This is a prospective cohort study of subjects with portal hypertension to examine whether increased sphingosine 1 phosphate : ceramide ratio and circulating bile acids are associated with HPS in patients with advanced liver disease. The study will consist of 400 individuals who are evaluated for liver transplantation at the Field Centers. This population has advanced liver disease and will represent the population with cirrhosis at the Centers. As is considered standard of clinical care for these patients and required for liver transplant evaluation, patients will undergo phlebotomy, interviews, pulmonary function testing, echocardiography, and arterial blood gas sampling at their initial evaluation. During the clinical phlebotomy, additional samples will be drawn for research purposes. If any of these procedures does not occur during the clinical visit, it may be conducted for research purposes. Six minute walk testing, frailty scales, SF36, and optional actigraphy, all of which are research-only assessments, will be performed at baseline. Subjects will then be followed via phone for the duration of the study period.

This open-label, LTFU study will evaluate the safety, tolerability, and efficacy of sotatercept in participants with PAH previously treated with sotatercept or placebo. Participants eligible to enroll in this study will have participated in and completed the relevant study participants of the parent PAH sotatercept clinical trials. The estimated duration of the A011-12 study is up to 7 years; however, the estimated duration of enrollment for each participants is approximately 4 years. There is no formal sample size calculation for the study. The number of participants in this LTFU study is dependent upon the enrollment in the parent protocols. Approximately 700 participants are anticipated to enroll in the study.

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.

The study is sponsored by Horizon Therapeutics Ireland DAC. The study is being done at approximately 135 sites across the world. The study is 60 weeks long will require 12 visits to the MUSC main campus. During study participation, the following procedures will be completed: 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 being asked to complete surveys about your overall health and wellbeing. Compensation is available for participation

This is a Phase 3, randomized, double-blind, placebo-controlled, efficacy and safety study of subjects with IPF treated with inhaled treprostinil over a 52-week period. This study is investigating whether a drug called inhaled treprostinil (brand name Tyvaso®) works to help people with IPF improve their lung function tests. The purpose of this research study is to see how well inhaled treprostinil works in participants with IPF and to gather information on how safe it is. This study will look at changes in your breathing tests, also called lung function tests. About 396 people will participate in this study from about 100 medical centers. Your participation in this study is voluntary and will last approximately 58 weeks. This time includes a Screening Period that could last up to approximately 6 weeks plus a 52-week Treatment Period.

The objective of this study is to evaluate the effects of sotatercept treatment (plus background PAH therapy) verses placebo (plus background PAH therapy) on time to clinical worsening (TTCW) in participants who are newly diagnosed with PAH and are in intermediate or high risk of disease progression. The study is divided into a Screening Period (up to 4 weeks), followed by a Double-blind Placebo-controlled (DBPC) Treatment Period. When a participant experiences an event of clinical worsening, they will complete the End of Treatment (EOT) Visit and will be eligible to enroll immediately in the open-label, long-term follow-up (LTFU) study, A011-12 (SOTERIA). Up to 662 participants will be randomly assigned in a 1:1 ratio to the 2 study treatment groups (331 participants per arm).

This study is designed to evaluate a new therapy formulation for Alpha-1 Antitrypsin Deficiency (AATD). AATD is an inherited condition in which a person has low blood levels of a protein known as alpha-1 protease inhibitor (called Alpha1-PI). AATD causes an increased risk of chronic obstructive pulmonary disease (COPD) in the form of emphysema (long term lung disease) and, less frequently, other diseases.

This study is being conducted to evaluate the safety and tolerability of 2 different doses of Alpha-1 drugs (Alpha-1 15% and Liquid Alpha1-PI) in participants with AATD. Participants will be placed into one of two groups. Each group will receive both drugs at different points in the treatment period and because this is an "open label", study participants and the study staff know which dose of study drug participants receive. The study will last up to 486 days (16 months). Many visits are able to be conducted through home health care, lessening the need to come into the clinic.

Alpha-1 15% is an investigational product, meaning it is not approved by the U.S. Food and Drug Administration (FDA). The other drug in this study is Liquid Alpha1-PI (licensed as Prolastin®-C Liquid) and is an FDA approved treatment for adults with emphysema due to AATD. However, it is only approved for the recommended dose of 60 mg/kg. This study includes both the FDA approved 60mg/kg of Liquid Alpha1-PI and an experimental dose of 120 mg/kg that is not FDA approved. Alpha-1 15% is given as an injection under the skin and Liquid Alpha1-PI is given as an infusion into the veins.

You may or may not directly benefit from participation. However, you may help advance scientific knowledge in the treatment of AATD. Currently, the only FDA approved treatment for AATD is IV infusions of Liquid Alpha1-PI. Since the drug being studied, Alpha-1 15%, is injected with a small needle under your skin, there may be a benefit to future patients by providing flexibility of treatment route options as well as stability in serum alpha1-antitrypsin levels.

A main focus of the study is to identify characteristics that can be changed such as smoking, vaping and diet, environmental exposures (e.g. pollution such as car exhaust, allergies such as pet dander) that affect lung function and risk of future lung disease. We also are looking for biomarkers (e.g. measurements of specific substances in nose, blood, and urine samples) and genetic markers that can provide us with information about lung health. The findings in this study are considered research and are not the same as "genetic testing."

The objective of this study is to evaluate the effects of sotatercept treatment (plus maximum tolerated background PAH therapy) versus placebo (plus maximum tolerated background PAH therapy) on time to first event of all cause death, lung transplantation, or PAH worsening-related hospitalization of ≥ 24 hours, in participants with WHO FC III or FC IV PAH at high risk of mortality. The study targets patients with symptomatic PAH (WHO FC III or FC IV at high risk of mortality) who present with idiopathic or heritable PAH, PAH associated with connective tissue diseases (CTD), drug- or toxininduced, post-shunt correction PAH, or PAH presenting at least 1 year following the correction of congenital heart defect. Up to 166 participants will be randomly assigned in a 1:1 ratio to the
2 study treatment groups (83 participants per arm). Maximum study duration for a given participant in this study will be up to approximately 49 months.

The purpose of this study is to learn more about the safety and effectiveness of the drug omadacyline for people with Nontuberculous Mycobacterial (NTM) pulmonary disease, caused by a type of mycobacteria called Mycobacterium abscessus complex (MABc). Participants will be randomly assigned to receive either omadacycline or placebo, with a 60% chance of being treated with omadacycline and a 40% chance of being treated with placebo. About 75 men and women with NTM lung infection caused by MABc, ages 18 and up, will be in this study, with an estimated 4 participants being enrolled from the MUSC site. Participants will be in this study for approximately 5 months in total, beginning with the Screening visit and continuing until their last study visit.

The purpose of this research study is to continue to test how well the Endospan NEXUSTM Aortic Arch Stent Graft System performs in the treatment of a diseased aortic arch. The aortic arch is the top part of the main large vessel that carries blood away from the heart. A stent graft is a self-expanding frame that is covered with a material intended to seal the vessel walls.
The NEXUS Aortic Arch Stent Graft System is delivered to the diseased area of your aorta by traveling through your vascular system using fluoroscopic guidance (x-ray pictures), starting with a small incision or needle puncture near your groin (inner thigh). The NEXUS Aortic Arch Stent Graft System is being studied and is not approved by the FDA which means it is investigational in this study. The NEXUS Aortic Arch Stent Graft System has CE Mark which means it is approved for use in Europe. The NEXUS Aortic Arch Stent Graft System is only available through the clinical study in the United States.
