Vicriviroc, previously named SCH 417690 and SCH-D, is a pyrimidine CCR5 entry inhibitor of HIV-1. It was developed by the pharmaceutical company Schering-Plough. Merck decided to not pursue regulatory approval for use in treatment-experienced patients because the drug did not meet primary efficacy endpoints in late stage trials. Clinical trials continue in patients previously untreated for HIV.
