Outcomes of older patients with multiple sclerosis treated with interferon beta-1a or peginterferon beta-1a in MS PATHS.

ABSTRACT:

Background

The peak prevalence of multiple sclerosis (MS) is shifting to older patients. Using real-world data, we describe outcomes among older (≥60 years) and younger patients treated with interferon beta-1a or no disease-modifying therapy (no-DMT).

Methods

Assessments over 24 months included annualized relapse rates (ARRs), patient-reported disability outcomes, and MS Performance Test (MSPT) outcomes.

Results

The study included 767 interferon-treated and 2783 no-DMT patients. ARR over 24 months was lower for the older and younger interferon-treated patients than the no-DMT patients. Mean change in Patient-Determined Disease Steps (PDDS) from baseline-24 months was -0.13 (1.08) in older interferon-treated patients vs 0.20 (1.30) in older no-DMT patients.
