The purpose of this study is to evaluate the efficacy of eltrekibart compared to placebo in adults with moderate to severe HS. The study duration will be up to 67 weeks. This study includes a screening period, a 16-week double-blind, placebo-controlled treatment period, a 36-week double-blind maintenance treatment period, and a 10-week follow-up period.

The purpose of this study is to evaluate the efficacy and safety of upadicitinib in adults and adolescents with severe alopecia areata. Participation in this research study will take approximately 168 weeks with 17 visits in that time. This research study includes three phases; a screening phase, treatment phase, and a follow-up phase. The length of the screening period varies from 1 to 35 days, depending on therapies that must be washed out or discontinued before initiation of treatment. Patients who meet all eligibility criteria will be randomized to receive upadicitinib or placebo for the first 24 weeks. At week 24, all patients will receive upadicitinib until week 160. The post-treatment follow-up visit will occur approximately 30 days after the last study drug dose.

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.

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 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).

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.

In clinical practice, standard of care for treatment of adolescent acne includes extended courses, i.e., 3 months or longer, of systemic tetracyclines, a type of antibiotic.The gut is home to many bacteria. Administration of antibiotics kills these bacteria and prevents them from repopulating during critical developmental periods. The lack of these bacteria has effects on metabolism, fat, and bone mass
accrual in adolescent mice. Given what we have observed in mouse studies,
we are interested to observe the impact of systemic tetracycline acne therapy in adolescents on fat deposition and the skeleton.

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. The duration of this study is a maximum of 60 weeks. There will be an initial screening period of 30 days where the study doctor will determine eligibility. If eligible, participants will be randomly assigned to receive the study drug or a placebo during a 52 week study treatment period. At the end of the treatment period, participants will enter a 4 week Follow Up Period.

The purpose of this study is to assess the dose dependent safety, tolerability and potential efficacy of QRX003 lotion in subjects with Netherton Syndrome (NS). This is a multi-center, randomized, vehicle-controlled, double-blind, parallel group comparison study of QRX003 lotion in adult subjects 18 years of age or older with NS. Approximately 18 subjects will be enrolled at approximately 7 sites. Subjects will be randomized (1:1:1) to treatment as follows:

1. QRX003 (dipalmitoyl hydroxyproline) lotion, 2% (Low dose)
2. QRX003 (dipalmitoyl hydroxyproline) lotion, 4% (High dose)
3. Vehicle lotion

Subjects will apply the assigned test article once daily in the morning to a designated Treatment Area for 12 weeks. Subjects will attend 5 clinic visits for up to 20 weeks.

This study aims to evaluate the efficacy and safety of lebrikizumab when used in combination with topical corticosteroid (TCS) treatment, compared with placebo, in pediatric participants with moderate-to-severe atopic dermatitis. Participants found to be eligible according to all of the study entry criteria will be randomly assigned in a 2:1 ratio to receive either lebrikizumab or placebo. This study can last up to 32 weeks, with 4 study periods. Screening Period: up to 4 weeks (≤30 days), TCS Standardization Period: 2 weeks, Treatment Period: 16 weeks, Post-Treatment Safety Follow-up Period: 12 weeks.
