Outcomes
Primary Outcome Measures
Percentage of Participants Treated With Ruxolitinib Cream Who Achieved a ≥ 50% Improvement From Baseline in Facial Assessment of the Vitiligo Area and Severity Index Score (F-VASI50) Compared With Participants Treated With Vehicle at Week 24
An F-VASI50 responder achieved at least 50% 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).
Secondary Outcome Measures
Percentage of Participants Who Achieved a Facial Assessment of the Physician's Global Vitiligo Assessment (F-PhGVA) of Clear or Almost Clear
The severity of vitiligo was assessed by the physician using the PhGVA, which has a 5-point scale. 0=clear, no signs of vitiligo; 1=almost clear, only specks of depigmentation present; 2=mild disease, pigmented and depigmented areas are equal; 3=moderate disease, more or complete depigmentation (may include < 30% hair whitening); 4=severe disease, complete depigmentation plus > 30% hair whitening.
Percentage of Participants Who Achieved a ≥ 50% Improvement From Baseline in Full Body Assessment of Vitiligo Area and Severity Index (T-VASI) at Week 52
T-VASI was measured by the percentage of vitiligo involvement from all body regions (percentage of BSA; assessed by the Investigator) 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 present), 100% (no pigment present). T-VASI was derived by multiplying the vitiligo involvement values by the percentage of affected skin for each body site and summing all values (possible range: 0-100; lower scores indicate increased improvement).

Mean Change From Baseline in Vitiligo European Task Force (VETF) Scale Scores at Week 24: Total Spreading
The VETF-proposed system combines analysis of extent (0%-100% BSA), stage of disease (staging), and disease progression (spreading); each component is evaluated and reported independently. Staging is based on cutaneous and hair pigmentation in vitiligo patches. Disease is staged 0 to 4 on the largest macule in each of 5 body regions, except hands and feet, which are assessed separately and globally as 1 unique area. Stage 0=normal pigmentation, Stage 1=incomplete pigmentation, Stage 2=complete depigmentation (a few white hairs do not change stage), Stage 3=partial hair whitening (<30%), Stage 4=complete hair whitening; total score of 0 (less severe disease) to 20 (more severe disease). Disease progression is based on assessing the largest patch in each of 5 body areas: -1=regressive vitiligo (ongoing subclinical repigmentation), 0=similar limits, 1=progressive vitiligo (ongoing subclinical depigmentation); total score of -5 (improving disease) to +5 (more severe disease spread).

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).

Percentage Change From Baseline in F-BSA Repigmentation at Week 24
Description
F-BSA involvement was the proportion of the facial body surface area with vitiligo. The area "Face" was defined as including the area on the forehead to the original hairline, on the cheek to the jawline vertically and laterally from the corner of the mouth to the tragus. The area "Face" did not include the surface area of the lips, scalp, ears, or neck, but included the nose and eyelids. Body surface area assessment was performed by the Palmar Method. Body surface area was estimated to the nearest 0.1%. The approximate size of the participant's entire palmar surface (i.e., the palm plus 5 digits) was considered as 1% BSA, and the approximate size of the participant's thumb was considered as 0.1% BSA. Percentage change = ([post-Baseline value minus Baseline value]/Baseline value) X 100.

Mean Change From Baseline in T-VASI Score at Week 24
Description
T-VASI was calculated with contributions from 6 sites. The percentage of vitiligo involvement was estimated in hand units (percentage of BSA estimated to 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 percent BSA vitiligo involvement. The degree of depigmentation for each site was estimated to the nearest percentage: 0% (no depigmentation present), 10% (only specks of depigmentation present), 25% (pigmented area exceeded depigmented area), 50% (depigmented and pigmented area was equal), 75% (depigmented area exceeded pigmented area), 90% (specks of pigment present), 100% (no pigment present). T-VASI was then derived by multiplying the values assessed for the vitiligo involvement by the percentage of affected skin for each site and summing the values (range: 0-100; lower scores indicate increased improvement). Change from Baseline (BL) was calculated as the post-BL value minus the BL value.

at least 0.5% of the total body surface area (BSA) on the face (0.5% BSA is approximately equal to the area of the participant's palm [without digits]) AND
at least 3% of the total BSA on nonfacial areas (3% BSA is approximately equal to the area of 3 of the participant's handprints [palm plus 5 digits]).
Participants who agree to discontinue all agents used to treat vitiligo from screening through the final follow-up visit. Over-the-counter preparations deemed acceptable by the investigator and camouflage makeups are permitted.
Exclusion Criteria:
Conditions at baseline that would interfere with evaluation of vitiligo.
Participants who are receiving any kind of phototherapy, including tanning beds.
Participants with other dermatologic disease besides vitiligo whose presence or treatments could complicate the assessment of repigmentation.
Participants who have used skin bleaching treatments for past treatment of vitiligo or other pigmented areas.
Participants who have received any of the following treatments within the minimum specified timeframes.
Use of any biologic, investigational, or experimental therapy or procedure for vitiligo within 12 weeks or 5 half-lives (whichever is longer) of screening.
Use of laser or light-based vitiligo treatments, including tanning beds, within 8 weeks of screening.
Use of immunomodulating oral or systemic medications (eg, corticosteroids, methotrexate, cyclosporine) or topical treatments that may affect vitiligo (eg, corticosteroids, tacrolimus/pimecrolimus, retinoids) within 4 weeks of screening.
Use of any prior and concomitant therapy not listed above that may interfere with the objective of the study as per discretion of the investigator, including drugs that cause photosensitivity or skin pigmentation (eg, antibiotics such as tetracyclines, antifungals) within 8 weeks of screening.
Participants with a clinically significant abnormal thyroid-stimulating hormone or free T4 at screening.
Participants with protocol-defined cytopenias at screening
Participants with severely impaired liver function.
Participants with impaired renal function.
Participants taking potent systemic cytochrome P450 3A4 inhibitors or fluconazole within 2 weeks or 5 half-lives, whichever is longer, before the baseline visit.
Participants who have previously received JAK inhibitor therapy, systemic or topical.
