CORAL Phase 3 MDD Topline
Phase 3 efficacy readout for zuranolone added to SSRIs/SNRIs in MDD. Two prior MDD trials (MOUNTAIN, WATERFALL) missed primary endpoints. Watch: HAM-D17 change at week 15 vs. placebo, durability beyond the 14-day dosing course.
What’s at stake
ZURZUVAE (zuranolone) is a once-daily oral pill co-developed by Sage Therapeutics and Biogen that acts as a positive allosteric modulator of GABA-A receptors — the brain's primary inhibitory receptors — to rapidly restore neural balance during depressive episodes. Unlike traditional antidepressants that require continuous daily dosing, zuranolone is given as a short 14-day course intended to reset dysregulated neural circuits. It is the first oral therapy specifically approved for postpartum depression (PPD) and is also being studied as an adjunct to standard antidepressants in major depressive disorder (MDD).
