Filter by:The main purpose of this clinical trial is to examine the feasibility and effects of fulvestrant in post-menopausal women with pulmonary arterial hypertension (PAH). The study will evaluate how well the drug is tolerated. The study will evaluate changes in circulating hematopoietic progenitor cells, plasma hormone levels, NT-proBNP, and other plasma biomarkers after the administration of fulvestrant. Changes in tricuspid annular plane systolic excursion, stroke volume index, right ventricular fractional area change, and other echo parameters after fulvestrant administration will be evaluated as well as changes in distance walked in six minutes.
In this study positron emission tomography (PET/CT) imaging will be used to evaluate evaluation of estrogen receptor heterogeneity and functionality in Pulmonary Arterial Hypertension (PAH) using the investigational radiotracer [18F]fluoroestradiol (FES).
This is an open-label, multicenter, parallel, randomized (1:1 Slow Dose Titration Group; Rapid Dose Titration Group), two-group study to evaluate the safety, tolerability, pharmacokinetics and efficacy of slow and rapid dose titration regimens of subcutaneous Remodulin infusion in subjects with pulmonary arterial hypertension (PAH). The study will include about 50 subjects at up to 10 clinical trial centers in China. The treatment phase of the study will last approximately 16 weeks. Subjects who complete all required assessments will also be eligible to enter a long-term open-label, extension study (CVT-CV-004).
To demonstrate the effectiveness of riociguat as replacement of phosphodiesterase-5 inhibitors (PDE-5i) therapy in pulmonary arterial hypertension (PAH) patients
Subcutaneous treprostinil is used to treat pulmonary arterial hypertension (PAH). Due to local pain it causes a deterioration of quality of life or even abandonment of treatment. The aim of this study was to evaluate the safety and quality of life (QoL) in patients treated with treprostinil administration using an implantable Lenus Pro® pump. This is a observational study involving patients with PAH treated with a subcutaneous infusion of treprostinil with intolerable pain at the infusion site, who were therefore referred for pump implantation. Clinical evaluation, including QoL assessment with SF-36 questionnaire was performed at the time of initiating therapy with treprostinil, before and 2-9 months after implantation.
The purpose of this study is to determine the prognostic value of echocardiographic parameters in comparison with clinical and hemodynamic parameters in pulmonary arterial hypertension (PAH). A secondary purpose of this study is to analyze the disease evolution after 3 to 6 months. In pulmonary fibrosis it has been demonstrated that the variation of clinical and paraclinical parameters between 2 examinations has a prognostic interest. In this study the prognostic value of variation of some echocardiographic parameters between initial examination and echocardiography after 3 or 6 months will be evaluated. Another secondary purpose is to create a common database for Pneumology, Cardiology and Epidemiology departments with prospective registration of new cases of PAH and follow of patients under treatment.
The purpose of this study is to learn more about the safety and effects of switching treatments from bosentan (Tracleer) or macientan (Opsumit) to ambrisentan (Letairis) over 24 weeks in subjects with Connective Tissue Disease associated Pulmonary Arterial Hypertension (CTD-PAH).
This is a multicenter, open-label trial to evaluate the safety of continued therapy with subcutaneous Remodulin® in subjects with pulmonary arterial hypertension (PAH) who complete the CVT-CV-003 study. The study will include about 50 subjects at up to 10 clinical trial centers in China who completed all required assessments in the CVT-CV-003 study. Study visits for data collection will occur at month 6 and 12 with yearly visits beyond 12 months until the study is discontinued by the sponsor.
The investigators will investigate the interrelationship of macrophage migration inhibitory factor (MIF) and free T4 in patients with PAH.
The purpose of the study is to evaluate the safety and tolerability of a rapid dose titration regimen of subcutaneous Remodulin® therapy in patients with PAH.
