Defining Targets For Antifungal Stewardship In Immunocompromised Patients: Optimising Care And Safety
Funder

Funding Amount
$108,902.00
Summary
Patients with impaired immune systems are at risk of serious fungal infections. Antifungal medicines used to prevent and treat these infections can be toxic and costly. This project aims to review current antifungal use and improvement activities in place in health services, assess prescriber knowledge, and to evaluate current doses of echinocandin antifungals used in liver failure patients. This project will identify ways to improve antifungal use needed for effective and safe prescribing.
Exploiting The Pharmacokinetic And Pharmacodynamic Properties Of Bile Acid Receptor Agonists To Treat Liver Disease

Funding Amount
$653,952.00
Summary
We have generated preliminary data suggesting that chemicals made by the liver, called bile acids, act on fat cells to release a hormone called adiponectin. In liver disease adiponectin has favorable effects, including reducing liver inflammation and fibrosis (scarring). By using drugs that mimic the action of bile acids we expect that adiponectin production by fat cells can be increased, creating a new way to treat patients with chronic liver diseases.
A Study Of Artemisinin Combination Therapy Given At Delivery To Prevent Postpartum Malaria And To Young Infants To Treat Uncomplicated Malaria
Funder

Funding Amount
$788,850.00
Summary
The proposed studies will investigate the preventive value of a course of combination antimalarial treatment at delivery in pregnant women in malarial areas. The transfer of this treatment into breast milk and to the suckling infant will be investigated since this may protect the infant against malaria but also cause drug-related side-effects. These data will be used, with a study of combination treatment in infants with malaria, to optimise dose regimens in this vulnerable group.
Rescuing The Last-line Therapy Colistin Against Gram-negative ‘superbugs’: Increasing The Therapeutic Index By Attenuation Of Nephrotoxicity
Funder

Funding Amount
$498,631.00
Summary
Antibiotic resistance in Gram-negative ‘superbugs’ is presenting a significant global medical challenge. Colistin (polymyxin E) is increasingly used as the last treatment option even though the current use is suboptimal. Simply increasing the daily dose is not an option due to kidney toxicity. This project focuses on a new approach using antioxidants to ameliorate the potential for colistin-induced kidney toxicity, thereby allowing higher doses to achieve adequate bacterial kill in patients.
Targeting The Achilles' Heel Of Polymyxins: Eliminating The Nephrotoxicity
Funder
National Health and Medical Research Council
Funding Amount
$673,420.00
Summary
The world is facing a growing threat from the emergence of bacterial 'superbugs' that are resistant to all current antibiotics except the polymyxins. However, kidney toxicity occurs in up to 60% of patients receiving intravenous polymyxins. In this project, we will examine how polymyxins cause kidney toxicity then employ the obtained mechanistic information to decrease this adverse effect. Our study targets the urgent global unmet medical need, lack of new antibiotics for bacterial ‘superbugs’.
Physiologically-based Pharmacokinetics And Pharmacodynamics Of Therapeutic Stem Cells For Liver Disease
Funder
National Health and Medical Research Council
Funding Amount
$848,710.00
Summary
This project focuses on the challenging area of effective and optimal dosing cell-based therapy for liver diseases. We will investigate the fate and therapeutic effects of natural, modified and artificial therapeutic cells in the body and in liver regions using a physiologically-based kinetic model. Our key goal is advance cell therapy by providing a better understanding and dosing guidelines.
