Quinupristin and dalfopristin (Intravenous route)

Quinupristin/dalfopristin has been approved for marketing in the United States for vancomycin-resistant Enterococcus faecium (VREF) bacteremia under FDA's accelerated approval regulations that allow marketing of products for use in life-threatening conditions when other therapies are not available. Approval of this indication is based upon quinupristin/dalfopristin’s ability to clear VREF from the bloodstream, with clearance of bacteremia considered to be a surrogate endpoint. There are no results from well-controlled clinical studies that confirm the validity of this surrogate marker .
