A Randomized, Double-Blind, Double-Dummy Study Assessing The Safety and Tolerability of Sarilumab and Tocilizumab In Patients With Rheumatoid Arthritis Who Are Inadequate Responders to or Intolerant of TNF Antagonists
- Diagnosis of RA, according to the American College of Rheumatology (ACR)/European
League against Rheumatism (EULAR) 2010 Rheumatoid Arthritis Classification Criteria
with ≥ 3 months disease duration.
- ACR Class I-III functional status, based on the 1991 revised criteria.
- Moderate-to-severely active RA.
- Anti-TNF therapy failures, defined as patients with an inadequate clinical response
defined by the investigator, after being treated for at least 3 consecutive months,
and/or intolerance to at least 1 anti-TNF, resulting in their discontinuation.
Anti-TNFs may include, but are not limited to, etanercept, infliximab, adalimumab,
golimumab and/or certolizumab pegol.
- Continuous treatment with one or a combination of non-biologic disease modifying
antirheumatic drugs (DMARDs) for at least 12 consecutive weeks prior to screening and
on a stable dose(s) for at least 6 consecutive weeks prior to screening:
- Methotrexate - 10 to 25 mg/wk orally or intra muscular (or per local labeling
requirements if the dose range differs)
- Leflunomide - 10 to 20 mg orally daily
- Sulfasalazine (SSZ) - 1000 to 3000 mg orally daily
- Hydroxychloroquine (HCQ) - 200 to 400 mg orally daily
- Patients <18 years of age.
- Use of parenteral corticosteroids or intra-articular corticosteroids within 4 weeks
prior to screening.
- Use of oral corticosteroids in a dose higher than prednisone 10 mg or equivalent per
day, or a change in dosage within 4 weeks prior to screening.
- 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 systemic RA, including but not limited to vasculitis, pulmonary fibrosis,
and/or Felty's syndrome.
- Participation in any clinical research study that evaluated an investigational drug
or therapy within 5 half-lives or 60 days of the Screening Visit, whichever is
- Patients with active tuberculosis or latent tuberculosis infection.
- Prior or current history of interstitial lung disease.
- Prior treatment with anti-IL-6 or anti-IL-6R therapies, including but not limited to
tocilizumab or sarilumab.
- Treatment with anti-TNF agents, as follows:
- Etanercept: within 28 days prior to randomization
- Infliximab, adalimumab, golimumab, certolizumab pegol: within 42 days prior to
- Treatment with RA-directed biologic agents with non- TNF-α antagonist mechanisms
without adequate washout as follows:
- Anakinra: within 28 days prior to randomization
- Abatacept: within 42 days prior to randomization
- Rituximab or other cell depleting agent: Within 6 months prior to randomization
or until total lymphocyte count and CD 19+ lymphocyte count are normalized, or
whichever is longer.
- Prior treatment with a janus kinase (JAK) inhibitor (eg, tofacitinib).
- Patients with a history of invasive opportunistic infection.
- Prior or current history of malignancy, including lymphoproliferative diseases, 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
- Prior or current history of other significant concomitant illness(es) that, according
to Investigator's judgment, would adversely affect the patient's participation in the
