Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group A: Ruxolitinib + Narrow-Band Ultraviolet B Phototherapy (NB-UVB); Participants will initially apply ruxolitinib 1.5%mg cream as a monotherapy. At week 12, those who have < 25% improvement in total body Vitiligo Area Scoring Index (T-VASI25) will have NB-UVB phototherapy added to their ruxolitinib 1.5% cream BID regimen. NB-UVB will be given 3 times per week starting at Week 12 through Week 48 (36 weeks). For participants who receive combination therapy, NB-UVB machines will be supplied by the sponsor for at home use during the study.	Drug: Ruxolitinib 1.5% cream; Ruxolitinib cream 1.5% applied twice a day (BID).; Device: NB-UVB phototherapy; NB-UVB (311-312 nm) phototherapy is an established treatment modality for vitiligo. Starting dose will be 200 mJ/cm2 and dose may be increased by 10% at each visit; Other Names: Narrow-Band Ultraviolet B Phototherapy
Experimental: Group B: Ruxolitinib Monotherapy; Participants will apply ruxolitinib 1.5% cream BID as monotherapy. Participants who have ≥ T-VASI25 at Week 12 will continue on ruxolitinib 1.5% cream BID alone.	Drug: Ruxolitinib 1.5% cream; Ruxolitinib cream 1.5% applied twice a day (BID).

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Total Body Vitiligo Area Scoring Index (T-VASI) at Week 48	T-VASI was calculated with contributions from 6 body sites. The percentage of vitiligo involvement was estimated in hand units (percentage of body surface area [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 body 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 body site and summing the values (range: 0-100; lower scores indicate increased improvement).	Baseline; Week 48

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Any Treatment-emergent Adverse Event (TEAE)	An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. An AE could therefore have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study cream. A TEAE was defined as any AE reported for the first time or the worsening of a pre-existing event after the first application of study drug.	up to approximately 52 weeks
