Help us find a cure

Research Project

Cure 4 Cystic Fibrosis aims to find a cure for CF by supporting promising areas of scientific research. To date, this has seen the Foundation support the research being undertaken by the Adelaide CF Airway Gene Therapy Research Group, which is focussed on a gene therapy approach to treat and potentially cure cystic fibrosis (CF) airway disease. If the techniques and strategies being developed by the team are successful, this research has the potential to improve and save the lives of the 3,000 people living with CF in Australia and more than 70,000 people worldwide.

The group employs a world-leading gene transfer approach. They use an especially modified virus to take a correcting gene into the airway, supplementing the defective gene that causes CF airway disease. The cell then takes over the job of producing the normal airway physiology.

The most exciting aspect of the work is that although this approach should produce long term gene therapy treatments, it is also a potential cure for the airway disease in CF. It is designed to correct airway stem cells. This means that as new airway cells are produced by the body they will have the corrected gene operating within them. Success in this research project means that people living with CF airway disease will, for the first time, be able to live well and potentially be free of this disease.

Research undertaken by the team has shown that their gene transfer approach is successful in several animal models. The next challenge is to continue to develop their work to the point where they can commence trials of the gene transfer approach in cystic fibrosis patients.

Research Highlights

The research team has made a number of significant advances, particularly around the use of the actual gene transfer approach. Of particular importance was their work that showed the ability of the research team to produce a properly functioning expression of the gene that corrects the cystic fibrosis defect for more than 12 months. No other research group worldwide had been able to attain such extended gene correction.
