What this trial studies

This is an observational study using CVS Specialty Pharmacy records to identify U.S. adults who filled a zuranolone prescription between June 2025 and May 2026 within 12 months after the end of pregnancy. Participants complete self-reported questionnaires, with the primary outcome measured by the Edinburgh Postnatal Depression Scale (EPDS) at Day 15 after starting treatment. Secondary outcomes include EPDS at Day 45, a subgroup analysis of participants with moderate baseline PPD, breastfeeding status at Day 45, and characterization of treatment use over 45 days via self-report. People with recent prior exposure to zuranolone or brexanolone, bipolar disorder, or who fail to complete baseline surveys before a second dose are excluded per protocol.

Who should consider this trial

Good fit: Ideal candidates are U.S. adults diagnosed with postpartum depression who received and filled a zuranolone prescription through CVS Specialty Pharmacy within 12 months after pregnancy and can complete online questionnaires independently.

Not a fit: Patients with a history of bipolar disorder, recent prior brexanolone or zuranolone exposure, who received two or more doses before screening, or whose pregnancy ended more than 12 months ago are unlikely to be eligible or benefit from this study.

Why it matters

Potential benefit: If successful, the study could show that zuranolone leads to meaningful symptom improvement in the first two weeks after treatment, supporting its use as a rapid option for postpartum depression.

How similar studies have performed: Related neuroactive steroid treatments like brexanolone have shown benefit in PPD, and prior zuranolone studies have suggested symptom improvement though results across trials have been mixed.
