Improved cognitive outcomes in patients with relapsing-remitting multiple sclerosis treated with daclizumab beta: Results from the DECIDE study.
Ontology highlight
ABSTRACT: BACKGROUND:Cognitive impairment is common in multiple sclerosis (MS), with cognitive processing speed being the most frequently affected domain. OBJECTIVE:Examine the effects of daclizumab beta versus intramuscular (IM) interferon (IFN) beta-1a on cognitive processing speed as assessed by Symbol Digit Modalities Test (SDMT). METHODS:In DECIDE, patients with relapsing-remitting multiple sclerosis (RRMS) (age: 18-55?years; Expanded Disability Status Scale (EDSS) score 0-5.0) were randomized to daclizumab beta ( n?=?919) or IM IFN beta-1a ( n?=?922) for 96-144?weeks. SDMT was administered at baseline and at 24-week intervals. RESULTS:At week 96, significantly greater mean improvement from baseline in SDMT was observed with daclizumab beta versus IM IFN beta-1a ( p?=?0.0274). Significantly more patients treated with daclizumab beta showed clinically meaningful improvement in SDMT (increase from baseline of ?3 points ( p?=?0.0153) or ?4 points ( p?=?0.0366)), and significantly fewer patients showed clinically meaningful worsening (decrease from baseline of ?3 points ( p?=?0.0103)). Odds representing risk of worsening versus stability or improvement on SDMT were significantly smaller for daclizumab beta ( p?=?0.0088 (3-point threshold); p?=?0.0267 (4-point threshold)). In patients completing 144?weeks of treatment, the effects of daclizumab beta were generally sustained. CONCLUSION:These results provide evidence for a benefit of daclizumab beta versus IM IFN beta-1a on cognitive processing speed in RRMS.
