Design outcomes

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: starting 15 minutes after injection, for 24 h; Secondary end point(s): The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles. PK endpoints include: • Cmax. • tmax. • The AUC from time zero to 24 h time point (AUC0–24h).

Primary

MeasureTime frame
Main Objective: The primary objective of the study is to characterize inhibition of platelet aggregation (IPA) relative to placebo after a single s.c. injection of ACT-246475 either in the thigh or in the abdomen at 2 different doses in subjects with stable coronary artery disease (CAD) receiving conventional background oral antiplatelet therapy (e.g., acetylsalicylic acid, P2Y12 receptor antagonists).; Secondary Objective: • To assess the pharmacokinetics (PK) of ACT-246475. • To assess the impact of the injection site location (thigh vs abdomen) on the PK and pharmacodynamics (PD) of ACT-246475. • To investigate the impact of concomitant drug use, age, sex, and other covariates on the PK and PD of ACT-246475. • To investigate the safety and tolerability of ACT-246475. ;Primary end point(s): The primary PD endpoint is the PD response that is defined for each subject as a P2Y12 Reaction Units 80%.;Timepoint(s) of evaluation of this end point: starting 15 minutes after injection, for 24 h
