The purpose of this clinical research study is to compare the rate of complete cytogenetic response of dasatinib to imatinib therapy at 6 months after randomization in chronic phase CML patients. The safety of this treatment will also be studied.
Name: Dasatinib
Name: Imatinib
Allocation: Randomized
Parallel Assignment
There is one SNP
