Brief summary

The primary objective of the trial is to investigate the pharmacokinetics and pharmacodynamics of idarucizumab in Chinese healthy male and female subjects following intravenous administration of idarucizumab followed by idarucizumab with 15 minutes interval when administered at or close to the steady state of dabigatran. Another objective of this trial is to explore the effect idarucizumab on the PK (pharmacokinetic(s)) and PD (pharmacodynamic) parameters of dabigatran.

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.
