Filter by: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 pediatric, adolescent and adult patients with congenital heart disease associated pulmonary arterial hypertension or left ventricular 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.
This trial is a single-center, Phase 1, placebo-controlled, double-blind, multiple-dose study in two ascending dose cohorts of healthy subjects. The primary objective of the trial is to assess the safety and tolerability of multiple doses of MN-08 tablet administered for 6.5 consecutive days in healthy subjects.
Pulmonary arterial hypertension (PAH) is a serious, progressive disease that causes pulmonary arterial pressure, significantly affecting functional capacity and quality of life. Over the last few years, knowledge in pulmonary hypertension has evolved consistently and significantly. New diagnostic and treatment algorithms were combined based on the results of several clinical studies that showed the usefulness of new tools, as well as the effectiveness of new drugs as well as non-pharmacological treatment. The new guidelines felt the benefits of physical exercise in individuals with PAH, with promising results in improving symptoms, exercise capacity, peripheral muscle function and quality of life. With the COVID 19 pandemic, the complex scenario was for world health, and social distancing made it impossible to carry out individual outpatient rehabilitation, in groups and in person, indicating the need for rehabilitation programs, including physical training, to be adapted to the domicile. New alternative modes of pulmonary rehabilitation include home-based models and the use of telehealth. Telerehabilitation is the provision of rehabilitation services at a distance, using information and communication technologies. To date, there has been no evaluation of the clinical efficacy or safety of telerehabilitation in the population affected by PAH.
A proprietary machine-learning algorithm has been developed to model continuous pulmonary artery pressure (PAP), a physiologic marker of cardiopulmonary function. The algorithm was developed from PAP recordings obtained during invasive right heart catheterization. The study will evaluate whether this algorithm can perform as well when embedded into a non-invasive wearable device that records EKG, heart sounds, and thoracic impedance has yet to be established.
Pulmonary hypertension (PH) is a pathophysiological condition defined by an increase in pulmonary arterial pressure above 20mmHg, which encompasses many very dissimilar conditions. Right ventricular function is the major determinant of survival in these patients. Currently, right ventricular function is estimated by trans-thoracic echocardiography via the measurement of standardised parameters. However, cardiac magnetic resonance imaging is now the reference technique for non-invasive quantification of volumes, mass, function of the right ventricle but can also be useful for the consideration of the pulmonary circulation. Thus, indices of function can be extracted and it plays an increasing role in the prognostic evaluation of the right heart function at diagnosis and at re-evaluation under treatment of pulmonary arterial hypertension. This work will initially focus on the assessment of right ventricular myocardial work by echocardiography and cardiac magnetic resonance imaging in comparison with invasive haemodynamic data.
The purpose of this research is to gather information on the safety and effectiveness of a new procedure called Fetoscopic Endoluminal Tracheal Occlusion (FETO).
Throughout the past twenty years, numerous specific pharmacologic agents targeting the endothelial dysfunction associated with PAH have emerged. Short term placebo-controlled randomized trials assessing PAH-specific monotherapy with these molecules have reported improvements in pulmonary hemodynamics and exercise capacity. A recent meta-analysis also documented a reduction in short-term mortality of about ≈40% with such therapies. Several randomized clinical trials evaluating PAH-specific combination therapy have been conducted. Our recent meta-analysis showed that combination therapy was associated with a 35% risk reduction for the occurrence of clinical worsening compared to monotherapy. Nonetheless, the investigators also showed 17% of PAH patients receiving combination therapy still experienced clinical worsening over a median exposure of 16 weeks. Moreover, long-term survival on PAH-specific also therapy remains poor in the modern era, with a yearly mortality rate of 15 % in incident idiopathic PAH. The identification of innovative therapeutic targets and validation of these complementary therapeutic interventions are thus urgently needed in PAH. The investigators and others (K. Stenmark, University of Colorado and H. Bogaard, VU University Medical Center, Amsterdam, personal communications), have published strong evidence that BRD4 plays a key role in the pathological phenotype in PAH accounting for disease progression and showed 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. The overall objective of the study is to explore the efficacy and safety of apabetalone as an add-on therapy for adult PAH patients and to inform the conduct and the design of a Phase 3 trial. The primary objective of the study is to assess the efficacy of apabetalone as evaluated by the change in PVR over a period of 24 weeks compared to placebo in adult subjects with PAH on stable background therapy. Secondary objectives include changes at week 24 in 6MWD, plasma NT-proBNP concentration, WHO functional class, ESC/ERS risk stratification score, health-related quality of life and additional hemodynamic data from right heart. Exploratory objectives are to evaluate the effects of apabetalone compared to placebo in adult subjects with PAH on mortality and clinically relevant morbidity events, and on circulating levels and transcription changes in whole blood markers of metabolism, vascular calcification, inflammation, DNA damage and leucocyte expression of BMPR2.
