Changing the outlook for people with Parkinson’s disease
Professor Grant Dewson from WEHI will co-direct the team to advance precision medicine and biomarker discovery for Parkinson’s disease, alongside Professor Glenda Halliday from the University of Sydney.
Parkinson’s was first discovered in 1817 and is now the fastest growing neurodegenerative condition in the world. Why are there no drugs to stop or slow its progression?
Parkinson’s has no single cause. It is complex, with links to several gene mutations as well as environmental influences. Currently there is no cure and the only drugs available help control the wide range of symptoms people with Parkinson’s experience daily.
By the time someone is diagnosed it’s estimated they have already lost over 50% of the brain cells that produce dopamine. The exact cause of these losses is not yet fully understood.
These factors combined, and the expense of drug discovery projects, make the search for new medicines difficult, but new technology along with multi-discipline collaboration is accelerating research.
What are precision medicines and how do they differ from more traditional medicines?
Traditional medicine uses a one-size-fits-all approach. Everyone with a particular condition will be prescribed the same drug that might work well for some and not for others.
Precision medicine tailors the treatment to an individual guided by factors including genetics, environment and lifestyle. This patient-centered approach is designed to make medicines more effective and minimise side-effects, and is now used in many cancer therapies.
Why is the search for biomarkers for Parkinson’s so important?
Biomarkers are measurable disease indicators, ideally by a simple test of blood or urine.
Having a biomarker that will identify Parkinson’s in its early stages before symptoms become apparent will allow people to access treatments that more effectively delay the progression of the disease. It could also lead to a national screening program like we have for bowel and breast cancers.
Biomarkers are also important for tracking disease progression, individual responses to treatments and the effectiveness of new disease-modifying drugs in clinical trials.
Looking forward five years to the end of this project, what do you hope to have achieved?
This Centre of Research Excellence provides important foundations for closer collaboration across Parkinson’s research, enabling us to leverage combined resources, personnel and expertise.
Through this collaborative approach we aim to better understand the complexities of Parkinson’s and progress new disease-modifying therapies and biomarkers towards the clinic – helping improve the lives of the more than 200,000 Australians living with Parkinson’s today and future generations.
The Centre of Research Excellence for Parkinson’s Disease: Advancing Precision Medicine is led by WEHI and the University of Sydney in partnership with the Florey Institute of Neuroscience and Mental Health, University of Tasmania, Monash Health, Neuroscience Research Australia and the Royal Melbourne Hospital.
