Predictors of initiating high-efficacy vs. platform therapies as first-line disease-modifying treatment in multiple sclerosis

First-line use of heDMTs in Saudi Arabia has increased substantially over recent years, particularly among patients with cerebellar onset. While disability outcomes were similar between treatment groups, initiating heDMTs conferred clear advantages in persistence and tolerability. These findings reinforce the paradigm shift toward early intensive MS management and highlight the need for broader access and guideline-driven implementation of heDMTs in the region.
