The percentage of BSA (hand or thumb unit) vitiligo involvement was estimated to the nearest 0.1% by the Investigator. F-VASI has a possible range from 0 to 3.5, with higher scores indicating more severe disease. Participants missing the F-VASI assessment at Week 24 are imputed as F-VASI35 non-responders. |

| Secondary | Change From Baseline in the Vitiligo Extent Score (VES) at Weeks 12, 24, 36, 48 | Baseline; Weeks 12, 24, 36, and 48 | The Vitiligo Extent Score (VES) is a tool for measuring the total body surface area affected by vitiligo. Images are shown of varying extent of vitiligo lesions from least to greatest extent over different body locations. An image from each body location is selected by the investigator during the patient encounter that best reflects the extent to which vitiligo lesions are covering the body surface area (BSA). If lesions are covering an area larger than shown in the last photo, a \>75% but \<100% option can be selected. The online calculator at www.vitiligo-calculator.com will then use selected images to calculate the percentage of the body surface area involved or grade of extent per region (Grade 0 to 6). The VES has a possible range from 0 to 100, with higher scores indicating more severe disease. A negative change from Baseline in the VES signifies improvement. Only participants with available data were analyzed. |

The response to each question will be scored on a 0 (not at all) to 6 (all of the time) scale. The VitiQoL score is calculated as the sum of questions 1 through 15, providing a possible range from 0 to 90, with higher scores indicating more severe disease. A negative change from Baseline in the VitiQoL signifies improvement. Only participants with available data were analyzed. |
| Secondary | Proportion of Participants in Each Vitiligo Noticeability Scale (VNS) Category at Weeks 12, 24, 36, 48 | Weeks 12, 24, 36, and 48 | The Vitiligo Noticeability Scale (VNS) is a validated patient-reported outcome measure of vitiligo treatment where participants will be presented with one pre-treatment photograph of their face and asked to answer the question: "Compared with before treatment, how noticeable is the vitiligo now?". The same pre-treatment photograph must be used at each visit. Scores range from 1 to 5 with a score of 1 being "More noticeable", 2 "As noticeable", 3 "Slightly less noticeable", 4 "A lot less noticeable", and 5 "No longer noticeable". Only participants with available data were analyzed. |

Lower scores represent lesser extent and lesser severity; higher scores represent greater extent and greater severity. A score of 0 represents clear skin, with no loss of pigmentation after a natural light or Woods lamp examination and a score of 4 represents severe vitiligo, with extensive loss of pigmentation affecting most areas of the body. Only participants with available data were analyzed. |
