First received: August 18, 2009
Last updated: November 1, 2016
Last verified: November 2016
This open-label randomized 2arm study will investigate the pharmacokinetics, pharmacodynamics, efficacy and safety of subcutaneously administered tocilizumab in patients with rheumatoid arthritis who have shown an inadequate response to methotrexate. Patients will be randomized to receive tocilizumab 162 mg sc either weekly or every other week, in combination with methotrexate, for 12 weeks. Assessments will be made at regular intervals during treatment and on the 3 weeks of follow-up.Target sample size is < 50 individuals.

Primary Outcome Measures:
  • Pharmacokinetics of TCZ after QW or Q2W sc administration [ Time Frame: multiple sampling after 1st and last dose, weeks 1 and 12, at bi-weekly intervals during treatment and twice on follow-up ]
  • Pharmacodynamic responses of CRP [ Time Frame: sampling in weeks 1 and 2 and at weekly or bi-weekly intervals throughout treatment ]
  • Safety and tolerability, including injection site reaction [ Time Frame: laboratory assessments every 2nd week on treatment and after 3 weeks follow-up, injection site evaluation after 1st, 2nd and last injection. ]

Secondary Outcome Measures:
  • Efficacy according to ACR and DAS-EULAR parameters [ Time Frame: assessments on day 1 of weeks 1, 4, 8 and 12 ]
  • PD responses of IL-6, sIL-6R and anti TCZ antibody [ Time Frame: multiple sampling after 1st and last dose, weeks 1 and 12, at bi-weekly intervals during treatment and twice on follow-up ]
