The goal of this clinical trial is to evaluate safety and tolerability of preservative-free parenteral treprostinil in paediatric patients with PAH (PH Group 1) who are below 18 years of age. The main question it aims to answer is: • if preservative-free parenteral treprostinil is safe and tolerable in the treatment of paediatric PAH in patients who are either treatment-naïve or have been previously treated with commercially available parenteral treprostinil formulations. Participants will receive either subcutaneous (SC) or intravenous (IV) preservative-free treprostinil and will be observed for 5 months (20 weeks ± 1 week).
This open-label extension study will evaluate the long-term safety, tolerability and efficacy of orally inhaled seralutinib in subjects who have completed a previous seralutinib study
Background. Pulmonary arterial hypertension (PAH) is a heterogeneous pathophysiological condition characterized by progressive pulmonary vascular narrowing that ultimately results in right-sided heart failure and eventually death or lung transplantation. The effectiveness of current pharmacological treatments is suboptimal and a large proportion of patients still had events or died despite receiving combination therapy. Vitamin D deficiency has been found to be much more frequent in PAH patients than in the general population or even compared to patients with other severe cardiovascular diseases. Moreover, vitamin D deficiency has a negative prognostic impact in PAH. Animal studies support that vitamin D deficiency worsens PAH. Hypothesis. In patients with PAH and vitamin D deficiency, restoration of vitamin D status with calcifediol improves their symptomatology and prognosis. Design: Multicenter clinical trial with the participation of 9 hospitals, placebo-controlled, randomized (1:1 ratio), in two parallel groups (without crossover), triple blind, and add-on on existing treatments (add-on). It will include at least 102 subjects (51 in the calcifediol group and 51 in the placebo group) followed for 24 weeks of treatment. Inclusion criteria: Patients of both sexes (18-75 years) with hemodynamic diagnosis of PAH and severe vitamin D deficiency (25-OHvitD <= 12 ng/ml) and without previous diagnosis of osteoporosis or osteomalacia. Treatments: 1) Calcifediol Hydroferol® 0.266 mg once every 10 days for the first 12 weeks and once every two weeks for the following 12 weeks. 2) Placebo. Main objective: A composite endpoint of clinical improvement without clinical worsening at week 24. Expected outcome: Restoration of vitamin D status is an unexpensive measure, very easily implantable and that could improve the evolution of the disease as well as other aspects such as bone or immune health and that has few side effects.
Based on existing literature and clinical trials, 2- hydroxbenzylamine (2-HOBA) has clear impact on mechanisms that much of the international field of pulmonary hypertension (PH) research agrees are central to disease progression. The investigator's preliminary data and Phase I studies demonstrate not only a clear positive impact on reducing pulmonary vascular resistances in Group I and II PH, and both cytokine and molecular biomarkers of disease, but also indicated the potential for a substantial positive effect on heart function under load stress. In this Phase II project, investigators will test the safety and efficacy of 2-HOBA in PH patients, improving the function of the right ventricle under stress in a large animal model, and effectiveness in the context of standard-of-care in mouse models and large animals, to establish the remaining data needed to proceed to commercialization.
The objective of this experimental study is to conduct a comparative evaluation of the effects of a supervised Otago Exercise Program (OEP) functional exercise capacity, blood lactate levels, dyspnea, fatigue, peripheral muscle strength, functional mobility, balance performance, quality of life, sleep status, and comorbidities in adults with pulmonary arterial hypertension (PAH) associated with congenital heart disease (CHD), as compared to a control group. The primary questions driving our study are: - Does the Otago Exercise Program contribute to an increase in functional capacity? - Does the Otago Exercise Program have positive effects on blood lactate levels, dyspnea, fatigue, peripheral muscle strength, functional mobility, balance performance, quality of life, sleep status, and comorbidities? The study participants will be randomly allocated into two groups (n = 50) using a randomized controlled design. The training group (n = 25) will undergo the Otago exercise program, supervised by a physiotherapist, conducted three days a week within a hospital setting for an 8-week intervention period. Following the initial assessment, a patient education session will be administered for the control group (n = 25) and all participants, providing information on disease pathophysiology and the benefits of physical activity. Evaluations will be conducted at baseline and post the 8-week intervention period. Our research project is designed to investigate the effectiveness of the supervised OEP in adults with CHD associated with PAH. Researchers will compare the training and control groups to determine the effects on functional capacity, blood lactate levels, dyspnea, fatigue, peripheral muscle strength, functional mobility, balance performance, quality of life, sleep status, and comorbidities.
The overall study objectives outlined in this study are to derive 129Xe MRI pulmonary vascular biomarker signatures that differentiate common subtypes of PAH and to determine the ability of 129Xe MRI to longitudinally monitor disease progression and response to therapy in PAH, with the aid of additional assessments, such as labs, echocardiography, and six-minute walk distance (6MWD).
IntelliStent is intended to achieve reduction of pulmonary hypertension, improvements in symptoms and quality of life in adolescent and adult patients with congenital heart disease and dilated cardiomyopathy.
To determine whether changes in endothelial cell dysfunction are associated with changes in total pulmonary resistance in patients with pulmonary arterial hypertension
Pulmonary hypertension (PH) is associated with worsening breathlessness and exercise capacity, right-heart failure, and adverse outcomes including increased mortality. Moreover, PH disease progression can be rapid; pharmaceutical intervention in early-stage Pulmonary Hypertension (PH) can improve symptoms and functional capacity, and delayed diagnosis and treatment of Pulmonary Hypertension (PH) likely reduces survival.
