Primary Endpoint
To determine the maximum tolerated dose (MTD) and recommended dose of dasatinib when combined with imatinib in chronic phase CML patients.

Study Overview

Brief Summary

The purpose of this study is to find out whether adding a new drug, dasatinib, to imatinib is safe, and whether the combination of the two drugs will help decrease the number of cells that contain the Philadelphia chromosome.
