Randomized, Double-Blind, Placebo-Controlled, Multiple-Dose Studies to Assess the Safety and Efficacy of Elezanumab when Added to Standard of Care in Relapsing and Progressive Forms of Multiple Sclerosis.

ABSTRACT:

Objective

Elezanumab is a monoclonal antibody that binds repulsive guidance molecule a (RGMa), an inhibitor of central nervous system regeneration after inflammation or injury. The aim was to assess the safety and efficacy of elezanumab in relapsing and progressive forms of multiple sclerosis (MS).

Methods

RADIUS-R and RADIUS-P were phase 2 trials in relapsing (RADIUS-R) or progressive (RADIUS-P) MS. Participants were randomized to intravenous elezanumab 400mg, 1800mg, or placebo every 4 weeks through week 48. The primary endpoint was the mean Overall Response Score (ORS).

Results

In RADIUS-R, 208 participants received elezanumab 400mg (n = 69), elezanumab 1800mg (n = 69), or placebo (n = 70). In RADIUS-P, 123 participants received elezanumab 400mg (n = 40), elezanuma
