Elinzanetant for Menopausal Hot Flashes: A 52‑Week Phase 3 Trial Shows Modest, Durable Benefit and Acceptable Safety Profile

OASIS‑3 evaluated once‑daily oral elinzanetant 120 mg vs placebo for 52 weeks in postmenopausal women with moderate–severe vasomotor symptoms. At 12 weeks elinzanetant reduced daily moderate–severe VMS frequency by a least‑squares mean difference of −1.6 vs placebo (P < .001); numerical advantages persisted through 50–52 weeks with no signal for hepatotoxicity or endometrial hyperplasia.
