A Study to Investigate Safe and Tolerable Dose of GMA301 Injection in Healthy Volunteers
This study is a single-centre, randomized, double-blind, placebo-controlled, dose escalation study to assess the safety, tolerability and PK of GMA301 Injection in healthy subjects. Two sequential dosing cohorts (at ascending dose fashion), each with 6 subjects receiving GMA301 Injection and 2 subjects receiving placebo (total of 16 subjects), will be given single doses. The doses to be administered in the two cohorts will be 1500 mg and 2000 mg respectively, or matching placebo
A Study to Investigate the Efficacy of PADN to Improved Functional Capacity and Hemodynamics in Patients With PAH
Pulmonary arterial hypertension (PAH) is characterized by premature death mainly because of progressive and severe right ventricular failure. Target drugs are reported to be associated with significant improvement of clinical outcome for PAH patients. However, previous studies using those target drugs focused on the change of 6-minute walk distance (6MWD) and or hemodynamic responses. As 6MWD has weak correlation with clinical outcome (time to clinical worsening, TTCW), benefits from target drugs for PAH patients are not clear. We previously reported the safety and efficacy of pulmonary artery denervation (PADN) for treatment of PAH ...
A Study to Test the Effects of Riociguat in Patients With Pulmonary Hypertension Associated With Left Ventricular Systolic Dysfunction
The aim of this study is to assess whether increasing oral doses of Riociguat are safe and improve the well-being, symptoms and outcome in patients with pulmonary hypertension associated with left ventricular systolic dysfunction
A Systematic Review of Factors Associated With Pulmonary Arterial Hypertension in Systemic Sclerosis
This protocol is of a systematic review for risk factors of pulmonary arterial hypertension in systemic sclerosis.
Autologous Stem Cell Transplantation in Patients With Systemic Sclerosis
The purpose of this study is to determine whether a regimen of high-dose immunoablative therapy will demonstrate safety that is consistent or improved with other published regimens in SSc patients, while maintaining a treatment effect. We also hypothesize that our mechanistic studies will yield biomarkers that may herald disease recurrence or progression following alterations in the recovery of immune cells in the skin and/or bronchial lavage or blood.
Biomarkers in Pediatric Congenital Heart Disease and PAH
Nowadays, biomarkers are broadly used in clinical practice. Blood-derived biomarkers fulfil an important role in the field of cardiology. However, most biomarkers have been investigated for adult left ventricular disease. In congenital heart diseases (CHD) and pulmonary arterial hypertension (PAH), which involves children and mostly the right ventricle, less is known about the clinical and predictive value of blood-derived biomarkers. Since the group of survivors of CHD and PAH is growing because of the improved techniques nowadays, development of better tools to maintain the quality of life for the longer term in these patients is ...
Bleeding Frequency Under Anticoagulant Treatment in Pulmonary Hypertension
Pulmonary hypertension (PHT) patients often receive long term oral anticoagulants. If the indication is strong, in the secondary chronic thrombo-embolism pulmonary hypertension (CTE-PHT) prevention, the frequent prescription (50 to 90% of patients) contrasts with their low level of proof in the PHT. Last but not least, anticoagulants are known to be the principal cause of iatrogenic hospitalization (major bleeding). In this study, patients are all followed during one year, to determine the annual frequency of major bleedings (according to the International Society on Thrombosis and Haemostasis (ISTH) international definition). Each...
BMPR2 Mutations and Iron Metabolism in Pulmonary Arterial Hypertension
Previously characterised PAH patients, including idiopathic, heritable and other forms of group 1 PAH with and without BMPR2 mutation which have already been analysed and are regularly seen in the Center for Pulmonary Hypertension may be contacted to participate in the study. Clinical and laboratory values will be collected prospectively. Patients with IPAH/HPAH and other forms of PAH who are newly diagnosed within the duration of the trial will receive routine diagnostic workup including the routine information about a possible BMPR2 mutation analysis for IPAH/HPAH patients according to guidelines. During their routine visit the...
Cardiac Assessment by PV Loop in IPAH and Scleroderma PAH
This observational study is being done to understand why people with scleroderma can develop pulmonary arterial hypertension (high blood pressure in the lungs, abbreviated PAH) and a weak heart muscle (heart failure). The study will also help the investigators understand why people with PAH from an unknown cause (called idiopathic PAH, or IPAH) can also develop a weakened heart muscle. The response of the right side of the heart or right ventricle (RV) to standard PAH therapy in scleroderma-associated PAH and in IPAH will be assessed. Blood and tissue samples will be collected from research participants during participants' normal ...
Cardiac Function and Exercise Capacity in Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension is characterized by a progressive increase in pulmonary vascular resistance inducing shortness of breath and exercise intolerance. We aim to correlate cardiac function (evaluated at rest by right heart catheterism and RMN) to exercise capacity (evaluated by endurance time at 75% of maximal workout), in prevalent patients with pulmonary arterial hypertension, and their evolution at three and twelve months.
