Active clinical trials for "Familial Primary Pulmonary Hypertension"

The purpose of this 8-week study is to compare the effects of switching from intravenous Flolan to intravenous Remodulin therapy. Remodulin (treprostinil sodium) is an approved therapy for pulmonary arterial hypertension (PAH). Unlike Flolan, Remodulin does not need to be mixed daily and is stable at room temperature, so there is no need for ice packs. In addition, Remodulin is changed every 48hrs, instead of every 12-24 (with ice packs) or every 8 hours (without ice packs) with Flolan. Flolan is given using a type of portable medication pump called the CADD Legacy infusion pump. In this study, Remodulin will be given using a smaller and lighter medication pump called the Crono Five infusion pump. This study will also assess the effect that changing to Remodulin will have on treatment satisfaction and patient quality of life.

The main purpose of this study is to evaluate the safety and tolerability of single dose of treprostinil palmitil inhalation powder (TPIP) in participants with pulmonary arterial hypertension (PAH).

This is an exploratory Phase 2a, randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of RVT-1201 in patients with pulmonary arterial hypertension (PAH).

Acute and chronic hemodynamic dose-response and safety evaluation of LIQ861 in PAH subjects.

SYMPHONY Extension is an extension of AC-055-401, a multi-center, open-label, single-arm, Phase 3b study of macitentan in patients with Pulmonary Arterial Hypertension to psychometrically validate the PAH-SYMPACT instrument. The objective is to assess the long-term safety of macitentan in subjects with PAH beyond the treatment in the AC-055-401 study.

Objectives: To test whether the combined administration of the medications treprostinil(a prostacycline therapy), and tadalafil(a PDE-5 [ phosphodiesterase type 5]Inhibitor therapy) is better than the administration of treprostinil alone. This treatment would be offered to newly diagnosed patients with pulmonary arterial hypertension who are on no treatment for this disease and are deemed candidates for the medication treprostinil by their physician. The combination therapy will be compared to single therapy with only treprostinil in a double-blind manner. Current therapy is to begin one treatment, either a PDE5 inhibitor or a prostacycline, depending on the severity of the patient's PAH (pulmonary arterial hypertension) disease and add additional therapies as deterioration occurs. This treatment could add two agents initially. Secondary objectives are: To improve pulmonary arterial pressures as measured through a cardiac echocardiogram, improve the subject's 6minute walk distance, delaying the time to clinical worsening, and lowering plasma BNP levels. Research Procedures: To begin the administration of both treatments at the same time. Time period is 16 weeks with a one- year follow-up. Cardiac Echocardiograms, clinic physician exams, and lab work will be followed. Subjects will be between the ages of 18 - 75.

Prospective, multi-center, open-label, single-arm, Phase 3b psychometric validation study. Primary objectives: To evaluate the psychometric characteristics of reliability and construct validity of the French, Italian and Spanish versions of the PAH-SYMPACT™. To evaluate the ability of the French, Italian and Spanish versions of the PAH SYMPACT™ to detect change. Secondary objective: To assess the safety of macitentan in patients with pulmonary arterial hypertension (PAH). Exploratory objective: To explore the effects of macitentan on PAH symptoms and their impact (as measured by the PAH-SYMPACT™) in patients with PAH in France, Italy and Spain.

The purpose of this study is to find out if spironolactone added to ambrisentan for Pulmonary Arterial Hypertension (PAH) will increase exercise capacity. We also want to find out if spironolactone and ambrisentan effect the cardiac output (amount of blood the heart pumps every minute), right ventricle function and quality of life.

This study assesses the safety and efficacy of bardoxolone methyl relative to placebo in patients with connective tissue disease-associated pulmonary arterial hypertension to determine the recommended dose range and evaluate the change from baseline in 6-minute walk distance (6MWD) following 24 weeks of study participation.

The purpose of the study is to document the effect of first line dual oral combination therapy with macitentan 10mg and tadalafil 40mg on pulmonary vascular resistance (PVR) in treatment-naïve patients with newly diagnosed pulmonary arterial hypertension (PAH).
