What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 60 participants in total. It began in 2026-04-14 with a primary completion date of 2027-05.

Brief Summary

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.

Eligibility Criteria

Inclusion Criteria: * Eligible participants must have the following at both screening and baseline: * A clinical diagnosis of non-segmented vitiligo (NSV) for at least 3 months * Body surface area (BSA) involvement of 4% to 60%, inclusive, excluding involvement at palms of the hands, soles of the feet, or dorsal aspect of the feet * BSA involvement of ≥0.5% on the face * F-VASI ≥0.5 and T-VASI ≥3, and * Either active or stable disease at both screening and baseline Exclusion Criteria: * Participants who have other types of vitiligo that are not considered active or stable vitiligo * Currently have active forms of other disorders of pigmentation * Currently have active forms of inflammatory skin disease(s) or evidence of skin conditions that would interfere with evaluation of vitiligo or response to treatment * Have a superficial skin infection within 2 weeks before baseline. Participants may be rescreened after the infection is resolved * Have a history of chronic alcohol abuse, IV drug abuse, or other illicit drug abuse within 1 year prior to screening * Have a history or presence of cardiovascular, respiratory, hepatic, gastrointestinal, endocrine, hematological, neurological, or neuropsychiatric disorders or any other serious and/or unstable illness that, in the opinion of the investigator, could constitute an unacceptable risk when taking the study intervention or interfere with the interpretation of data * Any previous JAK inhibitor therapy, systemic or topical (for example, ruxolitinib, tofacitinib, baricitinib, upadacitinib, filgotinib, lestaurtinib, pacritinib) will NOT be allowed. Participant MUST be JAK inhibitor therapy-naïve
