Prospective, multi-center, open-label, single-arm, Phase 3b extension study of macitentan in patients with PAH. To assess the long-term safety of macitentan in patients with pulmonary arterial hypertension (PAH) beyond treatment in the AC-055-310 study.
Pulmonary 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.
Patients with pulmonary arterial hypertension (PAH) are at much higher risk of death if the RV (right ventricle) is weak. The purpose of this study is to get a better understanding of the factors that determine RV adaptation and how the RV compensates on therapy. The investigator is also interested in how Remodulin (treprostinil) infused over a short period (approximately 48-72 hours) affects the patient's quality of life, medical care, and personal health behaviors. Treprostinil, also known as Remodulin, has been approved by the US Food and Drug Administration for use in the treatment of PAH. The investigator has been treating patients with Remodulin by rapid infusion (over 48 hours) for over 6 years. The investigator would like to establish this practice as safe and effective for the benefit of other centers that treat PAH.
This study assesses the safety and efficacy of bardoxolone methyl relative to placebo in patients with pulmonary hypertension to determine the recommended dose range, evaluate the change from baseline in 6-minute walk distance (6MWD) and determine the effect of Bardoxolone methyl in pulmonary hypertension associated with connective tissue disease, interstitial lung disease, and idiopathic etiologies, including subsets of patients with WHO Group III or WHO Group V PH following 16 weeks of study participation.

An echocardiogram using Definity contrast can provide the same information as the standard right heart catheterization.
The study is a single center randomised, double-blind, placebo-controlled crossover study to assess the effects of beetroot juice in patients with pulmonary arterial hypertension.
The purpose of this study is to see if Lung LLC's new experimental formulation of the medicine Beraprost Sodium, called Beraprost Sodium 314d Modified Release (BPS-314d-MR), can improve the symptoms of pulmonary arterial hypertension (PAH) in patients. An experimental drug is one that has not been approved by the U.S. Food and Drug Administration for use in the general public. This research study is for patients who have pulmonary arterial hypertension (PAH) and have just completed taking part in an earlier research study and received an older experimental formulation of Beraprost Sodium, called Beraprost Sodium Modified Release (BPS-MR). That earlier study was being done to see if BPS-MR could improve their PAH. Patients may also be taking Tyvaso (treprostinil), Tracleer (bosentan), Letairis (ambrisentan), Adcirca (tadalafil) and/or Viagra or Revatio (sildenafil) to treat their PAH. The diagnosis of PAH means that the blood pressure in their lungs is higher than normal. The increased blood pressure in the lungs places a strain on the heart. The strain causes the heart to pump less blood into the lungs, causing shortness of breath and tiredness. The strain on the heart weakens the heart muscle making it less able to pump blood, a condition called heart failure. As heart failure develops, swelling in the feet and abdomen may occur.
Patients with scleroderma can develop heart failure due to high blood pressure in the lungs (a condition called pulmonary arterial hypertension). It is important to find pulmonary arterial hypertension early, so that it can be treated before heart failure develops. However, the tests that we now use to find the earliest form of this disease in scleroderma patients are not good enough. This study will examine whether tests performed during exercise can improve our ability to find early pulmonary arterial hypertension. The study will also try to identify genes that are responsible for the development of pulmonary arterial hypertension.
