Summary

This study looks at whether people with chronic myeloid leukemia (CML) can stop taking their daily targeted therapy (TKI) without the cancer coming back. It compares two approaches: stopping the drug suddenly after a year of normal dosing, versus slowly reducing the dose over a year before stopping. The goal is to see which method helps more patients stay in remission without needing medication, while also reducing side effects and improving quality of life.
