The Pulmonary Hypertension Association (PHA) provides this tool to help participants learn more about research ongoing in PH. Use the filters below to narrow the search results to fit your personal needs. Each listing describes current research, who qualifies to participate, and whom to contact for information.
No personal information can be collected through this tool. The information presented on the PHA Clinical Trials page has been obtained directly from ClinicalTrials.gov, a service of the U.S. National Institutes of Health (NIH). PHA recommends that you use the information in this resource to begin a conversation with your PH specialist about whether or not participating in research is right for you.

4D-flow Cardiac MRI to Assess Pulmonary Arterial Pressure in Pulmonary Hypertension
Due to radiation exposure and low but real risk of morbidity and mortality associated with right heart catheterization, non-invasive procedures to estimate mPAP are desired for the diagnosis of PH or to monitor treatment effectiveness. Echocardiography is used as a screening tool to estimate systolic pulmonary arterial pressure (sPAP), but due various limitations, this technique is not considered to be sufficiently accurate for the diagnosis of PH. The aim of 4D flow MRI is to evaluate the complete time-varying tridirectional velocity field in a volume of interest. It enables flow and velocity measurements in a vascular region of...
Activity Monitoring in Pulmonary Hypertension
This is a prospective, longitudinal, observational study of free-living activity trackers and patient reported outcomes to test the hypothesis that daily activity will have stronger prognostic value than 6MWD in patients with pulmonary hypertension after 12 weeks.
Acute Assessment of the Aria CV System in Patients With WHO Groups 2 and 3 Pulmonary Hypertension
This study is a prospective, non-randomized, two arm, single-center acute feasibility study assessing safety and performance of the Aria CV Acute PH System in WHO Group 2 and 3 PH patients.
Adherence of Diuretics in Pulmonary Hypertension
In this prospective study, the investigators will implement a systematic assessment of adherence to diuretics in a cohort of patients with precapillary pulmonary hypertension. This study is designed to: - determine the overall adherence rates for diuretic regimen - determine the determinants of non-adherence to diuretics - assess the risk of PH worsening occurrence in the non-adhesion group
Algorithms to Diagnose Pulmonary Arterial Hypertension
The investigators intend to evalute the value of radiomics signature of pulmonary vessels from chest computed tomography (CT) for dianosis and prognosis of pulmonary arterial hypertension.
A Long-term Extension Study of Riociguat in Patients With Symptomatic Pulmonary Arterial Hypertension.
To provide riociguat therapy to eligible patients with PAH originating from Bayer-sponsored trials with BAY63-2521/ Riociguat / Adempas® who are currently or recently treated in these trials until lack of patient benefit as assessed by investigator, or commercial availability and reimbursement.
A Long-term Follow-up Study of Sotatercept for PAH Treatment (MK-7962-004)
This study is being conducted to assess the long-term safety, tolerability, and efficacy of sotatercept in participants with Pulmonary Arterial Hypertension (PAH). This open-label, long-term follow-up (LTFU) study is supported by data from the PULSAR study (Phase 2, NCT03496207) in which treatment with sotatercept resulted in hemodynamic and functional improvements in the study participants, including those receiving maximal PAH therapy with double/triple drug combinations and intravenous prostacyclin. The primary objective of this open-label, LTFU study is to evaluate the long-term safety and tolerability of sotatercept when added...
A Mechanistic Study of Inhaled Nitric Oxide in COPD
There is a lack of effective treatments for chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension. Previous studies have found that inhaled nitric oxide (iNO) can reduce pulmonary artery pressure and improve exercise capacity in COPD with pulmonary hypertension patients. However, the specific mechanism is unclear. The study aims to evaluate pulmonary ventilation/perfusion, pulmonary artery pressure, oxygenation, symptoms and quality of life in COPD with pulmonary hypertension patients after short-term treatment with iNO. Observing a series of pathophysiological changes caused by the treatment of ...
An Extension Study to Assess the Safety, Tolerability, and Effectiveness of the Long-Term Use of Treprostinil Palmitil Inhalation Powder (TPIP) in Participants With Pulmonary Hypertension Associated With Interstitial Lung Disease (PH-ILD)
The primary objective of this study is to evaluate the safety and tolerability of the long-term use of TPIP in participants with PH-ILD from Study INS1009-211 (NCT05176951) and other lead-in studies of TPIP in participants with PH-ILD.
Antiphospholipid Syndrome and Postpartum Pulmonary Artery Pressure
The primary goal of this observational study is to learn about postpartum pulmonary artery pressure in women who suffered from Preeclampsia and Antiphospholipid Syndrome. The main question it aims to answer is whether the conjunction of preeclampsia with obstetric antiphospholipid syndrome significantly foster the development of long-lasting pulmonary hypertension. Only participants who suffered from preeclampsia during pregnancy will be followed for a period up to 3 years postpartum. Researchers will compare women with or without obstetric antiphospholipid syndrome.
