Participant Flow

This was a single-centre, open-label trial in 1 group of healthy volunteers. The trial included a 2-week treatment period during which the subjects were hospitalised at the trial site and a follow-up period of approximately 3 months.

Healthy male and female volunteers, aged ≥18 and ≤45 years, body weight ≥50 kilograms (kg) with a Body Mass Index (BMI) in the range from ≥19 to \<24 kilogram per square meter (kg/m2) were included in the trial.

Measure
Dabigatran Etexilate+Idarucizumab
During the first part of the treatment period, dabigatran etexilate was administered alone. All subjects received 220 milligram (mg) dabigatran etexilate (capsule) orally twice daily for 3 days (from Days 1 to 3) and a single 220 mg dose on Day 4. During the second part of the treatment period, after a washout period of 3 days, subjects again received dabigatran etexilate (capsule) orally twice daily for 3 days (from Days 8 to 10) and a single 220 mg dose on Day 11. Idarucizumab (solution for infusion) 2 short infusions of 2.5 grams (g) each, with a 15 minute (min) interval was administered intravenously approximately 2 hours (h) after the last dabigatran etexilate administration.
