Filter by:This multicenter, open label, single-arm study is aim at investigating the the efficacy and safety of china made ambrisentan in Chinese subjects with PAH.
The purpose of the study is to assess safety and tolerability of prostacyclin receptor agonist formulation in treatment period 1 and with different formulation of prostacyclin receptor agonist in treatment period 2.
The purpose of this study is to examine N-terminal pro brain natriuretic peptide (NT-proBNP) and brain natriuretic peptide (BNP) biomarkers in a number of different settings including assessing the repeatability of laboratory and point of care testing (POCT), the effect of a time delay and exercise have on laboratory measurements. Also to compare the clinical and analytical performances of NT-proBNP and BNP POCT samples across the spectrum of disease severity and finally assess whether POCT in PAH can detect change in patients commencing or escalating PAH treatment.
This multicenter, open label, Phase 2a study is designed to evaluate the effect of inhaled RT234 delivered in a dose escalation manner on the change in pulmonary vascular resistance (PVR) in subjects with Pulmonary Arterial Hypertension (PAH) undergoing Right heart catheterization (RHC). This study is also known as Vardenafil Inhaled for Pulmonary Arterial Hypertension PRN Phase 2a (VIPAH-PRN 2a) study
Rationale: Nutrition and lifestyle interventions are currently not implemented in usual clinical care of PAH-patients. Mainly because there is little known on the relation between pathology, nutrition and lifestyle. Patients who suffer from Pulmonary Arterial Hypertension feel insecure about their nutrition and lifestyle. The investigators hypothesize that an intervention on nutrition and lifestyle can improve the patients' quality of life. Objective: To explore the effect of a nutrition and lifestyle intervention on quality of life for patients suffering from PAH. Study design: Investigator initiated intervention study with control group. Study population: investigators aim to include 70 patients (18 - 80 years) with idiopathic, hereditable or drug related PAH, who have been stable for at least three months and are self-sufficient and/or have a family who's willing to participate in the lifestyle changes. Intervention (if applicable): Nutritional status, - education, - intervention and - compliance. Main study parameters/endpoints: This is an intervention study in which the investigators will asses the effect of a nutrition and lifestyle intervention on quality of life measured by SF-36 overall outcome with a significant difference of 6.35. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The burden for the patient exists of 12 extra visits to the hospital and contact moments, over a period of 11 months, as well compliance to the diet and lifestyle. There is minimal risk in participation.
In this study, the effects of kettlebell exercise training on functional capacity, dyspnea and activities of daily living in patients diagnosed with Pulmonary Arterial Hypertension (PAH) will be investigated.
To evaluate the effect of renal insufficiency on the pharmacokinetics of TPN171H tablets after single dose oral administration, so as to provide basis for formulating clinical medication plan for patients with renal insufficiency; To evaluate the safety of TPN171H tablets in patients with renal insufficiency and healthy subjects
The study aims to investigate and compare the effect of TPN171H on subjects with mild and moderate hepatic impairment compared to healthy subjects.
The primary aim of this study was to evaluate exercise capacity, respiratory muscle strength, pulmonary function, dyspnea and physical activity levels in pediatric PAH patients and compare them with healthy controls. The secondary aim of the study was; To investigate the relationship of dyspnea with exercise capacity, respiratory muscle strength, respiratory functions, physical activity and blood count parameters in pediatric PAH patients.
The aim of the study is that evaluation of basic and accessory respiratory muscles and their relationship of six minute walk test in patient with pulmonary arterial hypertension (PAH)
