This study will randomize patients recently discharged from the hospital with a confirmed diagnosis of type 1 acute myocardial infarction (Thygesen et al. 2018) and having additional cardiovascular risk factors.

Official Title

Multi-center, Double-blind, Randomized, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Self-administered Subcutaneous Selatogrel for Prevention of All-cause Death and Treatment of Acute Myocardial Infarction in Subjects With a Recent History of Acute Myocardial Infarction


The purpose of this study is to assess the clinical efficacy of selatogrel when self-administered upon occurrence of symptoms suggestive of an acute myocardial infarction (AMI) in participants at risk of having a recurrent AMI.
