Sage Therapeutics and Biogen Initiate Rolling Submission of New Drug Application (NDA) to U.S. Food and Drug Administration for Zuranolone for the Potential Treatment of Major Depressive Disorder (MDD)

CAMBRIDGE, Mass.–()–Sage Therapeutics, Inc. (Nasdaq: SAGE) and Biogen Inc. (Nasdaq: BIIB) initiated a rolling submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for zuranolone in the treatment of major depressive disorder (MDD). Zuranolone is an investigational two-week, once-daily oral drug being developed for MDD and postpartum depression (PPD). The companies have submitted the nonclinical module of the NDA to the FDA and plan to submit the remaining components for the MDD filing in the second half of 2022.

Data from the completed studies of zuranolone in the LANDSCAPE and NEST clinical development programs, including data from the ongoing open-label SHORELINE Study in MDD, as well as data from the completed clinical pharmacology studies, will comprise the full submission package. The rolling submission process allows completed sections of an NDA to be submitted to the FDA for review on an ongoing basis.

There are millions of people living with depression and the initiation of the rolling NDA submission brings us one step closer to our goal of offering zuranolone as a potential new treatment option,” said Barry Greene, Chief Executive Officer at Sage. “We believe the results from the LANDSCAPE and NEST programs, in which zuranolone demonstrated rapid and sustained effects and a well-tolerated safety profile in clinical trials, support zuranolone as a potential novel treatment option for MDD, if approved. We look forward to providing an update when the rolling submission for zuranolone in MDD is complete, which we expect to occur in the second half of this year.”

Zuranolone has the potential to help address a significant unmet medical need in depression as an innovative option in a therapeutic area where little has changed in the past 30 years,” said Priya Singhal, M.D., M.P.H., Head of Global Safety and Regulatory Sciences and Interim Head of R&D at Biogen. “We are committed to advancing the science and developing new approaches to treating mental health, a major public health challenge that was exacerbated by the COVID-19 pandemic.”

Zuranolone was granted Fast Track Designation by the FDA in 2017 in MDD and Breakthrough Therapy Designation in 2018. Sage and Biogen plan to submit an associated NDA filing for PPD in the first half of 2023.

About Zuranolone

Zuranolone (SAGE-217/BIIB125) is a once-daily, two-week, investigational drug in development for the treatment of major depressive disorder (MDD) and postpartum depression (PPD). Zuranolone is an investigational oral neuroactive steroid (NAS) GABA-A receptor positive allosteric modulator (PAM). The GABA system is the major inhibitory signaling pathway of the brain and central nervous system and contributes to regulating brain function. Zuranolone has been granted Fast Track and Breakthrough Therapy Designation for MDD and Fast Track Designation for PPD by the U.S. Food & Drug Administration.

Zuranolone is being evaluated in the LANDSCAPE and NEST clinical development programs. The two development programs include multiple studies examining use of zuranolone in several thousand people with a variety of dosing, clinical endpoints, and treatment paradigms. The LANDSCAPE program includes five studies of zuranolone in people with MDD (MDD-201B, MOUNTAIN, SHORELINE, WATERFALL, and CORAL Studies). The NEST program includes two placebo-controlled studies of zuranolone in people with PPD (ROBIN and SKYLARK Studies). Additionally, Shionogi completed a Phase 2 study of zuranolone in Japan in people with MDD.

About Major Depressive Disorder (MDD)

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 more than 21 million adults1 in the U.S. and approximately 280 million people2 worldwide suffer from depression. While antidepressants are widely used to treat MDD, large-scale studies have demonstrated the need for additional therapies with a differentiated profile.

About Postpartum Depression (PPD)

Postpartum depression (PPD) is one of the most common medical complications during and after pregnancy. PPD can have a serious negative impact on a woman, including significant functional impairment, depressed mood and/or loss of interest in her newborn, and associated symptoms of depression such as loss of appetite, difficulty sleeping, motor challenges, lack of concentration, loss of energy and poor self-esteem. PPD is estimated to affect approximately one in eight women who have given birth in the U.S. or approximately 500,0003 women annually.
