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.
Fear Relapse: Neural Substrates Underlying Its Inhibition And Prevention

Summary
Exposure-based therapies are effective for anxiety disorders such as post traumatic stress, but two challenges remain: 1) patients that have learned to inhibit their fear are likely to relapse, requiring further therapy; 2) many drop out of therapy since it is aversive and anxiety provoking. We use an animal model to: 1) identify the neural substrates underlying fear inhibition; and 2) determine the conditions that prevent relapse and encourage participation in treatment.
An RCT Of Cannabinoid Replacement Therapy (Sativex®) For The Management Of Treatment-resistant Cannabis Dependent Patients

Summary
This project is the first-ever outpatient RCT to test if the pharmaceutical cannabinoid Sativex can safely and cost-effectively deliver better treatment outcomes for patients seeking treatment for chronic cannabis dependence. Sativex is a mouth spray with equal parts THC and cannabidiol, and appears to have a safer pharmacological profile than illicit cannabis or synthetic THC alone. Thus Sativex may lead to lower rates of psychiatric adverse events and increased cannabis abstinence rates.
Targeting Tumour-Stromal Interactions In Pancreatic Cancer

Summary
Pancreatic cancer claims five Australian lives every day and is one of the nations most lethal diseases. Despite aggressive treatment regimes, there has been no improvement in patient survival in the last decade. Evidence suggests that targeting cancer cells alone is not enough. The intense stromal reaction inhibits drug delivery and increases the aggressiveness of the tumours. Thus, depletion of the stroma or pancreatic stellate cells is a potential therapeutic target.
Targeting Drug-Resistance In Paediatric Acute Lymphoblastic Leukaemia

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, particularly for patients that develop drug-resistance such as those at the time of relapse.
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.

It has long been known that testosterone removal impedes prostate cancer growth, although not permanently. The removal of testosterone, however, has side effects , including loss of libido, hot flushes, weight gain, and in the longer term osteoporosis, loss of muscle bulk and mental changes such as loss of memory. Any benefit to be gained for a patient must therefore be weighed against these side effects. This is particularly relevant in situations in which cure is not possible, when the aim of treatment should be to manage symptoms (either by preventing or delaying them or treating them as they arise). There are two situations in which a man may be diagnosed as having active prostate cancer but be without symptoms requiring immediate treatment. The first is after the failure of curative treatment, shown by the presence of prostate specific antigen (PSA) in the blood, but without any other evidence of prostate cancer. The second is a man newly diagnosed with asymptomatic prostate cancer, but with other reasons (such as heart disease) which make an attempt at cure inappropriate. We do not know in either case whether or not men live longer if treatment is started immediately, or whether it is reasonable to wait until symptoms develop, thus potentially postponing the side effects of treatment. The trial will therefore include these two groups of men. Half the men will be randomised to receive immediate treatment, and half to treatment starting when symptoms develop, or when there is evidence of progressive disease. The main endpoint is overall survival, balanced against quality of life and side effects from the disease and treatment. The hypothesis is that early treatment will improve survival with acceptable effects on quality of life.Read moreRead less

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.
How Do Bone-active Drugs Increase Patient Survival?

Summary
Bisphosphonates are a class of drugs used to prevent bone destruction in diseases such as osteoporosis. Evidence is emerging that these drugs also act on cells outside the skeleton to have additional beneficial effects, for example prolonging patient survival. This project will identify the cells affected and the mechanisms involved. With this knowledge, these drugs could be used more effectively and in different ways for the prevention or treatment of cancer and chronic human illnesses.
Bone Marrow Macrophages: “Resident Evil” In The Establishment And Progression Of Multiple Myeloma

Summary
Multiple myeloma (MM) is a cancer that develops within the bone marrow (BM). To date, which cells of the BM stroma are required for the support of MM growth remains unknown. Our preliminary data suggest BM resident macrophages, expressing CD169 and CX3CR1, are essential for MM growth. Using innovative and elegant animal models of MM, we will define the role of these macrophages in MM growth and determine if macrophage-targeted therapies can delay MM growth in the relapsed disease setting.
