Sage Therapeutics Announces Positive Interim, Topline Data from Open-Label SHORELINE Study of Zuranolone in Patients with MDD

Sage Therapeutics announced interim, topline results from a July data cut of the ongoing Phase 3 open-label SHORELINE Study. This clinical study was designed to naturalistically follow patients with major depressive disorder (MDD) and evaluate the safety and tolerability of zuranolone 30 mg in adults for up to one year. 

The SHORELINE Study (217-MDD-303) is a Phase 3, open-label, 1-year longitudinal study evaluating the safety, tolerability, and need for repeat dosing with zuranolone in adults with MDD. The study comprises two cohorts, one with zuranolone 30 mg as a starting dose and one with zuranolone 50 mg as a starting dose both administered once nightly for 14 days. The need for repeated dosing is assessed every 14 days based on the results of a patient-reported PHQ-9 (≥10) and HAMD-17 (≥20) assessment. There was a minimum of 56 days between zuranolone 14-day courses, to allow for a maximum of five treatments for the follow-up period.

For the primary endpoint of safety and tolerability, the data analyzed to date show that zuranolone was generally well-tolerated in the 30 mg dose and among the initial patients treated with the 50 mg dose. Adverse events reported in the trial during the period analyzed were generally consistent with results seen in previous clinical trials. Nearly half of trial participants with positive response to initial 14-day course of zuranolone 30 mg did not need an additional zuranolone treatment course. For those who needed retreatment with the 30 mg dose, safety, tolerability and efficacy results were similar to those seen in the initial treatment course.

About Zuranolone

Zuranolone (SAGE-217) is an investigational oral neuroactive steroid (NAS) GABAA receptor positive allosteric modulator (PAM). The GABA system is the major inhibitory signaling pathway of the brain and central nervous system and contributes significantly to regulating brain function. Zuranolone has been granted Breakthrough Therapy Designation by the U.S. Food & Drug Administration.

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.
