Study Summary

Two-arm, randomized, open-label trial designed to evaluate the efficacy and safety of bosutinib alone compared to imatinib alone in subjects newly diagnosed with chronic phase Chronic Myelogenous Leukemia (CML). The primary endpoint is cytogenetic response rate at one year.

Primary Outcome

Cytogenetic Response (CyR) is based on the prevalence of Philadelphia chromosome positive (Ph+) metaphases among cells in metaphase on a bone marrow (BM) aspirate. CCyR was achieved when there was 0 percent (%) Ph+ metaphases among cells in a BM sample when at least 20 metaphases from a BM sample were analyzed, or less than (\<) 1% breakpoint cluster region Abelson protooncogene (Bcr-Abl) fusion product among cells in a BM sample or peripheral blood sample when at least 200 cells were analyzed.
