| Measure | Time frame |
|---|---|
| CMR rate at 1 year after discontinuation of nilotinib treatment in patients who have sustained CMR for 2 years after initiation of the study. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) CMR rate at 2 and 3 years after discontinuation of nilotinib treatment in patients who have sustained CMR for 2 years after initiation of the study. Recurrence-free survival (RFS), event-free survival (EFS), progression-free survival (PFS), and overall survival (OS) at 1, 2, and 3 years after the discontinuation of nilotinib. 2) Rate of patients who have sustained CMR for 2 years at 24 months after initiation of the study. 3) Correlation between the time to CMR/MMR and the CMR rate at 1, 2, and 3 years after the discontinuation of treatment. 4) Correlation between the CMR duration prior to the discontinuation of nilotinib treatment and the CMR rate at 1, 2, and 3 years after discontinuation. 5) Exploration of predictors of CMR sustenance during nilotinib treatment. | — |
