Evaluating efficacy and safety of ocrelizumab biosimilar (Xacrel) compared to the originator (Ocrevus) in relapsing multiple sclerosis: a phase III, randomized, equivalency, clinical trial.

ABSTRACT: Multiple sclerosis is an inflammatory demyelinating disease and represents a global health concern. Ocrelizumab, a humanized IgG monoclonal antibody, selectively targets CD20 on B cells and CD20-expressing T cells. This study aimed to compare the efficacy and safety of the biosimilar ocrelizumab candidate (Xacrel) to the originator product (Ocrevus) in Relapsing Multiple Sclerosis (RMS) patients. In this randomized trial, patients received either Xacrel or Ocrevus for 96 weeks. The primary endpoint was the equivalency of the medications in reducing the annualized relapse rate (ARR) at week 48. The secondary endpoints included time to the onset of disability progression confirmed at 12 and 24 weeks, the proportion of relapse-free patients, magnetic resonance imaging (MRI) evaluations, safet
