Abstract
receptor positive allosteric modulator, in major depressive disorder (MDD). -diagnosed MDD, 17-item Hamilton Depression Rating Scale total score (HDRS-17) ≥ 22, and Montgomery-Asberg Depression Rating Scale total score ≥ 32. Patients were randomized to treatment with zuranolone 20 mg, zuranolone 30 mg, or placebo for 14 days, followed by an observation period (days 15-42) and an extended follow-up (days 43-182). The primary endpoint was change from baseline (CFB) in HDRS-17 at day 15. < .05). Incidence of treatment-emergent adverse events was similar between zuranolone and placebo groups; the most common (≥ 5%) were fatigue, somnolence, headache, dizziness, diarrhea, sedation, and nausea. MOUNTAIN did not meet its primary endpoint. Significant rapid improvements in depressive symptoms were observed with zuranolone 30 mg at days 3, 8, and 12. Zuranolone was generally well tolerated in patients with MDD. ClinicalTrials.gov identifier: NCT03672175.
