Brief summary

The purpose of this study is to learn about the effect of lanabecestat on how the body absorbs and processes dabigatran etexilate and how dabigatran etexilate affects lanabecestat when they are taken together. This study will last about 28 days and participants will be asked to take an lanabecestat tablet daily for 19 days and a dabigatran etexilate tablet on 3 occasions. Screening is required within 30 days prior to the start of the study.
