Eligibility Criteria
You may qualify if:
- 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:
- 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.
- +3 more criteria
You may not qualify if:
- 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 behavior or recurrent suicidal behavior. For adolescents, any previous lifetime history of suicidal behavior.
- Medical conditions pertaining to vitiligo and other diseases/conditions affecting the skin:
- Currently have active forms of other disorders of pigmentation (including but not limited to Vogt-Koyanagi-Harada disease, malignancy-induced hypopigmentation \[melanoma and mycosis fungoides\], post-inflammatory hypopigmentation, pityriasis alba \[minor manifestation of atopic dermatitis\], senile leukoderma \[age-related depigmentation\], chemical/drug-induced leukoderma, ataxia telangiectasia, tuberous sclerosis, melasma (all types, including mixed), and congenital hypopigmentation disorder including piebaldism, Waardenburg syndrome, hypomelanosis of Ito, incontinentia pigmenti, dyschromatosis symmetrica hereditarian, xeroderma pigmentosum, and nevus depigmentosus). NOTE: Coexistence of halo nevus/nevi (also known as Sutton nevus/nevi) is permitted.
- Currently have active forms of inflammatory skin disease(s) or evidence of skin conditions (for example, morphea, discoid lupus, leprosy, syphilis, psoriasis, seborrheic dermatitis) at the time of the Screening or Baseline Visit that in the opinion of the investigator would interfere with evaluation of vitiligo or response to treatment.
- Leukotrichia in more than 33% of the face surface area affected with vitiligo lesions OR leukotrichia in more than 33% of the total body surface area affected with vitiligo lesions.
- Have a superficial skin infections within 2 weeks prior to first dose on Day 1. NOTE: participants may be rescreened after the infection resolves.
- General Infection History:
- Having a history of systemic infection requiring hospitalization, parenteral antimicrobial, antiviral (including biologic treatment), antiparasitic, antiprotozoal, or antifungal therapy, or as otherwise judged clinically significant by the investigator within 6 months prior to Day 1.
- Have active acute or chronic infection requiring treatment with oral antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 4 weeks prior to Day 1. NOTE: participants may be rescreened after the infection resolves.
- Evidence or history of untreated, currently treated or inadequately treated active or latent infection with Mycobacterium TB
- Specific Viral Infection History:
- History (single episode) of disseminated herpes zoster or disseminated herpes simplex, or a recurrent (more than one episode of) localized, dermatomal herpes zoster.
