Heritable pulmonary arterial hypertension

This study tests an experimental drug called IKT-001 in people with pulmonary arterial hypertension (PAH), a condition where high blood pressure in the lungs makes it hard to breathe and move. About 486 adults will receive either IKT-001 or a placebo to see if the drug improves b…

This pilot study tests whether a sleep health program designed for couples can improve sleep and blood pressure. Fifty couples will take part in an 8-week program that includes sleep education, coaching, and a Fitbit to track sleep. The goal is to see if working together as a tea…

This study follows 280 adults and children with pulmonary hypertension who are already taking macitentan or selexipag in a previous trial. The goal is to monitor long-term safety, including side effects and serious events, while allowing continued access to the medication. Partic…

This early-stage study tests a new way to use a heart-lung machine (ECMO) in 4 people waiting for a lung transplant who also have heart failure from high blood pressure in the lungs. The goal is to see if this approach can keep them alive and stable until they receive a transplan…

This study tests whether giving iron through a vein can help people with pulmonary hypertension (high blood pressure in the lungs) who also have low iron levels. Many patients with this condition have trouble absorbing iron from pills. The trial will compare intravenous iron to a…

This study tests a new device for people with pulmonary hypertension, a condition where high blood pressure strains the heart. The device is implanted to help the heart pump better. About 30 adults with severe symptoms will take part to see if the device is safe and works well.

This phase 2 trial is testing whether two existing drugs, empagliflozin (used for diabetes) and ranolazine (used for chest pain), can improve right heart function in 30 people with pulmonary hypertension and right heart failure. Participants will receive one of the drugs plus sta…

This early study tests whether a peptide called IRW, found in egg white hydrolysate, can help manage high blood sugar and blood pressure. About 28 participants at risk for or with type 2 diabetes will consume a smoothie with the peptide on four separate days, while a healthy cont…

This study explores whether a simple, radiation-free scan of the nailbeds—called nailfold capillaroscopy—can help diagnose and monitor pulmonary hypertension (PH), a condition of high blood pressure in the lungs. Researchers will compare nailbed blood vessel measurements with inv…

This study examines why fat accumulates in the right ventricle of people with pulmonary arterial hypertension (PAH) and how it affects heart function and exercise ability. Researchers will use MRI and blood tests in 75 adults with PAH to track changes over time. The goal is to be…

This study looks at whether giving mothers in Brazil an extra $40 per month (compared to just $2) can protect their children's brain development and mental health. About 450 children aged 7-10 from low-income families will be followed for 2 years. Researchers will measure stress,…

This study is looking at people with pulmonary arterial hypertension (PAH), those with a genetic risk but no disease, and healthy individuals. Researchers aim to find molecular and physical markers that explain why some people get PAH and others stay healthy. The goal is to impro…

This study aims to develop a noninvasive way to detect blood vessel changes in the lungs of people with Group 3 pulmonary hypertension (PH) using a special MRI technique. Researchers will compare MRI results with lung tissue from 30 patients awaiting lung transplant. The goal is …

This study involves 100 people with suspected pulmonary hypertension who are already scheduled for a right heart catheterization. During the procedure, doctors will take two extra blood samples from a specific position in the lung artery to analyze oxygen and other gas levels. Th…

This study will follow at least 700 people with pulmonary hypertension to track side effects and deaths related to targeted medications. Participants will be checked every 6 months using a computer system. The goal is to better understand the safety of these drugs in real-world u…

This study looks at how hormones and metabolism are involved in pulmonary arterial hypertension (PAH), a serious lung condition. Researchers will measure sex hormone levels, insulin resistance, and test two potential treatments—metformin and ACE-2—in small groups. The goal is to …

This study looks at whether the way blood cells work and handle stress can help doctors detect and predict the course of pre-capillary pulmonary hypertension, a serious lung condition. Researchers will collect blood samples from 120 patients during routine visits over three years…
