Company decided not to move forward with this study.

The purpose of this study is to evaluate the safety and clinical efficacy of VM202RY injected via transendocardial route using C-Cathez® catheter (Celyad, S.A., Belgium) in subjects with AMI.

• Stage 1: Evaluation of safety and tolerability of VM202RY injection
• Stage 2: Evaluation of safety and efficacy of VM202RY injection

Ischemic heart disease, a condition in which narrowed or blocked coronary arteries lead to ischemia in myocardium, is a group of disease that include: angina and myocardial infarction.

Acute myocardial infarction (AMI) predicts rapid progression of necrosis. AMI is a serious health condition that it's mortality rate is about 30% and also more likely to have a higher incidence of cardiac dysrhythmia or ventricular aneurysm.

Therapeutic angiogenesis is promising approach for the treatment of cardiovascular disease. 66 to 75% of coronary artery disease patients have insufficient coronary collaterals and 30% of myocardial infarction patients display inadequate myocardial perfusion although there are procedures like percutaneous coronary intervention or coronary artery bypass graft surgery.

In phase I study for ischemic heart disease, VM202RY appeared to have improved regional myocardial perfusion and wall thickness of the diastolic and systolic phases in the injected region. These results suggest that VM202RY improves the myocardial perfusion and inhibits cardiac remodeling in ischemic heart disease patients.

Inclusion Criteria:

1. Age ≥ 19 years to ≤ 75 years

22. Subjects regularly taking cyclooxygenase (COX)-2 inhibiting drug(s) or non-specific COX-1/COX-2 inhibiting drugs, or high dose steroids (except inhaled steroids); subjects may be enrolled if willing/able to undergo medication wash-out prior to the first dosing and to refrain from taking these drugs for the duration of the study, and also if the subject is temporarily taking NSAID (non-steroidal anti-inflammatory drug) temporarily (≤ 7 days)
