Summary
Fibrosis is a serious biological process that occurs in many disease conditions, including cancer, inflammation and infections. We have produced antibodies to CXCR7, and these antibodies completely inhibit fibrosis in a mouse model. We plan to develop these antibodies in to a suitable drug for human clinical trials.
There is an unmet need for safe and effective anti-inflammatory drugs. Because P38 MAPK intracellular signalling modulates multiple pro-inflammatory cytokine actions, it appears to be an ideal candidate pathway. P38 inhibitors have been limited by their toxicity within hepatocytes. The aim of this program therefore is to develop agents with enhanced P38 MAPK inhibitory effects as well as reduced liver toxicity based on known structure activity relationships.
Commercialisation Of A Glycoprofiling Diagnostic Kit And Novel Therapies For Biofilm Related Respiratory Disorders

Summary
Our preliminary studies have shown that a group of patients who suffer from chronic inflammatory disease and have bacterial biofilm identified on their mucosa have worse outcomes even after surgery. We have shown that they lack certain small protein and sugar molecules on their respiratory lining. We aim to use this technology as a diagnostic tool to aid the doctor in prescribing the appropriate treatment for these patients to prevent bacteria regrowing in their respiratory tract.
Development Of A Novel Orally Active Peptide For The Treatment Of Pain

Summary
Chronic pain from damage to the nervous system is difficult to treat. A new type of drug has recently been developed from sea snail venom to treat chronic pain but is given by injection, which limits its use. Our research has developed a stable molecule that has analgesic activity when ingested. This proposal focuses on further testing to fully establish this molecule's therapeutic potential. This information can then attract a commercial partner to bring the new drug into general use.

Pre-clinical Evaluation Of Nano-membrane Dressings To Promote Wound Healing

Summary
This project will investigate whether a novel type of wound dressing can promote faster wound healing and reduce scarring. Time taken to heal is one of the best predictors of whether a wound will heal with significant scarring. The faster wounds heal the better. We have identified a new dressing with specific nano-scale pores that may promote faster healing. This dressing will be tested in the best model of human wound healing with the potential to progress to clinical trials if successful.

Summary
The aim of this project is to assist in the development of a novel device to treat poor delivery of blood to the kidneys in conditions such as heart muscle weakness (chronic heart failure, CHF). Specifically we aim to build a prototype and test the device in a relevant animal model of CHF. Chronic heart failure is a major public health problem affecting >10% of the adult population over the age of 60 years.

Specifically we aim to build a prototype and test the device in a relevant animal model of CHF. Chronic heart failure is a major public health problem affecting >10% of the adult population over the age of 60 years. It is associated with high morbidity, mortality, frequent hospitalisation and major cost burden on the public health system. Weak heart muscle results in poor delivery of blood to the kidneys. Poor delivery to the kidneys activates circulating hormones which in turn further impair cardiac function by adverse effects on the heart. We have developed and patented a novel catheter based system for improvement of renal function via a purpose built device. Proof-of-concept studies have shown that the device should improve kidney blood flow in the setting of CHF. Given the huge public health problem of heart failure and the importance of the kidney in this setting, the commercial potential for a simple device that can be positioned via a catheter-based approach, permanently implanted is large. The device is currently being constructed by the Monash University Department of Engineering where expertise exists with regard to biomedical devices and materials engineering. A series of proof-of-concept studies will then be performed in sheep, as the vasculature of the sheep roughly approximates the dimensions of man. Sheep with CHF will have the device inserted percutaneously into the aorta. Measurements will be made of renal artery flow, relevant circulatory hormones and ultrasound of the heart at baseline (pre-deployment) and following deployment. We believe the above studies (should they be successful) will be sufficient to constitute definitive proof-of-concept and thus allow the device to be commercialised, most likely by a licensing arrangement with a device company.Read moreRead less

We have developed a monoclonal antibody that blocks the C5a receptor in vitro, and completely shuts down disease in a mouse model of rheumatoid arthritis. We plan to develop this promising new antibody into a potent therapy to treat a range of chronic and acute inflammatory diseases. The antibody has been humanised and this will be tested in three models of inflammation (rheumatoid arthritis, sepsis and colitis) to determine the efficacy of the antibody, safety, the most effective dose, timing and route of administration. These studies are a necessary prelude to human clinical trials, which we hope to perform in approximately 24 months.Read moreRead less

Funding Amount

Summary
New therapies to treat cancers and inflammatory diseases are urgently required. Our aim is to develop a new treatment for cancer and inflammation, by blocking the chemokine receptor CXCR2 which is central to angiogenesis (blood vessel growth) and inflammation. We have produced a highly effective monoclonal antibody (mAb) inhibitor of CXCR2, that is suitable for preclinical and clinical development. The project aims to examine the efficacy of this mAb in mouse tumour models and inflammation.
