E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Goal of the study is to investigate whether in patients with CML in chronic phase and confirmed MMR without MR4.5 receiving Imatinib at 400 to 800 mg daily a switch to Nilotinib at 300 mg twice daily results in a higher proportion of patients with con-firmed MR4 after two years of study treatment when compared with patients who continue receiving Imatinib (400 to 800 mg daily). |
|
E.2.2 | Secondary objectives of the trial |
To determine -the cumulative incidence of MR4 and MR4.5 after one and two years of study treatment -and the proportion of patients with MR4 and MR4.5 lasting for at least two years -and the kinetics of BCR-ABL transcript levels over time -and the proportion of patients with confirmed MR4 two years after cross-over from Imatinib to Nilotinib in patients failing the primary endpoint in the Imatinib arm -and whether baseline clinical data are informative with respect to achievement of confirmed MR4 -and changes in the health-related Quality of Life
-To investigate the predictive value of a previously developed mathematical model of CML treatment with respect to the patient-specific probability of reaching confirmed MR4 under continuous Imatinib -To collect data to establish a mathematical model regarding the prediction accuracy of the molecular relapse probability after treatment discontinuation (to be validated in DECLINEplus) -Study drug compliance |
