INTRODUCTION: Multiple sclerosis is a chronic neurological disease with numerous disease-modifying treatments available, including dimethyl fumarate (DMF), a first-line therapy for relapsing-remitting multiple sclerosis. Although rates of discontinuation of DMF are generally low in clinical trials, non-adherence to treatment is associated with poorer clinical outcomes. Assessing real-world adherence and predictive factors is critical to be able to improve clinical outcomes for patients. This study evaluated adherence to DMF over 24 months in a cohort of patients treated in a Portuguese healthcare centre.
PATIENTS AND METHODS: A prospective, non-interventional, single-centre study with 24 months' follow-up was conducted. The study included adult patients with relapsing-remitting multiple sclerosis treated with DMF in routine clinical practice. Adherence to DMF was calculated and patients were considered to have adhered if the value was above 80%. Clinical and socio-demographic variables were compared between groups.
RESULTS: Of the 80 patients included, 74% were women, with a mean age of 39 years and a mean age of 32 years at diagnosis. Twenty-six patients had not received any previous treatment. Adherence varied between 93, 82 and 87.5% at 6, 12 and 24 months, respectively. No differences were found between patients who had not received any prior treatment and those who had been treated.
CONCLUSION: This real-world analysis showed significant adherence to DMF treatment by Portuguese patients over a period of two years. However, these results must be interpreted in the light of the substantial changes in outpatient consultations and the various periodic restrictions due to the COVID-19 pandemic, which had an important effect on patient follow-up and data collection.
