E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the efficacy of clazakizumab versus placebo on a background of methotrexate as
assessed by change from baseline in DAS28-CRP at 12 weeks |
|
E.2.2 | Secondary objectives of the trial |
1) Assess the efficacy of clazakizumab on a background of methotrexate in reducing signs and symptoms of rheumatoid arthritis by measures such as ACR rates, remission rates, and DAS28-CRP < 2.6, over 12 weeks of treatment.
2) Assess the efficacy of clazakizumab on a background of methotrexate in improving physical function as determined by change from baseline in HAQ-DI at 12 weeks of treatment.
3) Assess the safety of clazakizumab on a background of methotrexate by assessment of Adverse Events (AEs) and laboratory parameters.
4) Characterize the pharmacokinetics, immunogenicity, pharmacodynamics and biomarker responses of different clazakizumab doses on a background of methotrexate. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Diagnosis of active Rheumatoid Arthritis (RA) by standard criteria (American Rheumatism association (ARA) [1987] or American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) [2010]) at least 16 weeks prior to screening
• ACR global functional status class of 1 to 3
• Documented evidence of inadequate response approved tumor necrosis factor (TNF) inhibitors.
• All subjects must have been receiving treatment with a minimum dose of 15 mg per week of Methotrexate for at least 12 weeks and at a stable dose for 28 days prior to screening. A dose as low as 10 mg Methotrexate is permitted if 15 mg could not be reached, due to toxicity. Additional treatment with Hydroxychloroquine or Chloroquine is permitted, if it is at a dose approved for the treatment of RA and the dose has been stable for at least 28 days prior to screening
• Minimum of 6 swollen and 6 tender joints on a 66/68 joint count at screening and at baseline (Day 1)
• Elevated High-sensitivity (hs) CRP |
|
E.4 | Principal exclusion criteria |
• Active serious infection
• History of or active TB
• Elevated LFTs
|
|
