入选标准
- •Participants must be ≥18 years of age at Screening.
- •Eligible participants must have at both Screening and BL: • A clinical diagnosis of nonsegmental vitiligo for at least 3 months; and • Body surface area (BSA) involvement between 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 and T-VASI ≥3; and • Either active or stable nonsegmental vitiligo at both Screening and BL visits. All participants who do not have the features of active vitiligo (defined below) will be classified as having stable disease.
排除标准
- •Medical conditions pertaining to vitiligo and other diseases/conditions affecting the skin
- •History of severe allergic or anaphylactoid reaction to any kinase inhibitor or a known allergy/hypersensitivity to any component (including excipients) of the study intervention.
