Notas
T315I emergence on imatinib / 2nd-gen TKI mandates switch to ponatinib (full-dose 45 mg → response-adjusted to 15 mg per OPTIC) or asciminib STAMP (response rates ~50% in T315I-positive). Both NOT registered in Ukraine — major access barrier. AlloHCT remains alternative for fit patients without ponatinib/asciminib access. Mandatory kinase-domain resistance mutation screening at TKI failure or suboptimal response per ELN 2020 milestones. STUB — requires clinical co-lead signoff.
