Study to Assess the Tolerability and the Safety of the Transition From Inhaled Treprostinil to Oral...
Pulmonary Arterial HypertensionThis study enrolls patients with pulmonary arterial hypertension (PAH) treated with inhaled treprostinil. During the study, the treatment with inhaled treprostinil will be tapered off and simultaneously replaced with an oral treatment (selexipag) targeting the disease in a similar way. The purpose of the study is i) to investigate the safety and tolerability of oral selexipag in patients who transition from inhaled treprostinil, ii) to investigate the effects of oral selexipag on PAH severity and exercise ability before and after transition, and iii) to gain new information about the patients experience taking oral selexipag compared to inhaled treprostinil. Study participants may stay in the study until the FDA has granted marketing authorization.
Feasibility of Slow-paced Respiration Therapy for Treatment of a Symptom Cluster in Pulmonary Arterial...
Pulmonary Arterial HypertensionPulmonary arterial hypertension (PAH) is a chronic illness characterized by increased pulmonary pressures resulting in right heart failure and premature death. Common symptoms that impair quality of life and functioning are dyspnea, fatigue and sleep disturbance. This trio of symptoms is highly prevalent and forms a symptom cluster (2 or more symptoms that co-occur) in PAH. From a biological, proinflammatory cytokines are implicated in dyspnea, fatigue and sleep disturbance; there is activation of the sympathetic nervous system (SNS) and an inherent inflammatory process in PAH that contributes to the pathophysiology, but the link to this symptom cluster has not been investigated. One novel, treatment for symptom clusters is slow-paced respiration therapy using the FDA-approved device, RESPeRATE. The device contains headphones and a sensor that attaches to the chest to detect inhalation and exhalation. Musical tones synchronize with the respiratory cycle to slowly guide the user to decrease respirations. RESPeRATE moderates effects of the SNS; lowers blood pressure; improves functional capacity and ejection fraction; and significantly decreases pulmonary pressures in left heart failure. The investigators will enroll 10 women with PAH to use the RESPeRATE device to perform slow-paced respiration for 15 minutes per day for 8 weeks to determine the feasibility and effects on the SNS and inflammatory activity and the symptom cluster. The investigator's overall hypothesis is that, as compared to baseline, after eight weeks of therapy women with PAH who receive slow-based respiration therapy will have lower SNS activity and inflammatory levels, and improved dyspnea, fatigue and sleep disturbance.
Proof of Concept Study of IMMUNOadsorption Therapy in Patients With Idiopathic Pulmonary Arterial...
Idiopathic Pulmonary Arterial HypertensionThis clinical investigation is a medical device trial to examine the safety and efficacy of TheraSorb® Ig flex adsorber treatment (as an add-on to conventional treatment) used exclusively with the LIFE 18® apheresis system for extracorporeal application for IA therapy (5 treatments) performed over 5 to 8 consecutive days in patients with Idiopathic Pulmonary Arterial Hypertension and WHO functional classification III.
BREATHE 5-OL: Tracleer (Bosentan) in Patients With Pulmonary Arterial Hypertension Related to Eisenmenger...
Pulmonary Arterial HypertensionThis 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.
Phase III Randomized Study of UT-15 in Patients With Primary Pulmonary Hypertension
Pulmonary HypertensionOBJECTIVES: I. Determine the safety and efficacy of UT-15 in patients with severe symptomatic primary pulmonary hypertension.
Drug Therapy and Surgery in Congenital Heart Disease With Pulmonary Hypertension
Congenital Heart DiseasePulmonary Arterial HypertensionThe 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%.
Study of Macitentan (ACT-064992) on Morbidity and Mortality in Patients With Symptomatic Pulmonary...
Pulmonary Arterial HypertensionThe 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.
IV Iron Replacement for Iron Deficiency in Idiopathic Pulmonary Arterial Hypertension (IPAH) Patients...
Pulmonary Arterial HypertensionIron DeficiencyThis 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. IV iron formulation used in Europe - Ferinject IV iron formulation used in China - CosmoFer
Iloprost Power 15 in Pulmonary Arterial Hypertension
Pulmonary Arterial HypertensionPatients 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).
Pilot Study of the Safety and Efficacy of Carvedilol in Pulmonary Arterial Hypertension
Pulmonary Arterial HypertensionThe 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.
