São Paulo, São PauloAges 18 years+ - NCT06968962Recruiting
Starting PAH treatment: one drug first or two drugs together?
This study compares starting with one medication versus two medications together for people with pulmonary arterial hypertension (PAH). It aims to find out which approach works better for low- or intermediate-risk patients.
Hangzhou, ZhejiangAges 18–80 - NCT06850792Recruiting
Improving treatment adherence with telemedicine and guidance
This study tests whether regular remote check-ins and guidance can help people with pulmonary arterial hypertension stick to their treatment plan. You would be followed by phone or video from University of Sao Paulo.
São Paulo, São PauloAges 18 years+ - NCT03683186Enrolling by invitationPhase 3
Long-term study of ralinepag for pulmonary hypertension
This study follows people with pulmonary arterial hypertension (PAH) to see how safe and effective ralinepag is over the long term. It may help your care team understand what to expect from continued treatment and monitoring.
Phoenix, ArizonaAges 18 years+ - NCT01884051Recruiting
Study of blood and skin changes in pulmonary hypertension
This study looks at how hormones, metabolism, and body signals relate to pulmonary arterial hypertension. You may be eligible if you (or a family member) have idiopathic, inherited, or related pulmonary arterial hypertension, and you can do required blood and other testing.
Nashville, TennesseeAges Up to 90 years - NCT06317805RecruitingPhase 4
Three-medicine start vs. two oral pills for new PAH
This study compares starting treatment with three medicines, including a continuous infusion (treprostinil), versus two oral medicines for people newly diagnosed with moderate-to-high risk pulmonary arterial hypertension (PAH). The goal is to see which approach improves heart function and symptoms more effectively.
LinzAges 18–70 - NCT07824674RecruitingPhase 2/Phase 3
On-demand sildenafil for exercise capacity in pulmonary arterial hypertension
This trial tests whether taking sildenafil (a medicine that helps relax blood vessels) on demand, compared to a sugar candy placebo, can improve exercise capacity in people with pulmonary arterial hypertension (PAH). Participating may help you exercise more easily and contribute to better treatment options.

- Yes. Clin2 currently lists 55 recruiting pah studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a pah trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a pah trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
