| Abstract: | Aim: To evaluate the efficacy and safety of an oral, once‐daily, 14‐day treatment course of zuranolone in Japanese patients with major depressive disorder (MDD). Methods: This multicenter, randomized, double‐blind, placebo‐controlled study randomized eligible patients (1:1:1) to receive oral zuranolone 20 mg, zuranolone 30 mg, or placebo once daily for 14 days (treatment‐period), followed by two 6‐week follow‐up periods. The primary endpoint was change from baseline in the 17‐item Hamilton Depression Rating Scale (HAMD‐17) total score on Day 15. Results: Overall, 250 patients (enrolled: 07/07/2020–05/26/2021) were randomized to receive placebo (n = 83), zuranolone 20 mg (n = 85), or zuranolone 30 mg (n = 82). The demographic and baseline characteristics were balanced between groups. The adjusted mean (standard error) change from baseline in the HAMD‐17 total score on Day 15 was −6.22 (0.62), −8.14 (0.62), and − 8.31 (0.63) in the placebo, zuranolone 20‐mg, and zuranolone 30‐mg groups, respectively. Significant differences in the adjusted mean (95% confidence interval [CI]) for zuranolone 20 mg versus placebo (−1.92; [−3.65, −0.19]; P = 0.0296) and zuranolone 30 mg versus placebo (−2.09; [−3.83, −0.35]; P = 0.0190) groups were observed on Day 15, and also as early as Day 3. A nonsignificant yet distinct drug‐placebo separation was observed during follow‐up. Somnolence (placebo [3.7%], zuranolone 20 mg [10.6%], and zuranolone 30 mg [20.7%]) and dizziness (3.7%, 9.4%, and 9.8%, respectively) were more common with zuranolone. Conclusion: Oral zuranolone was safe and demonstrated significant improvements in depressive symptoms, as assessed by HAMD‐17 total score change from baseline over 14 days in Japanese patients with MDD.
