Vaxcyte’s VAX-31 Meets All Primary Endpoints in Pivotal Phase III OPUS-1 Trial
Vaxcyte's VAX-31 met all primary endpoints in its Phase III OPUS-1 trial, showing non-inferior immune responses across age groups. The vaccine was generally well-tolerated, with mild to moderate reactions. Vaxcyte plans to submit a BLA in the first half of 2028, supported by additional studies and manufacturing data. The company aims to commercialize VAX-31 independently in the U.S. and may seek partnerships for international markets.
