the FDA, this IND will allow AGT to initiate a Phase 1 clinical trial that will investigate the safety of AGT103-T in humans, measure key biomarkers, and explore surrogate markers of efficacy. GeoVax will provide our novel MVA-VLP-HIV vaccine (MVA62B) for evaluation in an arm of the clinical trial in combination with AGT103-T. AGT has recently stated their intention to begin recruiting patients for the Phase 1 study in mid-2020.

In November 2019, we entered into an agreement with the University of California, San Francisco (UCSF), whereby we will participate in a collaborative effort to develop a combinational therapy aimed at inducing remission in HIV-positive individuals (another approach toward a “functional cure”). The studies will be conducted with funding from amfAR, The Foundation for AIDS Research. The proposed clinical trial will enroll 20 HIV-infected adults who are on stable and effective anti-retroviral therapy (ART) and will involve a combination of vaccines, drugs and biologics. As with the AGT trial, GeoVax will provide MVA62B for use in the studies. Patient enrollment for the clinical trial is expected to commence during 2020.

HIV Vaccines (Preventive) – The development of our preventive HIV vaccine (GOVX-B11) from preclinical studies to human clinical trials has been financially supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).  The HIV Vaccine Trials Network (HVTN) with support from NIAID, has conducted multiple human clinical trials of our preventive HIV vaccine candidates, and continues advancing our vaccine in clinical studies. We now are planning for a new Phase 1 human clinical trial (designated HVTN 132) with operational support from the HVTN and funding from the NIAID. The primary objectives of HVTN 132 will be to further assess the safety, tolerability and immunogenicity (elicited antibody responses) of a prime-boost regimen of GOVX-B11, in combination with protein boost vaccines. The start of HVTN 132 has been delayed due to clarification of components other than our vaccine, but we currently expect HVTN to commence patient enrollment in late 2020.

Malaria Vaccine – In early 2019, we began a collaboration with Leidos, Inc. to develop malaria vaccine candidates. The work continued through 2019 and was expanded in early 2020 with support under a contract to Leidos from the United States Agency for International Development (USAID) Malaria Vaccine Development Program (MVDP). Leidos has been tasked by USAID to advance promising vaccine candidates against P. falciparum malaria and selected the GeoVax MVA-VLP platform to be a part of this development effort. Our collaboration with Leidos complements our ongoing malaria vaccine development project with Burnet Institute in Australia.

Emerging Infectious Disease Vaccines – The ongoing COVID-19 pandemic exemplifies the threat to global health posed by emerging infectious diseases, those known and unknown (so called “Disease X”). In addition to our COVID-19 vaccine, GeoVax has developed vaccines for several other pathogens, including Ebola, Marburg, Lassa fever, and Zika virus, each of which represents a threat to world populations. In preclinical animal models, we have demonstrated 100% protection with our vaccines against each of these viruses. Our Lassa fever vaccine continues to progress toward nonhuman primate testing and manufacturing process development in preparation for human clinical trials through grant support from the U.S. Department of Defense.

Capital Restructuring – On January 3, 2020, our stockholders approved a 1-for-2000 reverse split of our common stock, which was executed on January 21. While this action was drastic, it was necessary in order to provide for sufficient authorized shares of our common stock both to fulfill our obligations to holders of our convertible preferred stock, as well as provide for additional authorized shares of common stock for use in future capital raises. As of December 31, 2019, we had approximately $2.5 million (stated value) of convertible preferred stock on our balance sheet which has now been reduced to $400,000, and our outstanding common shares stands at 13,791,601. This restructuring now places us in a better position for negotiating future financing transactions under more beneficial terms.

Financial Review

GeoVax reported a net loss for the year ended December 31, 2019 of $2.4 million, as compared to $2.6 million for the year ended December 31, 2018.

About GeoVax

GeoVax Labs, Inc. is a clinical-stage biotechnology company developing human vaccines against infectious diseases and cancer using a novel proprietary vaccine platform (GV-MVA-VLPTM). On this platform, MVA, a large virus capable of carrying several vaccine antigens, expresses proteins that assemble into VLP immunogens within (in vivo) the person receiving the vaccine. The production of VLPs in the person being vaccinated mimics virus production in a natural infection, stimulating both the humoral and cellular arms of the immune system to recognize, prevent, and control the target infection. The GV-MVA-VLPTM derived vaccines can elicit durable immune responses in the host similar to a live-attenuated virus, while typically providing the safety characteristics of a replication-defective vector.

GeoVax’s current development programs are focused on preventive vaccines against COVID-19, HIV, Zika, hemorrhagic fever viruses (Ebola, Sudan, Marburg, and Lassa), and malaria, as well as therapeutic vaccines against chronic Hepatitis B infections and multiple cancers. The Company has developed preventive HIV vaccine candidate (GOVX-B11) for the clade B subtype of HIV prevalent in the Americas, Western Europe, Japan, and Australia and the clade C subtype prevalent in Africa and India. GOVX-B11 is scheduled for inclusion in an upcoming human clinical trial managed by the HVTN with the support of the National Institutes of Health (NIH). GeoVax’s clade B HIV vaccine is also part of collaborative efforts to develop an immunotherapy as a functional cure for HIV.
