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. It is also possible to generate antibodies that bind to receptors on the surface of can ....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. 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
Randomised Controlled Trial Of Virtual Reality Therapy After Stroke

Summary
Stroke is the second largest cause of disability in Australia. There is no cure, so patients must rely on therapy to restore movement. We want to make rehabilitation more effective. This study compares virtual reality game therapy (using the Nintendo Wii) to current best practice (constraint therapy). We anticipate patients will improve more with Wii therapy. Because it is fun, patients will enjoy therapy and spend longer training resulting in a greater recovery and better movement ability.
Optimal Duration Of Neoadjuvant Androgen Deprivation Therapy In Localised Prostate Cancer

Summary
Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer ....Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer of the prostate that has spread throughout the body for the last five decades, worldwide. It remains uncertain however whether AD administered before surgery or radiation will benefit any of the 8000 men each year who develop localised cancer by shrinking the cancer first. In 1996 a trial involving 800 men across Australia and New Zealand commenced under the auspices of the Trans-Tasman Radiation Oncology Group (TROG) to answer the questions: 1 - Does either 3 or 6 months AD prior to radiotherapy reduce the chances of recurrence of the cancer after radiotherapy? 2 - Does such therapy reduce the volume of tissue requiring radiotherapy and hence the chances of long term side effects after radiotherapy? This grant will support collection of follow-up information from the trial and hence answers to the questions asked.Read moreRead less
Danger Ideation Reduction Therapy For Obsessive-Compulsive Checkers: A Randomised Controlled Trial

Summary
Obsessive-compulsive disorder (OCD) is a psychiatric disorder that affects up to 3% of the general population. People with the disorder experience unpleasant intrusive thoughts that they find distressing and have a strong urge to perform particular behaviours. Fears about fire and burglary are common and excessive checking of electrical appliances and locks can take many hours a day. Checkers represent one of the largest OCD sub-groups.

People with the disorder experience unpleasant intrusive thoughts that they find distressing and have a strong urge to perform particular behaviours. Fears about fire and burglary are common and excessive checking of electrical appliances and locks can take many hours a day. Checkers represent one of the largest OCD sub-groups. Because of the time-consuming nature of the condition, social and occupational functioning is often severely restricted. Many sufferers will also experience extreme social isolation and depression. The World Health Organisation ranks this disorder as 20th among all causes of burden of disease. The development of effective interventions could substantially reduce the economic and social burden of this disabling anxiety disorder. The aim of this project is: (1) to compare the therapeutic efficacy of a new treatment approach (Danger Ideation Reduction Therapy) with that of Exposure and Response Prevention (ERP); It is hypothesised that: (1) subjects who receive 12 sessions of DIRT will show greater post-treatment and follow-up reductions in symptomatology than subjects who receive ERP.Read moreRead less

As a result treatment which reduces testosterone level ('androgen deprivation'[AD] therapy) can produce clinically important shrinkage of prostate cancer. Each year approximately 4000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Results from recent trials, including a large trial run in Australia and New Zealand by the Trans-Tasman Radiation Oncology Group (TROG) between 1996 and 2000, suggest that 6 months AD will benefit many of these men if administered in conjunction with radiotherapy.The aim of this project is to run a further trial to find out whether 12 months of AD, after radiotherapy will prevent the need for further treatment and prolong more lives than only 6 months AD. Bisphosphonate treatment also offers important benefits to prostate cancer patients because it can increase bony stregth by increasing its density and can also arrest cancerous growth in bones. A further aim of the trial therefore is to determine whether 18 months of bisphosphonate therapy (BP) will prevent bone loss (osteoporosis) caused by AD, and also further reduce the risk of secondary bone cancer developing. This trial will involve recruitment of 1000 men across Australia and New Zealand over a 5 year period. When complete the trial will determine whether further treatment can be delayed and life prolonged in up to half of all men in whom treatment presently fails. This grant will support collection of patient data and the necessary quality checks to ensure that reliable conclusions can be drawn.Read moreRead less
A Randomised Controlled Trial Of Alternative Treatments To Intramuscular Penicillin For Impetigo In Aboriginal Children

Summary
We will conduct clinical trials to find an effective, simple and cheap oral alternative to injected penicillin for skin sores which could become the universal standard of care whether the patient is in Melbourne or Milingimbi. It would also likely be adopted by the World Health Organization as a standard of care for developing countries. This would lead directly to a reduced burden of skin sores and their complications. It would also open the way for studies to explore even simpler regimens.
