Recruiting studies
- NCT05140525RecruitingPhase 3
BPA plus CTEPH medicines to improve heart strain
This trial tests whether starting specific medicines for CTEPH and then doing balloon pulmonary angioplasty (BPA) can improve how well the right side of the heart is working. It may help people who cannot have surgery (PTE) and are newly starting CTEPH/PAH-targeted treatment.
Durham, North CarolinaAges 18 years+ - NCT07299227Recruiting
Study on heart and lung effects of BPA in CTEPH
This study uses special heart scans (CMR with 4D flow) to see how a procedure called BPA affects blood flow in the heart and lungs for people with a rare type of high blood pressure in the lungs (CTEPH). It may help doctors understand how well BPA works beyond just symptoms.
Bad Nauheim, HesseAges 18–99 - NCT06865326Recruiting
Early detection of CTEPH after pulmonary embolism
This trial is for people who had a pulmonary embolism (a blood clot in the lungs) in the last 3 to 12 months and are still on blood thinners. It aims to find early signs of a serious condition called CTEPH (chronic blood clots in the lungs) so treatment can start sooner.
BrnoAges 18 years+ - NCT06105242Recruiting
Sex differences in CTEPH heart function and recovery
This study looks at how CTEPH (a type of high blood pressure in the lungs caused by blood clots) affects heart function differently in men and women. It uses heart ultrasounds and pressure measurements to see if recovery after surgery differs by sex.
Murray, UtahAges 18 years+ - NCT07777445Recruiting
Oxygen treatment during exercise for lung and pulmonary vascular disease
This study compares breathing normal air versus low-flow liquid oxygen during exercise to see if oxygen helps improve performance in people with conditions affecting the lungs or the blood vessels in the lungs. You would exercise while using a portable oxygen device and then without it to compare the effects.
Zurich, Canton of ZurichAges 18 years+ - NCT07777367Recruiting
Exercise with liquid oxygen in chronic lung disease
This study compares how well people with chronic lung diseases perform during exercise when breathing regular air versus when using low-flow liquid oxygen. It aims to see if using liquid oxygen during exercise can improve exercise ability and quality of life.
Zurich, Canton of ZurichAges 18 years+ - NCT06715280RecruitingPhase 4
Switching from sildenafil to riociguat for CTEPH
This trial tests switching from sildenafil to a newer medicine called riociguat for people with CTEPH (a type of lung blood pressure problem) who still have symptoms after a balloon procedure. The goal is to see if the switch helps them feel better.
Hong KongAges 18 years+ - NCT05110066Recruiting
Compare two procedures for chronic lung blood-clot pressure
This study compares balloon pulmonary angioplasty versus pulmonary endarterectomy for people with chronic thromboembolic pulmonary hypertension (high blood pressure in the lungs due to long-lasting blood clots). It may help find which procedure works better for improving symptoms and lung circulation after treatment.
AarhusAges 18–79 - NCT05311072Recruiting
Update a CTEPH patient database in China
This study helps doctors update and improve how they understand chronic thromboembolic pulmonary hypertension (CTEPH) in patients in China. It likely involves sharing your medical information (not a new drug) and confirming your diagnosis details to support future research.
BeijingAges 14 years+ - NCT06922240RecruitingPhase 3
Stopping riociguat to see how the heart responds in CTEPH
This trial is for people with a type of long-term blood clot in the lungs (CTEPH) who have been taking riociguat for at least 12 weeks. It will see what happens when the medication is stopped, focusing on how the right side of the heart is doing.
Beijing, ChinaAges 18 years+ - NCT05719415Recruiting
Testing balloon treatment effects on lung blood-vessel surface area
This study looks at how a procedure called balloon pulmonary angioplasty changes measurements in lung blood vessels in people with chronic thromboembolic pulmonary hypertension. It may help doctors understand what changes the treatment makes and why.
Montreal, QuebecAges 18–75 - NCT07522203Recruiting
Heart Function Recovery After Balloon Angioplasty for Lung Blood Clots
This study looks at how a minimally invasive procedure called balloon pulmonary angioplasty (BPA) helps patients with chronic blood clots in the lungs improve their heart function and overall recovery. Researchers will measure blood flow patterns in your arteries before and after the procedure to understand how well your heart recovers.

Common questions
- Are there clinical trials for cteph?
- Yes. Clin2 currently lists 12 recruiting cteph 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 cteph 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 cteph 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.
