A tech entrepreneur has created a personalised cancer<\/a> vaccine for his dog, a breakthrough experts say could shape the future of human medicine. <\/p>\n

Sydney<\/a> man Paul Conyngham adopted his ‘best mate’ Rosie, an eight-year-old staffy-Shar Pei cross in 2019. <\/p>\n

In 2024, the canine was diagnosed with mast cell cancer after large tumours started to appear on one of her back legs. <\/p>\n

Mast cell cancer is the most common skin cancer found in dogs, and often appears as lumps, nodules or masses in the skin. <\/p>\n

Mr Conyngham spent thousands on veterinary chemotherapy for Rosie, which slowed the spread of the tumours but failed to shrink them. <\/p>\n

The tech expert decided to turn to ChatGPT<\/a> to ask for possible cures for the cancer, later using the technology to sequence Rosie’s DNA and design a world-first custom mRNA vaccine for the sick pooch. <\/p>\n

‘We took her tumour, sequenced the DNA, we converted it from tissue to data, and we used that to find the problem in her DNA and then develop a cure based off that,’ Mr Conyngham told the Today Show on Saturday. <\/p>\n

‘ChatGPT assisted throughout that entire process.’<\/p>\n

Mr Conyngham then got in touch with P\u00e1ll Thordarson, the director of the renowned UNSW RNA Institute, who used the data to create the world-first vaccine. <\/p>\n

Dr Thordason told Today that although he had worked with similar mRNA for years, he was worried the technology would take too long to develop and help Rosie.  <\/p>\n

‘Once we had the sequence that Paul designed, it was less than two months until we handed it over to Paul, to the vet.’<\/p>\n

Mr Conyngham said it took about a month to see results from the vaccine, which to date has shrunk the tumour by 75 per cent. <\/p>\n

He said Rosie was losing her mobility in December, but by January he was shocked to see her jump over a fence to chase a rabbit. <\/p>\n

‘I think it’s added considerable life and healthspan to Rosie,’ he said.<\/p>\n

Dr Thordason said the world-first vaccine ‘absolutely’ could be used to treat human cancer patients in the future. <\/p>\n

‘There are companies including Moderna that are working on personalised cancer vaccines, but I think what this taught me is two things; We can actually do this here, we don’t have to necessarily rely on foreign companies<\/a> to help us do this.<\/p>\n

‘That means we can democratise this technology in Australia. And we can also use it for other diseases, neurological diseases, for instance.’<\/p>\n

Mr Conyngham said the pair were currently sequencing a tumour that didn’t respond to the vaccine to find out why it was resistant. <\/p>\n

He explained why he was prepared to spend so much time and money finding a cure. <\/p>\n

‘Rosie is my best mate,’ he told the show. <\/p>\n

‘She’s been with me through really tough times, through a breakup, through hard business deals and walks in the forest. <\/p>\n

‘So when she was handed this sentence, I felt I had to do my part for her as well.’<\/p>\n<\/div>\n
