Oral or intravenous methylprednisolone (≥500 mg/day for 5 days) is recommended for multiple sclerosis (MS) relapses. Nonetheless, the optimal dose remains uncertain. We compared clinical and radiological effectiveness, safety and quality of life (QoL) of oral methylprednisolone [1250 mg/day (standard high dose)] versus 625 mg/day (lesser high dose), both for 3 days] in MS relapses.
A total of 49 patients with moderate to severe MS relapse within the previous 15 days were randomized in a pilot, double‐blind, multicentre, non‐inferiority trial (ClinicalTrial.gov, NCT01986998). The primary endpoint was non‐inferiority of the lesser high dose by Expanded Disability Status Scale (EDSS) score improvement on day 30 (non‐inferiority margin, 1 point). The secondary endpoints were EDSS score change on days 7 and 90, changes in T1 gadolinium‐enhanced and new/enlarged T2 lesions on days 7 and 30, and safety and QoL results.
The primary outcome was achieved [mean (95% confidence interval) EDSS score difference, −0.26 (−0.7 to 0.18) at 30 days (P = 0.246)]. The standard high dose yielded a superior EDSS score improvement on day 7 (P = 0.028). No differences were observed in EDSS score on day 90 (P = 0.352) or in the number of T1 gadolinium‐enhanced or new/enlarged T2 lesions on day 7 (P = 0.401, 0.347) or day 30 (P = 0.349, 0.529). Safety and QoL were good at both doses.
A lesser high‐dose oral methylprednisolone regimen may not be inferior to the standard high dose in terms of clinical and radiological response.
