A Study Assessing the Safety and Efficacy of Sarilumab Added to Non-MTX DMARDs or as Monotherapy in Japanese Patients With Active Rheumatoid Arthritis (SARIL-RA-HARUKA)

A Randomized, Double-blind, Multicenter Study Evaluating the Safety and Efficacy of Sarilumab Added to Non-MTX DMARDs or as Monotherapy in Japanese Patients With Active Rheumatoid Arthritis

Primary Objective:

To document the long-term safety of sarilumab added to non-methotrexate (non-MTX) disease-modifying antirheumatic drugs (DMARDs) or as monotherapy.

Secondary Objective:

To document the long term efficacy of sarilumab added to non-MTX DMARDs or as monotherapy.

Total study duration was up to 62 weeks: Up to 4-week screening period, 52-week treatment period, and 6-week post-treatment follow-up period.

Inclusion criteria:

Diagnosis of rheumatoid arthritis (RA), according to the American College of Rheumatology/The European League Against Rheumatism (ACR/EULAR) 2010 Rheumatoid Arthritis Classification Criteria with >=3 months disease duration.

Moderately to severely active RA defined as:

• At least 4 of 68 tender joints and 4 of 66 swollen joints at screening visit.
• High sensitivity C-Reactive Protein (hs-CRP) >=4 mg/L or Erythrocyte Sedimentation Rate (ESR) >=28 mm/hr at screening visit.

For the combination stratum:

Participants who had continuous treatment with non-biologic DMARDs other than MTX for at least 12 weeks prior to the randomization and on a stable dose for a minimum of 6 weeks prior to screening.

For the monotherapy stratum:

Participants who per investigator judgment were any of inappropriate, intolerant or inadequate to MTX treatment.

Exclusion criteria:

Participants <20 years of age. Prior treatment with tumor necrosis factor (TNF) antagonists or any other RA-directed biologic agents without the appropriate off-drug period prior to screening.

Prior treatment with anti-interleukin-6 (anti-IL-6) or anti-interleukin-6 receptor (IL-6R) antagonist therapies, including but not limited to tocilizumab or sarilumab.
