Pimecrolimus

The primary objective of the trial is to evaluate the safety of TEV-53408 administered subcutaneously for the treatment of adults with vitiligo. A secondary objective is to further evaluate the safety of TEV-53408. The planned study period per participant is 84 weeks including a screening period (up to 4 weeks), a 24-week open-label treatment period, a 16-week washout period, and a 40-week follow-up period.

This is a multi-center, parallel-group, open-label, randomized, Phase 1b study to explore the safety, clinical activity, pharmacokinetics and pharmacodynamics of DR-01 in adults with Alopecia Areata or Vitiligo.

This study is to evaluate how safe and effective ritlecitinib is in participants with non-segmental vitiligo (NSV). Ritlecitinib is studied in patients with non-segmental vitiligo. Vitiligo is a chronic acquired depigmentation disorder characterized by well-defined pale white patches of skin. Non-segmental vitiligo is an autoimmune disorder and is the focus of this study. The study will show: * if the repigmentation (the recovery of pigmentation) achieved in study B7981040 (also called the "parent study") will stay the same or will further increase if you keep receiving the same study medicine (ritlecitinib 50 milligrams or placebo) * Or if more repigmentation can be achieved if you start receiving ritlecitinib 100 milligrams in this study * Or how long the repigmentation achieved during the parent study lasts if you start receiving placebo in this study. This study is seeking for participants who: * have non-segmental vitiligo (either active or stable) and * received ritlecitinib or placebo for 52 weeks in the parent study. A placebo looks exactly like the study capsule but does not contain any medicine in it. All participants in this study will receive the study medicine or placebo. The study medicine (ritlecitinib 50 milligrams or 100 milligrams) or placebo are capsules that are taken by mouth at home every day. On study visit days, you must take the medication at the study site, and not at home. Participants may receive the study medicine or placebo for up to 52 weeks. The study will look at the experiences of people receiving the study medicine. This will help see if ritlecitinib is better for treating vitiligo. Participants will be involved in this study for a maximum of 60 weeks. During this time, they will have 9 study visits during the study. Ritlecitinib 50 mg is an approved drug for the treatment of severe Alopecia Areata (a disease with similar abnormal changes in the body functions like vitiligo) in the US, EU and Japan. China, Great Britain and other market applications are pending.

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 an approved drug for various immune-mediated inflammatory diseases and 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) and an optional exploratory Narrow-Band Ultraviolet B (NB-UVB) phototherapy study (Study 3). 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 and 2 in 3 chance participants will receive upadacitinib. In Period B, all participants will receive upadacitinib. Approximately 270 adult and adolescent participants with NSV will be enrolled in each main study ((Study 1 and Study 2, 540 subjects total) at approximately 90 sites worldwide with an option for adult participants who completed Period A of either study and did not achieve T-VASI 90 at week 48 while on study drug, to enter Study 3. 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 NB-UBV phototherapy for at least 24 weeks followed by upadacitinib alone. 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.

This trial is testing a medication called ritlecitinib, which is taken as oral capsules. It aims to help adults and adolescents who have non-segmental vitiligo, a condition that causes skin to lose its color. The medication works by managing the immune system to stop the skin from losing its color.

This trial tests if a daily cream with rapamycin can help treat vitiligo, a skin condition causing color loss. Participants will use the cream on one side of their body and a different cream on the other for several months. The study will also check patient satisfaction and any side effects. Rapamycin has been studied for its potential to stabilize cyst growth in ADPKD, but larger trials showed no benefit on kidney function.
