Research Program Overview

Chronic myeloid leukaemia (CML) is fatal if untreated. Due to significant advances in drug therapy, patients now sustain long term survival. However, 20-30% of patients fail therapy. Newer, more potent drugs are continually being developed to treat or limit drug resistance. However, these drugs are associated with higher cardiovascular toxicity and have not shown a survival advantage. It is currently not possible to identify patients at the time of diagnosis who are destined to fail therapy. Therefore, it is not possible to determine which patients could benefit from more potent drugs despite the increased risk.

Our research is focussed on the development and clinical evaluation of novel molecular approaches to understand and predict drug resistance for patients with CML. The pace of discovery of resistance mechanisms is now substantially more rapid due to new technology. We can now simultaneously examine hundreds to thousands of genes to find the causes of drug resistance and to identify new drug targets. Working with pharmaceutical companies and monitoring patients enrolled in international clinical trials we aim to discover the molecular factors associated with treatment failure. Our objective is to translate our work into clinical practice to improve risk stratification and enhance therapy decisions for better outcomes for patients with CML.

Current Research Projects

  • Defining high risk mutations at diagnosis of CML and at treatment failure.
  • Develop enhanced bioinformatic tools and machine learning for improved risk stratification in CML.
  • Examine the association between clonal haematopoiesis and late relapse for patients with treatment-free remission.
  • Examine complex structural rearrangement of the Philadelphia chromosome to determine if chromoplexy constitutes a new mechanism contributing to drug resistance.
