Aim of the study is to compare novel parameters of right ventricle (RV) function from right heart catheterization (RHC) and magnetic resonance imaging (MRI) with PET-derived RV FDG uptake.
Study APD811-303, ADVANCE EXTENSION, is an open-label extension (OLE) study for participants with WHO Group 1 PAH who have participated in another Phase 2 or Phase 3 study of ralinepag.
Pulmonary arterial hypertension (PAH) is a disease characterised with significant morbidity and poor prognosis. Dyspnoea and impaired exercise capacity are very common manifestations of the disease, and result in significant impairment of patients' quality of life. Although hypoxemia is common among subjects with PAH, published data on the effects of supplementary oxygen therapy on specific clinical outcomes among these patients are currently few, while the existing data on the potential benefits of oxygen supplementation to treat exercise-induced hypoxemia, in this patient population, are even more controversial. Based on the aforementioned, the purpose of this prospective, crossover clinical trial is to investigate the acute effects of supplemental oxygen administration on the: a) exercise capacity, b) severity of dyspnea, c) cerebral oxygenation, b) muscle oxygenation, and e) hemodynamic profile, as compared to delivery of medical air (sham oxygen), in a group of patients with PAH, during steady state cardiopulmonary exercise testing (CPET)
This is a multi-center, open-label study for eligible subjects who were actively participating in the BPS-314d-MR-PAH-302 study at the time the study was concluded. This OLE study will evaluate the safety, tolerability and efficacy of long-term treatment of the esuberaprost sodium tablets (Beraprost Sodium 314d Modified Release tablets) study drug.
The main OBJECTIVE of this proposal is to extend the investigator's preclinical findings on the role of epigenetics and DNA damage and Bromodomain-Containing Protein 4 (BRD4) inhibition as a therapy for a devastating disease, pulmonary arterial hypertension (PAH). There is strong evidence that BRD4 plays a key role in the pathological phenotype in PAH accounting for disease progression and that BRD4 inhibition can reverse PAH in several animal models. Intriguingly, coronary artery disease (CAD) and metabolic syndrome are more prevalent in PAH compared with the global population, suggesting a link between these diseases. Interestingly, BRD4 is also a trigger for calcification and remodeling processes and regulates transcription of lipoprotein and inflammatory factors, all of which are important in PAH and CAD. Apabetalone, an orally available BRD4 inhibitor, is now in a clinical development stage with a good safety profile. At this stage, the investigators propose a pilot study to assess the feasibility of a Phase 2 clinical trial assessing apabetalone in the PAH population. The overall HYPOTHESIS is that BRD4 inhibition with apabetalone is a safe and effective therapy for PAH.
The goal of this crossover trial is to determine whether the study drug dehydroepiandrosterone (DHEA) improves right ventricular longitudinal strain measured by cardiac magnetic resonance imaging at 18 weeks compared to placebo and to assess side effects and safety in pulmonary arterial hypertension.
This protocol describes an open-label phase 2 clinical trial of fluoxetine in PAH looking at change in pulmonary vascular resistance (PVR) as the primary endpoint. In this open-label clinical trial, 18 patients with pulmonary arterial hypertension will be randomized to placebo vs. fluoxetine for 24 weeks. A Right Heart Catheterization will be performed at baseline and 24 weeks. Change in PVR will be the primary endpoint; other hemodynamic endpoints, quality of life, QIDS-SR depression scale, functional class and six-minute walk distance will also be evaluated. Primary Hypothesis: Fluoxetine treatment for 24 weeks will lead to significantly lower pulmonary vascular resistance in 18 patients with PAH in patients treated in an open-label clinical trial.
Study APD811-301, ADVANCE OUTCOMES, is designed to assess the efficacy and safety of ralinepag when added to pulmonary arterial hypertension (PAH) standard of care or PAH-specific background therapy in subjects with World Health Organization (WHO) Group 1 PAH.
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.
