What was measured
The Kaplan-Meier curve was generated based on the first date of MMR until the date of the confirmed loss of MMR or censoring, objectively documented, for responders only. Confirmed loss of MMR was BCR-ABL/ABL IS ratio \>0.1% in association with a \>=5-fold increase in BCR-ABL/ABL IS ratio from the lowest value achieved up to that time-point confirmed by a second assessment at least 28 days later. Treatment discontinuation due to suboptimal response/treatment failure, progressive disease (PD) or death due to PD within 28 days of last dose were considered confirmed loss of MMR. PD was defined as disease progression to accelerated phase (AP) or blast phase (BP) CML.
Analysis population: mITT population included all randomized participants with Ph+ CML harboring the b2a2 and/or b3a2 transcript and baseline BCR-ABL copies \>0 with study drug assignment designated according to initial randomization and who achieved MMR (responders). Here, "Overall number of Participants Analyzed (N)" signifies number of participants evaluable for this outcome measure.
Groups in this outcome
Bosutinib
Participants with Philadelphia chromosome-positive CML received bosutinib tablets at a dose of 400 mg, orally once daily in the core treatment phase of 12 months and continued the same treatment into the extension phase or followed up for safety for up to approximately 4 years, until the end of the study, treatment failure, unacceptable toxicity, death, or withdrawal of consent, whichever occurred first.
Imatinib
Participants with Philadelphia chromosome-positive CML received imatinib tablets at a dose of 400 mg, orally once daily in the core treatment phase of 12 months and continued the same treatment into the extension phase or followed up for safety for up to approximately 4 years, until the end of the study, treatment failure, unacceptable toxicity, death, or withdrawal of consent, whichever occurred first.
