E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective for this study is to assess the efficacy of switching to subcutaneous (SC) Tocilizumab (as monotherapy or in combination with MTX or other non-biologic DMARDs) in patients who are currently being treated with have an inadequate response to current non-biologic DMARD therapy or the first anti-TNF biologic agent (as monotherapy or in combination with MTX or other non-biologic DMARDs). Inadequate response to anti-TNF treatment is assessed at Week 24 or after a minimum period of 12 weeks of therapy if permitted by local guidance (either defined by the National Institute for Health and Clinical Excellence (NICE) as a Disease Activity Score 28 (DAS28) improvement of less than 1.2, or patients not achieving a DAS28 of ≤ 3.2 according to a treat-to-target strategy). Efficacy will be measured by DAS28-ESR and Clinical Disease Activity Index (CDAI) at every visit up to Week 52. |
|
E.2.2 | Secondary objectives of the trial |
o To evaluate safety & tolerability of SC Tocilizumab over time (as monotherapy or in combination with MTX or other non-biologic DMARDs) comprising AEs, physical examination, vital signs, clinical laboratory assessments, including immunogenicity, in patients with active RA up to wk 52.
o To assess efficacy of SC TCZ (monotherapy or in combination with MTX or other non-biologic DMARDs) over time using endpoints such as DAS28 ESR, ACR response scores, EULAR response criteria, SDAI or CDAI, TJC/SJC, and patient reported outcomes (PROs) up to wk 52, including onset of action at wk 2.
o Evaluate proportion of patients who achieve low disease activity, defined by DAS28-ESR ≤ 3.2 with SC Tocilizumab (monotherapy or in combination with MTX or other non-biologic DMARDs) at every visit up to wk 52.
o Evaluate the proportion of patients who achieve remission defined by DAS28-ESR < 2.6 with SC TCZ (monotherapy or in combination with DMARDs) at every visit up to wk 52.

Patients must meet the following criteria for study entry:
1. Able and willing to give written informed consent and comply with the requirements of the study protocol.
2. Patients at least 18 years of age.

4. Oral corticosteroids (≤10 mg/day prednisone or equivalent) and nonsteroidal anti- inflammatory drugs (NSAIDs; up to the maximum recommended dose) are permitted if on a stable dose regimen for ≥4 weeks prior to Baseline.
5. Permitted non-biologic DMARDs are allowed if at a stable dose for at least 4 weeks prior to Baseline.
6. Receiving treatment on an outpatient basis, not including Tocilizumab.
7. Females of childbearing potential and males with female partners of childbearing potential may participate in this study only if using a reliable means of contraception (e.g., physical barrier [patient or partner], contraceptive pill or patch, spermicide and barrier, or intrauterine device) during the study. Females of childbearing potential and males with female partners of childbearing potential must use a reliable means of contraception for at least 3 months following the last dose of TCZ.

9.Patients who have an inadequate response to current non-biologic DMARD therapy or the first anti-TNF agent (in monotherapy or in combination with MTX or other non-biologic DMARDs). Inadequate response to anti-TNF treatment is defined as not achieving an adequate response to treatment at 24 weeks or after a minimum period of 12 weeks therapy if permitted by local guidance (timing of assessment according to local clinical practice and no more than 8 weeks post-Week 24) defined by NICE as a DAS28 score improvement of less than 1.2 or patients achieving a 1.2 reduction in DAS28 but not achieving low disease activity (current DAS28 ESR above 3.2) and have not been previously exposed to treatment with tocilizumab. |
