Treatment goals are focused on getting CML under control1 while preserving/improving QOL2
Getting CML under control
Potential to attempt TFR2
Improve survival2
Achieve and maintain milestones1
Prevent disease progression1
Preserving/Improving QOL
Improve or maintain QOL2
Minimize treatment-related toxicities3
- Specific treatment goals are related to individual patient factors, and they may vary or evolve over time and by line of therapy4
- Achievement of milestones (hematologic, cytogenetic, and molecular)5 may be linked to outcomes, including reduced progression1 and prolonged survival2
Goals in newly diagnosed or patients with fewer treatments
- TFR2 and rapid and durable achievement of milestones (EMR, DMR, MMR)1
Goals in older patients or with multiple treatments
- Maintaining QOL with less-aggressive milestone goals6
Deeper molecular responses are associated with improved outcomes7
- Getting CML under control
MMR (0.1% BCR::ABL1IS) as a predictor of PFS and OS1
QOL, Quality of life; CML, Chronic myeloid leukemia; TFR, treatment-free remission; EMR, Early molecular response; DMR, Deep molecular response; ABL1, Abelson protein tyrosine kinase 1; BCR, breakpoint cluster region; CCyR, complete cytogenetic response; CHR, complete hematologic response; IS, International Scale; MMR, major molecular response (BCR::ABL1IS 0.1%); MR4, BCR::ABL1IS 0.01%; MR4·5, BCR::ABL1IS 0.0032%; OS, overall survival; PFS, progression-free survival; TFR, treatment-free remission. a BCR::ABL1IS 10% is roughly equivalent to CHR. b BCR::ABL1IS <1% is roughly equivalent to CCyR.
