NCT07172334
Pulmonary arterial hypertension (PAH) is a rare and incurable disease affecting people of all ages. It is characterized by obstructive remodeling of the small pulmonary arteries, responsible for an increase in pulmonary arterial pressure, leading to right heart failure and death in the absence of treatment. PAH can be associated with a variety of diseases, but around half of all PAH cases are idiopathic or hereditary, and may develop on predisposed terrain following a "second hit", as suggested by the identification of PAH cases associated with the use of anorectic drugs, methamphetamine and occupational exposure to organic solvents. No study has systematically analyzed the exposome of patients with PAH, combining environmental and occupational exposures as well as drugs and medications. The exposome of patients with PAH without associated causes will be compared with that of patients with another form of pulmonary hypertension (PH), linked to thromboembolic risk factors: chronic thromboembolic PH (CTEPH), which will constitute the control group.
NCT07266519
The study aims to see how 24 weeks of triple therapy-an endothelin receptor antagonist (ERA), a phosphodiesterase-5 inhibitor (PDE5i), and sotatercept-affects pulmonary vascular resistance (PVR) in patients with newly diagnosed pulmonary arterial hypertension (PAH). SIRIUS is a 24-week, single-arm, open-label study with up to 42 days of screening and a 28-day safety follow-up. It will enroll 25 patients and will be conducted only in countries where all treatments are available and covered. After 24 weeks, PAH treatment is decided by the doctor.
NCT07232368
This study aims to investigate the effects of slow-paced breathing (SPB) intervention applied to patients with pulmonary arterial hypertension (PAH) in the home environment on symptom management (dyspnea, fatigue, sleep quality), clinical parameters (Six-Minute Walking Test-6MWT), IL-6, NT-proBNP results) and quality of life.
NCT01347216
In view of the manifold options for mono- and combination therapy that have now emerged for patients with pulmonary (arterial) hypertension (PH/PAH), controlled clinical trials can only provide part of the information needed for optimal management. In order to gather adequate data on PAH/PH treatment in routine clinical care, the ongoing COMPERA registry prospectively documents consecutive patients with newly initiated treatment of PAH/PAH since May 2007. The internet-based registry fulfills high quality standards through several measures (planned minimum centre contribution of at least 10 patients per year, automated plausibility checks of data at entry, queries, monitoring with source data verification in \>50% of participating centers). It can be applied, among further purposes, for quality assurance: individual centers can confidentially compare their results with the combined outcome of other centers and the recommendations from guidelines. It is expected that the register contributes to optimization of specific drug therapy for PAH and PH. Since July 2013, also children of any age can be documented (COMPERA-KIDS).
NCT07082933
This is a multicenter retrospective cohort study on pulmonary arterial hypertension. It is expected to collect data from no less than 5,000 patients to compare the long-term overall survival of patients with and without diabetes, and analysis the risk factors of the overall survival .
NCT06932198
Randomized, single oral dose, two-period, two-treatment, two-sequence open-label, crossover, bioequivalence study to compare Selexipag 400mcg Film Coated Tablets (400 mcg Selexipag) versus Uptravi® 400mcg Film Coated Tablets (400 mcg Selexipag), in healthy subjects under fed conditions.
NCT03362047
Pilot study to determine the therapeutic effect of two prarallel groups treated with either Riciguat or Macitentan, evaluated by the change in systolic and diastolic RV function within 12 weeks after first drug intake in order to plan a larger Phase II study.
NCT03523910
The goals of this study were two-fold. First, the attempt to quantify the relationships between pulmonary arterial stiffness, right ventricular function and the efficiency of ventricular-vascular interactions in patients with pulmonary arterial hypertension (PAH). Second, the attempt to quantify the effects of exercise on pulmonary arterial stiffness, pulmonary vascular resistance, right ventricular function and the efficiency of ventricular-vascular interactions in patients with PAH.
