Immunogenicity of Sarilumab Monotherapy in Patients with Rheumatoid Arthritis Who Were Inadequate Responders or Intolerant to Disease-Modifying Antirheumatic Drugs.

ABSTRACT:

Introduction

This open-label study evaluated the immunogenicity, safety, and efficacy of sarilumab monotherapy in patients with active, moderate-to-severe rheumatoid arthritis (RA) and inadequate response or intolerance to prior conventional synthetic disease-modifying antirheumatic drugs.

Methods

Adults with RA (n = 132) were randomized to receive subcutaneous sarilumab (150 [n = 65] or 200 mg [n = 67]) every 2 weeks (q2w) for 24 weeks. Endpoints included incidence of antidrug antibodies (ADAs) at week 24, safety, and efficacy.

Results

Persistent ADAs occurred in eight patients (12.3%) receiving sarilumab 150 mg q2w, seven of whom (10.8%) had neutralizing antibodies (NAbs), and in four patients (6.1%) receiving sarilumab 200 mg q2w, two of whom (3.0%) had NAbs; all e
