E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of treatment with SC TCZ monotherapy and/or in combination with MTX or other non biologic DMARDs with regard to achievement of clinical remission as measured by Disease Activity Score 28 (DAS28) <2.6 at the end of 24 weeks of treatment in patients with active rheumatoid arthritis (RA) |
|
E.2.2 | Secondary objectives of the trial |
To assess the efficacy of treatment with SC TCZ monotherapy and/or in combination with MTX or other non-biol. DMARDs over time at wk 24 & 52, includ. onset of action at wk 2.To evaluate the ability to maintain the optimal therapeutic target (Remission or LDA) of SC TCZ monotherapy, following MTX/other non-biol.(nb) DMARDs discontinuation from SC TCZ in combination with MTX/other nb DMARDs from wk 24 to 52.To evaluate the proportions of patients who will flare while on SC TCZ monotherapy and will necessitate add-on of MTX/other NB DMARDs to maintain the optimal therapeutic target (Remission or LDA), achieved between wk 24 – 52.To evaluate the safety and tolerability of SC TCZ as monotherapy and/or in combination with MTX or other NB DMARDs comprising AEs, physical examination, vital signs, and clinical lab.assessments, includ. immunogenicity, in patients with active RA at wk 24 & 52.Proportion of patients and reasons for corticosteroid dose reductions and/or discontinuation over time |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
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.
3. Patients with a diagnosis of active RA according to the revised (1987) ACR criteria or EULAR/ACR (2010) criteria.
4. Oral corticosteroids (≤10 mg/day prednisone or equivalent) and 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 TCZ.
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 must use a reliable means of contraception for at least 3 month following the last dose of TCZ.
8. If female of childbearing potential, the patient must have a negative pregnancy test at the Screening and Baseline visits.
9. The target population for this study is adult men or women with active Rheumatoid Arthritis ,DAS28(ESR) >3.2, early RA of less than 6 month duration or established RA of more than 6 month duration , either naïve to MTX and /or other non biologic DMARD’s treatment, or having inadequate response (inefficacy/intolerance) to previous non biologic DMARDs ( MTX-IR, DMARD-IR) and/or having inadequate response (inefficacy/ intolerance) to previous biologic DMARDs (including Tumor necrosis factor-TNFiIR or Abatacept- when this was assigned as first line biologic-Abatacept IR IR). Patients who have experienced inadequate responses (inefficacy/intolerance) to previous biologics DMARDs could participate in this study with or without going through a biologic wash-out period. The time between the last dose of TNF inhibitor or Abatacept and the inclusion in the study could be between 1 and 8 weeks depending on the approved dosing interval as reported in the SmPC and according to the physician’s judgment.
