Study Description
Brief Summary:

Primary Objective:

To evaluate the immunogenicity of sarilumab administered as monotherapy.

Secondary Objectives:

  • To evaluate the other safety aspects of sarilumab administered as monotherapy.
  • To assess the exposure of sarilumab administered as monotherapy.

Condition or disease Intervention/treatment Phase
Rheumatoid Arthritis Drug: sarilumab SAR153191 (REGN88) Phase 3

Detailed Description:
Total study duration was up to 34 weeks: Up to 4-week screening period, 24-week open-label treatment phase, 6-week post-treatment observation. After completion of the treatment phase of this study, participants were eligible to enter a long term safety study (LTS11210 - SARIL-RA-EXTEND) for continuous treatment with sarilumab (SAR153191 [REGN88]).

Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants With Incidence of Antidrug Antibodies (ADA) [ Time Frame: From Baseline to Week 30 [End of study (EOS)] ]
    ADA to sarilumab and anti-sarilumab neutralizing antibodies in serum samples were determined using a validated electrochemiluminescence immunoassay method. Percentage of participants with positive ADA during treatment emergent adverse event (TEAE) period (time from first dose of investigational medicinal product [IMP] to last dose of IMP + 60 days) was determined. Persistent ADA Response: treatment-emergent ADA detected at 2 or more consecutive sampling time points during the TEAE period, where the first and last ADA positive samples were separated by a period of at least 16 weeks or if the last measured sample was positive. ADA samples were collected prior to IMP administration at Week 0 (baseline), Week 2, 4, 12, 24 and 30.


Secondary Outcome Measures :
  1. Serum Sarilumab Concentration [ Time Frame: Pre-dose at Week 0 (Baseline), 2, 4, 12, 16, 20, 24 and 30 ]
    Trough Concentration (Ctrough).

Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  • Diagnosis of rheumatoid arthritis (RA) ≥ 3 months.
  • Moderately to severely active rheumatoid arthritis.
  • Participants who per investigator judgment were incomplete responders to at least 12 weeks of an adequate dose of continuous treatment with or who were intolerant of one or a combination of non-biologic disease modifying anti-rheumatic drugs (DMARDs).

Exclusion criteria:

  • Participants < 18 years of age.
  • 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 prednisone > 10 mg or equivalent per day, or change in dosage within 4 weeks prior to randomization.
  • New treatment with or dose-adjustment of on-going nonsteroidal anti-inflammatory drug (NSAIDs) or cyclooxygenase-2 (COX-2) inhibitors within 4 weeks prior to randomization, except for the use of low-dose acetylsalicylic acid for cardiovascular diseases.
  • Use of parenteral glucocorticoids or intra-articular glucocorticoids injection within 4 weeks prior to randomization.
  • Prior treatment with a Janus kinase (JAK) inhibitor (tofacitinib).
  • New treatment or dose-adjustment to on-going medication for dyslipidemia, such as statin, within 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 dose of study drug administration, whichever is longer.
  • Participants with a history of malignancy other than adequately-treated carcinoma in-situ of the cervix, non-metastatic squamous cell or basal cell carcinoma of the skin, within 5 years prior to the randomization visit. Non-malignant lymphoproliferative disorders are also excluded.
  • Participants with active tuberculosis or untreated latent tuberculosis infection.
  • Pregnant or breast feeding women.
