Funding Amount
$513,896.00
Summary
Respiratory infections caused by multidrug-resistant Gram-negative bacteria are major health problems for Australians. Colistin is the last-resort defense in most cases. However, parenteral administration of colistin will cause serious side effects. This proposal applies an interdisciplinary approach using aerosol particle engineering, functional lung imaging and antimicrobial pharmacology to develop and characterise novel inhaled powder formulations of colistin and its rational combinations.
Novel Inhalation Formulation Of Bacteriophages Against ‘superbugs’ Causing Respiratory Infections

Funding Amount
$563,621.00
Summary
Emergence of superbugs has led to life-threatening respiratory infections that are resistant to most antibiotics. There is an urgent need for alternative treatments not relying on antibiotics. Bacteriophages (or ‘bacteria eaters’) are natural predators of bacteria and are unaffected by antibiotic resistance. This multi-disciplinary project will develop novel therapeutics using inhaled bacteriophages against bacterial infections in the lungs.
Engineering Powder Aerosols Of Antibacterial Nanomedicines For Treatment Of Respiratory Infections

Funding Amount
$195,338.00
Summary
This project aims to apply cutting-edge nanotechnology to develop new inhalation therapy for respiratory infections by delivering antibiotics directly to the lungs. The expected outcomes of this work are more efficacious, safer and cost effective treatments for patients suffering from respiratory infectious diseases such as pneumonia.
CSI-Sydney: New Technologies To Treat Chronic Sinus Infection

Funding Amount
$412,213.00
Summary
Chronic sinus infection (CSI) is prevalent and results in severe discomfort and pain for many Australians; yet amazingly, has no specific cure or effective treatment. Our multi-disciplinary research team and an Australian health and medical research company, (AFT Pharmaceuticals) have partnered to develop a novel device that specifically targets the sinuses and a formulation capable for simultaneously removing mucus, dispersing biofilms and killing bacteria in the nasal cavities.
Targeting Cystic Fibrosis Using A Novel Inhalation Therapy

Funding Amount
$421,545.00
Summary
Currently treatments for cystic fibrosis infection are via oral, intravenous or lengthy inhalation processes. This can lead to significant side effects, consequent poor patient compliance, and limited therapeutic efficacy. We will develop and test a novel high-dose inhalation dry power device containing an antibiotics for the rapid treatment of infection in cystic fibrosis therapy.
Targeting Bacterial ÏsuperbugsÍ By Innovative Combination Dosing Strategies And New Antibiotics

National Health and Medical Research Council
Funding Amount
$463,650.00
Summary
This research project will elucidate the mechanistic basis to optimally combine available beta-lactam antibiotics to prevent resistance of gram-negative bacterial ïsuperbugsÍ. These mechanistic insights will be utilised to develop novel antibiotics that are active against these multidrug-resistant bacteria. The interdisciplinary project will substantially contribute to solving the global crisis due to multidrug-resistant bacteria and inform the design of effective new antibiotics.
Targeting Hypermutable ‘superbugs’ In Chronic Respiratory Infections By Optimised Antibiotic Combination Dosage Regimens
Funder
National Health and Medical Research Council
Funding Amount
$697,731.00
Summary
Many bacterial ‘superbugs’ can increase their mutation rate, i.e. become hypermutable, and thus rapidly become resistant to multiple antibiotics. Chronic lung infections with hypermutable bacteria cause increased ill-health and death in patients and current treatments do not work well. We will develop improved treatments using combinations of available antibiotics. This project will provide guidance to doctors on how to treat infections more effectively and minimise emergence of resistance.
Combating Bacterial ‘superbugs‘ By Innovative Dosing Strategies That Combine Available Antibiotics To Prevent Resistance
Funder
National Health and Medical Research Council
Funding Amount
$547,694.00
Summary
As resistant bacterial ‘superbugs’ are among the 3 most serious threats to global health and as new antibiotics are lacking, innovative strategies to prevent bacterial resistance are urgently needed. This proposal will yield molecular insights on optimal combinations of current beta-lactam antibiotics to maximise bacterial killing without resistance. This project will provide guidance to physicians on how to optimally combine available beta-lactam antibiotics to prevent bacterial resistance.
