Non-segmental Vitiligo

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.

The main purpose of this multicenter, randomized, double-blind, placebo-controlled Phase 2b study is to investigate the safety and efficacy of GIA632 in participants with NSV and to identify the optimal dose to be promoted into the confirmatory Phase 3 program.

The primary purpose of this study is to evaluate whether the drug EI-001 can help improve vitiligo symptoms. EI-001 is a novel antibody drug that affects the immune system to decrease uncontrolled inflammation. EI-001 has been investigated in human cell cultures, animal studies, and in a Phase 1 healthy volunteer study. The results so far show that EI-001 is a tolerable and potential new treatment for immune diseases such as vitiligo.

The study is being conducted to evaluate the efficacy, and safety of SHR0302 tablets as single therapy or in combination with SHR0302 Base gel for patients with non-segmental vitiligo.

This clinical trial is a multicenter, randomized, double-blind, controlled phase II clinical study

This randomized controlled trial aims to compare the efficacy of needling versus microneedling, both followed by narrowband UVB therapy, in achieving repigmentation in patients with localized stable non-segmental vitiligo.
