Based on this new feedback from FDA outlining a clear and feasible path forward for Contrave, the Company's three near-term priorities for the program are to: (1) finalize the trial protocol with FDA; (2) re-engage with parties that expressed interest in partnering the ex-North American markets for Contrave; and (3) implement the CVOT as soon as it is able."In my experience, Contrave demonstrated great potential for the treatment of obesity in a broad range of patients," said Ken Fujioka, MD, director of the Nutrition and Metabolic Research Center and The Center for Weight Management at the Scripps Clinic, and investigator for the Contrave Obesity Research Program. "On behalf of those working hard to address this significant unmet need, I am pleased to see that a pragmatic approach to bringing this therapy to market appears to be taking shape."
