The primary purpose of this study is to assess the efficacy and safety of ruxolitinib 1.5% cream applied twice daily in participants with mild to moderate HS (Hurley Stage I or II) without draining tunnels.

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.

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.

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 study is being conducted at approximately 150 research centers worldwide and is expected to enroll approximately 675 pediatric subjects in total with moderately to severely AD. This study will have 2 cohorts, a Randomized Cohort, and a Dupilumab-Inadequate Responder / Dupilumab Medically Inadvisable Cohort. The study comprises a 35-day Screening Period; a 16-week, open-label, efficacy assessor blinded study treatment period for the subjects in the randomized cohort; an open-label period up to Week 160 for subjects in the upadacitinib study treatment arms across both cohorts (Randomized Cohort and Dupi-IR/Dupilumab Medically Inadvisable Cohort); an open label period up to Week 52 for subjects in the dupilumab arm; and a 30-day Follow up Visit/call after the last dose is administered for upadacitinib or dupilumab.

This is a global, Phase 3b/4, randomized, open-label, efficacy assessor-blinded, multi-center study that will evaluate upadacitinib compared to dupilumab in adult subjects with moderate to severe AD and inadequate response to dupilumab after at least 6 months of current use. The study consists of a 35-day Screening Period; an 8-week randomized, open-label, efficacy assessor blinded treatment period for all participants (Period 1); a 24-week open-label, efficacy assessor-blinded extension period for all participants who finish Period 1 (Period 2) (total duration of Period 1 and Period 2 is 32 weeks); and a 30-day Follow-up visit.
