Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants Treated With Ruxolitinib Cream Who Achieve a ≥ 50% Improvement in Facial Assessment of the Vitiligo Area and Severity Index Score (F-VASI50) Compared With Participants Treated With Vehicle [ Time Frame: Week 24 ]
    F-VASI is the percentage of depigmented vitiligo skin expressed as a percentage of the total area of skin on the face (100%) and estimated by the investigator using the palmar method.


Secondary Outcome Measures :
  1. Percentage of Participants Who Achieve a Facial Assessment of the Physician's Global Vitiligo Assessment (F-PhGVA) of Clear or Almost Clear [ Time Frame: Week 24 ]
    F-PhGVA has a 5-point scale (clear, almost clear, mild disease, moderate disease, and severe disease) assessed by the physician to determine the severity of vitiligo and will be reported for face and overall. Complete facial repigmentation is defined as an F-PhGVA of clear (0).

  2. Percentage of Participants Who Achieve a ≥ 50% Improvement From Baseline in Full Body Assessment of Vitiligo Area and Severity Index (T-VASI) [ Time Frame: Week 52 ]
    T-VASI is calculated using a formula that includes contributions from all body regions (possible range, 0-100). The body is divided into 6 separate and mutually exclusive sites (head/neck, hands, upper extremities [excluding hands], trunk, lower extremities [excluding feet], and feet), with percentage of vitiligo involvement estimated in hand units by the same investigator throughout the study.

  3. Safety and Tolerability Assessed by Monitoring the Frequency, Duration, and Severity of Adverse Events (AEs) [ Time Frame: up to 156 weeks ]
    AE is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related, that occurs after a subject provides informed consent. Abnormal laboratory values or test results occurring after informed consent constitute AEs only if they induce clinical signs or symptoms, are considered clinically meaningful, require therapy, or require changes in the study drug.

  4. Dose Response on Percentage Change From Baseline in F-VASI [ Time Frame: up to 156 weeks ]
  5. Mean and Percentage Change From Baseline in F-VASI Score During the Treatment Periods. [ Time Frame: up to 156 weeks ]
  6. Percentage of Subjects Who Achieve an F-VASI50 [ Time Frame: up to 156 weeks ]
  7. Percentage Change From Baseline in F-BSA Repigmentation [ Time Frame: up to 156 weeks ]
  8. Percentage Change From Baseline in T-BSA Repigmentation [ Time Frame: up to 156 weeks ]
  9. Mean and Percentage Change From Baseline in T-VASI Score [ Time Frame: up to 156 weeks ]
  10. Mean and Percentage Change From Baseline in VETF [ Time Frame: up to 156 weeks ]
  11. Percentage of Subjects in Each F-PhGVA and T-PhGVA Category During the Treatment Periods [ Time Frame: up to 156 weeks ]
  12. Percentage of Subjects in Each F-PaGVA and T-PaGVA Category During the Treatment Periods [ Time Frame: up to 156 weeks ]
  13. Percentage of Subjects in Each PaGIC-V Category During the Treatment Periods [ Time Frame: up to 156 weeks ]
  14. Proportion of Subjects Who Report PaGIC-V of Very Much Improved or Much Improved [ Time Frame: up to 156 weeks ]
  15. Times to Achieve an F-VASI50 and T-VASI50 [ Time Frame: up to 156 weeks ]
  16. Times to Achieve an F-PhGVA and T-PhGVA of Clear or Almost Clear [ Time Frame: up to 156 weeks ]
  17. Time to Achieve a PaGIC-V of Very Much Improved or Much Improved [ Time Frame: up to 156 weeks ]

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Clinical diagnosis of vitiligo.

  • Vitiligo with depigmented areas including:

    • 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.
