Merck BLA Filed for Pneumococcal Conjugate Vaccine
Merck has submitted BLA for V114, an investigational 15-valent pneumococcal conjugate vaccine for use in adults 18 years of age and older. The submission is based on data from Phase 2 and Phase 3 clinical studies in healthy adults and those at increased risk, such as adults with chronic medical conditions, adults with HIV, and those 65 years of age and older, the company says. It describes the vaccine as comprising pneumococcal polysaccharides from 15 serotypes conjugated to a CRM197 carrier protein and includes serotypes 22F and 33F, “which are commonly associated with invasive pneumococcal disease in older adults and are not contained in the pneumococcal conjugate vaccine currently licensed for use in adults.”
