Vitiligo is a long-term autoimmune condition that causes the skin to lose its color due to the immune system mistakenly attacking pigment-producing skin cells called melanocytes. This leads to patches of skin with less or no pigment, often appearing symmetrically on both sides of the body in the nonsegmental form of vitiligo. The study aims to evaluate the safety, effectiveness, and tolerability of the drug zasocitinib in adults with nonsegmental vitiligo. Participants will receive oral capsules of zasocitinib at low, medium, or high doses for up to 52 weeks. Some participants will initially receive a placebo for 24 weeks, then switch to medium or high doses of zasocitinib for the remainder of the study. The placebo capsules look identical to zasocitinib but do not contain active medicine. The study uses a randomized, double-blind design with several experimental groups receiving different doses or placebo. During the study, participants will visit the clinic 11 times over one year. Researchers will assess the improvement in vitiligo using facial and total Vitiligo Area Scoring Index F-VASI and T-VASI at baseline and week 24. Safety and tolerability will also be monitored throughout. The primary outcome is the percentage of participants achieving at least 75% improvement in F-VASI at week 24. Secondary outcomes include other measures of vitiligo area improvement. Participants health and response to treatment will be closely followed until the studys end.

Researchers are studying the use of ruxolitinib cream in children aged 6 to under 12 years who have nonsegmental vitiligo. The study aims to evaluate how well and how safely the cream works for treating this condition, which causes loss of skin color. This is a Phase 3 clinical trial focused on treatment effects in this pediatric population. Participants are assigned to one of three groups receiving either ruxolitinib cream at 0.75% or 1.5%, or a matching vehicle placebo cream. Each cream is applied topically as a thin film twice daily to the affected skin areas as defined in the study protocol. The treatment period lasts up to 24 weeks, during which changes in skin pigmentation are monitored. Throughout the study, participants undergo regular assessments including evaluations of vitiligo improvement on the face and body using the Vitiligo Area Scoring Index and other scales. Safety is monitored by tracking adverse events and blood levels of the drug at multiple timepoints up to 52 weeks. Quality of life and psychosocial effects are also measured. The total study duration includes treatment and follow-up visits to assess long-term outcomes and safety.

Alopecia areata AA is a condition where the immune system attacks hair follicles, causing hair loss mainly on the head and face but possibly on other body parts. This research evaluates the safety, effectiveness, and tolerance of upadacitinib, an approved drug, in adolescents and adults with severe AA. The study is a Phase 3 randomized, placebo-controlled, double-blind trial enrolling about 1500 participants worldwide. Participants are randomly assigned to one of three groups receiving different treatments two doses of upadacitinib or placebo. In initial periods, some may switch from placebo to upadacitinib based on their Severity of Alopecia Tool SALT score. Those completing early parts may enter an extension phase receiving upadacitinib for up to 108 weeks. Treatment involves taking oral tablets once daily for up to 160 weeks, with possible re-randomization at Weeks 24 and 52. Throughout the study, participants attend regular clinic visits for medical assessments, blood tests, side effect monitoring, and questionnaires to track treatment effects. Researchers measure hair loss improvement using SALT scores and record adverse events over approximately 164 weeks. Participants are followed for up to 30 days after their last dose for safety monitoring.

This trial is a rollover study for adults who previously participated in specific Incyte-sponsored clinical trials involving the drug povorcitinib. It focuses on people with Hidradenitis Suppurativa HS, a condition being studied to better understand the long-term safety and effects of continuing povorcitinib treatment. The purpose is to monitor participants who have already benefited from povorcitinib in earlier studies, now entering an extended phase to further evaluate safety and treatment outcomes. Participants will continue taking povorcitinib orally, following the same dose and schedule they had in their original parent study. This study does not test new doses or compare treatments but observes continued use of the drug under the established regimen. The study may last for up to approximately three years, reflecting extended monitoring rather than initial treatment phases. During the study, participants will attend scheduled visits for assessments, including tracking any treatment-emergent adverse events and measuring symptom counts related to HS. Researchers will collect safety data over the long term and observe clinical responses. Participants must adhere to study procedures and avoid pregnancy or fathering children as required. The study aims to provide detailed safety information over an extended period while participants remain on the drug regimen from their original trial.
