Non-Segmental Vitiligo (NSV)

This study is a prospective, multicenter, real-world observational study to assess the clinical efficacy and safety of topical 1.5% Ruxolitinib phosphate cream used in combination with systemic corticosteroids in a real-world clinical setting. The study plans to observe patients aged 12 years and older with active, progressive non-segmental vitiligo involving the face. All treatments are prescribed based on standard routine clinical care and medical practice guidelines. Participants will apply Ruxolitinib cream twice daily to affected skin areas for up to 24 weeks alongside a standard corticosteroid regimen. The primary goal of the study is to evaluate how many patients achieve a 75% or greater improvement in their facial vitiligo patches after 12 weeks of combined treatment. Safety and side effects will also be closely monitored throughout the 24-week period.

The purpose of this study is to evaluate how well LY4005130 is tolerated and what side effects may occur in participants with non-segmental vitiligo (NSV) when compared with placebo. The study drug will be administered intravenously (IV) (into a vein in the arm). Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. The study will last approximately 48 weeks, including screening.

This study tests D-2570, an investigational drug, in people with non-segmental vitiligo to check its safety and effect on skin discoloration. Eligible participants will take D-2570, or a placebo, once daily for 24 weeks in a double-blind setting. Most will then continue into a 24-week extension phase, where those on 27 mg or placebo will switch to one of the lower doses. All participants will have a 4-week safety follow-up after treatment ends, with regular check-ups and blood tests throughout the study.

This is a multicenter, randomized, double-blind, placebo-controlled Phase II clinical trial designed to assess the efficacy, safety, and tolerability of LW402 tablets in participants with non-segmental vitiligo. Drawing on the prior/preclinical data of LW402 tablets, this clinical trial will incorporate three dose groups: 50 mg twice daily (BID), 100 mg BID, and 150 mg BID. The trial will be structured into a screening period (maximum 5 weeks), a treatment period (52 weeks, encompassing a 24-week main trial phase and a 28-week extension phase), and a safety follow-up period (4 weeks). The maximum duration of participation in this study will be 61 weeks. Following the completion of 24-week data collection for all trial participants, unblinding will be performed in accordance with the pre-specified procedure. Subsequently, based on the unblinded data results, regulatory communication will be conducted with the Center for Drug Evaluation (CDE) regarding the initiation of the Phase III confirmatory clinical trial. Participants who have undergone unblinding will continue to attend scheduled study visits to complete the trial.

This study is to assess the burden of disease in adolescent and adult participants with moderate or severe alopecia areata (AA), non-segmental vitiligo (NSV), or moderate to severe hidradenitis suppurativa (HS) in a large global real-world participant population.
