Active clinical trials for "Hypertension, Pulmonary"

The purpose of the Phase 2a study is to: 1) demonstrate that the estimated VentaProst dose is safe and equivalent in effect to a dose administered via epoprostenol aerosolization by the current off-label-use practice; and 2) demonstrate that an optimum effect can be rapidly obtained with VentaProst titration.

Oral selexipag is commercially available in several countries for the treatment of a particular group of pulmonary hypertension (PH) called pulmonary arterial hypertension (PAH). The aim of the present study is to investigate whether selexipag could be helpful to treat patients with another form of PH called sarcoidosis-associated pulmonary hypertension (SAPH).

GSK2586881, a purified intravenous (IV) formulation of soluble recombinant human Angiotensin Converting Enzyme (rhACE2) is being investigated as a treatment for PAH. This GlaxoSmithKline (GSK) study will evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GSK2586881 in subjects with PAH. This open-label, dose-escalation study will comprise of 4 separate groups based on the planned dose range, and subjects in each group will be administered a single dose of GSK2586881 ranging between 0.1, 0.2, 0.4 and 0.8 milligram per kilogram (mg/kg) via IV route. Dose escalation will occur after 4 subjects have been dosed per cohort and review of safety, tolerability, PK and hemodynamic data up to 24 hours post dose has taken place. A maximum of 27 subjects will be included in the study and the total duration of the study will be up to a maximum of 59 days.

In this study effect of NHF on pulmonary thermodynamic parameters will studied.

The aim of this pilot randomized controlled blinded study is to evaluate the feasibility of using nebulized magnesium sulfate in the treatment of PPHN.

Background Hospital-based walking exercise tests are routinely used in patients with pulmonary hypertension to assess functional ability and disease progression over time. We are seeing a greater emphasis on non-face-to-face clinical assessments, where such tests cannot be conducted. It is important to identify alternative tests which can be which can be conducted by patients at home and used to support clinical decision making. Aim To test the safety of the 1-minute sit-to-stand test in patients with pulmonary hypertension and its comparability with hospital-based walking exercise tests. Methods A sample of 75 patients attending hospital appointments will carry out an Incremental Shuttle Walk Test, followed by a 1-minute sit-to-stand test after a 30 minute rest. Data will be analysed for safety and comparability between the 2 tests. In the event of favourable findings (safety and comparability) from the hospital-based testing, a further sample of patients will be asked to perform the 1-minute sit-to-stand test in the home setting

This is a single center, open-label, randomized, single-dose, three-period cross-over study in healthy participants. The aim of this study is to provide clinically relevant information on the pharmacokinetic (PK) and safety profile of a new lower dose formulation ambrisentan (AMB) tablet, which is intended for pediatric use. The study will compare the relative bioavailability of the lower dose tablet, dispersed in water and administered orally, with the reference marketed AMB tablet in healthy adults. The total study duration for each participant is expected to be approximately 9 weeks.

Pulmonary hypertension (PH) is a consequence of an increase in pulmonary vascular resistance (PVR), pulmonary blood flow, pulmonary venous pressure, or a combination of these elements. Pulmonary arterial hypertension is a frequent complication of congenital heart disease, particularly in patients with systemic-to-pulmonary shunts. Persistent exposure o f the pulmonary vasculature to increased blood flow and pressure may result in vascular remodeling and dysfunction. This leads to increased pulmonary vascular resistance and, ultimately, to reversal of the shunt and development of Eisenmenger's syndrome. It may be more appropriate to define pulmonary hypertension according to the ratio of MPAP to mean systemic arterial pressure (MPAP/MAP) because children may have a low mean systemic blood pressure. MPAP/MAP ratio of < 0.25 is normal, a ratio of 0.33-0.5 indicates moderate pulmonary hypertension, and a ratio of > 0.5 is indicative of severe pulmonary hypertension

This was a multicenter, randomized (1:1 inhaled treprostinil: placebo), double-blinded, placebo-controlled trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with interstitial lung disease (ILD) including combined pulmonary fibrosis and emphysema (CPFE). The study included 326 patients at approximately 120 clinical trial centers. The treatment phase of the study lasted approximately 16 weeks. Patients who completed all required assessments were eligible to enter an open-label, extension study (RIN-PH-202).

To study the acute effect of acetazolamide (AZA) on pulmonary hemodynamics in patients with pulmonary hypertension (PH) undergoing clinically indicated right heart catheterisation (RHC).
