A Study To Assess Adverse Events and Effectiveness of Upadacitinib Oral Tablets in Adult and Adolescent Participants With Vitiligo

Vitiligo is a common chronic autoimmune disease that causes the body's immune system to attack its own pigment producing skin cells. This study is to evaluate how safe and effective upadacitinib is in participants with non-segmental vitiligo (NSV). Adverse effects and change in disease activity will be assessed.

Upadacitinib is currently being investigated for the treatment of NSV. There will be 2 replicate studies running at the same time (Study 1 and Study 2 with periods A and B), an optional exploratory NB-UVB phototherapy study (Study 3), and a re-randomized dose-escalation study (Study 4). In Period A, participants are placed in 1 of 2 groups called treatment arms. Each group receives a different treatment. There is a 1 in 3 chance that participants will receive placebo. In Period B, all participants will receive upadacitinib. Approximately 540 adult and adolescent participants with NSV will be enrolled between each main study at around 180 sites worldwide with an option for adult participants who completed Period A of either study and did not achieve T-VASI90 at week 48 while on study drug, to enter Study 3. Participants who failed to achieve T-VASI75 response at week 118 of Study 1 or 2 or at week 70 of Study 3 will be considered for entry into Study 4.

In Studies 1 and 2: Period A, participants will receive oral tablets of upadacitinib or placebo once a day for 48 weeks. In Period B, participants will receive oral tablets of upadacitinib 15 mg once a day for 112 weeks. Participants will be followed up for 30 days. Study 3 participants will receive upadacitinib monotherapy or upadacitinib with Narrow-Band Ultraviolet B (NB-UBV) phototherapy for at least 24 weeks followed by upadacitinib alone. In Study 4, participants will be re-randomized to receive oral tablets of upadacitinib 15 mg or 30 mg once a day for 56 weeks.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Primary outcomes

  1. Percentage of Participants Achieving Total Vitiligo Area Scoring Index (T-VASI) 50 (≥ 50% Improvement in T-VASI From Baseline)

    Time frame: Week 48

    The vitiligo area scoring index (VASI) is a validated scoring method used to assess the areas of depigmentation due to vitiligo. It is based on a composite estimate of the overall area of vitiligo patches, measured by the number of hand units (palm plus 5 digits = 1% body surface area [BSA]) multiplied by the degree of depigmentation within each affected area (0%, 10%, 25%, 50%, 75%, 90%, or 100%). The T-VASI is calculated using a formula that includes contributions from all body regions, with a possible range from 0 to 100.

  2. Percentage of Participants Achieving Facial-Vitiligo Area Scoring Index (F-VASI) 75 (≥ 75% Improvement in F-VASI From Baseline)

    Time frame: Week 48

    The vitiligo area scoring index (VASI) is a validated scoring method used to assess the areas of depigmentation due to vitiligo. The F-VASI includes contributions from the face, with a possible range from 0 to 3.

    Time frame: Study 4 Week 28

    The vitiligo area scoring index (VASI) is a validated scoring method used to assess the areas of depigmentation due to vitiligo.
