Toronto Patient's HIV Cure: A Rare Success

0:00It's April 26th, from your city to your ears. This is Canada News Today, powered by AI. A 62-year-old dude from Toronto, known as the Toronto patient, might soon join the rare club of folks cured from HIV. He got a bone marrow transplant back in 2021 to fight acute myologinous leukemia at Princess Margaret Cancer Center. The donor stem cells carried a Delta-32 mutation in the CCR-5 gene, which blocks HIV from infecting cells. He'd been living with HIV since 1999, that's 27 years on anti-retroviral meds to keep it in check. Doctors stopped his treatment in July 2025, and by April 20th, 26th, the virus was undetectable. If it stays that way through the end of 2027, about 2 and a half years off meds, he'll officially be called cured. Docs presented the case at the Canadian Association of HIV Research Conference in Winnipeg, and reactions poured in. The patient's HIV clinic director said his new immune system can't be touched by the

To find the right donor, they searched family first, then hit global registries with 47 million potentials from Germany and the US. They scored three matches with the mutation, wiping out his old immune system, the cancer, and leaving HIV powerless against the new one. This isn't a go-to fix for HIV since it was all about treating the cancer, but it spotlights why donor registries matter big time. More matches like this, fuel research to beat the virus for good, and cut the stigma.
