Official title: A Phase 2a, Proof of Concept, Multicenter, Double Blind, Randomized, Placebo Controlled, Parallel Group Trial to Assess the Efficacy and Safety of ACT-777991 in Adults With Non-segmental Vitiligo
Status: Recruiting now
Description:
The purpose of this clinical trial is to learn how well ACT-777991 works, how safe it is and how well it is tolerated by adults with non-segmental vitiligo. The main question this clinical trial aims to answer is: • Can ACT-777991 help return color to the skin of the face of adults with non-segmental vitiligo? Researchers will compare ACT-777991 to placebo (a look-alike inactive treatment that contains no medicine) to see if ACT-777991 works to treat non-segmental vitiligo. Trial participants will: • Take the trial intervention (either ACT-777991 or placebo) daily for 24 weeks. • Visit the clinic 7 times for check-up and tests.
Phase: Phase 2.
