How Do We Treat the Untreatable?  
SickKids VS Rare Disease



Five-year-old Michael is one of less than 100 people in the world with SPG50, an ultrarare genetic disease. In March 2022, a SickKids team dosed Michael with the first-ever gene therapy for SPG50 in an unprecedented clinical trial. We tell the remarkable story of what it took to deliver a customized drug for Michael’s particular genetic variant, and what it means for SickKids’ vision of precision medicine. 





Michael with his mom, Georgia. It took a year for Michael to get a diagnosis, and three years to get him a treatment.


When Michael was around four months old, his parents noticed he wasn’t lifting his arms or grabbing for toys. So began the diagnostic odyssey.
WSPG50 is a neurodegenerative disorder, which means as Michael grows, he’ll lose function of his limbs and experience cognitive decline.


Michael’s dad, Terry, led a three-year quest to get a drug made for Michael and other kids with SPG50.

 

Michael does regular physiotherapy to keep his limbs strong and hopefully stave off the progressive spasticity that comes with SPG50.
