Trial Outcomes & Findings for Randomized Phase Lll Study of Imatinib Dose Optimization vs Nilotinib in CML Patients With Suboptimal Response to Imatinib (NCT NCT00802841)

NCT ID: NCT00802841

Last Updated: 2015-11-16

Results Overview

CCyR was assessed from bone marrow samples. CCyr was defined as having 0% Philadelphia positive (Ph+) chromosome metaphases in bone marrow.

Participant Flow

Participants were randomized in 1:1 ratio to imatinib 600 mg QD or nilotinib 400 mg BID for a 2 year study period.

Cross-over from one arm to the other was allowed for intolerant patients anytime during treatment, patients who failed to achieve CCyR after 6 months of treatment, loss of response, loss of CHR, loss of best achieved cytogenetic response any time during treatment, or other reason approved by the Study Management Committee.

Overall Survival (OS)
NA Months
The median OS time was not achieved because there were not enough number of events.
25.7 Months
The median was estimated, but the standard error could not be estimated due to the limitation of the Kaplan Meier method where there were too few events and the last participant had a death. Therefore, the 95% CI could not be calculated.
