Summary

The purpose of this study was to determine how effective and safe the study drug Olokizumab was in patients with Rheumatoid Arthritis (RA) who had been already receiving, but not fully responding to treatment with an existing medication called a tumour necrosis factor alpha inhibitor The primary objective of this study was to evaluate the efficacy of olokizumab (OKZ) 64 mg administered subcutaneously (SC) once every 2 weeks (q2w) or once every 4 weeks (q4w) relative to placebo in subjects with moderately to severely active rheumatoid arthritis (RA) inadequately controlled by TNF-α inhibitor (TNFi) therapy.
