Summary

This trial is testing whether a certain type of drug can help improve vitiligo, a condition where patches of skin lose their color. The trial is double-blind, meaning neither the participants nor the researchers will know who is receiving the experimental treatment until the trial is over.

Who is the study for?
This trial is for people with non-segmental vitiligo, which includes vitiligo vulgaris or acrofacial vitiligo, that's been diagnosed for at least 3 months. Participants should have a certain amount of facial and body skin affected. They must not be on new medications or changing doses recently, agree to stop other vitiligo treatments during the study, avoid sun exposure and tanning devices, and use contraception if applicable.Check my eligibility
What is being tested?
The trial is testing Crisaborole and PF-07038124 ointments' effectiveness in treating vitiligo both alone and combined with narrow band UVB phototherapy (NBUVB). It's a phase 2A double-blind study where participants are randomly assigned to one of six groups to compare these treatments against sham (fake) therapy.See study design
What are the potential side effects?
Possible side effects may include local skin reactions like burning or itching where the ointment is applied. NBUVB treatment might cause redness or increase the risk of sunburn-like symptoms on treated areas.
