In September 2023, Gritstone entered into a contract with the Biomedical Advanced Research and Development Authority ("BARDA") to run a 10,000 participant, randomized Phase 2b double-blinded study to compare the efficacy, safety, and immunogenicity of its COVID-19 vaccine candidate (a samRNA vaccine candidate) with an approved COVID-19 vaccine (the "Phase 2b CORAL Study" or the "Study").
