A Trial of Phosphodiesterase-5 Inhibitor in Neonatal Congenital Diaphragmatic Hernia (TOP-CDH)

Congenital Diaphragmatic HerniaPulmonary Hypertension

Congenital diaphragmatic hernia (CDH) occurs in approximately 1 in 3000 US live births, similar to the incidence seen within the Utah Birth Defects cohort. The diaphragmatic defect compromises lung growth and alters pulmonary vascular development. This is reflected postnatally as respiratory failure, pulmonary hypertension (PH) and overall cardiopulmonary dysfunction, particularly post-repair. Currently, optimal management of post-repair PH remains poorly investigated. Sildenafil citrate is a highly selective phosphodiesterase-5 inhibitor that increases cGMP levels, leading to smooth muscle relaxation and an anti-proliferative effect within the pulmonary vasculature. It is used off-label for many neonatal PH disorders, including PH associated with bronchopulmonary dysplasia and idiopathic persistent PH. Most neonates with CDH born within the Mountain West referral basin are managed at a quaternary care center, Primary Children's Hospital (PCH). Of these neonates with PH, approximately 25% have been treated with off-label sildenafil. However, neither the PCH clinical care group nor others have developed/published a standardized approach for either initiating or discontinuing sildenafil therapy in this group of patients. Thus, the aim of this study is to assess the safety and effectiveness of sildenafil therapy for PH in neonates with CDH within the Utah cohort. Given the relatively short-term outcome and small sample size for this trial, the plan is to use this data to support a larger multicenter randomized trial targeting long-term cardiopulmonary outcomes of infants with CDH and post-repair PH.

Urban-training Intervention in Pulmonary Hypertension (UTHAP)

Pulmonary Hypertension

Pulmonary rehabilitation is effective in the treatment of pulmonary hypertension (PH). However, the beneficial effects of such intervention have been seen to disappear over time in other chronic diseases. The objective of the project is to evaluate the efficacy of an urban exercise program after a rehabilitation program and to identify possible determinants of sustainability of the effect, both in patients and in a murine experimental model. Methodology: 1) Study in humans: randomized study (urban training) in 80 patients with PH. The main variable is the improvement in physical activity measured by accelerometry at 12 months. Improvements in bioimpedance and aerobic capacity will be analysed as secondary variables, as well as possible determinants of vascular function that guarantee the sustainability of the effect (pulse wave velocity, endothelial function, metabolic profile and other plasma biomarkers), and all of them will be correlated with the evolution of the disease (admission due to clinical deterioration). 2) Studies in a murine experimental model: Mice with pulmonary hypertension induced by the administration of SU5416 (sugen) and exposure to hypoxia for 3 weeks will be studied after a three-week rehabilitation program. Half of them will exercise 1-2 days a week for 4 more weeks. At the end of the program, the right ventricular pressure will be measured and subsequently the animals will be sacrificed. Morphometric studies will be performed on lung, cardiac and muscular tissue. Vascular endothelial function and autophagy will be also measured. The differences in these variables between the different experimental groups will be analysed.

A Study of the Efficacy and Safety of MK-5475 in Participants With Pulmonary Arterial Hypertension...

Pulmonary Arterial HypertensionHypertension1 more

This is a two-part (Phase 2/Phase 3) study of MK-5475, an inhaled soluble guanylate cyclase stimulator, in participants with pulmonary arterial hypertension (PAH). The first part (Phase 2) will assess three different doses of MK-5475 compared to placebo in a base period of 12 weeks, followed by comparison of three different doses of MK-5475 during an optional 24 month extension period. The treatment dose with the best efficacy and safety profile in the phase 2 cohort base period will be selected for use in the second part (Phase 3) of the study. The primary hypothesis of Phase 2 is that at least one MK-5475 dose is superior to placebo in reducing pulmonary vascular resistance (PVR) from baseline at week 12. The purpose of the second part (Phase 3) of the study is to confirm the efficacy, safety, and tolerability of MK-5475 at the selected dose compared to placebo during a 12 week base period followed by an extension period of up to 5 years. The primary hypothesis of Phase 3 is that MK-5475 is superior to placebo in increasing 6-minute walk distance (6MWD) from baseline at week 12.
