Results from pivotal trial showed treatment with SAGE-217 resulted in rapid, clinically meaningful improvement in major depressive disorder (MDD) symptoms across multiple measures and time points

SAGE-217 is currently being investigated in the Phase 3 MOUNTAIN trial for the treatment of MDD, with results expected in Q4 2019 or Q1 2020

Sage Therapeutics (NASDAQ: SAGE), a biopharmaceutical company committed to developing novel therapies with the potential to transform the lives of people with debilitating brain disorders, today announced that the New England Journal of Medicine (NEJM) published full results from the double-blind, randomized, placebo-controlled Phase 2 study evaluating SAGE-217 as a treatment for major depressive disorder (MDD). In the study, SAGE-217, taken orally, once daily, showed a rapid, statistically significant reduction in Hamilton Rating Scale for Depression (HAM-D) total scores versus placebo beginning the morning following the first dose (Day 2) and sustained through the primary endpoint of Day 15 (-7.1 difference, p<0.001). At Day 15, 64% of patients who received SAGE-217 achieved remission, defined as a score of 7 or less on the HAM-D scale, compared with 26% of patients who received placebo. Additionally, at Day 15 the HAM-D response rates were 78.6% versus 40.5% in the SAGE-217 and placebo groups, respectively.

Results published in NEJM also include additional data from multiple secondary endpoints, all of which generally favored SAGE-217 at the end of treatment (Day 15). In the study, SAGE-217 was generally well tolerated with a safety profile consistent with that seen in earlier SAGE-217 trials. Overall reports of treatment emergent adverse events (TEAEs) were 53.3% in the SAGE-217 group and 45.5% in the placebo group. No serious adverse events or deaths occurred during the trial.

“The findings published in the New England Journal of Medicine suggest the potential for SAGE-217 to be developed as a novel treatment option for people living with major depressive disorder,” said Anthony J. Rothschild, M.D., Irving S. and Betty Brudnick Endowed Chair of Psychiatry, professor of psychiatry and psychiatry department vice chair for research at the University of Massachusetts Medical School and an author on the manuscript. “Current treatments can take many weeks to work yet patients often experience side effects almost immediately. The significant and rapid improvements in depression and anxiety symptoms observed with SAGE-217 in this trial, combined with the response, remission and safety data, are extremely encouraging for a clinical disorder that can have such debilitating effects on people’s lives.”

Major depressive disorder causes a persistent feeling of sadness and loss of interest in daily activities, often affecting how a person feels, thinks and behaves, and can lead to a variety of emotional and physical problems. It affects more than 17 million American adults, or about 6.8% of the U.S. population age 18 and older in a given year, and is one of the most common, but serious, mood disorders impacting people of all ages, races, and socioeconomic status.

“Our ongoing research into the treatment and management of depression, and other mood disorders, is driven by an ultimate goal of transforming the lives of people suffering from these conditions,” said Steve Kanes, M.D., Ph.D., chief medical officer of Sage Therapeutics. “The Phase 2 results suggest SAGE-217, if successfully developed, may offer a rapid-acting, well-tolerated, and durable therapy, which could change the way depression is treated. The ongoing clinical program for SAGE-217 in major depressive disorder and postpartum depression is intended to generate key efficacy and safety information needed to support a submission for regulatory approval and to further inform use if the drug is approved.”

About the placebo-controlled pivotal Phase 2 trial of SAGE-217 in MDD In the randomized, double-blind, parallel-group, placebo-controlled trial, 89 eligible patients (with a minimum total score of 22 on the Hamilton Rating Scale for Depression at baseline) were randomized in a 1:1 ratio to receive SAGE-217 capsules (30 mg) (n=45) or matching placebo (n=44). All doses of study drug were administered at night with food. The study consisted of a 14-day treatment period and a 4-week follow-up period. The mean HAM-D total scores at baseline were 25.2 for the SAGE-217 group and 25.7 for the placebo group (overall range 22-33), representing patients with moderate to severe MDD. Approximately 90% of patients in each group completed the study. The most common treatment emergent adverse events (≥5%) in the SAGE-217 group included headache (17.8%), nausea (11.1%), dizziness (11.1%), and somnolence (6.7%).

About Major Depressive Disorder Major depressive disorder (MDD) is a common but serious mood disorder in which people experience depressive symptoms that impair their social, occupational, educational or other important functioning, such as a depressed mood or loss of interest or pleasure in daily activities, consistently for at least a two-week period. It is estimated that approximately 17 million people in the U.S. suffer from MDD each year. While antidepressants are widely used to treat MDD, large-scale studies have demonstrated the need for additional therapies.

About SAGE-217 SAGE-217 is a next generation positive allosteric modulator that has been optimized for selectivity to synaptic and extrasynaptic GABAA receptors and has a pharmacokinetic profile intended for periods of daily oral dosing. The GABA system is the major inhibitory signaling pathway of the brain and central nervous system (CNS), and contributes significantly to regulating CNS function. SAGE-217 is currently being developed for major depressive disorder, postpartum depression, and certain other mood disorders.
