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

Completed · Phase 3 · Has a placebo group

Conditions studied: Rheumatoid Arthritis

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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 practice.
• Subjects must be willing to take folic acid or equivalent throughout the study.
• Subjects must have moderately to severely active RA disease as defined by all of the following:
• ≥6 tender joints (68 joint count) at Screening and baseline; and
• ≥6 swollen joints (66 joint count) at Screening and baseline; and
• CRP above the normal range (ULN) at Screening based on the central laboratory results.

You may not qualify if…

• 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 Sjogren's syndrome or hypothyroidism.
• Subjects who are Steinbrocker class IV functional capacity (incapacitated, largely or wholly bed-ridden or confined to a wheelchair, with little or no self-care)
• Prior exposure to any licensed or investigational compound directly or indirectly targeting IL 6 or IL 6R (including tofacitinib or other Janus kinases and spleen tyrosine kinase [SYK] inhibitors)
• Prior treatment with cell depleting therapies including anti CD20 or investigational agents (e.g., CAMPATH, anti CD4, anti CD5, anti CD3, and anti CD19)
• Prior use of bDMARDs
• Use of parenteral and/or intra-articular glucocorticoids within 4 weeks prior to baseline
• Use of oral glucocorticoids greater than 10 mg/day prednisone (or equivalent) or 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):
• 4 weeks for sulfasalazine, azathioprine, cyclosporine, hydroxychloroquine, chloroquine, gold, penicillamine, minocycline, or doxycycline
• 12 weeks for leflunomide unless the subject has completed the following elimination procedure at least 4 weeks prior to baseline: Cholestyramine at a dosage of 8 grams 3 times daily for at least 24 hours, or activated charcoal at a dosage of 50 grams 4 times daily for at least 24 hours
• 24 weeks for cyclophosphamide
• Vaccination with live vaccines in the 6 weeks prior to baseline or planned vaccination with live vaccines during the study
• Participation in any other investigational drug study within 30 days or 5 times the terminal half-life of the investigational drug, whichever is longer, prior to baseline
• Other treatments for RA (e.g., Prosorba Device/Column) within 6 months prior to baseline
• Use of intra-articular hyaluronic acid injections within 4 weeks prior to baseline
• Use of non-steroidal anti-inflammatory drugs (NSAIDs) on unstable dose or switching of NSAIDs within 2 weeks prior to baseline
• Previous participation in this study (randomized) or another study of OKZ
• Subjects with concurrent acute or chronic viral hepatitis B or C infection as detected by blood tests at Screening(e.g., positive for hepatitis B surface antigen [HBsAg], total hepatitis B core antibody [anti-HBc], or hepatitis C virus antibody [HCV Ab]). Subjects who are are positive for hepatitis B surface antibodies (anti-HBs), but negative for HBsAg and anti-HBc, will be eligible
• Subjects with human immunodeficiency virus (HIV) infection
• Subjects with:
• Suspected or confirmed current active TB disease or a history of active TB disease
• Close contact (i.e., sharing the same household or other enclosed environment, such as a social gathering place, workplace, or facility, for extended periods during the day) with an individual with active TB within 1.5 years prior to Screening
• Concurrent malignancy or a history of malignancy within the last 5 years (with the exception of successfully treated carcinoma of the cervix in situ and successfully treated basal cell carcinoma and squamous cell carcinoma not less than 1 year prior to Screening [and no more than 3 excised skin cancers within the last 5 years prior to Screening])
• Subjects with any infection requiring oral antibiotic or antiviral therapy in the 2 weeks prior to Screening or at baseline, injectable anti-infective therapy in the last 4 weeks prior to baseline, or serious or recurrent infection with history of hospitalization in the 6 months prior to baseline
