The study is being conducted to learn more about rocatinlimab in people with AD. It will see if rocatinlimab is effective to treat people with AD and whether it causes side effects. It will also help to establish the beneficial impact of the study treatment with rocatinlimab on the related outcomes including skin itching, skin pain, sleep loss, and impaired quality of life in people with AD. The study duration will last a maximum of 68 weeks (about 1 year 3 months), including a screening period of minimum of 8 days and up to 30 days, a 52-week study treatment period, and a safety follow-up (SFU) visit 16 weeks after the last dose of study drug in case you do not continue into the long-term maintenance study.

This project is a pilot study to determine if use of the J-Tip Needle-Free Injection System, used to administer local anesthesia, has any effects on the appearance of skin samples when viewed under a microscope compared with skin samples that have been injected with local anesthesia using a needle. If use of the J-Tip device for local anesthesia delivery is shown not to alter the microscopic appearance of skin, anesthesia for skin biopsies in the future may potentially be performed without a needle, allowing for less fear and pain.

Patients between 4-21 years of age with at least one wart or molluscum lesion are eligible to participate in this study. The duration of the study is a minimum of 4 weeks with the maximum duration of monthly treatments for one year, depending on lesion clearance. The number of lesions will be chosen by the dermatologist. Patients who opt to participate will receive non-thermal, or cold, atmospheric plasma to treat all lesions selected. Safety profile as well as changes in size, pain and appearance will be measured. Photographs and dermatologist impressions will be used to measure treatment response.

This Phase 3 study is designed to assess the long-term safety and efficacy of lebrikizumab in participants 6 months to <18 years of age with moderate-to-severe AD. Participants who have completed Study KGBI through Week 16 without requiring the use of systemic rescue medication will be eligible to enroll into Study KGBJ. All participants will receive active lebrikizumab treatment during Study KGBJ. The planned duration of treatment for each participant is approximately 52 weeks. All participants will enter a post-treatment safety follow-up period approximately 12 weeks after the last dose of lebrikizumab. This study will include both on-site (in clinic) and remote visits (telephone calls).

The purpose of this research study is to determine if an investigational cream, ruxolitinib 1.5% cream, is safe and effective to treat adults with prurigo nodularis. In this study, ruxolitinib cream will be compared to a "vehicle cream." The vehicle cream looks like the ruxolitinib cream but contains no ruxolitinib. This study can last up to 60 weeks, including up to 4 weeks for screening, up to 52 weeks for treatment, and 30 days for safety follow-up. Eligible participants will be randomized 1:1 to receive ruxolitinib 1.5% cream or vehicle cream for the first 12 weeks. For the following 40 weeks all participants will receive the ruxolitinib cream.

This is an international, Phase IIb/III multi-center, double-blind, placebo-controlled, randomised trial assessing the efficacy and safety of spesolimab versus placebo in patients with moderate to severe HS. Approximately 200 trial participants in Part 1 (Phase IIb) and 260 trial participants in Part 2 (Phase III) will be randomised. For Part 1, after signing the informed consent, trial participants will enter the screening period for up to 28 days, and if all eligibility criteria are met, trial participants will be randomised in a 1:1:1:1 ratio to either active group, including high dose, medium dose, and low dose group, or placebo group. Once randomised, trial participants will start a treatment period of 50 weeks. Administration of treatment will be up to Week 48.

This is a multi-center, randomized, double-blind, placebo-controlled, phase II/III study to evaluate the efficacy and safety of spesolimab compared to placebo in the treatment of Netherton syndrome. This study will last up to 72 weeks with 16 clinic visits. Eligible patients will be randomized 2:1 to receive either spesolimab i.v. loading doses at Week 0 plus spesolimab subcutaneous doses every 4 weeks, or to receive placebo i.v. loading dose at Week 0 plus placebo subcutaneous doses every 4 weeks. At Week 20, all patients will enter the open label period to receive spesolimab subcutaneous dose every 4 weeks up to Week 52. There will be a safety follow up visit 16 weeks after the last dose.

This is a Phase 3, placebo-controlled, randomized, double-blind research study evaluating the efficacy, safety, and PK of baricitinib in children from 6 years to less than 18 years of age with severe alopecia areata. 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 posttreatment follow-up period. If the subject meets all eligibility criteria they will be randomized to receive either baricitinib high dose, baricitinib low dose, or placebo for 36 weeks. Participants will then be transitioned into the long-term extension treatment period. Subjects will attend 18 clinic visits for up to 145 weeks.

The study is being conducted in order to assess the long-term safety of rocatinlimab in adult and adolescent subjects with moderate-to-severe atopic dermatitis (AD). The study population will include subjects who completed an end of treatment duration visit in a parent study and meet eligibility criteria. Subjects will be randomized to receive a dosage of rocatinlimab based on age and their previous dosage from the parent study. The total duration of participation, including the parent study, will be up to 2.5 to 3 years, with a safety follow-up period after the last dose of investigational product at week 104.

This study is being done to learn more about apremilast (AMG 407) in mild to moderate plaque psoriasis in participants (children and adolescents) aged 6 to 17 years. It will see whether it causes any side effects. About 50 people are expected to take part in this study. The duration of the study is approximately 285 days. This includes 3 phases: 35 days of screening phase, 225 days (32 weeks) of treatment phase, and 60 days of observational follow-up phase after the last dose of study drug – this means drug is still being tested to see if it is safe and works.
