ALlogeneic Cardiosphere-derived Stem Cells (CDCs) for Pulmonary Hypertension therApy
Pulmonary Arterial Hypertension or PAH is a progressive condition for which there is no cure. Even with substantial pharmacologic advances in the modern treatment era, survival still remains unacceptably poor, as reported in large PAH registries. Preclinical studies suggest that the administration of allogeneic CDCs have the potential to reduce adverse arteriolar remodeling in PAH which was the basis for the approved investigational new drug (IND). The use of CDCs as an adjunctive therapy in patients comprising 4 sub-groups of patients with PAH in which inflammation and immune dysfunction are key pathophysiologic drivers of PAH.
A Long-term Extension Study of Riociguat in Patients With Symptomatic Pulmonary Arterial Hypertension.
To provide riociguat therapy to eligible patients with PAH originating from Bayer-sponsored trials with BAY63-2521/ Riociguat / Adempas® who are currently or recently treated in these trials until lack of patient benefit as assessed by investigator, or commercial availability and reimbursement.
Analysis of the Severity and Prognosis of Pulmonary Hypertension Associated With Bronchiectasis.
Through analysis of demographic factors (gender, age, smoking history and body mass index), clinical indicators (signs and symptoms), sputum culture results (pseudomonas aeruginosa), brain natriuretic peptide and imaging (scope and type of bronchiectasis), pulmonary function index, inflammatory cytokines and inflammasome of patients, some factors will be found which maybe be related to severity and prognosis of pulmonary hypertension associated with bronchiectasis.
Anxiety Self-management Intervention for Pulmonary Hypertension
Pulmonary hypertension (PH) is a disorder of high blood pressure that impacts the heart and lungs. Approximately, 50% of individuals with PH experience anxiety or panic disorders. There is limited evidence on psychological treatments for anxiety in PH; however, results support the use of Cognitive Behavioural Therapy (CBT). Despite the prevalence and impact of anxiety in PH; there are no widely available and/or disease specific pathways, thus highlighting an unmet need in this population. This project aims to develop and pilot, using randomised control trial methodology, a self-management intervention for individuals with PH based on ...
Apabetalone for Pulmonary Arterial Hypertension: a Pilot Study
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. ...
A Phase 3 Adaptive Study to Evaluate the Safety and Efficacy of Inhaled Treprostinil in Participants With Pulmonary Hypertension (PH) Due to Chronic Obstructive Pulmonary Disease (COPD)
The primary objective of this study is to demonstrate the efficacy of inhaled treprostinil compared to placebo in improving exercise ability as measured by change from baseline in 6-Minute Walk Distance (6MWD) following 12 weeks of active treatment in participants with PH-COPD.
Arrhythmias in Pulmonary Hypertension Assessed by Continuous Long-term Cardiac Monitoring
Arrhythmias are considered a prominent phenomenon in pulmonary hypertension (PH) as the disease progresses. According primarily to retrospective studies with up to 24 hours of monitoring, supraventricular tachycardias (SVT) can be found in 8-35% of patients, with significant impact on survival. Furthermore, a few prospective studies to date deploying short-term monitoring (10 minutes-24 hours) have revealed lower heart rate variability (HRV) in patients with pulmonary arterial hypertension (PAH). In ASPIRE arrhythmias and heart rate variability is being assessed via long term monitoring.
Assessment of Cardiac Function Using Combined Cardiovascular Magnetic Resonance and Cardiopulmonary Exercise Testing (CMR-CPET)
What problems limit patients' response to exercise? Using exercise cardiac magnetic resonance imaging to assess the heart's response, with simultaneous measurement of respiratory oxygen and carbon dioxide levels to assess the lung and skeletal muscle responses, to identify the rate-limiting factors affecting different types of patient
Assessment of Continuous Measurement of Transcutaneous CO2 for Evaluation of Alveolar Dead Space During Exercise
The study aim is to monitor, during exercise tests carried out in various conditions, the alveolar dead space, by means of continuous transcutaneous measurement of Pt CO2, which would be used as a surrogate for arterial PaCO2. Validity of this measurement needs to be assessed against arterial sampling (either arterial, or arterialized capillary), especially with regards to the lag time required by the CO2 diffusion from the arterial compartment (PaCO2) to the cutaneous one (PtCO2), in particular when rapid changes of CO2 might be induced by exercise. The evaluation will be done in 2 different settings: - intensive care...
Assessment of the TGF-beta Pathway and Micro-RNA in Pediatric Pulmonary Arterial Hypertension
This is a prospective pilot study to assess the plasma levels of particular proteins involved in the transforming growth factor beta (TGF-β) pathway and its down stream regulators, CHIP, as well as micro RNA molecules in subjects with pulmonary arterial hypertension (PAH) and compare them to control subjects without PAH to see if they can be used as a diagnostic or prognostic marker of PAH and how this compares to other diagnostic biomarkers N-terminal pro-natriuretic peptide (NT Pro-BNP) and C-reactive protein (CRP).
