SAGE-547 is an allosteric modulator of GABAA receptors in development for the treatment of adult patients with refractory status epilepticus who have not responded to standard regimens (super-refractory status epilepticus, or SRSE). SAGE is currently evaluating SAGE-547 in a Phase 1/2 clinical trial for the treatment of SRSE. Preliminary data indicate that the first four patients enrolled in the clinical trial met the key efficacy endpoint, in that each was successfully weaned off his or her anesthetic agent while SAGE-547 was being administered. There have also been no reported drug-related serious adverse events in these four patients to date.
"The fast track designation for SAGE-547 recognizes the significant unmet need that exists in the treatment of super-refractory status epilepticus," said Jeff Jonas, MD, chief executive officer of SAGE Therapeutics. "The receipt of orphan drug designation earlier this year for status epilepticus and the fast track designation are both significant regulatory milestones for SAGE-547, and we will continue to work closely with the FDA to advance our lead compound and the additional programs in our pipeline for the treatment of life-threatening CNS disorders."
Fast track designation is granted by the FDA to facilitate the development and expedite the review of drug candidates that are intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical needs.
