365 Clinical Trials for Various Conditions
The overall study objectives outlined in this study are to derive 129Xe MRI pulmonary vascular biomarker signatures that differentiate common subtypes of PAH and to determine the ability of 129Xe MRI to longitudinally monitor disease progression and response to therapy in PAH, with the aid of additional assessments, such as labs, echocardiography, and six-minute walk distance (6MWD).
Pulmonary arterial hypertension (PAH) is a severe disease with a delayed diagnosis and markedly elevated mortality. High-risk populations, such as those with known genetic defects, provide a unique opportunity to determine the features of susceptibility and resilience to PAH. This proposal will fundamentally overturn the prevailing understanding of PAH by creating molecularly-driven signatures of susceptibility and resilience, provide novel insight into disease severity, and potentially identify new therapeutic targets.

The investigators propose to study the relationship between right ventricle (RV) steatosis and RV function, exercise capacity, and outcomes in humans with pulmonary arterial hypertension (PAH) and to identify potential drivers of lipid accumulation.
This study plans to learn more about activity levels in children with pulmonary hypertension. Pulmonary hypertension is a condition where the pressure in the lungs is higher than normal. This can affect the person's heart. The purpose of this study is to see if measuring activity in children with pulmonary hypertension and comparing it to activity in children without pulmonary hypertension can give their doctor helpful information on how they are feeling and how their treatment is working.
This study proposes the use of a mobile health intervention (utilizing a smart phone app) to encourage increased exercise in PAH patients. The study will be a randomized trial to examine feasibility of an mHealth (mobile device) Fitbit Charge HR and cell phone application intervention to improve step counts and increase participants activity level as compared to no intervention. The Fitbit Charge Heart Rate (HR) monitors activity and the cell phone application provides encouragement notifications to half the subjects while the other half do not receive encouragements.
The purpose of this study is to determine if dynamic hyperinflation seen in patients with idiopathic pulmonary artery hypertension (iPAH) improves with albuterol therapy.
The purpose of this study is to determine if cardizem is effective in the treatment of nitric oxide non-responder pulmonary arterial hypertension.
Our hypothesis is that IV or SQ Treprostinil can improve 6 minute walk distance, hemodynamics and quality of life in patients with interstitial lung disease and severe secondary pulmonary arterial hypertension.
Pulmonary Arterial Hypertension (PAH) in the setting of Idiopathic Pulmonary Fibrosis(IPF)is a risk factor for morbidity and mortality in the peri-lung transplant(LT) setting. Currently there is no significant data to support the use of pulmonary vasodilators for PAH in the setting of interstitial lung disease such as IPF. The majority of IPF patients have PAH either at rest or during exercise. The study hypothesis is that bosentan may improve morbidity and mortality in the peri-LT setting in both IPF cohorts with either resting or exercise PAH.
The purpose of this study is to determine the safety and maximum tolerated dose of inhaled NX1011 for the treatment of pulmonary arterial hypertension (PAH).
Rationale: Idiopathic pulmonary arterial hypertension (IPAH) is characterized by in situ thrombosis and increased thromboxane A2 (Tx-M) synthesis. While both may be attributable to abnormal platelet function, there are no studies of anti-platelet therapy in IPAH. Objectives: The purpose of this study is to assess the effects of aspirin (ASA) and clopidogrel on platelet function and eicosanoid metabolism in patients with IPAH.
Randomized, triple-masked, parallel arm clinical trial of empagliflozin versus placebo in pulmonary arterial hypertension (PAH) participants on stable approved PAH-targeted medical therapy.
This is a 20-week, Phase 1, single-center, open-label, dose-escalation study evaluating the safety and tolerability of daily oral artesunate in patients with PAH.
Patients with Group 1 pulmonary hypertension will be enrolled in this study. Investigators will test the hypothesis of low-level tragal stimulation in patients with pulmonary hypertension. The study will be conducted over 4 weeks and patients will undergo low-level tragus stimulation for 1 hour every day for 4 weeks. At baseline the following tests will be conducted-6-minute walk distance, vascular function testing using noninvasive device and blood samples will be collected. Patient will also undergo a limited echocardiography to assess right ventricular function. After 4 weeks of stimulation patients will come back to undergo these tests again. Investigators hypothesized that low-level tragus stimulation (neuromodulation) will lead to improvement in vascular function, 6-minute walk distance and blood based biomarkers in patients with pulmonary hypertension.
Researchers are looking for other ways to treat people with PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow to the lungs. The goal of the study is to learn: * What happens to different doses of sotatercept in a person's body over time when it is given using weight-banded doses compared to weight-based doses. There may be differences in how the medicine works with the new dosing method (weight-banded dosing) being studied in this trial. * About the safety of sotatercept and if people tolerate it
The purpose of the study is to learn more about how low-resistance training impacts frailty and the quality of life of people with pulmonary arterial hypertension (PAH). Low-resistance training is an evidence-based approach that may help patients improve their functional ability.
This pilot clinical trial will evaluate the initial safety, feasibility, and pharmacokinetics of microbiota transplant therapy (MTT) with antibiotic pre-conditioning and fiber supplementation vs. placebo in patients with pulmonary arterial hypertension (PAH). This trial will inform development of future trials of MTT as a treatment for PAH. 24 PAH patients will be randomized to receive either MTT with antibiotic preconditioning + fiber supplementation, MTT with antibiotic preconditioning + placebo supplementation, or placebo + placebo supplementation. MTT will in a capsule form composed of freeze-dried, encapsulated intestinal microbiota from healthy donors. Fiber supplementation will be 10-14 gm oral fiber supplement. Patients will be followed at week 1, week 2, week 4, week 12, and week 24. Patient will undergo stool sample collection at baseline, week 1, week 4, and week 12, blood sample collection at baseline, week 4, and week,12. In addition, patient will undergo an echocardiogram, six-minute walk test (6MWT) and quality of life questionnaire at baseline and at week 12.
