Following the pre-NDA meeting, the companies confirmed the current efficacy and safety databases are expected to be adequate for filing with confirmed pathways for MDD and PPD
The planned initial submission package will be for the treatment of MDD with an anticipated PPD filing thereafter
CAMBRIDGE, Mass. – October 19, 2021 – Sage Therapeutics, Inc. (Nasdaq: SAGE) and Biogen Inc. (Nasdaq: BIIB) today announced their plan to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for zuranolone, an investigational two-week, once-daily therapeutic in the second half of 2022. The planned initial submission package will seek approval of zuranolone for the treatment of major depressive disorder (MDD) and an additional filing for postpartum depression (PPD) is anticipated in the first half of 2023. The decision to submit the application follows recent discussions with the FDA, including a pre-NDA meeting held this fall. Data from completed studies in the LANDSCAPE and NEST programs, as well as data from the ongoing clinical and pharmacology studies, are planned to be included as part of the submission packages.
“In the pre-NDA meeting, the FDA’s response on the regulatory pathway for zuranolone continued to be consistent with previous discussions. In the clinical development programs, zuranolone has shown remarkably consistent, rapid, and sustained reductions in depressive symptoms, including anxiety and sleep loss, in addition to a well-tolerated safety profile. We believe we have a solid filing package with four adequate and well controlled trials now in hand and, if approved, zuranolone will fill a real unmet need and be welcomed by people living with depression,” said Barry Greene, Chief Executive Officer at Sage Therapeutics. “We have identified what we believe is the most efficient path forward for an FDA filing and potential approval.”
Sage and Biogen also announced the CORAL Study is fully enrolled and closed to further screening, with topline data expected in early 2022. The CORAL Study is designed to demonstrate a rapid onset of depression relief when zuranolone is co-initiated with a standard antidepressant therapy.
“We are pleased to share what we believe is an efficient filing pathway for zuranolone, with the goal of bringing a new treatment option to the millions of people who suffer from depression worldwide,” said Alfred Sandrock, Jr., M.D., Ph.D., Head of Research and Development at Biogen. “The efficacy and safety data planned for FDA submission support our vision of zuranolone being an as-needed, two-week, once-daily treatment option for MDD and PPD that produces rapid relief from symptoms within days.”
Sage and Biogen plan to submit a separate and distinct filing for PPD once the ongoing PPD 301-SKYLARK Study completes so as not to affect the MDD review timeline. The companies plan to commence marketing for the approved indications as soon as possible pending the FDA’s approval. The review cycles may allow commercialization of both indications simultaneously, if approved.
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 approximately 19 million people in the U.S. and more than 250 million people worldwide suffer from MDD each year. 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 over 500,000 women annually.
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 Breakthrough Therapy Designation by the U.S. Food & Drug Administration.
Zuranolone is being evaluated in the NEST and LANDSCAPE clinical trial programs. The two development programs include multiple studies examining use of zuranolone in several thousand patients with a variety of dosing, clinical endpoints, and treatment paradigms. The LANDSCAPE program includes five studies of zuranolone in patients with MDD (MDD-201B, MOUNTAIN, SHORELINE, WATERFALL, and CORAL Studies). The NEST program includes two placebo-controlled studies of zuranolone in patients with PPD (ROBIN and SKYLARK Studies). Additionally, Shionogi recently completed a Phase 2 study of zuranolone in Japan.
