简要总结
The purpose of this study is to evaluate the efficacy and safety of ruxolitinib cream in adolescent and adult participants with non-segmental vitiligo for whom total body involved vitiligo area (facial and nonfacial) does not exceed 10% body surface area (BSA).

入选标准
- •Clinical diagnosis of non-segmental vitiligo with depigmented area including ≥ 0.5% BSA on the face, ≥ 0.5 F-VASI, ≥ 3% BSA on nonfacial areas, ≥ 3 T-VASI, and total body vitiligo area (facial and nonfacial) not exceeding 10% BSA.
- •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.
- •Must be willing to take appropriate contraceptive measures to avoid pregnancy or fathering a child for the duration of study participation.
排除标准
- •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).
- •Have used depigmentation treatments (eg, monobenzone) for past treatment of vitiligo or other pigmented areas.
- •Use of protocol-defined treatments within the indicated washout period before baseline.

Participants who completed the Week 24 assessments with no safety concerns could continue into the 28-week Treatment-Extension Period. Participants who applied ruxolitinib cream 1.5% BID during the Double-Blind Period continued to apply ruxolitinib cream 1.5% BID for an additional 28 weeks in the Treatment-Extension Period.
干预措施: Ruxolitinib cream (Drug)
Treatment-Extension Period: Vehicle cream to Ruxolitinib cream 1.5% BID
Participants who completed the Week 24 assessments with no safety concerns could continue into the 28-week Treatment-Extension Period. Participants who applied vehicle cream BID during the Double-Blind Period applied ruxolitinib cream 1.5%m BID for 28 weeks in the Treatment-Extension Period.

结局指标
主要结局
Percentage of Participants Achieving a ≥ 75% Improvement From Baseline in the Face Vitiligo Area Scoring Index (F-VASI75) Score at Week 24
时间窗: Baseline; Week 24
An F-VASI75 responder achieved at least 75% improvement from Baseline in F-VASI, measured by the percentage of vitiligo involvement (percentage of body surface area \[BSA\]) and the degree of depigmentation: 0% (no depigmentation), 10% (only specks of depigmentation), 25% (pigmented area exceeded depigmented area), 50% (depigmented and pigmented area was equal), 75% (depigmented area exceeded pigmented area), 90% (specks of pigment), or 100% (no pigment). The percentage of BSA (hand unit) vitiligo involvement was estimated to the nearest 0.1% by the Investigator using the Palmar Method. The Investigator used his/her hand to mimic the participant's hand size to evaluate the percentage of BSA vitiligo involvement. F-VASI was then derived by multiplying the values assessed for the vitiligo involvement by the percentage of affected skin for each site on the face and summing the values of all sites (possible range: 0-3; lower scores indicate increased improvement).
