Brief summary
The objective of this Phase I trial is to demonstrate the bioequivalence of two capsules of dabigatran etexilate made from two different drug product batches. The reference batch is dabigatran etexilate hard capsules 150 mg using the currently approved capsule shell (Qualicaps). The test batch is dabigatran etexilate 150 mg hard capsules using a new capsule shell (Capsugel). The test batch is the drug product intended for future commercial use.

Pre-assignment details
In this crossover study, subjects were randomly assigned to one of the 2 sequences, with 2 treatment arms. In general terms, Ref-Test-Ref-Test and Test-Ref-Test-Ref. The aim was bioequivalence comparing (Ref) Dabigatran 150mg in the currently approved capsule shell (Qualicaps) to the test of Dabigatran 150mg in a new shell (Capsugel).
