J2T-MC-B002 (B002) examines the effectiveness of lebrikizumab in treating moderate-to-severe atopic dermatitis (AD). This study involves adult and adolescent patients suffering from eczema, which is characterized by inflammation, redness, and irritation of the skin. Participants will complete symptom assessments during their visits and will schedule appointments within specific timeframes. The study will also observe skin lesions using clinical measures. Participants will remain in the study for up to two years, even if their therapies change, to track disease progression with or without lebrikizumab. This observational study aims to record real-world treatment outcomes for the analysis of lebrikizumab in AD therapy.

This study aims to evaluate the safety and tolerability of ARQ-151 cream 0.05% in infants with mild to moderate eczema after daily application for four weeks. ARQ-151 contains the active ingredient roflumilast, which reduces the activity of the enzyme PDE-4 involved in inflammation. Since eczema is an inflammatory skin disease, ARQ-151 could potentially help treat this condition.

An international research registry called the CorEvitas International Adolescent Alopecia Areata (AA) Registry (the "CorEvitas Registry"). This observational registry studies adolescent patients with AA between 12-17 years of age under the care of a dermatology provider diagnosed with moderate to severe alopecia areata.

An international research registry called the CorEvitas International Adolescent Atopic Dermatitis (AD) Registry (the "CorEvitas Registry"). This observational registry studies adolescent patients with AA between 12-17 years of age under the care of a dermatology provider diagnosed with moderate to severe atopic dermatitis.

This study aims to evaluate the effectiveness of ruxolitinib cream compared to a placebo (vehicle) cream in treating vitiligo in children aged 2 to 12 years. The vehicle cream looks identical to the ruxolitinib cream but contains no active medication. By comparing these two treatments, researchers hope to determine whether ruxolitinib is more effective than the placebo in improving facial and body vitiligo symptoms. This study could provide important insights into new treatment options for young children affected by this condition.

Ritlecitinib (PF 06651600) is an investigational drug (referred to as "study drug" from here on) and is being developed as possible study treatment for participants with non segmental vitiligo (both active and stable vitiligo). The study drug will be compared with a placebo to find out if the study drug is better than the placebo for the study treatment of vitiligo. After a screening period of up to 30 days, approximately 1000 eligible participants (Part Ia) will be randomized in a 3:1:1 ratio to ritlecitinib 100 mg QD (600 participants), ritlecitinib 50mg QD (200 participants), and placebo (200 participants) in the 52-week placebo-controlled treatment period. At Week 52, based how patients respond to the study drug will enter the 52 week extension period.

M1095-HS-304 is a Phase 3, open-label, single-arm design that assesses the safety and tolerability of sonelokimab in adolescent patients with HS. The study population will comprise adolescent participants (aged ≥12 to ≤17 years) with moderate to severe HS.

The research study determines if remibrutinib (study treatment) with two doses, dose A (10 mg b.i.d.) and dose B (25 mg b.i.d)., is safe and effective and can help adult patients with moderate to severe hidradenitis suppurativa (HS).

This is a Phase 3, multinational, multicenter, randomized, double-blind, placebo-controlled, parallel-group, 3-arm, multiple dose level study to investigate the efficacy and safety of subcutaneous injections of amlitelimab in participants aged 12 years and older with moderate-to-severe AD who are on background topical corticosteroids or calcineurin inhibitors and have had an inadequate response to prior biologic or oral JAKi therapy. There will be up to 13 visits including up to a 4-week screening period, a 36 week treatment period, and a post-treatment safety follow up period or a long-term Safety Study for 16 weeks. Subjects will be randomized in a 1:1:1 ratio to the following study arms: amlitelimab Q4W, amlitelimab Q12W, and placebo Q4W.

This is a Phase 3, multicenter, randomized, parallel-group, double-blind, placebo-controlled study to evaluate the efficacy and safety of sonelokimab in adults with moderate to severe HS. Following a Screening Period of up to 28 days, each participant will enter a Placebo-controlled Period of 16 weeks (Part A) and subsequently a Crossover/Maintenance Period of 36 weeks (Part B). In Part A subjects will be randomly assigned in a 2:1 ratio to sonelokimab 120 mg or placebo. In Part B, participants who were initially randomized to placebo will cross over to sonelokimab and will receive this treatment for the remainder of the study. An End of Treatment (EOT) Visit will be performed at Week 52. After the EOT Visit, all participants who complete Week 52 will be offered the opportunity to enter an optional long-term open label extension (OLE) study under a separate protocol. For participants who do not progress to the OLE study, a Safety Follow-up Visit will be required 8 weeks after the last dose of study treatment.
