Assessment

Primary outcomes

Change in trough of imatinib after up-titration (proportion of subjects achieving an optimal trough level).

Key secondary outcomes

Proportions of subjects achieving MMR and CCyR at 3, 6, 12 and 18 months after up-titration to 600 mg/day, safety of imatinib at 600 mg/day, proportion of subjects continuing treatment at 600 mg/day, and overall survival (OS), progression-free survival (PFS), and event-free survival (EFS) rates at 18 months after enrollment.

Interventions/Control_1

Imatinib will be administered for 18 months at 400 mg (4 tablets) or 600 mg (6 tablets) once daily. If the optimal trough (>=1,002 ng/mL) is not attained at baseline, the dose will be promptly up-titrated to 600 mg/day. If the optimal trough is attained at baseline, treatment with imatinib will be continued at 400 mg/day.
