In developed countries Asthma ranks among the most common chronic illnesses. Over two million Australians now have this condition and the cost to our community is estimated to be in excess of $720 million per annum. In 1996 researchers at The Walter and Eliza Hall Institute discovered a new member of the cytokine receptor family, IL-13Ra1, which further research has strongly implicated in the pathology of this disease.

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.
The Respire_ System: Portable Pulmonary Delivery Platform For Rapid, Flexible And Highly Efficient Treatment Of Elderly, Paediatric And Physically-Compromised Patients With Chronic Respiratory Diseases

Summary
The development of a low-cost miniature drug delivery platform for the treatment of chronic respiratory diseases is proposed. The portable device has already been shown to be significantly more efficient than currently available asthma inhalers. In addition, the device offers the possibility of dose adjustment to account for patient variability, such as age and disease severity, as well as a reduction in patient intervention, thus making it more appropriate for patients unable to self-medicate.
In Vitro And In Vivo Assessment Of The Funhaler -an Innovative Therapeutic Device For Children

Summary
Aerosol therapy is the most effective form of treatment for children with respiratory diseases such as asthma. While optimising aerosol delivery systems has an important role in increasing the efficacy of asthma therapy, ensuring patient compliance is often the most difficult part of the clinician's role, particularly in the paediatric age group. An innovative small volume spacer device (Funhaler) developed by a West Australian company (InfaMed, Ltd) may help overcome this problem.

While optimising aerosol delivery systems has an important role in increasing the efficacy of asthma therapy, ensuring patient compliance is often the most difficult part of the clinician's role, particularly in the paediatric age group. An innovative small volume spacer device (Funhaler) developed by a West Australian company (InfaMed, Ltd) may help overcome this problem. The Funhaler incorporates a spinning toy attached to the outside of the spacer. The toy is activated when the patient breathes through the spacer. The device has been designed to encourage children to co-operate when their asthma therapy is being delivered. The Funhaler is currently in the late development stage. We propose, firstly, to carry out in vitro assessments of drug delivery from the Funhaler compared to the two most widely available small volume spacers: the Aerochamber Plus (Trudell, Canada) and the Breath-A-Tech (Scott-Dibben, Australia). These assessments will be carried out to meet the standards of regulatory bodies worldwide (including the FDA). Secondly, we propose to perform extensive in vivo studie: filter studies to assess drug delivery to the patient; deposition studies to measure drug deposition in the lungs; and a pilot clinical trial to assess the efficacy of the device during medium to long-term use in children aged 2-8 years.Read moreRead less
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.

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. 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
