Active clinical trials for "Hypertension, Pulmonary"

Selexipag is available in many countries for the treatment of pulmonary arterial hypertension (PAH). Due to the similarities between PAH and chronic thromboembolic pulmonary hypertension (CTEPH) and the observed efficacy of other PAH medicines in CTEPH, it is believed that selexipag could benefit to patients with CTEPH. This study aims to assess the efficacy and safety of selexipag in participants with inoperable or persistent/recurrent CTEPH.

A randomized, double-blind, placebo-controlled dose escalation and verification study to assess the safety and efficacy of pulsed inhaled nitric oxide (iNO) in subjects at risk for pulmonary hypertension associated with pulmonary fibrosis on long term oxygen therapy (Part 1 and Part 2) - REBUILD

This study looks to develop a multi-scale computational model of Pulmonary Hypertension, this clinical model will be calibrated using longitudinal, retrospectively and prospectively acquired human clinical data.

A 6-month (24-week), randomized, open label evaluation of the safety, tolerability, and efficacy of a high and low dose ambrisentan (adjusted for body weight) treatment group in subjects aged 8 years up to 18 years with pulmonary arterial hypertension (PAH). An additional objective is to determine the ambrisentan population pharmacokinetics in the paediatric population. The study will include a screening/baseline period and a treatment period. The treatment period will be 24 weeks or until the subject's clinical condition deteriorates to the point that alternative/additional treatment is necessary. Patients who participate in the study and in whom continued treatment with ambrisentan is desired will be eligible to enrol into a long term follow-up study. The primary comparison will be the safety and tolerability of the two ambrisentan dose groups (Low vs. High) in the paediatric PAH population The secondary comparison will be the change from baseline for the efficacy parameters between the two treatment groups.

A 3-month open label study to evaluate the safety and efficacy of PRX-08066 in patients with pulmonary hypertension and COPD.

The purpose of this study is to find out if the drug, Gleevec, is safe and effective in treating children with Pulmonary Hypertension.

This prospective, randomized controlled trial tested whether initiating iNO therapy earlier would reduce death and reduce the use of extracorporeal membrane oxygenation (ECMO) -- temporary lung bypass -- therapy compared with the standard recommendation threshold. Infants who were born at >34 weeks' gestation were enrolled when they required assisted ventilation and had an oxygenation index (OI) >15 and <25 on any 2 measurements in a 12-hour interval. Infants were randomized to receive either early iNO or to simulated initiation of iNO (control). Infants who had an increase in OI to 25 or more were given iNO as standard therapy. The neurodevelopment of the subjects were evaluated at 18-22 months corrected age.

Study ROR-PH-302, ADVANCE CAPACITY, is designed to evaluate the effects of ralinepag therapy on exercise capacity as assessed by change in peak oxygen consumption (VO2) derived from cardiopulmonary exercise testing (CPET) after 28 weeks of treatment

This is a randomised, double-blind, placebo-controlled, multicentre, multinational, prospective study in patients with operable chronic thromboembolic pulmonary hypertension (CTEPH) prior to pulmonary endarterectomy (PEA) with high preoperative pulmonary vascular resistance (PVR). Patients will be randomised in a 1:1 ratio to receive riociguat or matching placebo for 3 months before undergoing PEA. The primary objective of this study is to assess the efficacy of riociguat on preoperative PVR compared to placebo in patients with operable CTEPH.

Chronic pulmonary hypertension (cPHT) is a serious cardiopulmonary disorder that causes low oxygen levels in the blood, difficulty in breathing and ultimately heart failure. Newborn babies born extremely premature frequently suffer from cPHT while receiving treatment in neonatal intensive care units and are more likely to die than those without cPHT. Echocardiography is the investigation of choice for the assessment of heart function in premature infants however however there is a significant lack of standardization, sensitivity, and reliability for echocardiography parameters and a lack of consensus regarding optimal detection timing. In adults and older children it is known that early diagnosis and treatment, particularly before right side of the heart fails, is an important determinant of treatment success and survival. Diagnosis late in postnatal course for preterm infants remains a major barrier to timely and effective treatment. The primary objective of this study is to develop new, sensitive, quantitative echocardiographic diagnostic criteria which will allow for the identification of extreme preterm neonates suffering from significantly high pressure in their pulmonary blood vessels, early in postnatal course, when the disease is likely to be most amenable to preventative/curative treatment. This is an international initiative that will leverage expertise about echocardiography techniques and cardiopulmonary physiology of preterm infants.The results of this study will have an immediate impact on the day-to-day care of these highly vulnerable infants. The results will lead to increased awareness among clinicians, inform future surveillance protocols and diagnostic timing, and provide ideal preparation for future therapeutic trials.
