Active clinical trials for "Familial Primary Pulmonary Hypertension"

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.

Study A011-09 is designed to assesses the efficacy and safety of sotatercept (ACE-011) relative to placebo in adults with pulmonary arterial hypertension (PAH). Eligible participants will receive study treatment for 24 weeks during the placebo-controlled treatment period, and then will be eligible to enroll into a 30-month extension period during which all participants will receive sotatercept. All treated patients will also undergo a follow-up period after last study drug treatment.

The primary objective of this study is to evaluate the effect of selonsertib (GS-4997) on pulmonary vascular resistance (PVR), as measured by right heart catheterization (RHC) in adults with pulmonary arterial hypertension (PAH). The study will consist of a 24-week placebo-controlled treatment period and a long-term selonsertib treatment period. Participants completing the 24-week placebo-controlled period will be eligible to receive active treatment with selonsertib in the long-term treatment period.

This study will evaluate the safety, tolerability, and PK of MK-8892 in participants with pulmonary arterial hypertension. The primary hypothesis is that the geometric mean of MK-8892 area under the concentration time-curve from Hour 0 to 24 hours (AUC0-24hr) in participants with PAH, will be equal to or greater than the efficacious exposure in humans of 0.6 μM•hr.

This study of MK-5475 in participants with Group 1 pulmonary arterial hypertension (PAH) will assess the safety, tolerability and pharmacokinetics (PK) of inhaled MK-5475. There is no formal hypothesis to be tested.

Actual studies suggest that a calcium activated chlorid channel (TMEM16A) may play a relevant role in the pathogenesis of pulmonary arterial hypertension (PAH). The inhibition of this channel led to pulmonary vasorelaxation in preclinical studies. Benzbromarone is a well known inhibitor of the TMEM16A channel and is used in patients with gout. In this pilot study the investigators plan to investigate if Benzbromarone has an acute effect on the pulmonary arteries in humans. This will be investigated within the frame of a right heart catheterization performed in patients with known PAH due to clinical reasons. The investigators hypothesize that the application of Benzbromarone leads to pulmonary vasodilation, which can be recognized by the decrease in pulmonary vascular resistance. In addition, the change in pulmonary and systemic arterial pressure, pulmonary arterial wedge pressure, heart rate and arterial oxygen saturation will be assessed. Due to clinical reasons patients will receive NO (15 ppm) during right heart catheterization. Hemodynamic changes upon NO and Benzbromarone may be compared.

This proof-of-concept study is designed as a Phase 2, multicenter, randomized, double-blind, placebo controlled study comparing ubenimex with placebo in patients with pulmonary arterial hypertension (PAH) (World Health Organization [WHO] Group 1) and have a WHO/New York Heart Association (NYHA) Functional Classification (WHO/NYHA-FC) of II or III.

The purpose of this study is to evaluate the effects of Coenzyme Q-10, an antioxidant, in the treatment of pulmonary hypertension.

The purpose of this multi-center, open-label, safety and tolerability study was to assess the addition of oral treprostinil (UT-15C sustained release [SR] tablets) to subjects currently receiving Tyvaso (treprostinil) inhalation solution. During the 24-week evaluation period, the study evaluated the changes in the following assessments: hemodynamics, 6-minute walk test (6MWT), Borg dyspnea score, N-Terminal pro-brain natriuretic peptide (NT-proBNP), World Health Organization (WHO) Functional Class, and safety assessments. Eligible subjects had a diagnosis of pulmonary arterial hypertension (PAH), currently were receiving Tyvaso, and may have been receiving other approved PAH specific oral therapies (endothelin receptor antagonists [ERAs] and/or phosphodiesterase type 5 inhibitor [PDE5-I], if at a stable dose for ≥30 days). At Baseline, subjects received the first dose of 0.125 mg UT-15C SR.

The purpose of this study is to see how much study drug is in the blood of children with pulmonary arterial hypertension (PAH) after dosing to establish the correct dose for further clinical research.
