NCT ID: NCT05117736

Last Updated: 2024-03-13

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: NA
• Total Enrollment: 15 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-03-15
• Study Completion Date: 2023-03-12

Brief Summary

This study is a prospective monocentric, randomized, double-blind, placebo-controlled, crossover clinical trial to assess the efficacy of Sacubitril/Valsartan over placebo in improving exercise capacity and neurohormonal activation in adults with moderate to severe systemic RV dysfunction and NYHA class II or III symptoms.

Detailed Description

Subjects who qualify will be approached and those consenting will be enrolled to undergo a baseline evaluation. An active run-in-phase of 6 weeks will identify each patient's maximal tolerated dose of Sacubitril/Valsartan. Then, each treatment arm (Sacubitril/Valsartan and placebo) will be 24 weeks duration prior to crossover. At the end of each study arm (24 weeks), data regarding primary and secondary endpoints will be collected. The total duration of the study for the patient will be 15 months.

Subjects will undergo regular visits (in-clinic, and/or by phone, or video conferencing) half-way and at the end of each arms.

Conditions

Systemic Right Ventricle; Heart Failure
