The main objective of the study is to evaluate the efficacy of twice daily applications of delgocitinib cream 20 mg/g compared with cream vehicle in the treatment of adult participants with mild to severe palmoplantar pustulosis (PPP). Total study duration for each participants will be approximately 18 weeks, for an approximate total of 9 visits.

Litifilimab is a humanized immunoglobulin G1 (IgG1) monoclonal antibody targeting blood dendritic cell antigen 2. It is an inhibitory receptor expressed on the surface of human plasmacytoid dendritic cell (pDCs) and is being investigated for the potential treatment of systemic lupus erythematosus and cutaneous lupus erythematosus. The primary objectives of the study are to evaluate the efficacy of litifilimab compared with placebo in reducing skin disease activity measured by the CLA-IGA-R score \[Parts A\] and the Cutaneous Lupus Erythematosus Disease Area and Severity Index Activity (CLASI-A) score \[Part B\] in participants with active SCLE and/or CCLE with or without systemic manifestations and refractory and/or intolerant to antimalarials. The secondary objectives of the study are to evaluate the efficacy of litifilimab in reducing SCLE and/or CCLE disease activity by CLA-IGA-R, CLASI-A; to evaluate additional efficacy parameters of litifilimab in reducing SCLE and/or CCLE disease activity; safety; tolerability; and immunogenicity of litifilimab \[Parts A and B\].

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.

The main aim of this study is to see how well the medicine zasocitinib works, how safe it is, and how children and teenagers aged 4 to under 18 with moderate-to-severe plaque psoriasis respond to it. The study will be done in 2 parts: Part A will include both children and teenagers, while part B will only include children. At first, only teenagers who meet the study rules can participate in this study. Children may only start to participate once enough information has been collected from other studies with zasocitinib. Participants in Part A will initially be assigned to receive either zasocitinib or placebo for the first 16 weeks of treatment, then all participants will receive zasocitinib through the end of the study. All participants in Part B will be assigned to receive treatment with zasocitinib throughout the study. Participants will be in the study for up to 4 years and 2 months (217 weeks), including up to 35 days for the screening period, 208 weeks of treatment (Part A and Part B) and a 4-week safety follow-up period. During the study, participants will visit their study site multiple times.

The total duration of the study is 76 weeks and consists of: Screening (up to 4 weeks), Treatment Period 1 (16 weeks, double-blind treatment with remibrutinib (Dose A or Dose B) or placebo, Treatment Period 2 (52 weeks, treatment with remibrutinib (Dose A or Dose B) and Safety Follow-Up (treatment-free follow-up for 4 weeks). Participants who prematurely discontinue study treatment (either during Treatment Period 1 or Treatment Period 2) are encouraged to remain in the study. Participants who do not wish to remain in the study will enter a 4-week Safety Follow-Up period.

The main purpose of this study is to determine the efficacy and safety of baricitinib for the treatment of severe or very severe alopecia areata (hair loss) in children from 6 years to less than 18 years of age. The study is divided into 4 periods, a 5-week Screening period, a 36-week Double-Blind Treatment Period, an approximately 2-year Long-term Extension Period, and a 4-week Post-treatment Follow-up period.

This phase 2b study is designed to evaluate the safety and efficacy of KT-621 in adult and adolescent participants with moderate-to-severe atopic dermatitis (AD), a common form of eczema. The main goals of this study are to learn how effective KT-621 is at reducing the severity and extent of AD, the safety and tolerability of KT-621, how KT-621 behaves in the body, and how the body responds to KT-621. This is a 16-week double-blind, placebo-controlled study with a 52-week open-label period.

Hidradenitis Suppurativa (HS) is a skin condition that causes deep, painful bumps on the skin. These bumps usually appear in an area where the skin rubs together. They start as small bumps but may become swollen and red over time. If they fill with pus, these lumps are called abscesses; these can also burst. Over time, the area can get scars and tunnels on or under the skin. Recent studies suggest that the condition may start when hair follicles become damaged and blocked. This impacts the skin and may activate the body's germ-fighting (immune) system. This allows bacteria to grow on the skin which worsens the condition and can cause abscesses. The main aims of this study are to learn how safe zasocitinib is, how well it works and how well adults with HS tolerate it compared with a placebo. The participants will receive the study treatment (either zasocitinib or placebo) for up to 4 months (16 weeks). The placebo looks like the zasocitinib capsule but does not have any medicine in it. After the first 4 months, all participants (also those who initially received placebo) will then receive zasocitinib for up to 8 months (36 weeks). During the study, participants will visit their study clinic 12 times.

Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects the joints and skin in people who have psoriasis (PsO). The main aim of the study is to know how well zasocitinib (TAK-279) works in participants with active PsA who have not previously been treated with biologic disease-modifying antirheumatic drugs. The participants will be treated with either zasocitinib, active comparator, or placebo. Participants will be in the study for up to 60 weeks.

Atopic dermatitis (AD) is a skin condition that may cause a rash and itching due to inflammation of the skin. Topical therapies applied over the skin may not be enough to control the AD in trial participants who require systemic anti-inflammatory treatment. This study compares upadacitinib to dupilumab in pediatric participants with moderate to severe AD who are candidates for systemic therapy. Adverse events and change in the disease activity will be assessed. Upadacitinib is an approved drug for treating AD patients aged 12 or older. Participants will receive upadacitinib (given as daily dose) or dupilumab (given at label indicated dose every 2 or 4 weeks). Participants will be stratified depending on disease severity, age and response to previous treatment. There is 1 in 5 chance for participants to receive dupilumab during the randomized cohort. Approximately 675 participants aged 2 to less than 12 years of age will be enrolled in this study at approximately 150 sites worldwide. The study population (As defined by participants age or prior treatment) to be enrolled in the study is dependent on local regulatory requirement and/or agreement. Participants will receive upadacitinib oral tablets once daily (or oral solution twice a day) for 160 weeks, or dupilumab as per its label for 52 weeks, and followed for 30 days after the last dose of upadacitinib and at least 12 weeks after the last dose of dupilumab. 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 clinical assessments, blood tests, checking for side effects and completing questionnaires.
