Leukemia drug breakthrough: study tests tapering strategy to free patients from daily pills
NCT ID NCT05753384
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
