Active clinical trials for "Pulmonary Arterial Hypertension"

This is an international, multicenter, randomized, double-blind, placebo-controlled, event driven study in subjects with pulmonary arterial hypertension.

The study was conducted as a placebo-controlled, randomized, 22-week double-blind study which included a dose titration period. An additional transition period occurred for those patients who elected to enroll into the open-label extension study, APD811-007. A total of 61 patients with PAH were enrolled.

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.

This study sought to determine whether terbogrel was an effective treatment for primary pulmonary hypertension (PPH) by comparing its efficacy and safety to that of placebo.

Subcutaneous treprostinil (Remodulin) is effective therapy for pulmonary arterial hypertension, a life threatening disease of the lung blood vessels. Unfortunately, treprostinil is irritating to the skin and many patients experience intense pain at the infusion site for the first 7-10 days after placing a new subcutaneous infusion site. Qutenza is an FDA approved formulation of 8% capsaicin that is approved for the treatment of post-herpetic neuralgia, a painful skin condition. The investigators hypothesize that pretreatment of an area of skin with Qutenza would decrease the pain associated with a new treprostinil infusion site. The investigators hope that Qutenza will decrease both the intensity of the pain and the duration of the pain after patients place a new treprostinil infusion site. In this initial study, the investigators will provide Qutenza in open-label, unblinded fashion and ask patients to rate their pain using a diary tool with which they are already comfortable.

A Phase 2 open label, dose escalation study to find the minimally and maximum effective dose (dose beyond which no further effect on PVR is seen) of inhaled nitric oxide generated by the GeNOsyl® System compared to placebo.

The purpose of this study is to evaluate the effect of esomeprazole, a proton pump inhibitor, on treprostinil pharmacokinetics.

A multinational, multicenter, double blind, placebo-controlled study evaluating the efficacy and safety of imatinib as an add-on therapy in the treatment of patients with severe pulmonary arterial hypertension (PAH).

This study will evaluate the safety, tolerability, and efficacy of imatinib mesylate in patients with pulmonary arterial hypertension

Recent researches indicate that impairment of vascular and endothelial homeostasis plays a major role in the initiation and development of IPAH.We have recently reported the safety and feasibility data for autologous endothelial progenitor cells (EPCs) injection in patients with IPAH. Yet many questions remain unanswered: what is the ideal quantity of EPCs for therapy, the duration of the therapeutic effect, and moreover, the potential toxicity of such therapy. To help answer these questions, we designed the one year follow-up to investigate the safety and efficacy of autologous EPCs injection in patients with IPAH.
