Summary
Radiotherapy for prostate cancer treatment will be more effective when we have better knowledge of what patient anatomy needs to be targeted, and what needs to be avoided. This project will combine data collected during a large Australasian prostate cancer radiotherapy trial, ‘RADAR’, with data collected using new patient imaging methods to determine how patient anatomy impacts on the effectiveness of their treatment and the side-effects they experience.

Summary
Women in malaria-endemic areas such as coastal PNG are at high risk of malaria in pregnancy. To prevent the substantially increased malaria-associated morbidity and mortality in mother and child, and because even asymptomatic infections can be deleterious, there has been a move to giving antimalarial drugs regularly during pregnancy regardless of the mother's clinical or parasitological status. In poor tropical countries, such treatment usually comprises safe and inexpensive agents such as chlor ....Women in malaria-endemic areas such as coastal PNG are at high risk of malaria in pregnancy. To prevent the substantially increased malaria-associated morbidity and mortality in mother and child, and because even asymptomatic infections can be deleterious, there has been a move to giving antimalarial drugs regularly during pregnancy regardless of the mother's clinical or parasitological status. In poor tropical countries, such treatment usually comprises safe and inexpensive agents such as chloroquine and Fansidar. There are two main issues with this approach. First, the efficacy of such conventional agents is waning and this increases the risk of break-through malaria. Second, there are few data on how the drugs are handled in pregnancy on which to base recommendations for treatment. We plan to collect information on the disposition and effectiveness of chloroquine and Fansidar in women with malaria in pregnancy in PNG that should allow a critical appraisal of the usefulness of current regimens in PNG and in other tropical countries where parasite resistance to these agents is emerging. Artemisinin combination therapy (ACT) in the form of a novel artemisinin drug and a longer-acting partner has been suggested as the most promising alternative therapy for malaria in pregnancy if conventional drugs fail. We plan to assess the safety of a leading ACT formulation, namely dihydroartemisinin and the chloroquine-like drug piperaquine (DHA-PQ), in animals before extending our studies to women with malaria in PNG. These latter studies will allow an evaluation of the safety and efficacy of DHA-PQ as novel therapy for malaria in pregnancy in PNG and other tropical countries.Read moreRead less
Unravelling The Mechanism Of MHC Class-I Associated Drug Hypersensitivities

Summary
Some drugs cause adverse reactions that are life threatening. We think these reactions are mediated by killer T cells as they are genetically controlled by immune response genes that normally guide immunity to microbes. We will study immune reactions to the drug abacavir, used to treat HIV (AIDS); allopurinol used to prevent gout and carbamazepine, used to treat epilepsy. The study may also help devise better treatments for patients who experience severe forms of these reactions.
Multidrug Resistance Protein 1 Inhibitors To Sensitise Cancers To Chemotherapy

Summary
Multidrug resistance protein 1 (MRP1) is often present at high levels in cancer cells, where it pumps chemotherapy drugs back out, causing drug resistance. Inhibitors that block MRP1 would increase the effectiveness of chemotherapy. We have developed MRP1 inhibitors with promising activity in cancer cells and mouse tumours and will now develop these inhibitors for clinical application and commercialisation.

Summary
Histone deacetylase inhibitors (HDACi) are a novel class of anti-tumor agents, recently approved for the treatment of cutaneous T-cell lymphoma. The goal of this study is to improve our understanding of how this class of drug induces tumor cell death. These studies are designed to provide insight into which patients are most likely to benefit from treatment with these agents.

A Phase III Trial Comparing Adjuvant Versus Salvage Radiotherapy For High Risk Patients Post Radical Prostatectomy

Funding Amount
$819,138.00
Summary
About half of all patients Treated with an operation to remove their prostate cancer have a high chance of the cancer coming back. Giving immediate radiotherapy to all patients will improve cure rates but does not benefit all men and can cause significant side effects. This study explores whether it is safe to wait and only give radiotherapy when there is a rising PSA after surgery indicating active cancer. A total of 470 men from Australasia will enter this study comparing the two approaches.
Interplay Between Metabolic Reprogramming And Oncogenic Signalling In The Cellular Response To Chemotherapy

Summary
Chemotherapy resistance is a major barrier to the treatment of triple-negative breast cancer (TNBC). We seek to uncover an intimate link between cell metabolism and oncogenic signalling pathways in regulating the cellular response to chemotherapy. Our studies will identify a critical mechanism limiting the therapeutic efficacy of chemotherapy and investigate combination therapy strategies that could improve the treatment of TNBC.
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.

The aim of the study is to reduce the burden and distress associated with cancer chemotherapy. Cancer chemotherapy is associated with physical (nausea, fatigue, hair loss, infection) and psychosocial (fear, anxiety, worry about family) effects that cause significant distress. Patients experience a highly level of pre-treatment anxiety and for many this distress lasts across the course of treatment. Over the past decade there has been a dramatic shift in chemotherapy delivery to the outpatient setting. This means that patients are now responsibile for monitoring their own health at home and may need to use self-care strategies to deal with the many adverse effects of treatment. Pre-treatment education has usually focused on providing information about the facts of treatment, i.e. likelihood of nausea, rather than preparing the patient for the experience of treatment or helping them to manage the self-care demands associated with receiving treatment in the outpatient setting. The innovative education program tested here is the first of its type to draw on high level research evidence about preparing patients for potentially threatening medical procedures, tailoring this education to the individual situation of the patient and coaching the patient to implement evidence-based self-care behaviours and to use stress reduction techniques across the course of treatment.Read moreRead less
