$368,562.00
Summary
My research will determine the best way to give antibiotics to treat Staphylococcus aureus, one of the most common causes of infection in children. This includes finding out if we can provide highly effective treatment with antibiotics given by mouth instead of through a drip, and with fewer doses each day, so we can treat kids at home instead of in hospital. I will also explore new ways to use common antibiotics to treat antibiotic-resistant infections.
Effects Of Ageing On Hepatic Drug Clearance And Mechanisms Of Drug Induced Liver Disease

Funding Amount
$581,892.00
Summary
With increasing age, there is increase in disease, for which medications may provide benefit, and an increase in the risk of adverse drug reactions, even after considering the increase in medication use by older people. We will investigate how the liver clears drugs from the blood in old age. This will guide dosing of medications for older people. We will also study how drugs injure the liver in old age and test interventions to prevent this toxicity.
A Multicentre Feasibility Study Of Partial Breast Irradiation Using 3D Conformal Radiotherapy For Early Breast Cancer

Summary
Breast conserving therapy (BCT) is an accepted treatment option for most women with early breast cancer. Whole breast irradiation (WBI) after breast conserving surgery substantially reduces the risk of breast recurrence. However, the prolonged 5-7 week course of WBI substantially decreases the quality of life (QoL) experienced by women and is a logistical problem particularly for the elderly and women who reside far from a radiotherapy (RT) facility.

Whole breast irradiation (WBI) after breast conserving surgery substantially reduces the risk of breast recurrence. However, the prolonged 5-7 week course of WBI substantially decreases the quality of life (QoL) experienced by women and is a logistical problem particularly for the elderly and women who reside far from a radiotherapy (RT) facility. In order to improve the access and convenience of BCT, accelerated partial breast irradiation (APBI) is being investigated. Research shows that 75% of the breast recurrences occur at the tumour bed after BCT implying that in selected women, RT may be limited to the tumour bed only. By limiting the breast volume irradiated, it is feasible to accelerate radiation dose delivery and reduce overall treatment time. In addition, a shorter schedule permits more efficient use of RT resources. To determine if APBI could replace WBI as standard of care for selected women with early breast cancer treated with BCT, it is necessary to demonstrate its technical feasibility and equivalence of outcomes compared to WBI. This study investigates the feasibility, toxicity, cosmetic outcome, local control and QoL of women with early breast cancer treated with APBI using a novel technique. It uses advanced 3-dimensional RT planning and multiple fields shaped to conform to the target volume (tumour bed) and spare the normal organs. It is more likely than the other modalities to be adopted as the preferred APBI technique in Australia because it uses equipments readily available in most RT centres and being non-invasive, is likely to be preferred by patients. However, its feasibility in multiple Australian centres with varying RT equipments is unclear. Given the current high level of international interest, it is timely to conduct this feasibility study in preparation for large scale research to determine if APBI may replace WBI in BCT.Read moreRead less
Clinical Pharmacology Of Methadone During Induction Onto Maintenance Treatment.

Funding Amount
$422,310.00
Summary
Heroin addiction can be very successfully treated by substituting heroin with methadone. The transition of stopping heroin and starting methadone is risky and can be associated with death. This application seeks to explore the mechanisms of the increased risk during this transition period so that appropriate management strategies might be instituted.
Improved Patient Outcomes Through Dosage Individualisation Of The Newer Immunosuppressant Drugs

Funding Amount

Summary
After organ transplantation, recipients need to take medicines continually to stop their immune system from rejecting their new organ. This treatment with immunosuppressant drugs is vital for long-term success of their graft. However, too many people are losing their transplant or are experiencing drug toxicity or infection due to poorly managed immunosuppression. The project aims to accurately define the best way to dose newer immunosuppressant drugs in Australian transplant populations.
Optimizing Outpatient Parenteral Antibiotic Therapy To Support Hospital-in-the-home Program Across The Unique Environmental Conditions Of Australia

Funding Amount
$645,205.00
Summary
This project aims to solve problems associated with stability and dosing of antibiotic infusions given to patients in their homes, to support decision making by doctors and regulators. Currently, there is a lack of adequate data that complies with contemporary requirements. We will study infusion preparation both in laboratory settings and in ‘real-life’ conditions while being used by patients. We will enhance the stability of antibiotic preparations and optimize doses for effective treatment.
X-RATE: A Novel Radiation Detector Platform To Realize New Opportunities In Radiotherapy At The Australian Synchrotron

Funding Amount
$347,541.00
Summary
Microbeam Radiation Therapy (MRT) is an emerging X-ray radiosurgery modality that offers new hope for the treatment of brain cancer and other human brain diseases. A tissue equivalent radiation dosimetry system is essential for upcoming MRT human trials to precisely verify treatment plans. We are recognized world leaders in real-time silicon detector instrumentation for radiation dosimetry. We plan to develop and demonstrate X-RATE, the X-ray Real-time Active Tissue Equivalent dosimeter.
First Ever System To Continuously And Directly Measure The Internal Anatomy To Guide Breast Cancer Radiation Treatment Under Deep Inspiration Breath Hold

Funding Amount
$409,766.00
Summary
We propose a first ever system to continuously and directly measure the internal anatomy of the patient during radiotherapy of left sided breast cancer to ensure correct position of patient and radiation beam. The proposed method involves no additional radiation dose to the patient. It relies on existing components of modern radiation treatment machines, requiring no additional equipment, which will make it easy to implement widely.
