Active clinical trials for "Pulmonary Arterial Hypertension"

As sitaxsentan is the agent most highly selective for ETA (Endothelin Type A (receptor)), and does not significantly impact sildenafil pharmacokinetics the combination of most promise for pulmonary arterial hypertension (PAH) therapy is these two oral drugs administered in combination.

As monotherapy for pulmonary arterial hypertension (PAH) begins to fail additional therapies are introduced. Although co-administration of sitaxsentan and sildenafil is well tolerated the controlled safety/efficacy database of the combination is limited.

The purpose of this study is to determine whether aspirin and simvastatin are safe and effective for the treatment of pulmonary arterial hypertension (PAH).

This clinical trial will study the safety, tolerability, and pharmacodynamics of single doses of MK-8892 in participants with pulmonary arterial hypertension (PAH). The primary objective is to estimate the measured peak effect of the highest acutely tolerated (HAT) single oral dose of MK-8892 on pulmonary vascular resistance (PVR).

This is a multi-center, Phase 2 Long-Term, Open Label Extension (OLE) Study to assess the safety and tolerability of pemziviptadil (PB1046) at an optimally titrated dose. This is a Long-Term, Open label Extension (OLE) Study for subjects with (PAH), having participated in double-blind Study PB1046-PT-CL-0004. The study will include adult subjects previously diagnosed with symptomatic PAH, who are receiving background clinician-directed therapy for PAH. During this period, subjects will continue to be followed for safety and tolerability, as well as for periodic efficacy, quality of life data and immunogenicity. The study will continue per the schedule of events until such time when pemziviptadil (PB1046) is able to be self-administered, becomes commercially available to the subjects in a particular country or region, or the sponsor terminates the study due to lack of efficacy, safety or other reasons.

This is a multi-center, randomized, double-blind, controlled, Phase 2 study to assess the safety, tolerability, and efficacy of pemziviptadil (PB1046) at the optimally titrated dose after 16 weeks of treatment. Subjects will be randomized in a 2:1 ratio to one of two parallel dose groups: a) high-dose group where PB1046 will be up-titrated from a 0.2 mg/kg minimally effective starting dose to a target high dose level of at least 1.2 mg/kg or higher to a maximally tolerated dose (MTD), or b) a low-dose group that will start at 0.2 mg/kg and remain at this minimally effective dose (MED) level with sham up-titration. The total treatment period will be comprised of 2 phases: 1) an initial 10 week dose titration phase in which weekly doses of PB1046 will be titrated (or sham titrated) up to a target dose level of at least 1.2 mg/kg or higher to the MTD, and 2) a maintenance of treatment phase that begins when subjects reach week 11 and continues for 6 weeks during which no further up-titration should occur.

It is recognized that patients with various forms of heart and lung disease exhibit varying degrees of pulmonary hypertension, pulmonary vascular remodeling, and right ventricular dysfunction. The genetic, molecular, and cellular processes driving these phenomena are not well understood. Rapid advances in high throughput omic methodology, combined with powerful bioinformatics and network biology capability, have created the opportunity to conduct studies that broadly search for homologies and differences across the spectrum of disease states associated with pulmonary hypertension, and determinants of the spectrum of right ventricular compensation that accompanies these conditions

The aim of the study is to examine the validity of peripheral oxygen saturation measurement during the 6-minute walk test in patients with Systemic Sclerosis (SSc) and to examine the utility of two other functional tests as markers of pulmonary involvement in patients with SSc.

the purpose of this study is to determine the effect of age on the Pharmacokinetics (PK) profile of BIA 5-1058 at steady state after multiple oral doses

The main objective of this study is to evaluate the safety and tolerability of 12-week oral CXA-10 therapy in subjects with pulmonary arterial hypertension, with additional evaluation on the clinical efficacy of oral CXA-10 on changes in hemodynamics, exercise capacity, cardiovascular function and patient reported outcomes.
