Study Endpoints

Primary Endpoints

WI-NRS4 Response at Week 12
Baseline; Week 12

WI-NRS4 was defined as the percentage of participants achieving a ≥4-point improvement (reduction) in Worst-Itch Numeric Rating Scale (WI-NRS) score from baseline. The WI-NRS is a patient-reported outcome comprised of a single item rated on a scale from 0 ("no itch") to 10 ("worst imaginable itch"). Participants assessed their worst level of prurigo nodularis-related itch during the past 24 hours on a scale of 0 to 10. The WI-NRS score for baseline was determined by averaging the 7 daily WI-NRS scores before Day 1 (i.e., Days -7 to -1) for all by-visit summaries. The by-visit WI-NRS score for post-baseline visits was determined by averaging the 7 daily WI-NRS scores before the visit day. Participants with missing Week 12 data for any reason, including treatment discontinuation (due to development of atopic dermatitis lesions or any other cause), were defined as nonresponders.

Time to Relapse (Defined as <F-VASI75)
from Week 52 (first visit of this Treatment Extension study) to Week 104 (end of treatment in this Treatment Extension study)

Relapse was defined as a loss of 75% improvement from Baseline in the Face Vitiligo Area Scoring Index score (F-VASI75) response, assessed as percentage improvement in the F-VASI score at Baseline (Day 1 of the parent study) to \<75%.

Number of Participants With Investigator Global Assessment of 0 or 1 at Week 4

Number of Participants with Investigator Global Assessment of 0 or 1 at Week 4 IGA Scale from 0-4 Clear 0 No signs of SD Almost Clear 1 Just perceptible erythema and just perceptible scaling Mild 2 Mild erythema and mild scaling Moderate 3 Moderate erythema and moderate scaling Severe 4 Severe erythema and severe scaling

Complete healing of target ulcer
Up to 24 weeks

The proportion of patients with complete re-epithelization, defined as 100% re-epithelialization without any drainage, of the target ulcer at week 24.

Change From Baseline in Total Body Vitiligo Area Scoring Index (T-VASI) at Week 48
Baseline; 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).

Percentage Change From Baseline in Chemokine (C-X-C Motif) Ligand 10 (CXCL10), an Immune Biomarker, at Week 4, Week 12, and Week 24
Baseline; Week 4, Week 12, and Week 24

Baseline was defined as the last non-missing measurement obtained on or before the first application of study drug. Percentage change from Baseline was calculated as the (\[post-Baseline value minus the Baseline value\] / Baseline value)\*100.

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
Baseline; 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).

Number of participants with Treatment-emergent Adverse Events (TEAEs)
Up to 16 weeks, including 30 days of safety follow-up

Defined as adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug.

Number of participants with TEAEs leading to dose interruption or discontinuation
Up to 16 weeks, including 30 days of safety follow-up

Number of participants with TEAEs leading to dose interruption or discontinuation.
