Ages Eligible for Study:   12 Years and older   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Participants ≥18 years of age at Screening. Adolescents (12 to <18 years of age) are also eligible for this study, but only if approved by the local IRB/EC and regulatory health authority. Where these approvals have not been granted, only participants ≥18 years of age will be enrolled.

    Disease Characteristics:

  2. Eligible participants must have at both Screening and Baseline:

    • A clinical diagnosis of nonsegmental vitiligo for at least 3 months; and
    • BSA involvement 4%-60% inclusive, excluding involvements at palms of the hands, soles of the feet, or dorsal aspect of the feet; and
    • BSA ≥0.5% involvement on the face (face is defined as including the area on the forehead to the original hairline, on the cheek vertically to the jawline, and laterally from the corner of the mouth to the tragus. The face will not include scalp, ears, neck, or surface area of the lips, but will include the nose and the eyelids; and
    • F-VASI ≥0.5 & T-VASI ≥3; and
    • Either active or stable disease nonsegmental vitiligo at both Screening and Baseline visits. All participants who do not have the features of active vitiligo (defined below) are required to have stable disease.

    Active vitiligo is defined as:

    • Participants will be classified as having active vitiligo based on the presence of at least one active lesion at baseline defined as one of the following:
    • New/extending lesion(s) in the 3 months prior to Screening visit (confirmed by photographs or medical record):
    • Confetti-like lesion(s); Confetti-like depigmentation is characterized by the presence of numerous 1-mm to 5-mm depigmented macules in clusters;
    • Trichrome lesion(s);Trichrome lesions have a hypopigmented zone of varying width between normal and completely depigmented skin, resulting in 3 different hues of skin;
    • Koebner phenomenon/phenomena (excluding Type 1 [history based on isomorphic reaction]). The Koebner phenomenon manifests as depigmentation at sites of trauma, usually in a linear arrangement.

    Stable vitiligo is defined as an absence of signs of active disease. All participants who do not have the features of active vitiligo (defined above) are required to have stable disease.

    Eligibility is determined at Screening and Baseline based on the resulting scores from the local in-person reads of F-VASI, T-VASI, and BSA.

    Other Inclusion Criteria:

  3. If receiving concomitant medications for any reason other than vitiligo, participant must be on a stable regimen, which is defined as not starting a new drug or changing dosage within 7 days or 5 half-lives (whichever is longer) prior to Day 1. Participant must be willing to stay on a stable regimen during the duration of the study.
  4. Must agree to stop all other treatments for vitiligo from Screening through the final follow-up visit.

Exclusion Criteria:

  1. Any psychiatric condition including recent or active suicidal ideation or behavior that meets any of the following criteria:

    • Suicidal ideation associated with actual intent and a method or plan in the past year: "Yes" answers on items 4 or 5 of the C-SSRS administered at the screening visit.
    • Previous history of suicidal behaviors in the past 5 years: "Yes" answer (for events that occurred in the past 5 years) to any of the suicidal behavior items of the C-SSRS.
    • For adults, any lifetime history of serious suicidal ideation or behavior or recurrent suicidal behavior. For adolescents, any previous lifetime history of suicidal behavior.
  2. Medical conditions pertaining to vitiligo and other diseases/conditions affecting the skin:
