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.

The purpose of this study is to find out how long ustekinumab stays in and acts in participant's who are diagnosed with pediatric psoriasis and juvenile psoriatic arthritis. This is measured by blood tests. Another purpose is to find out if ustekinumab can cause side effects, which are unexpected or unwanted reactions from taking a drug. About 75 children will take part in this study worldwide. Participants will be in the study for a maximum of about 16 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 study is to test whether a drug called PRA023/MK7240 (the study drug) is a good treatment for patients with Systemic Sclerosis associated with Interstitial Lung Disease (SSc-ILD). The study drug PRA023/7240 is an investigational drug that is given by infusion every 4 weeks. An investigational drug is not approved by The US Food and Drug Administration. It can only be used in a research study like this one. In this study, PRA023/MK7240 will be compared with a placebo (dummy drug). The placebo will be a saline solution that does not have any study drug in it. The comparison with the placebo helps to determine whether the effects seen in your body is because of the PRA023/MK7240 or not. This is a randomized study meaning that you will be assigned by chance (like flipping a coin) to receive either the study drug or placebo. This will be done with the help of a computer-based program and you will have 50% chance of receiving either the study drug or placebo. The study is double-blinded study and 50 weeks long, meaning you and your study doctor will not know what you are receiving, the study drug or placebo.

The study is sponsored by Prometheus Biosciences, Inc., a subsidiary of Merck & Co., Inc. The study is being done at approximately 25 sites across the United States. The main portion of the study will require 15 visits to the MUSC main campus and will have the following procedures completed over the course of your participation: blood draw, physician-led assessments of your disease (for example physical exam and skin thickness testing), tests to assess your pulmonary function and health (Pulmonary Function Test (PFT) and High Resolution Computed Tomography (HRCT)), electrocardiogram, as well as asked to complete surveys. If you complete the initial blinded treatment period of 50 weeks, the study doctor will discuss whether you are eligible to enter the open label period of the study, meaning no placebo. If you are eligible and agree, you will receive 500 mg of study drug once every 4 weeks for an additional 52 weeks. Compensation is available for participation.

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.

The purpose of this study is to test whether a drug called HZN-825 (the study drug) is an appropriate treatment for patients with Systemic Sclerosis (SSc). HZN-825 is an investigational drug that taken by mouth as a pill. An investigational drug is not approved by The US Food and Drug Administration and can only be used in a research study, like this one.

In this study, HZN-825 will be compared with a placebo (a pill that looks like the study pill but does not have any study drug in it). The comparison with the placebo helps to determine whether the effects seen in your body is because of HZN-825 or not. This is a randomized study meaning that you will be assigned by chance (like flipping a coin) to receive either the study drug or placebo. This will be done with the help of a computer-based program, and you will have 67% chance of receiving HZN-825. The study is double-blinded, meaning you and your study doctor will not know what you are receiving, the study drug or placebo. Should an emergency arise, and it is determined necessary, your study doctor will be able to find out what medication group you have been assigned.
