Dose: 75 mg; Dosage form: hard capsules On Days 1, 6 and 17, dabigatran etexilate 75 mg was administered (with midazolam 1mg IV) 1 hour after the planned morning time of givinostat administration. Dabigatran etexilate (and midazolam) was administered following an overnight fasting of at least 8 hours and subjects remained fasted until at least 3 hours post-dose Oral dabigatran etexilate (and oral midazolam) was administered with 150 mL of water.
