• Healthy male and female subjects aged between 18 and 65 years (inclusive) at Screening
• Body mass index of 18.0 to 30.0 kg/m2 (inclusive) at Screening
• Systolic blood pressure 100-145 mmHg, diastolic blood pressure 50-90 mmHg, and pulse rate 45-90 bpm (inclusive), measured on the same arm, after 5 min in the supine position at screening and on Day -1 of the first period

Exclusion Criteria:

• Previous exposure to ACT-246475.
• Previous exposure to rifampicin within 3 months prior to Screening.
• Known hypersensitivity to P2Y12 receptor antagonists or rifampicin, or to any of the rifamycins, or any of their excipients
• Loss of 250 mL or more of blood within 3 months prior to Screening
• Any circumstances or conditions, which, in the opinion of the investigator, may affect full participation in the study or compliance with the protocol
• Family or personal history of prolonged bleeding (e.g., after surgical intervention) or bleeding disorders (e.g., thrombocytopenia, clotting disturbances), intracranial vascular diseases, stroke, reasonable suspicion of vascular malformations, or peptic ulcers
• Known platelet disorders (e.g., Glanzmann thromboasthenia, von Willebrand disease, platelet release defect)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area under the plasma concentration-time curve (AUC) from time zero to time t of the last measured concentration above the limit of quantification (AUC0-t)	The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles	Up to 36 hours after treatment administration
Primary	AUC from zero to infinity (AUC0-inf)	The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles	Up to 36 hours after treatment administration
Primary	The maximum plasma concentration (Cmax)	The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles	Up to 36 hours after treatment administration
Primary	The time to reach Cmax (tmax)	The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles	Up to 36 hours after treatment administration
Primary	Terminal half-life (t½)	The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles	Up to 36 hours after treatment administration
