Primary outcomePrimary: Number of Participants With Best Confirmed Complete Cytogenetic Response (cCCyR) Within 12 Months — 204; 177 Participants — p=0.0056
Summary
The purpose of this clinical research study is to compare the confirmed complete cytogenetic response of dasatinib with that of imatinib within 12 months after randomization in patients with newly diagnosed chronic-phase Philadelphia positive chronic myeloid leukemia. The safety of this treatment will also be studied.
