Overview
Brief Summary
This will be a randomized, open-label, sequential, single dose, 4-period crossover study. This study is being conducted to measure the relative bioavailability of the original gelatin capsule (GC) formulation and two new formulations (hydroxypropyl-methylcellulose [HPMC] capsule and enteric coated tablet [ECT]) of afuresertib (AFU), in the fed and fasted state. The study will be composed of Screening, Treatment, and Follow-up Periods. Screening assessments to determine subject eligibility will be performed within 3 weeks prior to the first dose of study drug in the Treatment Period. Eligible subjects will be randomized to receive 4 of the 6 possible study treatments (A: AFU GC administered in a fasted state, B: AFU GC administered in a fed state, C: AFU HPMC capsule administered in a fasted state, D: AFU HPMC capsule administered in a fed state, E: AFU ECT administered in a fasted state, F: AFU ECT administered in a fed state) in 4 treatment periods (one per treatment period). Subjects will receive a single dose of one of the six study treatments (A, B, C, D, E, F) on Day 1 of each Dosing Period, according to one of the 6 treatment sequences (CEDA, EFAB, ABFC, BDCE, FCBD, DAEF). There will be a minimum of 10 Day washout period between the doses administered in each Treatment Period. A Follow-up visit will be conducted within 10-14 days after the last dose. A subject's total time involved in the study will be approximately 9 weeks. At least 36 subjects will be enrolled in the study, to ensure that at least 6 subjects will be randomized to receive each treatment sequence.
