Summary
Brief summary
The purpose of this study is to evaluate the efficacy, safety, and tolerability of MK-6194 in
participants with non-segmental vitiligo. The primary hypothesis is that at least 1 MK-6194
dose is superior to placebo with regards to percent change from baseline in Facial Vitiligo
Area Scoring Index (F-VASI) at Week 24.
