Past history of, or current, autoimmune or inflammatory systemic or localized joint disease(s) other than RA

History of juvenile idiopathic arthritis or arthritis onset prior to age 16

Severe active systemic RA, including but not limited to vasculitis, pulmonary fibrosis, and/or Felty's syndrome.

Treatment with anti-TNF agents, as follows:

Within 28 days prior to the baseline visit - etanercept

Within 42 days prior to the baseline visit - infliximab, adalimumab, golimumab, certolizumab pegol

Treatment with previous RA-directed biologic agents with other than TNF antagonist mechanisms:

Within 28 days prior to the randomization (baseline) visit - anakinra Within 42 days prior to the randomization (baseline) visit - abatacept

Within 6 months prior to the randomization (baseline) visit - any cell depleting agents including but not limited to rituximab without a normal lymphocyte and cluster of differentiation (CD) 19+ lymphocyte count

Treatment with any DMARD other than those allowed per protocol and limited to the maximum specified dosage within 12 weeks prior to baseline

Treatment with prednisone \>10 mg or equivalent per day, or change in dosage within 4 weeks prior to baseline visit

Any parenteral or intra-articular glucocorticoid injection within 4 weeks prior to baseline

Prior treatment with anti-interleukin (IL) -6 or IL-6 receptor antagonist therapies, including tocilizumab or sarilumab, participation in a prior study of sarilumab, irrespective of treatment arm

Prior treatment with a Janus kinase inhibitor (such as tofacitinib)

New treatment or dose-adjustment to ongoing medication for dyslipidemia within 6 weeks prior to randomization, ie, stable dose for at least 6 weeks prior to randomization

Participation in any clinical research study evaluating another investigational drug or therapy within 5 half-lives or 60 days of first investigational medicinal product (IMP) administration, whichever was longer

History of alcohol or drug abuse within 5 years prior to the screening visit

Participants with a history of malignancy other than adequately-treated carcinoma in-situ of the cervix, nonmetastatic squamous cell or basal cell carcinoma of the skin, within 5 years prior to the randomization (baseline) visit. Nonmalignant lymphoproliferative disorders were also excluded

Participants with active tuberculosis or latent tuberculosis infection
