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.

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.

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.

This is a Phase 3 multicenter, single-arm, open-label extension (OLE) study designed to investigate the long-term safety, tolerability, and efficacy of risankizumab 150 mg or 55 mg by weight every 12 weeks (Q12W) in the treatment of moderate to severe plaque Ps in eligible subjects who have completed all assessments in Study M19-977 and elect to participate in Study M19-973. The study is comprised of a 216-week treatment period and a follow-up phone call for safety approximately 140 days (20 weeks) after the last dose of study drug.

This study aims to evaluate the safety and efficacy of isotretinoin ointment (TMB-001 0.05%) in treating subjects > or = to 6 years of age with lamellar ichthyosis, and aims to assess the bodily absorption of the cream across application frequencies. Subjects with ARCI/RXLI will be randomized 2:1, to either receive the TMB-001 0.05% isotretinoin ointment or a vehicle ointment - applied daily - for 3 weeks. Subsequently, dosing will be increased to twice daily for 9 weeks. If significant improvement is observed at the end of the 9 weeks, subjects will be randomized 1:1 to receive the TMB-001 0.05% ointment, either applied daily or twice-daily, for 12 weeks. Prior to the Phase III trial, subjects will have the option to participate in a 14 day treatment period with TMB-001 0.05% - twice daily - followed by continued treatment with TMB-001 0.05% twice daily for 10 weeks.

In current Dermatology practice, options for vitiligo remain limited. The purpose of this study is to determine if once daily dosed topical rapamycin is effective for the treatment of patients with vitiligo. Participants will apply either 0.1% topical rapamcyin or 0.001% topical rapamycin for six months to a lesion on one side of the body, and topical placebo to a corresponding lesion on the opposite side of the body. The study also aims to evaluate patient satisfaction and identify any adverse effects on these dosing regimens.

The purpose of this research study is to develop a better understanding of the cause and natural history of vascular anomalies and related syndromes. This study is being done in order to develop a better understanding of the cause of vascular anomalies in order to to improve care for people who are affected by these anomalies and related syndromes.

This study is being done at the University of Wisconsin-Madison (UW-Madison) and other sites in North America and Europe. A total of about 1000 people will participate in this study. About 20 – 30 people will take part in the study here at the Medical University of South Carolina.
