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 inhibitor of ABL/BCR-ABL1 tyrosine kinase for the treatment of patients with Philadelphia chromosome-positive CML, including those with the T315I mutation.
In most patients with chronic myeloid leukemia (CML), progression of the disease is driven primarily by a translocation of the Philadelphia chromosome that creates an oncogenic fusion gene, BCR-ABL1, between the BCR and ABL1 genes. This fusion gene produces a resultant fusion protein, BCR-ABL1, which exhibits elevated tyrosine kinase and transforming activities that contribute to CML proliferation. 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 is indicated for the treatment of adult patients with Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML) in chronic phase who have been previously treated with ≥2 tyrosine kinase inhibitors. It is also indicated in the treatment of Ph+ CML in adult patients with the T315I mutation.
