Active clinical trials for "Familial Primary Pulmonary Hypertension"

This is an open-label, nonrandomized extension to study AC-066A301. The study will assess safety and tolerability of ACT-385781A while providing a means for continuing treatment after ending participation in study AC-066A301.

This is a prospective, multi-center, open-label, randomized, Phase IV exploratory study comparing safety, tolerability, pharmacokinetics, and effectiveness of ACT-385781A and Flolan (epoprostenol sodium) in patients with pulmonary arterial hypertension who are naïve to injectable prostanoid treatment and in need of such treatment. Approximately 30 patients from 8 U.S. clinical sites will be randomized to receive either ACT-385781A or Flolan (2:1 respectively) for 28 days of treatment.

This is an open-label, non-randomized extension to study AC-066A401. The study will assess safety and tolerability of ACT-385781A and Flolan (epoprostenol sodium) while providing a means for continuing treatment after ending participation in study AC-0066A401.

The objectives of the FUTURE 3 Study Extension are to evaluate the long-term safety, tolerability and efficacy of the pediatric formulation of bosentan two versus three times a day in children with Pulmonary Arterial Hypertension (PAH).

This is a 12-week, international, multicenter, double-blind, three-group, dose-response study to assess the safety and efficacy of BPS-MR in patients with PAH. Eligible patients will have been previously diagnosed with PAH and will be on a stable course of an ERA and/or PDE-5 inhibitor for at least 60 days prior to Baseline. Patients will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio and will be stratified by PAH background therapy (Endothelium Receptor Antagonist (ERA), Phosphodiesterase-5 (PDE-5), and both). The treatment groups consist of one Maximum Tolerated Dose (MTD) and two Fixed Dose (FD) groups. Following randomization, patients will begin taking active drug (60µg) orally twice daily. Patients will visit their investigational site at Week 6 and Week 12 for study evaluations.

The primary objective of this study is to evaluate the safety of long-term administration of GSK1325760A in patients with PAH. The secondary objectives of this study are to evaluate long-term administration of GSK1325760A on: Improvement in exercise capacity (six-minutes walk distance: 6MWD), change in WHO Functional Classification and time to clinical worsening of PAH Change in the Borg Dyspnea Index (assessed immediately following the six-minute walk test [6MWT]) Change in plasma brain natriuretic peptide (BNP) levels Cardiopulmonary hemodynamics parameters (as measured by echocardiography)

This is an open-label extension study for patients who participated in the BPS-MR-PAH-201 study.

The main objective of the FUTURE 2 study was to assess the long-term safety and tolerability of the pediatric formulation of bosentan in children with idiopathic pulmonary arterial hypertension or familial pulmonary arterial hypertension who completed FUTURE 1 study.

Active treatment, dose-blinded extension study evaluating the safety and long term efficacy of sildenafil citrate in children with 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.
