Participant Flow

A total of 20 participants who met all inclusion criteria and no exclusion criteria were enrolled from 28 Aug 2020 to 20 Oct 2020 at 1 clinic in the United States.

This study consisted of two treatment periods. Following a Screening Period of 21 days, eligible participants received only dabigatran etexilate (Reference Treatment) on Day 1 of Period 1 followed by quizartinib and dabigatran etexilate administration (Test Treatment) on Day 5 of Period 2.
