Over the past few years, the MS research community has been following developments in a new class of therapies called Bruton's tyrosine kinase inhibitors (BTKis). At ECTRIMS 2024, the results of two tolebrutinib trials were presented as late-breaking abstracts by Dr. Robert Fox, Neurologist at the Mellen Center for Multiple Sclerosis at Cleveland Clinic in the US, and Dr. Jiwon Oh, Neurologist at St. Michael's Hospital at the University of Toronto. The full results were recently published in The New England Journal of Medicine. In this episode, host Brett Drummond of MStranslate spoke with Drs. Oh and Fox about the outcomes and what they mean for people with MS.
