|---|---|
| Main Objective: To compare in Sokal IR/LR CML patients, pretreated with Imatinib for 3 months to CHR, the rate of at least a 3 log reduction in tumor burden (measured with qPCR), after 12 months treatment with imatinib 400 mg daily or imatinib 400 mg daily combined to Peg-IFN 50 µg weekly;Secondary Objective: 1) The rate of 4 log reduction 2) The mean level of minimal residual disease, expressed as K562 equivalents 3) The duration of hematological, cytogenetic and molecular response 4) The rate of molecular progression 5) The timing of molecular response 6) The rate of CCgR 7) The time to ABP 8) The overall survival 9) The safety and tolerability of the treatment. ;Primary end point(s): The rate of at least a 3 log reduction in tumor burden (measured with qPCR), after 12 months treatment with imatinib 400 mg daily or imatinib 400 mg daily combined to Peg-IFN 50 µg weekly | — |
