Real world outcomes of asciminib in relapsed/refractory Philadelphia chromosome positive B-ALL and blast Phase CML (ASH 2025)
"While its efficacy is wellestablished in chronic-phase CML, the real-world data on its use in relapsed/refractory (r/r) B-ALL andblast-phase CML (CML-BP), particularly among patients who are ponatinib-refractory or those withcomplex resistance mutations remains underexplored.MethodsWe performed a retrospective analysis of adult patients with either B-ALL or CML-BP who receivedasciminib at our institution between November 1, 2021, and March 30, 2025. While higher dosing may be effectivein overcoming specific mutations, it could also contribute to the emergence of additional resistancemutations. These findings underscore the need for prospective studies to optimize dosing strategies,sequencing, and resistance monitoring."
