Narrative objectives1

The primary objective of this observational study is to prospectively follow up de novo chronic phase chronic myeloid leukemia (CML-CP) patients and thus to obtain the overview of current treatments of CML and treatment outcomes in Japan. Additionally, minimal residual disease (major BCR-ABL chimera mRNA) will be measured on the International Scale (IS) by quantitative realtime PCR (QRT-PCR) and compared with overseas data. Also, the prognostic values of Sokal score (Sokal score at diagnosis is a known prognostic factor), plasma imatinib level, and BCR-ABL gene mutations for survival outcomes by treatment will be assessed.

Key inclusion criteria

1)CML-CP patients with none of the following signs of accelerated or blast phase CML:
- Blasts more than 15% of peripheral blood white cells or bone marrow cells
- Combined blast/promyelocyte count more than 30% in peripheral blood or bone marrow
- Peripheral blood basophiles more than 20%
- Extramedullary lesions other than hepato-splenomegaly
2)Patients who have given written informed consent to the study; informed consent must also be obtained from the legal representative of every patient under 20 years of age.
3)Patients who will be able to make visits to a study site as scheduled.

Key exclusion criteria

1)Patients previously treated with any investigational drug for CML.
2)Patients previously treated with IFN-alpha.
3)Patients previously receiving any oral cytotoxic drug (e.g., hydroxyurea) for at least 3 months.
4)Women with confirmed or potential pregnancy, nursing mothers, and male or female patients who wish to have a child during the study period.
5)Patients with a history of allergy to imatinib.
6)Patients with any concomitant illness that contraindicates use of imatinib.
7)Patients with any other condition that, in the investigator's opinion, disqualifies them for inclusion in the study.

Other related information

This will be a multicenter, prospective, non-intervention observational (cohort) study involving patients with de novo CML-CP.
The prognostic values of Sokal score (Sokal score at diagnosis is a known prognostic factor), plasma imatinib level, and BCR-ABL gene mutations for survival outcomes by treatment will be assessed.
To minimize site-related biases, the investigators should make every effort to consecutively enroll consenting patients.
