CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Sage Therapeutics, Inc. (NASDAQ:SAGE), a clinical-stage biopharmaceutical company developing novel medicines to treat life-altering central nervous system (CNS) disorders, today reported business highlights and financial results for the first quarter ended March 31, 2017.

"We continue to make good progress in building Sage into a leading CNS company with the potential to deliver differentiated medicines for a variety of central nervous system disorders. We are focused on closing the innovation gap in areas of brain disorders where more breakthroughs for patients are needed," said Jeff Jonas, M.D., Chief Executive Officer of Sage. "We are now nearing completion of enrollment in our lead Phase 3 program in super-refractory status epilepticus (SRSE), and remain focused on completing Phase 3 clinical development of brexanolone in both SRSE and postpartum depression (PPD) in 2017. Further, we continue to advance our growing pipeline of novel product candidates, including our lead oral compound, SAGE-217, in four clinical programs in both mood and movement disorders."

Brexanolone in SRSE - Phase 3 STATUS Trial Update

Sage is nearing completion of enrollment in the Phase 3 STATUS Trial, the first ever global, randomized, double-blind, placebo-controlled trial in SRSE. The Company expects to report top-line results from the STATUS Trial in the third quarter of 2017 after enrollment of an anticipated 126 evaluable patients and completion of all study follow-up periods and data analysis. Sage expects top-line results to include the primary endpoint, safety and tolerability, and select secondary endpoints, including open-label retreatment arm response and the Clinical Global Impression scale.

Top-Line Results from Part A of SAGE-217 Phase 2 in Parkinson's Disease

Sage today announced top-line results from the Part A open-label portion of a Phase 2 clinical trial of SAGE-217 in Parkinson's disease:

Pipeline Update

Sage is advancing a portfolio of novel central nervous system (CNS) product candidates targeting the GABA and NMDA receptor systems. Dysfunction in these systems is known to be at the core of numerous psychiatric and neurological disorders. Sage is pursuing a data-driven approach to CNS drug development by employing efficient human proof-of-concept studies both to uncover activity signals and to help understand future trial methodology, before investing in larger clinical programs.

Forward-Looking Statements

Various statements in this release concern Sage's future expectations, plans and prospects, including without limitation: our expectations regarding development of our product candidates and their potential in the treatment of various CNS disorders; the expected timing of initiation and completion of clinical trials; the anticipated availability and announcement of data and results from clinical trials of our product candidates; our plans for evaluation of new indications and new compounds; our expectations regarding the regulatory pathway for brexanolone (SAGE-547) in the treatment of SRSE in the EU, and our belief that the results of the current development program for brexanolone in SRSE, if successful, will be sufficient for an MAA filing in the EU; our expectations regarding a potential future new drug application and MAA filing and commercial launch of brexanolone, if successfully developed and approved; and our expectations with respect to future cash use and cash needs. These forward-looking statements are neither promises nor guarantees of future performance, and are subject to a variety of risks and uncertainties, many of which are beyond our control, which could cause actual results to differ materially from those contemplated in these forward-looking statements, including the risks that: we may continue to experience slower than expected enrollment and randomization of evaluable patients in the STATUS trial or slower than expected clinical site initiation and enrollment in our other clinical trials, or the potential need for additional analysis or data or the need to enroll additional patients, leading to possible delays in completion of trials or in the availability of data; we may not be able to generate supportive non-clinical data or to successfully demonstrate the efficacy and safety of our product candidates at each stage of clinical development; success in our non-clinical studies or in earlier stage clinical trials may not be repeated or observed in ongoing or future studies involving the same compound or other product candidates, and ongoing and future pre-clinical and clinical results may not support further development of product candidates or be sufficient to gain regulatory approval to launch and commercialize any product; decisions or actions of regulatory agencies may affect the initiation, timing, progress and cost of clinical trials, and our ability to proceed with further clinical studies of a product candidate or to obtain marketing approval or may result in restrictions in an approved indication or the need for additional clinical trials, including the risk that the EMA may, despite scientific advice, decide that the data from our Phase 3 trial in SRSE are not sufficient to support approval; the internal and external costs required for our activities, and to build our organization in connection with such activities, and the resulting use of cash, may be higher than expected, or we may conduct additional clinical trials or pre-clinical studies, or engage in new activities, requiring additional expenditures and using cash more quickly than anticipated; and we may encounter technical and other unexpected hurdles in the development and manufacture of our products which may delay our timing or increase our expenses and use of cash, as well as those risks more fully discussed in the section entitled "Risk Factors" in our most recent Annual Report on Form 10-K, as well as discussions of potential risks, uncertainties, and other important factors in our subsequent filings with the Securities and Exchange Commission. In addition, any forward-looking statements represent our views only as of today, and should not be relied upon as representing our views as of any subsequent date. We explicitly disclaim any obligation to update any forward-looking statements.
