Efficacy of a combination of TKI and a novel allosteric inhibitor asciminib in chronic myeloid leukaemia

Tim Hughes honours - asciminib

Clinical trials for the treatment of Chronic Myeloid Leukemia (CML) are currently underway using asciminib (ABL001).

The trials are using this allosteric inhibitor alone, and in combination with ATP-competitive tyrosine kinase inhibitors (TKIs: imatinib, nilotinib or dasatinib), to inhibit the constitutively active tyrosine kinase Bcr-Abl.

We will then examine mechanisms of treatment resistance in vitro, in an attempt to predict emergent disease resistance mechanisms that may arise.

The aims of this project are: 

  1. Investigation of the synergistic effect of the combination of TKI and asciminib. 
  2. Understand the signalling pathway changes in BCR-ABL+ cell lines and CML patient cells when combination therapy is given.
  3. Generation of resistant cell lines in the laboratory setting. This provides a useful tool for predicting and studying patient responses in vivo. 

Understanding how these drugs work in synergy will enhance our ability to predict whether patients are likely to respond to combination therapy, and clarify ways to maximise synergism between these agents.

In this project, BCR-ABL1+ cell lines will be exposed long term to gradually increasing concentrations of asciminib in combination with TKI. Mechanisms of resistance will be interrogated during resistance development and once overt resistance is observed.
