About

Professor Jonathan Golledge is Head of the Queensland Research Centre for Peripheral Vascular Disease and its pre-clinical arm The Vascular Biology Unit (VBU) at the School of Medicine and Dentistry, James Cook University. Professor Golledge joined JCU in 2002 and established the Vascular Biology Unit with the aim of carrying out research intended to be translated into improved management of aortic aneurysm and other peripheral vascular conditions. We continue to seek high quality students and researchers to join our group. Trained as a vascular specialist, Professor Golledge took 2 years out of specialist training to obtain experience in research techniques as part of a Cambridge MChir (Doctoral equivalent), UK. His research commitment is illustrated by a large number of presentations at International and National meetings and publications in peer-reviewed journals, including a large number in top specialised journals.

Professor Golledge holds a conjoint position between the School of Medicine and Dentistry and Queensland Health, where he works as a vascular surgeon. In addition to providing a high quality clinical service his principal aspiration is to improve management of peripheral vascular diseases. The research impact of this is evidenced by external grant support from the NIH, NHMRC, Queensland Government, NHF and other bodies. Of note in 2010 Professor Golledge led a successful bid to establish a NHMRC funded centre of research excellence for Peripheral Vascular Disease.

The Metformin Aneurisym Trial (MAT)

Indicative Funding
$4,997,653 over 5 years
Summary
20 million people worldwide and 100,000 Australians have an abdominal aortic aneurysm (AAA). The main complication of AAA, aortic rupture, leads to 200,000 deaths/year worldwide. AAA prevalence and mortality rates in Australasia are 4-fold higher than the world average, so research to improve management is a key priorty. Most AAAs are detected when theya re small, when an effective treatment would prevent the need for surgery. There is currently no effective drug therapy for AA, and 70% of small AAAs grow to a size requiring surgical repair which carries inherent risks of death and major complications. A large amount of observational data from patients and laboratory models suggest that metformin may be an effective drug therapy for AAA. The metformin aneurysm trial (MAT) will be a large-scale, multi-centre randomised trail done as a collaboration between investigators in Australia, New Zealand, Swden and the United Kingdom across 55 sites over a 5 year trial period. Patients with AAA measuring between 39 and 49mmm in diameter will be enrolled over 24 months, assiged at random to 1500mn of metformin extended release (XR) or placebo each day followed for a mean of 3.5 years. The primary outcome will be AAA rupture or repair. The sample size of 1,954 will provide 90% pwer (p=0.05) to detect a 25% or greater reduction in the relative risk of the primary outcome. A positive finding from MAT would identify metformin as the first effective medical treatment for AAA. Since metformin is low cost, safe and available worldwide, the trial will have direct clinical implications for tens of millions of people around the world for whom no preventative therapy is currently available.

Peak Wall Stress as a prognostic indicator of abdominal Aortic Aneurysm rupture risk

Indicative Funding
$50,000 over 2 years
Summary
Abdominal Aortic Aneurysm (AAA) affects 20 million people worldwide and 100,000 people in Australia. Annually, AAA rupture leads to 200,000 deaths worldwide and 2000 deaths in Australia. In clinical practice, maximum AAA diameter is the preferred surrogate measure for disease progression and rupture risk, and is used to guide surgical intervention. Approximately 10% of AAAs will rupture before they reach the current threshold for repair, whereas 60% of large AAAs remain stable during their lifetime, suggesting that diameter alone is an imperfect tool to decide which AAAs require surgical intervention. The specific aims of the project are Aim 1: To investigate if PWS is greater in patients with ruptured compared to intact AAAs matched for diameter; Aim 2: To evaluate the impact of a common anti-hypertensive medication {Telmisartan) on PWS and rupture risk in patients with small AAAs.

Assessment of the efficacy of a novel treatment for Peripheral Artery Disease (PAD)

Indicative Funding
$50,000 over 2 years
Summary
Blockage of leg arteries (peripheral artery disease - PAD) leads to severe exertional leg pain (intermittent claudication), impaired walking ability, reduced health-related quality of life, and high risk of amputation and death. Multiple lines of evidence suggest that metformin, a cheap and safe medication, promotes formation of new vessels, improves microcirculation and muscle function,s and limits pain.

Testing a novel treatment for diabetes-associated ischemic foot ulceration

Indicative Funding
$60,000
Summary
5000 Australians with diabetes have a leg amputations each year. This project investigates a novel drug therapy approach to reducing the need for leg amputations within an established rodent model. The aim of the study is to assess if administration of a direct activator of adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK) will promote healing within a rat model of diabetes and limb ischaemia-associated foot ulceration

Metformin for treating peripheral artery disease-related walking impairment (MERIT)

Indicative Funding
$75,000
Summary
Blockage of the lower limb arteries (peripheral artery disease; PAD) leads to severe leg pain, walking impairment, and a substantial risk of leg amputation and death. Approximately 200 million people worldwide and approximately 1 million Australians have blocked leg arteries. This problem has recognised treatment deficiencies in comparison to other common diseases, including the absence of effective medications to increase blood supply to the legs, reduce leg pain, improve walking ability and reduce the risk of major amputation. Multiple lines of evidence suggest that metformin, a cheap and safe medication, promotes formation of new vessels, improves microcirculation and muscle function, and limits pain. In preliminary studies, metformin significantly increased blood supply to the limb of a pre-clinical model of blocked leg arteries. We have also associated metformin prescription with a 4-fold reduction in the rate of major lower limb amputation in patients with blocked arteries. This placebo-controlled, randomised clinical trial will examine the efficacy of metformin in improving walking ability in patients with blocked leg arteries over 6 months. Positive findings from this trial will identify a new treatment for a problem that affects 10-20% of adults aged over 50 years.

Blocking the factor XII-kallikrein pathway to limit abdominal aortic aneurysm

Indicative Funding
$686,995 over 3 years
Summary
Abdominal aortic aneurysm (AAA) is estimated to be responsible for 2000 sudden deaths each year in Australia. AAAs can be readily identified when they are small but there are currently no effective medical therapies to limit complications in patients that have such AAAs. We hypothesise that interventions inhibiting the FXII-kallikrein pathway will limit progression of established AAAs within pre-clinical models and have other important secondary benefits such as the reduction of atherosclerosis progression.

Coding and non-coding circulating RNAs associated with the presence and rapid expansion of abdominal aortic aneurysms

Indicative Funding
$250,000 over 2 years
Summary
Deoxyribonucleic Acid, or DNA is the molecule that comprises genes. The mix of genes you have may mean you are likely to have, or be more prone to develop, particular conditions. The way the information encoded by DNA is converted into outcomes (such as a medical condition) is via the action of Ribonucleic Acid, or RNA. This project aims to identify RNAs in blood associated with the presence or rapid growth of abdominal aortic aneurysms - potentially lethal balloonings of the largest artery in the abdomen, the abdominal aorta. This may yield new methods of diagnosing and treating aneurysms.
