Brief summary

A study to examine the effect of daridorexant on the way the body absorbs, distributes, and gets rid of dabigatran and rosuvastatin in healthy male subjects

Interventions

DRUGDabigatran etexilate

On Day 1 (Treatment A1) and on Day 9 (Treatment C1) a single oral dose of 75 mg dabigatran etexilate will be administered under fasted conditions.

DRUGRosuvastatin

On Day 3 (Treatment A2) and on Day 11 (Treatment C2) a single oral dose of 10 mg rosuvastatin will be administered under fasted conditions.

On Day 7 and Day 8 (Treatment B), on Day 9 and Day 10 (Treatment C1), and on Day 11 through 14 (Treatment C2) subjects will receive 50 mg daridorexant o.d. under fasted conditions.

Inclusion criteria

1. Signed informed consent in a language understandable to the subject prior to any study-mandated procedure. 2. Healthy male subject aged between 18 and 45 years (inclusive) at Screening.

Exclusion criteria

1. Known hypersensitivity to daridorexant, rosuvastatin, and/or dabigatran etexilate, or treatments of the same class, or any of its/their excipients. 2. Any history of hemorrhagic disease, whether or not hereditary. 3. Any history of complications with bleeding after surgery or tooth extractions and/or frequent nasal, hemorrhoidal, or gingival bleeding. 4. Activated partial thromboplastin time (aPTT) and/or thrombin time (TT) \< 0.8 or \> 1.2 at Screening. 5. Clinically relevant findings on the physical examination at Screening. 6.

Clinically relevant findings in clinical laboratory tests (hematology, coagulation, clinical chemistry, and urinalysis) at Screening.

Design outcomes

Primary

MeasureTime frame
Maximum plasma concentration (Cmax) of dabigatranBlood samples for pharmacokinetic analyses will be taken at various time points from Day 1 to 7 and Day 9 to 15 (total duration: 14 days).
Cmax of rosuvastatinBlood samples for pharmacokinetic analyses will be taken at various time points from Day 1 to 7 and Day 9 to 15 (total duration: 14 days).

Other

MeasureTime frame
Area under the plasma concentration-time curve from zero to infinity (AUC0-inf) of dabigatranBlood samples for pharmacokinetic analyses will be taken at various time points from Day 1 to 7 and Day 9 to 15 (total duration: 14 days).
AUC0-inf of rosuvastatinBlood samples for pharmacokinetic analyses will be taken at various time points from Day 1 to 7 and Day 9 to 15 (total duration: 14 days).
Time to reach Cmax (tmax) of dabigatranBlood samples for pharmacokinetic analyses will be taken at various time points from Day 1 to 7 and Day 9 to 15 (total duration: 14 days).
T½ of rosuvastatinBlood samples for pharmacokinetic analyses will be taken at various time points from Day 1 to 7 and Day 9 to 15 (total duration: 14 days).
