A Randomized, Double-Blind, Vehicle-Controlled Study to Evaluate the Mechanism of Action of Ruxolitinib Cream for Vitiligo (TRuE-V MOA)

Inclusion Criteria:

• A clinical diagnosis of nonsegmental vitiligo with depigmented areas including ≥ 0.5% BSA on the face, ≥ 0.5 F-VASI, ≥ 3% BSA on nonfacial areas, and ≥ 3 T-VASI; total body vitiligo area (facial and nonfacial) should not exceed 50% BSA.
• At least 1 active vitiligo lesion (eg, such as confetti lesion, trichrome appearance, pinkish rim, or other evidence of inflammatory activity) at the site for skin biopsy.
• Agree to discontinue all agents used to treat vitiligo from screening through the final safety follow-up visit.
• Over-the-counter preparations deemed acceptable by the investigator and camouflage makeups are permitted.

Exclusion Criteria:

• No pigmented hair within any of the vitiligo areas on the face.
• Other forms of vitiligo (eg, segmental) or other differential diagnosis of vitiligo or other skin depigmentation disorders (eg, piebaldism, pityriasis alba, leprosy, postinflammatory hypopigmentation, progressive macule hypomelanosis, nevus anemicus, chemical leukoderma, and tinea versicolor).
• Used depigmentation treatments (eg, monobenzone) for past treatment of vitiligo or other pigmented areas except hydroquinone.
• Any other skin disease that, in the opinion of the investigator, would interfere with the study medication application or study assessments.
• Conditions at baseline that would interfere with evaluation of vitiligo.
• Use of any protocol-defined treatments within the indicated washout period before baseline.
