Active clinical trials for "Familial Primary Pulmonary Hypertension"

This study provided/continued to provide oral treprostinil (UT-15C SR; treprostinil diethanolamine) to eligible subjects who participated in Studies TDE-PH-202, TDE-PH-203, TDE-PH-205, TDE-PH-301, TDE-PH-302, and TDE-PH-308. The study assessed the long term safety of oral treprostinil and the effect of continued treatment with oral treprostinil on exercise capacity after 1 year of treatment.

Pulmonary arterial hypertension (PAH) is characterized by the progressive increase in pulmonary vascular resistance leading to shortness of breath and exercise intolerance. Exercise capacity has been used as the primary endpoint in most recent randomized controlled trials evaluating PAH-specific therapies as it correlates with functional class and survival in PAH. Exercise test is commonly assessed by the six-minute walk test (6MWT). However, there is commonly some discrepancy between significant clinical improvement and minor changes (generally <10% from baseline) in 6WMT following therapy. Because important clinical decisions are based on patients' functional capacity, a reproducible and sensitive exercise test is needed in PAH. The aim of this study was to compare the reproducibility and the responsiveness of the 6MWT, the endurance shuttle walk test (ESWT) and the cycle endurance test (CET) following pharmacological therapy in this disease.

A phase 3, randomized, double-blind, placebo-controlled study to assess safety and efficacy of ambrisentan in subjects with pulmonary arterial hypertension.

This 6-month open label study will evaluate the long term safety of bosentan (via oxygen saturation) and efficacy (exercise capacity) in patients who have completed the BREATHE-5 study (PAH related to Eisenmenger physiology). Treatment duration is 6 months.

OBJECTIVES: I. Determine the safety and efficacy of UT-15 in patients with severe symptomatic primary pulmonary hypertension.

The purpose of this study is to test the hypothesis that treating PAH-CHD patients preoperatively with PAH drugs and keeping them on treatment for six months after surgery reduces the risk of immediate postoperative death and the risk of residual PAH at six months following operation to <10%.

This study will establish whether intravenous iron replacement has clinical benefit in idiopathic pulmonary arterial hypertension. A 24-week double-blind, randomised, placebo-controlled, crossover study will investigate whether a single dose of 1g of Ferinject® or CosmoFer improves cardiopulmonary haemodynamics, exercise capacity and quality of life and is well-tolerated.

The AC-055-302/SERAPHIN study will be an event-driven Phase III study, comparing two different doses of macitentan (ACT-064992) (3 and 10 mg) vs placebo in patients with symptomatic PAH. The main study objective is to demonstrate that macitentan (ACT-064992) prolongs time to the first morbidity or mortality event, and to evaluate the benefit/risk profile of macitentan (ACT-064992) in the treatment of patients with symptomatic PAH.

The purpose of this study is to determine whether carvedilol treatment of patients with pulmonary arterial hypertension and associated right heart failure is safe and results in an improved function of the right heart.

Patients with symptomatic idiopathic pulmonary arterial hypertension (IPAH), or familial pulmonary arterial hypertension (FPAH) or pulmonary hypertension associated with Human immunodeficiency virus (HIV) or drugs/toxins in New York Heart Association (NYHA) functional class II to IV at baseline, naive to PAH treatment or currently being treated with a stable dose of either bosentan, ambrisentan or sildenafil will be enrolled in the PROWESS 15 study. This randomized, double blind, placebo-controlled, crossover, and single-dose study will determine whether a single inhaled dose of iloprost using the power 15 disc improves exercise capacity compared to placebo in patients with pulmonary arterial hypertension (PAH).
