Brief Summary

Acute Myocardial Infarction (AMI) is an acute ischemic necrosis that occurs following acute stenosis or occlusion of the coronary arteries, and it is associated with a high morbidity and mortality rate. Acute myocardial infarction typically occurs in middle-aged and elderly individuals, according to the American Heart Association, with the average age of first occurrence being 65.1 years for men and 72.0 years for women. Myocardial infarction (MI) has a significant impact on global health, affecting over 7 million people worldwide annually. In addition, MI can impose a substantial economic burden on society and families. The research study is a Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Phase Ia Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetic Profile, Pharmacodynamics Profile, and Immunogenicity of SGC001 in Healthy Adult Subjects
