A Real World Study of the Efficacy and Safety of Flumatinib Versus Imatinib in Patients With Newly Diagnosed Chronic Myeloid Leukemia in Chronic Phase

Evaluating the Efficacy and Safety of Flumatinib Versus Imatinib for in Patients With Newly Diagnosed Chronic Myeloid Leukemia (CML)-in Chronic Phase (CP): A Multicenter, Open-label, Real World Study

Flumatinib is an orally available TKI with high selectivity and potency against BCR-ABL1 kinase. It's a multi-center, open-label, real world study to explore the efficacy and safety of Flumatinib versus Imatinib as the first line therapy in patients with chronic myleiod leukemia(CML) in chronic phase(CP).

The purpose of this study is to investigate the long-term efficacy and safety of Flumatinib versus Imatinib in newly diagnosed CML-CP patients to the provide the real world evidence for the clinical treatment of CML-CP in China.

The overall design is a multicenter, prospective, observational study. The study plans to enroll 2,400 newly diagnosed CML-CP subjects.The primary efficacy endpoint is the rate of major molecular response (MMR) , as measured by RQ-PCR at 12 months. Hematologic response, molecular response and cytogenetic response will be assessed at baseline and a certain frequency after treatment, until study completion. (A month is defined as 28 days)

Inclusion Criteria:

1. Men or women aged more than or equal to (≥) 18 years.
2. Patients with Philadelphia chromosome positive chronic myelogenous leukemia in chronic phase (Ph+ CML-CP) within 6 months of diagnosis..
3. Eastern Cooperative Oncology Group (ECOG) performance status: 0~2.
4. Signed and dated Informed Consent Form.

Exclusion Criteria:

1. Patients with previously documented T315I mutation.
2. Received BCR-ABL TKI(s) treatment before enrollment.
3. Any treatment with anti-CML therapy over 2 weeks or hematopoietic stem cell transplantation before enrollment
4. Participated in other clinical trials that might affect the efficacy and safety of CML during this study.
5. Pregnant or lactating female.
