ABL1 and chronic myelogenous leukemia, BCR-ABL1 positive: Asciminib (ABL001), a FDA-approved fourth-generation TKI, is shown to be efficient against BCR-ABL1-dependent and independent mutations such as T315I with a moderate toxicity potential by blocking binding to the BCR-ABL1 myristoyl pocket (STAMP) and producing therapeutic synergism in lowering CRK-like protein phosphorylation for CML stem cells either as monotherapy or in combination with other TKIs [171, 172].
