Conditions
Brief summary
The study will investigate the effect of rifampicin on the uptake and breakdown of ACT-246475 in healthy subjects
Interventions
Single i.v. infusion of 100 mL saline 0.9% for 30 min
Single s.c. dose of 4 mg ACT-246475 in the thigh under fasting conditions
Single i.v. infusion of 600 mg rifampicin (100 mL) for 30 min

Eligibility
Inclusion criteria
* Signed informed consent in a language understandable to the subject prior to any study-mandated procedure * 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 * Hematology and coagulation test results not deviating from the normal range to a clinically relevant extent at Screening and on Day -1 of the first period * Women of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test on Day- 1 of the first treatment period and must agree to consistently and correctly use a highly effective method of contraception
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)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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) | Up to 36 hours after treatment administration | The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles |
| AUC from zero to infinity (AUC0-inf) | Up to 36 hours after treatment administration | The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles |
| The maximum plasma concentration (Cmax) | Up to 36 hours after treatment administration | The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles |
| The time to reach Cmax (tmax) | Up to 36 hours after treatment administration | The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles |
| Terminal half-life (t½) | Up to 36 hours after treatment administration | The plasma PK parameters of ACT-246475 will be derived by non-compartmental analysis of the plasma concentration-time profiles |
