Pathway Description
Asciminib Inhibition of BCR-ABL
Homo sapiens
Drug Action Pathway
Asciminib is an inhibitor of ABL/BCR-ABL1 tyrosine kinase for the treatment of patients with Philadelphia chromosome-positive CML, including those with the T315I mutation. Asciminib is an allosteric inhibitor of the BCR-ABL1 tyrosine kinase. It binds to the myristoyl pocket of the ABL1 portion of the fusion protein and locks it into an inactive conformation, preventing its oncogenic activity.
Asciminib exerts its therapeutic activity by inhibiting an oncogenic protein responsible for the proliferation of CML. It may be administered orally once or twice a day depending on the condition being treated. By increasing the total daily dose 5-fold as compared to standard therapy (80mg daily vs. 400mg daily), it can be used to treat Ph+ CML with the T315I mutation, a typically treatment-resistant variant of the disease.
