- Percentage of Patients Achieving Major Molecular Response (MMR) After 12 Months of CML Treatment [ Time Frame: At 12 months after Day 1 initiation of 1st line treatment with imatinib or imatinib at any dose, after less than optimal response to first-line imatinib. ]
Major Molecular Response, is defined as a 3-log reduction in BCR-ABL transcripts from the standardized baseline, which represents 100% on the international scale, so a 3-log reduction is fixed at 0.1% for MMR; N/A = not applicable. 95% CI is Clopper-Pearson(Exact) two-sided 95% confidence intervals.
P-value is based on Cochran-Mantel-Haenszel (CMH) test stratified by Sokal score(high, intermediate, low, and unknown) and time between 3 month molecular analysis and randomization (<=4 weeks vs >4 weeks). Month 12 is calculated fro
- Median Time to Major Molecular Response (MMR) [ Time Frame: Up to 10 years ]Time to MMR is how fast patients achieve optimal response. It is the time between randomization date and first date that MMR criteria are satisfied.
- Time to Molecular Response (MR)^4.5 [ Time Frame: Up to 10 years ]Time to MR^4.5 is how fast patients achieve a deeper response. It is the time between randomization date and first date that MR^4.5 criteria are satisfied.
- Progression Free Survival (PFS) [ Time Frame: Up to 10 years ]PFS is how long patients are likely to live without progression of their disease. It is the time from randomization date to progression date or death date, whichever occurs first.
- Overall Survival (OS) [ Time Frame: Up to 10 years ]OS is how long patients are likely to remain alive. It is the time from randomization date to death date.
