E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of treatment with tocilizumab (TCZ) 8 mg/kg intravenously (iv) (every 4 weeks) versus adalimumab (ADA) 40 mg subcutaneously (sc) (every 2 weeks), both in combination with methotrexate (MTX), 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 moderate to severe active rheumatoid arthritis (RA) who have had an inadequate efficacy response to treatment with only one tumor necrosis factor (TNF) inhibitor (other than ADA). |
|
E.2.2 | Secondary objectives of the trial |
To compare the effects of TCZ and ADA by assessing:
• Efficacy parameters at week 24 by using American College of Rheumatology (ACR) criteria, European League Against Rheumatism (EULAR) criteria, low disease activity scores, patient-reported health assessments (Health Assessment Questionnaire [HAQ], Functional Assessment of Chronic Illness Therapy- Fatigue questionnaire
[FACIT-Fatigue Scale], Short Form-36 [SF-36], Routine Assessment of Patient Index Data [RAPID3]).
• Change of haemoglobin levels at week 24 vs baseline.
• Safety throughout the study. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Adult patients, >/= 18 years of age
- Rheumatoid arthritis of >/= 6 months duration (according to ACR criteria)
- Inadequate response due to inefficacy of treatment (3-15 months) with only one approved TNF-agent other than adalimumab. Depending on the TNF-inhibitor, last dose of TNF-inhibitor should have been 1 to 8 weeks before randomization to the study
- On methotrexate treatment for >/=12 weeks immediately prior to baseline, with stable dose (10-25 mg/week) for the last 8 weeks
- Disease Activity Score (DAS28) >3.2 at baseline
- Oral corticosteroids (</=10 mg/day prednisone or equivalent) and non-steroidal anti-inflammatory drugs (NSAIDs) are permitted if the dose has been stable for >/=6 weeks prior to baseline |
|
E.4 | Principal exclusion criteria |
- Major surgery (including joint surgery) within 8 weeks prior to screening or planned surgery within 6 months following randomization
- Rheumatic autoimmune disease other than rheumatoid arthritis
- Prior history of or current inflammatory joint disease other than rheumatoid arthritis
- Functional class IV (ACR criteria)
- History of severe allergic reaction to human, humanized or murine monoclonal antibodies
- Known active current or history of recurrent infection (including TB)
- Primary or secondary immunodeficiency (history of or currently active)
- Body weight >150 kg
- Previous treatment with any cell-depleting therapies
- Previous treatment with tocilizumab
- Intra-articular or parenteral corticosteroids within 6 weeks prior to baseline |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The end of the study will occur when the last patient, last visit occurs (LPLV). The LPLV is either the date of the last patient visit of the last patient to complete the study, or the date at which the last data point from the last patient, which is required for statistical analysis (i.e., key safety and efficacy results for decision making), is received, whichever is the later date. |
