Summary
Brief summary
Researchers are looking for a new way to treat people with non-segmental vitiligo (NSV). The goal of this study is to learn about the safety of MK-6194 and how well people tolerate it. Researchers also want to learn if people who take MK-6194 have more of a decrease in the amount of vitiligo on their face compared to people who take placebo.
