So in December 2025 ELN published the updated MRD recommendations including some specific AML subtypes and also including new methodologies. So we now have FLT ITD MRD, studied by NGS, which can be used for MRD studies, in addition, for instance, to NPM1, since we have frequent positivity for both markers and for APL, the newer recommendation also, as in the past, confirmed that after 24 months we can stop follow-up in high-risk APL and while for lower risk for standard risk APL molecular follow-up is no longer recommended...
So in December 2025 ELN published the updated MRD recommendations including some specific AML subtypes and also including new methodologies. So we now have FLT ITD MRD, studied by NGS, which can be used for MRD studies, in addition, for instance, to NPM1, since we have frequent positivity for both markers and for APL, the newer recommendation also, as in the past, confirmed that after 24 months we can stop follow-up in high-risk APL and while for lower risk for standard risk APL molecular follow-up is no longer recommended. For NPM1 mutated AML and also for AML with CBF there is no major change in MRD studies, with the exception of low-level MRD, which is now considered as a new definition, for instance, for NPM1-mutated AML. And flow cytometry is confirmed as the preferred method for those patients who do not have a molecular marker.
