Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE4
• Total Enrollment: 200 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-11-23
• Study Completion Date: 2025-09-30

Brief Summary

It's a double-blind , randomized ,multi-center study. The purpose of this study is to explore the efficacy and safety of flumatinib 400mg once daily (QD) versus 600mg QD as the first line therapy in patients with chronic myleiod leukemia(CML) in chronic phase(CP).

Detailed Description

This is a dose-optimization study of flumatinib in adult patient with newly diagnosed CML-CP. The objective of this study is to compare the efficacy and safety of flumatinib 400mg QD with that of 600mg QD. Eligible patients are randomized in a 1:1 ratio to receive either fluamtinib 400mg QD or flumatinib 600mg QD. Randomization is stratified based on Sokal risk score (<0.8,0.8~1.2,>1.2). Patients will discontinue study therapy due to treatment failure, disease progression or intolerance to study medication or due to investigator's or participant's decision. The primary efficacy endpoint is the rate of early molecular response , as measured by RQ-PCR at 3 months. Hematologic response, molecular response and cytogenetic response will be assessed at baseline and a certain frequency after treatment, until study completion.
