Abstract
BACKGROUND: In the DISCOMS (DISCOntinuation of disease-modifying therapies (DMTs) in multiple sclerosis (MS)) randomized clinical trial, we could not demonstrate that discontinuing MS DMTs in older, stable adults was not inferior to continuing DMTs. Relapses were rare in both groups, and most new disease activity was one to two new brain magnetic resonance imaging (MRI) lesions unassociated with clinical changes.
OBJECTIVE/AIMS: Describe results of the DISCOMS extension study.
METHODS: Among 10/19 of the original sites, we enrolled patients who completed DISCOMS; did not reach the primary endpoint during the original trial; and retained original randomized assignment. Participants completed one study visit and brain MRI at least 30 months after original enrollment in DISCOMS. Primary endpoint was time from entry into the primary study to relapse or new brain MRI activity.
RESULTS: Mean (SD) total follow-up was 40 (11.7) months. There were no relapses, and new brain MRI lesions (1/30 continuer, 2/44 discontinuers) were uncommon during the extension. Time from primary trial entry to disease event was significantly shorter for subjects in the discontinue group (
CONCLUSIONS: From entry into DISCOMS extension study, time to new MS activity remained shorter in discontinuers, but relapses were absent and new brain MRI lesions were rare.
