Study to Assess Efficacy and Safety of CDR132L in Patients With Reduced Left Ventricular Ejection Fraction After Myocardial Infarction

This is a Phase 2, multicenter, randomized, parallel, 3-arm, placebo-controlled study to assess efficacy and safety of CDR132L in patients with reduced Left Ventricular Ejection Fraction (LVEF) (≤ 45%) after myocardial infarction (MI). This study consists of a screening period (to occur at least 3 days after MI diagnosis), a 6-month double-blind period, and a 6-month extension period with the End of Study (EOS) Visit at Day 360/Month 12.

Two dosages of CDR132L will be tested against placebo on their effects on patients, who just had a heart attack in addition to standard care. The aim of the study is to show that CDR132L is safe and effective to improve heart failure in such patients.

Treatment and study plan

CDR132L

Drug

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.
