The purpose of this study is to demonstrate the bioequivalence of the clinical tablet formulation (100 mg x 5) to the clinical capsule formulation (100 mg x 5) in healthy subjects under fed condition (Cohort 1) and to investigate the effect of a high-fat meal on the pharmacokinetics of bosutinib after administration of the proposed commercial tablet formulation (100 mg x 4) in healthy subjects (Cohort 2).

Condition Intervention Phase
Philadelphia Chromosome Positive (Ph+) Chronic Myeloid Leukemia (CML) Drug: Bosutinib Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, Open-Label, Randomized, Single-Dose, 2-Cohort, 2-Way Crossover Bioequivalence Study To Compare The Bosutinib Clinical Tablet And Clinical Capsule And To Investigate Food Effect On Bosutinib Commercial Formulation in Healthy Subjects
