KENILWORTH, N.J.–(BUSINESS WIRE)–Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the Biologics License Application (BLA) for bezlotoxumab, an investigational antitoxin for prevention of Clostridium difficile (C. difficile) infection recurrence. The FDA granted Priority Review for bezlotoxumab, with a Prescription Drug User Fee Act (PDUFA) action date of July 23, 2016.
The company also has filed a marketing authorization application for bezlotoxumab with the European Medicines Agency (EMA) that is currently under review.
“Recurrence is a major challenge with C. difficile infection, one of the most common healthcare-associated infections in U.S. hospitals,” said Dr. Roy Baynes, senior vice president of clinical development, Merck Research Laboratories. “Currently, there are no therapies approved for the prevention ofC. difficile infection recurrence. As part of Merck’s commitment to the fight against infectious diseases, we look forward to continuing to work with the FDA and EMA to bring forward this novel medicine for appropriate patients.”
The application for bezlotoxumab is based in part on data from the pivotal MODIFY I and MODIFY II clinical trials. Data from these trials were previously presented at the Interscience Conference of Antimicrobial Agents and Chemotherapy (ICAAC) and International Congress of Chemotherapy and Infection (ICC) 2015 joint meeting.
Bezlotoxumab is an investigational antitoxin given in conjunction with standard of care antibiotics that are used in the treatment of C. difficile infection. It is not an antibiotic. Bezlotoxumab is designed to neutralize C. difficile toxin B, a toxin that can damage the gut wall and cause inflammation, leading to C. difficile-associated diarrhea.
