Using a recently published model generated by an advisory board from the United States, as a framework, The Canadian Multiple Sclerosis Working Group (CMSWG) developed practical, evidence-based recommendations on how neurologists can assess the status of patients on DMT and decide when it may be necessary to modify treatment in order to optimize outcomes. The CMSWG's recommendations are based on monitoring relapses, neurological progression and MRI activity. These recommendations have yet to be implemented in a prospective, randomized, comparative Phase IV clinical trial.
