First time detailed data for SAGE-547 in postpartum depression (PPD) to be presented

PPD data includes secondary endpoints and timeline of response

SAGE-718 pre-clinical data unveiled in late-breaker

First time data from Sage's NMDA modulator platform to be presented

CAMBRIDGE, Mass., March 28, 2016 (GLOBE NEWSWIRE) -- Sage Therapeutics (NASDAQ:SAGE), a clinical-stage biopharmaceutical company developing novel medicines to treat life-altering central nervous system (CNS) disorders, today announced two upcoming poster presentations at the Society of Biological Psychiatry 71st Annual Scientific Meeting, taking place May 12-14, 2016 in Atlanta, GA.

"For a condition such as PPD, where the treatment options are limited and there are serious health implications for mother and child, the dramatic and sustained reduction in the Hamilton Rating Scale for Depression (HAMD) throughout the treatment period in our four trial participants is highly encouraging. For the first time, we will share detailed data from our previous open-label, proof-of-concept study for SAGE-547 in PPD, including secondary endpoints," said Steve Kanes, M.D., Ph.D., Chief Medical Officer of Sage. "Additionally, the promising preclinical data from our first NMDA positive allosteric modulator candidate, SAGE-718, highlights our expanding development pipeline that focuses on CNS disorders characterized by NMDA hypofunction."

SAGE-547 was well-tolerated in the open-label, proof-of-concept study with no serious adverse events reported during the treatment and follow-up periods and no discontinuations due to adverse events. The only adverse event reported in more than one patient was sedation, observed in two patients.

The schedule for the presentations is as follows:

Date: Thursday, May 12, 2016 Presentation Time: 5:00 p.m. - 7:00 PM (ET) Location: Hyatt Regency Atlanta, Grand Hall West - LL2, Atrium Tower Title: The Open-label, Proof-of-concept Study of SAGE-547 (Allopregnanolone) in the Treatment of Postpartum Depression ( link to abstract)

Date: Friday, May 13, 2016 Presentation Time: 5:00 p.m. - 7:00 PM (ET) Location: Hyatt Regency Atlanta, Grand Hall West - LL2, Atrium Tower Title: Development and Characterization of an NMDA Positive Allosteric Modulator with Effects in Pre-Clinical Models of Psychosis and Cerebrosterol Deficit Disorders ( link to abstract)
