Patients with chronic myeloid leukemia in imatinib induced CHR are randomized between imatinib 400 mg daily and imatinib 400 mg daily + PegIntron 30 ug weekly.

Primary endpoint: To compare at 12 months between the treatment arms the rate of Major Molecular Response (=99,9% tumour reduction) at 12 months
