Translational Research Program To Advance Clinical Outcomes In Acute Myeloid Leukaemia

Funding Amount

Summary
Five-year survival in acute myeloid leukaemia (AML) is only 27%, placing it amongst the worst-ranked cancers for clinical outcome. Improved patient outcomes will be achieved through implementation of a Translational Research Program to support novel agent drug testing, early-phase and randomised clinical trials and a national clinical registry to audit outcomes. New insights into leukaemic stem cell function and mechanisms of drug resistance will inform the design of future clinical trials.
A New Model Of T Cell Lymphoma Induced By An Ets Transcription Factor

Summary
The identification of leukaemia-causing genes is crucial as once these are found new specific drugs can be developed. This is best exemplified by the new drug, Gleevec, that inhibits a leukaemia-causing gene in myeloid leukaemia. This has allowed a large reduction of high chemotherapy treatment but has induced remission in around 80% of patients. This proposal has identified a novel leukaemia-causing gene for T cell leukaemia. Therefore, new specific drugs can now be made to inhibit it.
New Compounds For Tailored Therapy Against MLL-rearranged Leukaemia

Funding Amount
$326,401.00
Summary
Some of the worst leukaemia survival rates are found in children and adults whose leukaemias display abnormalities of the MLL gene and alternative therapies are therefore urgently required for these patients. The aim of this project is to develop new compounds that specifically inhibit this abnormal gene and in turn inhibit the growth of these cells in the patient. In this way we hope to provide new and more effective therapies for patients affected with this aggressive type of leukaemia.
The Biology And Clinical Manifestations Of Chronic Myeloid Leukaemia

Summary
I am a haematologist studying the biology and clinical manifestations of chronic myeloid leukaemia with particular reference to the dynamics of response to kinase inhibitor therapy and the causes and clinical management of suboptimal response and drug res
Mechanisms Of Glucocorticoid Resistance In Acute Lymphoblastic Leukaemia

Funding Amount

Summary
Glucocorticoids are extremely active drugs used in the treatment of childhood acute lymphoblastic leukaemia (ALL), yet a proportion of patients respond poorly to therapy and exhibit resistance at relapse. Clinically relevant mechanisms of glucocorticoid resistance are poorly understood, principally due to lack of appropriate experimental models. This project will reveal novel mechanisms of drug resistance in childhood leukaemia and lead to novel therapeutic strategies to improve outcome.
Overcoming The Differentiation Block In Acute Myeloid Leukaemia

Funding Amount
$811,669.00
Summary
Acute myeloid leukaemia (AML) is an aggressive leukaemia with poor overall survival. About 50% of AML cases have genetic mutations that disable PU.1, which in turn alters the expression of many other genes that cause leukaemia. We have developed new AML models allowing reversible inhibition of PU.1, and have shown that re-engaging PU.1 function causes AML regression. This project aims to understand PU.1 functions in AML and identify rational drug targets for treatment-resistant disease.
Molecular Pathways Mediating Quiescence And Resistance In Leukaemia Stem Cells In Acute Myeloid Leukaemia.

Funding Amount
$100,381.00
Summary
Acute myeloid leukaemia (AML) is a devastating cancer of the blood and bone marrow which is rapidly fatal unless effectively treated with chemotherapy. AML is caused by genetic events that alter normal blood stem cells to give them a growth and survival advantage and also may confer resistance to chemotherapy in some cases. We will evaluate and target the mechanism of this resistance in laboratory models. This information can then be used to design new treatments to improve outcomes in AML.
Roles Of The EMT Transcription Factors In Epigenetic Remodelling And Myeloid Cell Transformation.

Funding Amount
$809,520.00
Summary
This project is based upon our novel discoveries that identified ZEB2 and SNAI1 as novel genes involved in the development of aggressive forms of blood cancer. During the course of this proposal we will find new drug targets and new drug treatment options using existing drugs that will specifically target cancer initiating cells in order to kill aggressive forms of blood cancers that are currently refractory to treatment.
Development And Assessment Of Novel Assays To Predict Response To Second-line TKI Therapy In Imatinib-resistant CML

Funding Amount
$491,308.00
Summary
Patients with chronic myeloid leukaemia (CML) respond well to imatinib, the first small molecule developed to block the kinase activity of the causative oncogene in CML, BCR-ABL. However some patients develop resistance. Several new kinase inhibitors are now available that are effective in some patients with imatinib resistance. We plan to develop biological and molecular assays to predict if a CML patient will respond to a specific second-line kinase inhibitor to optimise second-line therapy.
GADD45A Promoter Methylation And Poor Prognosis In AML:mechanism And Clinical Significance

Funding Amount
$706,280.00
Summary
DNA methylation associated with the GADD45A gene defines an AML patient group with poor overall survival and limited treatment options. We will investigate the significance of this modification for the response of AML cells to chemotherapy and dissect the mechanism associated with this event. To translate these findings into the clinic we will test whether these patients are responsive to new agents targeting DNA methylation, and investigate survival of patients in a large independent cohort
