OBJECTIVE: The introduction of oral disease-modifying drugs (DMDs) in addition to the available, injectable, ones for Relapsing-Remitting Multiple Sclerosis (RRMS) could be expected to improve medication persistence due to a greater acceptability of the route of administration. Aim of the study was to compare the proportion of patients discontinuing injectable DMDs (interferon beta 1a/1b, pegylated interferon, glatiramer acetate) with those discontinuing oral DMDs (dimethylfumarate and teriflunomide) during an observation period of at least 12 months. Secondary aims were to compare the time to discontinuation and the reasons for discontinuation between the two groups and to explore the demographic and clinical factors associated with DMD discontinuation. METHODS: In this prospective, multi-center, real-life observational study, patients commencing any first-line DMD between January 1st 2015 and July 31st 2016 were enrolled and followed-up for at least twelve months or until the drug was discontinued. RESULTS: Of the 520 included patients, 262 (49.6%) started an injectable, and 258 (50.4%) an oral DMD. There was no difference in the proportion of patients on oral (nr = 62, 24%) or on injectable (nr = 60, 23%) DMDs discontinuing treatment, the most frequent reason being adverse events/side-effects. Higher baseline EDSS scores and younger age increased the odds of treatment withdrawal. Time to treatment discontinuation was not different between the two groups and was not influenced by the initiated DMD (oral versus injectable), even after adjustment for baseline differences. CONCLUSION: The sole route of administration (i.e. oral versus injectable) was not a significant predictor of persistence with first-line DMDs in RRMS.

Abstract

OBJECTIVE: The introduction of oral disease-modifying drugs (DMDs) in addition to the available, injectable, ones for Relapsing-Remitting Multiple Sclerosis (RRMS) could be expected to improve medication persistence due to a greater acceptability of the route of administration. Aim of the study was to compare the proportion of patients discontinuing injectable DMDs (interferon beta 1a/1b, pegylated interferon, glatiramer acetate) with those discontinuing oral DMDs (dimethylfumarate and teriflunomide) during an observation period of at least 12 months. Secondary aims were to compare the time to discontinuation and the reasons for discontinuation between the two groups and to explore the demographic and clinical factors associated with DMD discontinuation. METHODS: In this prospective, multi-center, real-life observational study, patients commencing any first-line DMD between January 1st 2015 and July 31st 2016 were enrolled and followed-up for at least twelve months or until the drug was discontinued. RESULTS: Of the 520 included patients, 262 (49.6%) started an injectable, and 258 (50.4%) an oral DMD. There was no difference in the proportion of patients on oral (nr = 62, 24%) or on injectable (nr = 60, 23%) DMDs discontinuing treatment, the most frequent reason being adverse events/side-effects. Higher baseline EDSS scores and younger age increased the odds of treatment withdrawal. Time to treatment discontinuation was not different between the two groups and was not influenced by the initiated DMD (oral versus injectable), even after adjustment for baseline differences. CONCLUSION: The sole route of administration (i.e. oral versus injectable) was not a significant predictor of persistence with first-line DMDs in RRMS.
