A Medical Research Study to Evaluate the Effects of ACT-246475 in Adults With Heart Attack

Summary

The goal of this study is to find out how fast a drug called selatogrel (ACT-246475) can prevent platelets from binding together. This study will also help to find out more about the safety of this new drug. The drug selatogrel (ACT-246475) will be used in 2 different doses (8 mg or 16 mg) and will be administered in the thigh.
