FDA Extends Review of Titan Opioid Addiction Drug
FDA has extended by three months its review of a Titan Pharmaceuticals and partner Braeburn Pharmaceuticals NDA for the maintenance treatment of opioid addiction. The agency has set a new review target date of 5/27.
Following a Psychopharmacologic Advisory Committee meeting in January, FDA requested additional changes to the Risk Evaluation and Mitigation Strategy (REMS) portion of the NDA, which were recently submitted by Braeburn. The agency determined that the submission qualified as a major amendment to the NDA during the review process and elected to extend the action date.
The advisory committee voted 12 to 5 to recommend approval of the implant that is designed to reduce cravings in opioid dependent patients. The agency noted during the meeting that as an implantable formulation, probuphine is intended to be difficult to divert or abuse, and less likely than sublingual buprenorphine formulations to be accidentally ingested by small children. It also offers the possibility of improved adherence to treatment and improved patient convenience.
