KENILWORTH, NJ, USA I April 17, 2018 I Merck (NYSE:MRK), known as MSD outside of the United States and Canada, today announced that the company is beginning two Phase 3 studies of PCV-15 (V114), its investigational polyvalent conjugate vaccine for the prevention of pneumococcal disease. The first study (ClinicalTrials.gov, NCT03480763) will evaluate the safety, tolerability and immunogenicity of PCV-15 followed by Pneumococcal Vaccine Polyvalent one year later in healthy adult subjects 50 years of age or older. The second Phase 3 study (ClinicalTrials.gov, NCT03480802) will evaluate the safety, tolerability and immunogenicity of PCV-15 followed by Pneumococcal Vaccine Polyvalent administered eight weeks later in adults infected with human immunodeficiency virus (HIV).
