Sage Therapeutics, Inc. (Nasdaq: SAGE) and Biogen Inc. (Nasdaq: BIIB) announced the completion of the 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) and postpartum depression (PPD). Zuranolone is an investigational drug being evaluated as a rapid-acting, once-daily, 14-day oral short course treatment in adults with MDD and PPD. The submission completes the NDA filing that was initiated earlier this year.
In the clinical development program to date, zuranolone showed rapid and sustained improvement of depressive symptoms with a generally well-tolerated and consistent safety profile. Zuranolone, a neuroactive steroid, has a novel mechanism of action as a positive allosteric modulator of GABA-A receptors. In people with depression, it may help to rapidly rebalance dysregulated neuronal networks to help restore brain function. Zuranolone targets brain networks responsible for functions such as mood, arousal, behavior, and cognition.
"Based on the data in the LANDSCAPE and NEST programs, we believe that zuranolone has the potential to be a meaningful new therapy for depression," said Priya Singhal, M.D., M.P.H., Head of Global Safety and Regulatory Sciences and Interim Head of R&D at Biogen. "We look forward to working with the FDA as this filing progresses."
"Mental health is a highly underserved area with an urgent unmet need for innovative therapies. We need to rethink how MDD and PPD are treated. Existing treatments often take weeks to months to provide symptom relief, and patients may need to cycle through multiple treatment options to fully address their symptoms. People with MDD and PPD deserve better," said Laura Gault, M.D., Ph.D., Chief Medical Officer at Sage. "We believe that zuranolone, if approved, could evolve the way depression is treated and this submission brings us one step closer to that goal."
The NDA submission includes data from the LANDSCAPE and NEST development programs for zuranolone. The LANDSCAPE program includes five studies of zuranolone in adults with MDD (MDD-201B, MOUNTAIN, SHORELINE, WATERFALL, and CORAL Studies). The NEST program includes two studies of zuranolone in adult women with PPD (ROBIN and SKYLARK Studies).
Zuranolone was granted Fast Track Designation by the FDA in 2017 and Breakthrough Therapy in 2018 for MDD. The FDA also granted Fast Track Designation for PPD in 2022.
Zuranolone (SAGE-217/BIIB125) is a once-daily, 14-day, investigational drug in development for the treatment of major depressive disorder (MDD) and postpartum depression (PPD). Zuranolone is an 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 women with PPD (ROBIN and SKYLARK Studies). Additionally, Shionogi completed a Phase 2 study of zuranolone in Japan in people with MDD.
