Filter by:This prospective, observational, multi-center, patient registry will follow patients who are newly initiated on Tyvaso for the treatment of Pulmonary Arterial Hypertension (PAH). Once enrolled, the patients' dose and titration will be followed for the first 6 months of treatment with Tyvaso. A call-center will contact the patients directly at weeks 1, 2, 3, 4, 8, 12, 16, 20, and 24 to review their dose and titration schedule. In addition to patient-reported dosing data, some patient demographic information, will be collected by the investigative site at Baseline.
This study will evaluate safety, tolerability and effects on central diastolic blood pressure (cDBP) of MK-8892 given as single oral doses in healthy male participants (Panel A and B) and in male participants with mild-to-moderate hypertension (Panel C).
The purpose of this clinical study is to assess the safety of PLX-PAD to treat pulmonary arterial hypertension (PAH). PLX-PAD is a cell-based product made of allogeneic Mesenchymal-like Adherent Stromal Cells (ASCs), derived from human full-term placentas following an elective caesarean section. This year-long study will evaluate the safety of three different dose levels of PLX-PAD, each given as a single intravenous infusion. This study will also evaluate effects that PLX-PAD may have on PAH, such as changes in the ability to exercise and on other tests used to measure the disease severity.
Develop a brief, new, patient reported outcome instrument that is valid for use in clinical practice and clinical trials.
This prospective, non-interventional, multi-center study documents observational data on subjects under routine treatment of Pulmonary Arterial Hypertension, functional class III with inhaled Iloprost administered with I-Neb AAD (Adaptive Aerosol Delivery) device. The observation period for each subject covers a one year treatment period with inhaled Ventavis. For each subject, the investigator or a delegate collects data as defined in the case report form at an initial visit, routine follow-up visit at 6 months and final visit at 12 months.
The purpose of this study is to assess the safety of ranolazine in people with pulmonary arterial hypertension (PAH) and who are receiving 1 or more background PAH therapies: ambrisentan, sildenafil,tadalafil, epoprostenol, treprostinil (IV, SC, inhaled), or iloprost. The primary objective is: - To estimate the effect of ranolazine administration on acute hemodynamics. - To assess safety of ranolazine acutely over 6 hrs in the catheterization lab and after 12 weeks of therapy - To assess changes in right ventricular function after 12 weeks of therapy.
Clinical study to assess the efficacy, safety, and tolerability of macitentan in subjects with Eisenmenger Syndrome.
Long-term study to evaluate if macitentan is safe, tolerable and efficient enough to be used for treatment of Eisenmenger syndrome.
Background: - High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. Some people have disease-associated PAH and some have PAH from an unknown cause. Researchers want to follow the natural history of all PAH patients to understand how PAH progresses in order to discover targets for future research into new treatments. To further identify treatment targets, they will compare healthy volunteers to patients with PAH. Objectives: - To study the natural history of PAH. Eligibility: - Individuals at least 18 years of age who have PAH. - Healthy volunteers at least 18 years of age. Design: - Participants with PAH will have periodic visits to the National Institutes of Health Clinical Center. After the first visit, they will return in 6 months and then yearly or every other year for as long as the study continues. - The first visit will take up to 3 days. It will involve the following tests: - Physical exam and medical history - Blood and urine samples - Heart and lung function tests and imaging studies - Six-minute walk test - Questions about exercise and physical activity - Healthy volunteers will have only one visit to the Clinical Center, during which they will undergo screening tests, and complete many of the same tests as patients with PAH
The AIR001-CS05 study evaluated the safety and efficacy (effectiveness) of AIR001 over 16 weeks in subjects who have PAH. The purpose of the AIR001-CS06 study is to evaluate the intermediate / long-term safety of AIR001 in subjects who have completed the AIR001-CS05 study. Assessments to evaluate the effectiveness of the study drug will include measurements of exercise ability and evaluations of PAH disease symptoms.
