Psoriasis drug may affect birth control: small study investigates

NCT ID NCT07181343

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This completed Phase 1 trial in 18 healthy women aged 18–40 tested whether taking the experimental psoriasis drug HS-10374 changes how the body absorbs and clears the birth control pill Yasmin. Participants took Yasmin alone and then again after a course of HS-10374. Researchers measured drug levels in the blood to see if there is a meaningful interaction. The results will guide safe co-prescribing for women with psoriasis who need contraception.
