Our clinical trials

More than 130 sites worldwide are participating in our trials, bringing together leaders in anaesthesia research. We want to build on the success of our multi-centre research by engaging all accredited sites to participate in our trials. 

We believe fellows and trainees supporting multi-centre research to improve the evidence base to guide safe and effective care should be core to their role as a medical specialist, so they and their patients can reap the many benefits of participating in clinical research. 

Running a large number of trials requires recruitment of thousands of patients and this work cannot be done without the dedication of people at our sites across the entire network. 

We aim to increase the capacity of our network and are calling for new sites - including paediatric, private, rural and regional hospitals - to join our trials to enable a higher recruitment rate and allow more trials to be conducted and completed on time and within budget. We welcome new sites to join.

MASTERSTROKE

The MASTERSTROKE study: Management of Systolic blood pressure during Thrombectomy by Endovascular Route for acute ischaemic STROKE

MASTERSTROKE is a pragmatic, prospective, double blind, randomized, multicentre clinical trial. The aim is to assess the influence of induced hypertension (IH) during general anaesthesia for thrombectomy involving stroke patients. The primary outcome is functional recovery at 90 days as measured by the modified Rankin Scale. Anaesthetists will be asked to target a systolic blood pressure target of 140 mm Hg or 170 mm Hg from case start until the target vessel is recanalised or case completion if recanalisation is not achieved. The trial has received a total of $NZ490,000 from the Auckland District Health Board Research Trust, The Auckland Medical Research Foundation and the Neurological Foundation of New Zealand in order to fund the project office, database and New Zealand recruitment. Dr Doug Campbell is supported by a two year Senior Clinical Research Fellowship from the Neurological Foundation of New Zealand to help administer the trial.

Recruitment has started at Auckland City Hospital despite the COVID-19 pandemic. We have recruited 90 patients to date. Christchurch Hospital has their regulatory approvals in place and is about to start recruiting. University Medical Centre, Groningen, Netherlands have been delayed by the international shutdown but have secured local funding and are proceeding with ethics application. The Australian ethics application is being initiated by Allison Kearney and David Highton at Princess Alexandra Hospital in Brisbane. Australian sites wanting more information or wishing to register interest.

Chewy

The Chewy Trial is a multicentre, randomised, controlled trial of chewing gum vs. ondansetron for post-operative nausea and vomiting in women and girls having laparoscopic or breast surgery. We thank all our sites and collaborators for their  hard work during 2020 in continuing trial recruitment, we are now back up and running at full steam! Chewy is over one-third of the way to completion, with 409 patients recruited and 111 randomised across 16 active sites in Australia and New Zealand (target: 272 randomised patients). We welcome more sites interested in joining the Chewy team.

The primary hypothesis for the study is that chewing gum (one stick of Wrigley's peppermint-flavoured gum, chewed for 15 minutes) is non inferior to 4mg IV ondansetron in achieving complete cessation of nausea, retching and vomiting postoperatively, within two hours of administration, with no recurrence of nausea and no need for rescue medication. This has the potential to dramatically change the management of one of the most common complications of anaesthesia worldwide.

POISE-3

The Perioperative Ischemic Evaluation-3 (POISE-3) trial will examine the safety and efficacy of tranexamic acid and the effect of a hypotension-avoidance strategy on ischaemic and bleeding endpoints in major noncardiac surgery in 10,000 participants.

We have reached more than 75 per cent of our target recruitment with more than 7650 participants recruited globally from 103 sites. In Australia and New Zealand, 557 participants have been recruited from our 20 activated sites. If you are interested in post-op delirium and cognition then the CogPOISE-3 substudy may interest you. More than 1550 patients have been recruited to CogPOISE-3 and there is still plenty of time for sites to part.

CLIP-II

Freezing platelets using DMSO as a cryoprotectant extends shelf-life from five days to two years.

Following a successful pilot study in four hospitals (Transfusion, 2019), the CLIP investigators (a collaboration of the ANZCA CTN, ANZICS CTG, Australian Defence Force, Australian Red Cross Blood Service and Australian civilian hospitals) designed a definitive trial that will recruit 808 high-risk cardiac surgery patients, to achieve 202 patients actually transfused platelets. A platelet risk prediction tool, the Australian Cardiac Surgery Platelet Transfusion (ACSePT) score, incorporating relevant variables, has been developed using local data.

The protocol has ethics approval, and all study procedures are in place. Sufficient platelets will have been manufactured for the first patients to be enrolled in early 2021. Engagement with twelve selected study sites has progress through 2020. In New Zealand, an investigative team led by Dr Shay Mc Guinness and Associate Professor Rachael Parke, has received funding from the NZ Health Research Council (HRC) to run a parallel protocol using cryopreserved platelets manufactured by a slightly different technique.

For more information on the CLIP-II study, please refer to the ANZIC-RC webpage or clinicaltrials.gov registration NCT03991481

DECS-II

The DECS-II trial is a multicentre, pragmatic, assessor-blinded, randomised trial of dexamethasone (1mg/kg, single dose) versus placebo, in patients undergoing cardiac surgery, employing a novel, highly efficient trial design. The trial is led in Australia by Professor Paul Myles, with Dr Stefan Dieleman and Dr Lieke Verheijen in Utrecht, Netherlands. Total sample size is 1400 patients from each county. Australia has recruited 860 patients from The Alfred hospital, Monash Medical Centre, Geelong Hospital, Royal Adelaide and Westmead Hospital. The Netherlands is recruiting at one centre with three further sites in ethics.

LOLIPOP

The Long-term Outcomes of Lidocaine Infusions for persistent PostOperative Pain in patients undergoing breast cancer surgery (LOLIPOP) trial 

In a landmark achievement, a team led by Deputy Chair of the ANZCA Clinical Trials Network, Professor Tomás Corcoran, secured a $A4.3 million grant from the Medical Research Future Fund to perform the LOLIPOP trial. The five year LOLIPOP trial is a large (n=4400) pragmatic, multicentre, randomised, stratified, controlled, superiority trial evaluating the effect of lidocaine infusions in the intra- and postoperative periods on the incidence of moderate or severe chronic post-surgical pain (CPSP) at one year in patients undergoing elective breast cancer surgery. Secondary outcomes will include analgesic efficacy (pain scores), psychological and quality of life outcomes, the influence of pharmacogenomic profile on efficacy, and cost-effectiveness.

Study hypothesis: The administration of a lidocaine infusion intraoperatively and up to 24 hours postoperatively reduces the incidence of moderate or severe CPSP following breast cancer surgery compared with placebo.

Please email Professor Tomas Corcoran if you are at all interested in being involved, with your contact details and any questions.

TRICS IV

Transfusion Requirements in Cardiac Surgery (TRICS IV) trial

The TRICS IV study is designed to determine whether a liberal transfusion strategy is superior to a restrictive strategy in cardiac patients < 65 years. TRICS IV will incorporate an innovative pragmatic Bayesian design to include patients recruited to TRICS III in its sample size estimation and analysis. It will also include the option of physiologic triggers for transfusion, in addition to the above Hb based thresholds. As for TRICS III, this study is being led by Professor David Mazer’s group from Canada with Canadian Institutes of Health Research (CIHR) funding and will involve an international collaboration. We have secured National Health and Medical Research Council MRFF International Collaborative Trials funding of $A870k for the Australian arm of this study, which will include a local iron availability sub-study. We plan to recruit 500 adult cardiac surgical patients (Euroscore ≥ 6) through multiple Australian sites over three years. Those involved with TRICS III will find the trial conduct and management very familiar.


Please email Professor David Scott if you are interested in being involved, with your contact details and any questions.
