Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Imatinib Mesylate at a dose of 400 mg / day is the standard treatment for patients with CML-CP. Recent studies show that the quality of response rate (complete cytogenetic response and major molecular response rate) is dependent on the residual plasma Imatinib.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Imatinib Mesylate at a dose of 400 mg / day is the standard treatment for patients with CML-CP. Recent studies show that the quality of response rate (complete cytogenetic response and major molecular response rate) is dependent on the residual plasma Imatinib. This study aims to evaluate the effectiveness of a strategy for dose adjustment of Imatinib Mesylate based on the measurement of the residual plasma imatinib in patients treated for at least 2 years Imatinib 400 mg / d in complete cytogenetic response for at least 1 year.
