Sumario:INTRODUCTION: The main objective of this study was to examine discontinuation rates associated with delayed-release dimethyl fumarate (DMF) when used for the treatment of relapsing multiple sclerosis (MS) in a real-world, clinical practice setting. METHODS: Data were collected retrospectively from charts of adult patients with relapsing–remitting MS treated at a single large institution in Australia, who completed at least 6 months of continuous therapy, either with DMF or another MS medication administered following DMF discontinuation. The primary endpoint was overall discontinuation rate. Secondary endpoints included discontinuation rate 6 months after initiation of DMF therapy; incidence of adverse events, particularly gastrointestinal events; discontinuation rate because of adverse events; and use of concomitant medications by patients during administration of DMF. RESULTS: A total of 100 patients initially prescribed DMF between October 1, 2013 and June 30, 2014 were included in the analysis. The mean age of the patients was 43 years and 80% were female. The overall discontinuation rate was 13%, with 9% discontinuing because of gastrointestinal tolerability issues, within the first 6 months. Dose changes as a result of adverse events occurred in 15% of patients, and none of the adverse events reported were serious. Only one patient discontinued owing to lack of efficacy. CONCLUSION: This study, conducted shortly after the approval of DMF in Australia when first-hand clinical experience was still limited, demonstrated that DMF has an acceptable tolerability profile in the real-world setting that is similar to that demonstrated in clinical trials.
