Evaluation of the Efficacy and Safety of Two Dosing Regimens of Olokizumab (OKZ), Compared to Placebo and Adalimumab, in Subjects With Rheumatoid Arthritis (RA) Who Are Taking Methotrexate But Have Active Disease

Not Recruiting

Trial ID: NCT02760407


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 methotrexate (MTX). The primary objective of this study was to evaluate the efficacy of 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 RA inadequately controlled by MTX therapy. The secondary objective was to evaluate the efficacy of OKZ relative to adalimumab in subjects with moderately to severely active RA inadequately controlled by MTX therapy.

Inclusion Criteria:

   - Subjects willing and able to sign informed consent

   - Subjects must have a diagnosis of adult onset RA classified by ACR/EULAR 2010 revised
   classification criteria for RA for at least 12 weeks prior to Screening. (If the
   subject was diagnosed according to ACR 1987 criteria previously, the Investigator may
   classify the subject per ACR 2010 retrospectively, using available source data)

   - Inadequate response to treatment with oral, SC, or intramuscular MTX (defined as a
   subject with at least 12 weeks of exposure prior to Screening and with either absence
   of any documented clinically significant response, or documented initial clinical
   response with subsequent loss of that response or partial response) for at least 12
   weeks prior to Screening at a dose of 15 to 25 mg/week (or ≥10 mg/week if intolerant
   to higher doses). The dose and route of administering MTX had to have been stable for
   at least 6 weeks prior to Screening. A lower dose of MTX (≥7.5 mg/week) was permitted
   for subjects enrolled in the Republic of Korea, consistent with local clinical

   - Subjects must be willing to take folic acid or equivalent throughout the study.

Exclusion Criteria:

   - Diagnosis of any other inflammatory arthritis or systemic rheumatic disease (eg, gout,
   psoriatic or reactive arthritis, Crohn's disease, Lyme disease, juvenile idiopathic
   arthritis, or systemic lupus erythematosus). However, subjects could have secondary

   agents (e.g., CAMPATH, anti CD4, anti CD5, anti CD3, and anti CD19)

   change in dosage within 2 weeks prior to baseline

   - Prior documented history of no response to hydroxychloroquine and sulfasalazine

   - Prior use of cDMARDs (other than MTX) within the following windows prior to baseline
   (cDMARDs should not be discontinued to facilitate a subject's participation in the
   study, but should instead have been previously discontinued as part of a subject's
   medical management of RA):

      1. 4 weeks for sulfasalazine, azathioprine, cyclosporine, hydroxychloroquine,
      chloroquine, gold, penicillamine, minocycline, or doxycycline
