Summary
Recent research has focussed on molecular characterisation of high-risk acute leukaemia subtypes. This proposal will combine the power of genomic analysis, global analysis of protein kinases and stringent preclinical drug testing in order to improve the treatment of these high-risk acute leukaemia subtypes. Several innovative and interrelated projects within this Program will utilise a unique and clinically relevant experimental model to achieve their goals.
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.
A Preclinical Model Of Relapse In Acute Lymphoblastic Leukaemia

Funding Amount

Summary
Leukaemia is the most common type of cancer in children but resistance to therapy continues to be a significant problem. This project will investigate the biology of drug-resistance and relapse using a mouse model that replicates the human disease. We hope to identify novel therapeutic targets that can be used in combination with existing therapies to improve outcomes in this disease. We also hope to identify markers that can be used to screen for patients at increased risk of relapse.
AKR1C3 As A Potential Biomarker For Sensitivity Of T-lineage Acute Lymphoblastic Leukaemia To The Pre-prodrug PR-104

Summary
Multiagent chemotherapy is the most effective modality for the treatment of childhood ALL, the most common paediatric malignancy. Despite dramatic improvements in survival over the past 40 years, relapsed ALL remains one of the most common causes of death from disease in children. Therefore, innovative strategies are needed to benefit those children who respond poorly to established therapy. This application will test a novel therapy for a very aggressive subtype of childhood leukaemia.
A Phase I Study Of Autologous CD19 Specific Chimeric Antigen Receptor T-cells For Therapy Of Relapsed And Refractory B-cell Leukaemia And Lymphoma (The Auto-CAR19 Trial).

Summary
Most people with leukaemia and lymphoma who relapse early after chemotherapy die of their disease. Inserting special genes into immune cells can enable them to kill leukaemia and lymphoma and has led to dramatic cures, but the cost of the viral vectors used to make these cells is prohibitively expensive. We will make leukaemia and lymphoma specific immune cells from patients using an inexpensive non-viral system, then administer the immune cells to patients to assess their safety and efficacy.
Circulating Tumour DNA To Monitor Treatment Response And Resistance In Chronic Lymphocytic Leukaemia

Funding Amount
$876,950.00
Summary
Many cancers shed small amounts of DNA (ctDNA) into the patient’s bloodstream and recent advances in genomic technologies now allow levels of ctDNA to be accurately measured in the blood. Changes in ctDNA levels have potential to be used as specific markers of disease progression and/or response to cancer therapy. This project will evaluate if ctDNA can be used to monitor treatment responses and individualise treatment decisions in patients with chronic lymphocytic leukaemia.
A Phase I Study Of PiggyBac CD19 Specific Chimeric Antigen Receptor T-cells For Therapy Of Persistent And Relapsed B-cell Leukaemia And Lymphoma Post Allogeneic Stem Cell Transplantation (The CARTELL Study).

Summary
Most people with relapsed leukaemia and lymphoma after bone marrow transplant die of their disease. Inserting special genes into immune cells can enable them to kill leukaemia and lymphoma and has led to dramatic cures, but there is little experience in bone marrow transplant patients. We will make leukaemia and lymphoma specific immune cells from normal bone marrow transplant donors, then administer the immune cells to transplant patients to assess their safety and effectiveness.
I am a cancer cell biologist investigating molecular mechanisms of leukaemia cell resistance to chemotherapeutic drugs, and novel strategies for the management of high risk or relapsed disease. For these purposes I have developed orthotopic xenograft mode
Glucocorticoid Resistance In Paediatric Acute Lymphoblastic Leukaemia

Funding Amount
$394,721.00
Summary
Glucocorticoids are among the most effective drugs used in the treatment of many haematological malignancies, including leukaemia, lymphoma and multiple myeloma. However, the development of tumour cell resistance to these drugs remains a significant problem, and clinically relevant mechanisms of glucocorticoid resistance remain poorly understood. This project aims to define mechanisms of resistance to glucocorticoids and develop new drugs to reverse resistance.
Redirecting T-cells For Immunotherapy Of Leukaemia And Lymphoma By The Expression Of A CD19-specific Chimeric Antigen Receptor Using The PiggyBac Transposon Gene Modification System

Summary
Most lymphomas respond to therapy but then relapse. Immune cells can attack and kill virus related lymphomas. However, most lymphomas are NOT virus related. We will create immune cells targeting these virus negative lymphomas by inserting artificial receptors into the immune cells. These receptors attach to the lymphoma and activate the immune cells. The immune cells will home to the lymphoma, kill lymphoma cells and persist in the body for many years, preventing lymphoma relapse.
