Summary
Brief summary
We conducted a trial in 103 de-novo chronic phase CML patients using imatinib 600 mg/day initially, increasing to 800 mg for suboptimal response. Ten patients not achieving major cytogenetic response (MCR) at 6 months and 13 with no complete cytogenetic response (CCR) at 9 months were eligible for dose increase, but this was only possible in 7/23 patients due mainly to non-hematologic toxicities. CCR was achieved in 90% and 95% of patients by 12 and 24 months, compared to rates of 69% and 80% in the IRIS trial. Major molecular response (MMR) was achieved in 47% and 72% of patients by 12 and 24 months compared to estimated frequencies of 40% and 55% in the IRIS trial. In the group averaging 600 mg throughout the first 12 months (n=51) 89% achieved MMR by 24 months compared to 50% in those averaging 500-599 mg in the first 6 months and 600mg in the second (n=18) (p=0.009). The superior molecular responses achieved in imatinib-treated patients who averaged 600 mg/day, compared to patients who were dose modified, suggest that early dose intensity of imatinib therapy may be critical to optimise response in CML.
