Modulation of SERCA2a of Intra-myocytic Calcium Trafficking in Heart Failure With Preserved Ejection Fraction — MUSIC-HFpEF  

Heart Failure With Preserved Ejection Fraction Clinical Trial

Official title: A Phase 1b, Pilot Trial Evaluating the Safety and Pharmacodynamic Effects of SRD-001 (AAV1-SERCA2a) in Subjects With Heart Failure With Preserved Ejection Fraction

Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to test an experimental gene therapy in participants with heart failure with preserved ejection fraction, also known as diastolic heart failure. The main questions it aims to answer are:

• safety and tolerability of the gene therapy; and

• whether the gene therapy helps the heart ventricles relax during filling. Participants will undergo a one-time infusion of the gene therapy in the cardiac catheterization laboratory and then be followed for safety and effects on left-sided filling pressures while exercising. The first year will have multiple in-person visits followed by 4 years of biannual phone calls.

Clinical Trial Description

Eligible participants will undergo a one-time antegrade epicardial coronary artery infusion of gene therapy delivered to the 3 major cardiac territories of the left ventricle of the heart (anterior, lateral, inferior/posterior) or bypass grafts unless contraindicated. Post-procedure, the subject will be monitored continuously for a minimum of 4 hours and then discharged to home that same day if medically appropriate. Participants will be followed for 52 weeks as part of the main trial. On Day 2 and Week 1, subjects will be contacted by phone for a general safety assessment, and if clinically indicated, an in-person evaluation and assessment will be performed as soon as possible. On Weeks 2, 4, 12, 24 and 52, subjects will undergo general safety assessments. Additionally, at Weeks 24 and 52, subjects will undergo outpatient core resting and exercise transthoracic echocardiography, right heart catheterization with hemodynamic monitoring and gas exchange measurements, 6-minute wall test, cardiac biomarker testing and completion the Kansas City Cardiomyopathy Questionnaire. Upon completion of the active observation period, participants will continue to be followed for 4 years with bi-annual, semi-structured telephone or in-person questionnaires that collect information on overall status and other comorbid conditions of interest in gene therapy trials. ;