The purpose of this study is to evaluate whether a home rehabilitation program for patients diagnosed with Pulmonary Arterial Hypertension (PAH) will decrease Cardiac Effort (number of heart beats used during 6-minute walk test/walk distance) and improve quality of life. Ultimately, this information could help improve the management of patients with PAH.
The purpose of this study is to see if the drug sotatercept given for 36 weeks improves the functioning of the heart and improves quality of life.
The purpose of the study is to learn how the study medicine called PF-07868489 is tolerated and acts in healthy adult people and people with pulmonary arterial hypertension (PAH). Part A: An investigator- and participant-blind, sponsor-open, placebo-controlled, single ascending dose study to assess the safety, tolerability, and pharmacokinetics (PK) of PF-07868489 in healthy adult participants. Part B: A 24-week, randomized, double blind, placebo-controlled study to assess the safety, tolerability, PK, and pharmacodynamics (PD) of PF-07868489 in adult participants with PAH.
Study KER-012-A201 is Phase 2, double-blind, randomized, placebo-controlled study to determine the efficacy and safety of KER-012 compared to Placebo in adults with PAH (WHO Group 1 PH) on stable background PAH therapy. The study is divided into the Screening Period, Treatment Period, Extension Period, and Follow-Up Period.
The purpose of this study is to measure the long-term safety and efficacy profile of LTP001 in participants with pulmonary arterial hypertension (PAH). The study offers participants who had completed the CLTP001A12201 double-blind parent study in PAH an opportunity to receive LTP001 (whether they were on LTP001 or not). Unblinding of the treatment received in CLTP001A12201 is generally not needed, but can occur on request by the investigator.
The primary purpose of the study is to evaluate the safety and tolerability of the long-term use of TPIP in participants with PAH from studies INS1009-201 (NCT04791514), INS1009-202 (NCT05147805) and other lead-in studies of TPIP in participants with PAH.
The primary objectives of the study are to evaluate the safety and tolerability, and pharmacokinetics (PK) of sotatercept over 24 weeks of treatment in children ≥1 to \<18 years of age with PAH World Health Organization (WHO) Group 1 on standard of care (SoC). There is no formal hypothesis.
IMPAHCT-FUL: Inhaled Imatinib Pulmonary Arterial Hypertension Clinical Trial - Follow Up Long Term Extension (LTE) Trial was a follow up study to establish the long-term safety of AV-101. Subjects who successfully completed the 24-week placebo-controlled parent trial (AV-101-002, NCT#05036135) were offered the opportunity to continue into this LTE study. Subjects who enrolled in the study were to receive one of three active AV-101 doses until such time as the optimal dose was selected in the parent study.
The purpose of this study is to test new technology and health coaching aimed to help people with PAH become more physically active in their daily lives.
Patients with pulmonary arterial hypertension (PAH) have reduced health related quality of life (HRQOL) and impaired exercise capacity. Despite fourteen approved therapies, most patients die within ten years. Increasing physical activity is highly efficacious in PAH, resulting in six-minute walk distance (6MWD) and HRQOL improvement that often exceeds the effect of medications. Prior activity studies required inpatient rehabilitation, which is impractical, hard to sustain, and poorly scalable to a rare disease. The Investigators propose a randomized trial of smart texts versus usual care for 6 months. The Investigators will randomize 100 PAH patients to the mHealth intervention or usual care. The Investigators will test the effect of a text-based mHealth intervention on HRQOL in PAH using the PAH-specific emPHasis-10 questionnaire. The Investigators will also test the effect of an mHealth intervention on exercise capacity, measured by a supervised home-based 6MWD test. Finally, the Investigators will examine the effect of the intervention on time to clinical worsening (composite of PAH therapy escalation, PAH hospitalization, and death) one year after randomization.
Pulmonary arterial hypertension (PAH) is a disease where the blood pressure in the pulmonary arteries (PAP) is high. PAH increases the risk of adverse events, including death, during and or after procedures. The severity of baseline PAH correlates with the incidence of major complications, such that those with PAP higher than their systemic blood pressure (SBP) had a 8 fold increased risk of complications. These children present for procedures where an acute exacerbation of their chronic illness-termed Pulmonary Hypertensive (PH)crisis, can occur, often resulting in death if not detected and managed expeditiously. Unfortunately there is little data and no consensus in the pediatric literature on how PH crisis should be managed. --------------------------------------------------------------------------------
In this study, hyperpolarized 129Xe MRI will be used to evaluate treatment efficacy in patients with pulmonary arterial hypertension (PAH). Participants will be imaged at 4 timepoints (baseline, 6 weeks post-therapy initiation, 12 weeks, and 18 weeks). Images will be analyzed to develop new biomarkers and to understand treatment effects.
The primary objective of this study is to assess the effect of early and rapid treprostinil therapy for mean pulmonary artery pressure (mPAP) reduction to improve right ventricular (RV) function and reverse RV remodeling in participants with pulmonary arterial hypertension (PAH).
