Active clinical trials for "Pulmonary Arterial Hypertension"

The purpose of this study is to determine if treating patients suffering from moderate to severe pulmonary arterial hypertension with BSF 208075 will improve the patients' ability to exercise.

This is a double-blind placebo-controlled clinical investigation into the efficacy and tolerability of inhaled treprostinil in patients with severe pulmonary arterial hypertension. The primary outcome is the change in 6-minute walk distance from baseline to week 12.

The purpose of this study is to evaluate the safety and effectiveness of tadalafil for the treatment of pulmonary arterial hypertension.

Open label extension study to the pivotal efficacy study to assess the safety of sildenafil citrate in patients with pulmonary arterial hypertension

the purpose of this study is: to determine the rate and routes of excretion of BIA 5-1058 and the mass balance in urine, feces and exhaled air, after a single oral dose of 400 mg 14C labeled BIA 5 1058 containing 3.7 Megabecquerel (MBq) of radiocarbon; to determine the pharmacokinetics (PK) of total radioactivity (TRA) in plasma and whole blood and to assess the blood-to-plasma ratio; to determine the PK of BIA 5-1058 and its metabolites in plasma.

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%.

6 months therapy of Bosentan, an endothelin antagonist, will lead to improvement in pulmonary microvascular endothelial function.

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 present trial investigates a possible use of oral bosentan, which is currently approved for the treatment of symptoms of pulmonary arterial hypertension (PAH) Class III and IV, to patients suffering from PAH Class II.
