A project to develop a spider venom derived drug to treat heart attack and protect donor hearts is set to enter clinical trials, following a $17.8 million funding boost from the Medical Research Future Fund (MRFF).

Led by the , the project would assess the potential of Hi1a 鈥� a peptide in the venom of the K鈥檊ari funnel web spider聽鈥� as a treatment to prevent heart damage during a heart attack or donor heart procurement over a four-year trial.

鈥淥ur team showed that in animal models, Hi1a protects the heart from damage sustained due to lack of oxygen during a heart attack or during donor heart retrieval,鈥� said Professor Glenn King from UQ鈥檚 Institute for Molecular Bioscience (IMB).

鈥淭his MRFF funding will enable us to undertake human clinical trials to test a miniaturised version of Hi1a as a drug to treat heart attack and protect donor hearts during the retrieval process.

鈥淚f successful it will improve patient survival and quality of life, dramatically expand the pool of donor hearts available for transplantation and significantly reduce healthcare costs.鈥�

IMB鈥檚 Associate Professor Nathan Palpant led the studies showing the efficacy of Hi1a in cardiac disease models, and said a drug to treat heart attacks would have significant impact.

鈥淐oronary heart disease is the leading cause of death in Australia. Almost 60,000 Australians are hospitalised with a heart attack every year and 7000 will not survive,鈥� Palpant said.

鈥淥f those that do survive, a quarter will develop debilitating heart failure within one year of their attack.

鈥淎 transplant is the only cure for heart failure but there鈥檚 a severe worldwide shortage of donor hearts, partly due to the damage that occurs during the retrieval process.

鈥淒espite the huge socioeconomic burden of heart attack and heart failure, there is not a single drug to limit the loss of heart cells during an attack or to protect donor hearts聽鈥� our team hopes to change this.鈥�

The clinical trial is the culmination of years of work by the research team investigating the use of Hi1a as a treatment for heart attack and stroke, and to increase the viability of donor hearts.

The team includes researchers from UQ, the Victor Chang Cardiac Research Institute and the Baker Heart & Diabetes Institute as well as clinicians at St Vincent鈥檚 黑料吃瓜群网 in Sydney, the Alfred 黑料吃瓜群网 in Melbourne and The Prince Charles 黑料吃瓜群网 in Brisbane.

The project will also involve Brisbane-based biotech company Infensa Bioscience, where Glenn King is Chief Scientific Officer and Nathan Palpant is Head of Biology.

Research showing that Hi1a had met critical benchmarks towards becoming a treatment after passing a series of preclinical tests was published in 2024 in The European Heart Journal.
