GeoVax Labs reports interim data from Phase 2 trial of GEO-CM04S1

GeoVax Labs announced positive initial safety and immune response findings from its Phase 2 clinical trial at one month following administration of its Covid-19 vaccine, GEO-CM04S1. The trial, evaluating GEO-CM04S1 as a heterologous booster in 63 healthy adults who had previously received the Pfizer or Moderna mRNA vaccine, was fully enrolled at the end of Sept 2023. The study is designed to evaluate the safety and immunogenicity of two GEO-CM04S1 dose levels. The trial remains blinded to dose of vaccine received, with study subjects being followed for a total of one year. To date, there have been no serious adverse events, and adverse events were in line with other routine vaccinations. The immunological responses measured throughout the study period include both neutralizing antibodies against SARS-CoV-2 variants and specific T-cell responses. “We are thrilled by these data and our investigational vaccine designed to protect against severe disease caused by emerging variants of Covid-19,” said David Dodd, GeoVax Chairman and CEO. “These interim data reinforce our resolve to bring our expertise in the development of innovative vaccines to address critical public health needs using new approaches and technologies. We look forward to providing further updates regarding the successful progress of the clinical development of GEO-CM04S1.”
