A Study of RoActemra/Actemra (Tocilizumab) in Patients With Active Rheumatoid Arthritis Who Have an Inadequate Response to DMARDs (REMISSION)

8 juli 2014 uppdaterad av: Hoffmann-La Roche

A Single Arm, Open Label Study to Assess the Safety, Tolerability and Efficacy of Tocilizumab in Active Rheumatoid Arthritis Patients With Inadequate Response to the DMARDs (REMISSION Study)

This open label, single arm study will assess the safety and efficacy of RoActemra/Actemra (tocilizumab) in patients with moderate to severe active rheumatoid arthritis who have an inadequate response to disease-modifying antirheumatic drugs (DMARDs). Patients will receive RoActemra/Actemra at a dose of 8 mg/kg intravenously every 4 weeks for 24 weeks (6 infusions).

The participant's assessment of their current level of pain was displayed on a 100-mm horizontal VAS. The left-hand extreme (0 mm) of the line was described as "no pain" and the right-hand extreme of the line (100 mm) was described as "unbearable pain". The change in participant's perception of pain was determined as the difference in values from baseline at each visit.

C-Reactive Protein (CRP)
Tidsram: Baseline, Weeks 4, 8, 12, 16, 20, and 24
CRP is an acute phase inflammatory marker. Levels of CRP increase with inflammation. The change in CRP was determined as the difference in values from baseline and at each visit.

Erythrocyte Sedimentation Rate (ESR)
Tidsram: Baseline, Weeks 4, 8, 12, 16, 20, and 24
