Summary
Killer T lymphocytes can penetrate tumors and their transfer into cancer patients has demonstrated some encouraging results, but this form of immunotherapy remain ineffective in most cancer patients. We propose to improve the tumor trafficking and anti-tumor activities of killer cells by genetically engineering them with proteins that will enable them to recognise and destroy cancer cells. The outcomes of this project will validate this novel approach for treatment of cancer patients.

Summary
Antibodies are a major component of the bodies immune system that bind (i.e. stick) to foreign substances such as viruses. Once bound, these antibodies can activate other parts of the immune system, which help destroy the foreign substance. Analogous to the situation above, a number of institutions are testing antibodies that bind to cancer cells, in order to determine if they are able to destroy these cells.

Once bound, these antibodies can activate other parts of the immune system, which help destroy the foreign substance. Analogous to the situation above, a number of institutions are testing antibodies that bind to cancer cells, in order to determine if they are able to destroy these cells. It is also possible to generate antibodies that bind to receptors on the surface of cancer cells and block their function. If you target a receptor critical to the growth or survival of a cancer cell in this way, then swtiching-off this signal may inhibit tumor growth. In this proposal we plan to test a panel antibodies that recognize receptors important to the growth of brain cancer. Two of these antibodies have been generated and the other two will be made as part of this proposal. A key aspect of this proposal will be testing these antibodies in combination to determine how many receptors need to be targeted in order to get complete tumor regressions in animal models. Overall this work will help us identify new therapeutic strategies for the treatment of brain cancer. Finally, we will also analyze the way different receptors interact together in brain cancer cells.Read moreRead less
A Randomised Placebo-controlled Trial Of Antibiotics To Prevent Urinary Tract Infection In Children

Summary
This study is needed to determine whether a common clinical practice long-term antibiotic treatment for children following urinary tract infection (UTI) - is safe and effective in preventing further UTI and if so, whether all appropriate children are being treated. UTI will affect about 10% of Australian children by high school age (88,000 children per year). Because UTI may damage the kidneys, the management priority for children with UTI has been prevention of further infection. Currently this ....This study is needed to determine whether a common clinical practice long-term antibiotic treatment for children following urinary tract infection (UTI) - is safe and effective in preventing further UTI and if so, whether all appropriate children are being treated. UTI will affect about 10% of Australian children by high school age (88,000 children per year). Because UTI may damage the kidneys, the management priority for children with UTI has been prevention of further infection. Currently this means the identification of children thought to be most at risk of recurrent UTI by renal tract imaging. Those found to have reflux of urine from the bladder to the kidney (present in about 30% of those with UTI) are then placed on antibiotics fro 2-5 years. Unfortunately there has never been a properly designed trial to test whether antibiotics do really prevent UTI and if so, whether children with reflux are the appropriate and only group requiring treatment. Long term antibiotics may in fact do more harm than good because of side effects like skin, bowel and blood problems and because resistant bacteria may develop. The design of this study involves the random allocation of placebo or antibiotic (cotrimoxazole, the usual antibiotic given in this case) to about 800 children after their first symptomatic UTI. These children are treated and followed for one year to determine the rate of futher UTI in both groups. Any difference in outcome between the two groups of children will be because of the antibiotic treatment. This study may prove long-term antibiotics are ineffective and therefore should not be routinely used. In this case investigation of children to detect vesicoureteric reflux would serve little purpose and should be abandoned. Alternatively antibiotic treatment may be shown as effective treatment for preventing further UTI and in this case the study will clearly identify those children who will benefit.Read moreRead less

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.

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

Summary
BreastScreen Australia uses interim measures such as participation, small cancer detection and interval cancer rates to monitor the impact of the program on mortality. Using BreastScreen Victoria as a case study, we will estimate the direct impact of the program on mortality for screened women, addressing Cancer Australia's priority of 'Improving screening program outcomes to ensure that patients can be identified and treated appropriately and ensuring that screening services are effective'.
Development Of Antimicrobial Peptides Targeting Oral Pathogenic Bacteria

Summary
The bacterial associated oral diseases; periodontitis and caries are major public health problems. The prevalence of these diseases and increasing bacterial antibiotic resistance has meant there is a need to develop new therapies. This project addresses this by modifying a novel class of antibiotics/antiseptics �antimicrobial peptides� to target oral bacteria and testing them using a newly developed screening method. This project will lead to new therapies for periodontitis and caries.
