Active clinical trials for "Familial Primary Pulmonary Hypertension"

This study aimed to investigate the effects of neuromuscular electrical stimulation on peripheral muscles and other physical and psychosocial variables in patients with pulmonary arterial hypertension. This study was designed as an assessor-blind randomized controlled trial. Thirty-one patients with pulmonary arterial hypertension will be recruited. The participants will randomly divided two parallel groups as treatment and control. For the treatment group, neuromuscular electrical stimulation will be applied to the bilateral deltoid and quadriceps femoris muscles with 50 Hz for 3 days/week, 8 weeks. Control group will not be received any additional treatment, just given healthy life recommendations such as walking. The participants will be assessed before and after the treatment by a blind assessor to the group allocation. The outcome measure will be assessments of the upper and lower limb muscle strength, respiratory muscle strength, muscle cross-sectional area and thickness, pulse wave velocity, exercise capacity, walking speed, functional mobility and balance performances, balance confidence, fatigue perceptions, physical activity level, activities of daily living and quality of life.

Exploring the safety, tolerability, and pharmacokinetic (PK) characteristics of oral TPN171H tablets in patients with Pulmonary Arterial Hypertension under continuous multiple administration conditions, providing a basis for determining the administration plan and recommended dosage in phase II clinical study.

This is a Phase 1B, randomized, participant- and investigator-blinded, placebo-controlled, multi-center clinical trial to evaluate the safety, pharmacokinetics (PK), pharmacodynamics (PD), and biomarkers of inhaled GB002 in adults with World Health Organization (WHO) Group 1 Pulmonary Arterial Hypertension (PAH).

The objective of this randomized control trial is to gain clinical insight on the use of pulmonary artery denervation (PADN) for the treatment of pulmonary arterial hypertension (PAH). The primary objective is to assess effectiveness and safety of PADN for the treatment of PAH.

Pulmonary arterial hypertension (PAH) is a disease where the blood pressure in the pulmonary arteries (PAP) is high. PAH increases the risk of adverse events, including death, during and or after procedures. The severity of baseline PAH correlates with the incidence of major complications, such that those with PAP higher than their systemic blood pressure (SBP) had a 8 fold increased risk of complications. These children present for procedures where an acute exacerbation of their chronic illness-termed Pulmonary Hypertensive (PH)crisis, can occur, often resulting in death if not detected and managed expeditiously. Unfortunately there is little data and no consensus in the pediatric literature on how PH crisis should be managed. --------------------------------------------------------------------------------

Pulmonary Arterial Hypertension or PAH is a progressive condition for which there is no cure. Even with substantial pharmacologic advances in the modern treatment era, survival still remains unacceptably poor, as reported in large PAH registries. Preclinical studies suggest that the administration of allogeneic CDCs have the potential to reduce adverse arteriolar remodeling in PAH which was the basis for the approved investigational new drug (IND). The use of CDCs as an adjunctive therapy in patients comprising 4 sub-groups of patients with PAH in which inflammation and immune dysfunction are key pathophysiologic drivers of PAH.

Pulmonary arterial hypertension (PAH) is a chronic illness characterized by increased pulmonary pressures resulting in right heart failure and premature death. Common symptoms that impair quality of life and functioning are dyspnea, fatigue and sleep disturbance. This trio of symptoms is highly prevalent and forms a symptom cluster (2 or more symptoms that co-occur) in PAH. From a biological, proinflammatory cytokines are implicated in dyspnea, fatigue and sleep disturbance; there is activation of the sympathetic nervous system (SNS) and an inherent inflammatory process in PAH that contributes to the pathophysiology, but the link to this symptom cluster has not been investigated. One novel, treatment for symptom clusters is slow-paced respiration therapy using the FDA-approved device, RESPeRATE. The device contains headphones and a sensor that attaches to the chest to detect inhalation and exhalation. Musical tones synchronize with the respiratory cycle to slowly guide the user to decrease respirations. RESPeRATE moderates effects of the SNS; lowers blood pressure; improves functional capacity and ejection fraction; and significantly decreases pulmonary pressures in left heart failure. The investigators will enroll 10 women with PAH to use the RESPeRATE device to perform slow-paced respiration for 15 minutes per day for 8 weeks to determine the feasibility and effects on the SNS and inflammatory activity and the symptom cluster. The investigator's overall hypothesis is that, as compared to baseline, after eight weeks of therapy women with PAH who receive slow-based respiration therapy will have lower SNS activity and inflammatory levels, and improved dyspnea, fatigue and sleep disturbance.

This clinical investigation is a medical device trial to examine the safety and efficacy of TheraSorb® Ig flex adsorber treatment (as an add-on to conventional treatment) used exclusively with the LIFE 18® apheresis system for extracorporeal application for IA therapy (5 treatments) performed over 5 to 8 consecutive days in patients with Idiopathic Pulmonary Arterial Hypertension and WHO functional classification III.

This study enrolls patients with pulmonary arterial hypertension (PAH) treated with inhaled treprostinil. During the study, the treatment with inhaled treprostinil will be tapered off and simultaneously replaced with an oral treatment (selexipag) targeting the disease in a similar way. The purpose of the study is i) to investigate the safety and tolerability of oral selexipag in patients who transition from inhaled treprostinil, ii) to investigate the effects of oral selexipag on PAH severity and exercise ability before and after transition, and iii) to gain new information about the patients experience taking oral selexipag compared to inhaled treprostinil. Study participants may stay in the study until the FDA has granted marketing authorization.

The purpose of this study was to investigate the effects of QTI571 (imatinib) on pharmacokinetics of bosentan and sildenafil at steady state when co-administered to participants with pulmonary arterial hypertension.
