Brief summary

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.

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.

Absolute Change From Baseline in Mean KCCQ Score (Overall Summary Score) at Month 6Baseline (Day 1), Month 6Absolute change from baseline in mean Kansas City Cardiomyopathy Questionnaire (KCCQ) score (overall summary score) at month 6 is presented. The KCCQ is a 23-item, self-administered ques-tionnaire developed to independently measure the participant's perception of their health status. Scores range from 0 to 100, with 0 as lowest score and 100 as the highest score. Higher scores indi-cate better health status, fewer symptoms, and greater disease-specific health-related quality of life. The calculation is following the KCCQ scoring manual that states: "Overall Summary Score is defined as mean of the following available summary scores: Physical Limitation Score, Total Symptom Score, Quality of Life Score and Social Limitation Score". Because the manual states that the Overall Sum-mary Score should be calculated on available scores, then if physical limitation score is missing, but other sub scores are available the Overall Summary Score will be calculated anyhow based on other sub scores.
