NCT05953831

Brief Summary

This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled study including approximately 130 randomized HF patients with heart failure with mildly reduced or preserved ejection fraction (LVEF ≥45%), to assess efficacy and safety of CDR132L on reverse remodeling. In this study, patients with HFpEF (EF ≥50%) or HFmrEF (LVEF 45-49%) will be included.

Interventions

CDR132L is a synthetic antisense oligonucleotide (ASO) and a selective inhibitor of microRNA-132-3p (miR-132). miR-132 in cardiomyocytes is a central switch affecting the expression of genes that are crucially involved in maladaptive cardiac remodeling, transformation, and pathological cardiac growth (hypertrophy), contributing to adverse cardiac remodeling and heart failure (HF).1-5 Aberrant expression of miR-132 in cardiac cells is causally associated with cardiac remodeling and HF progression.
