Comparison of the Relative Oral Bioavailability of GKT137831 Formulated in Capsules or in Tablets

Study Overview
=================
Brief Summary
-----------------
The study will be a comparative oral bioavailability study between GKT137831 capsules and tablets, together with an assessment of the impact of concomitant food intake on the relative bioavailability of GKT137831 tablets. This will be a randomized three-way open cross-over study.
