Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 217
Healthy volunteers: no

Brief summary:
Primary Objective:

To collect real-use data of the sarilumab auto-injector device (AID) used by rheumatoid arthritis (RA) participants.

Secondary Objective:

To compare the pharmacokinetic (PK) exposure of sarilumab administered by AID versus prefilled syringes (PFS).

Detailed description:
Total study duration up to 74 weeks: screening up to 4 weeks, AID assessment phase of 12 weeks, extension phase of 52 weeks and post-treatment follow-up of 6 weeks.

For participants not entering the extension phase, total study duration up to 22 weeks (screening, AID assessment phase and follow-up).

Arms:
arm 1: Sarilumab 150 mg subcutaneous (SC) injection every 2 weeks (q2w) administered by AID with one or a combination of non-biologic disease-modifying anti-rheumatic drug (DMARD) (hydroxychloroquine, methotrexate, sulfasalazine and/or Leflunomide, except for simultaneous combination use of leflunomide and methotrexate) in AID assessment phase for 12 weeks. Participants who completed 12 weeks AID assessment phase entered in open-label extension phase and received sarilumab 150 mg SC injection q2w administered by PFS with one or a combination of non-biologic DMARD for 52 weeks. arm 2: Sarilumab 150 mg SC injection q2w administered by PFS with one or a combination of non-biologic DMARD (hydroxychloroquine, methotrexate, sulfasalazine and/or Leflunomide, except for simultaneous combination use of leflunomide and methotrexate) in AID assessment phase for 12 weeks. Participants who completed 12 weeks AID assessment phase entered in open-label extension phase and received sarilumab 150 mg SC injection q2w administered by PFS with one or a combination of non-biologic DMARD for 52 weeks. arm 3: Sarilumab 200 mg SC injection q2w administered by AID with one or a combination of non-biologic DMARD (hydroxychloroquine, methotrexate, sulfasalazine and/or Leflunomide, except for simultaneous combination use of leflunomide and methotrexate) in AID assessment phase for 12 weeks. Participants who completed 12 weeks AID assessment phase entered in open-label extension phase and received sarilumab 150 mg SC injection q2w administered by PFS with one or a combination of non-biologic DMARD for 52 weeks. arm 4: Sarilumab 200 mg SC injection q2w administered by PFS with one or a combination of non-biologic DMARD (hydroxychloroquine, methotrexate, sulfasalazine and/or Leflunomide, except for simultaneous combination use of leflunomide and methotrexate) in AID assessment phase for 12 weeks. Participants who completed 12 weeks AID assessment phase entered in open-label extension phase and received sarilumab 150 mg SC injection q2w administered by PFS with one or a combination of non-biologic DMARD for 52 weeks.
