  • Change From Baseline to Week 4 in Synovitis of the Wrist According to Rheumatoid Arthritis Magnetic Resonance Imaging (RAMRIS) Score [ Time Frame: Baseline and Week 4 ]
    Synovitis of the wrist was assessed at three sites including the radioulnar joint (RUJ), the radiocarpal joint (RCJ), and the intercarpal-carpometacarpal joints (IC-CMCJ). Global RAMRIS scores were assigned on a scale of 0 to 3 at each site, where 0 represented normal appearance with no synovial enhancement and each 1-point increase reflected one-third of the presumed maximum volume of enhancing tissue in the synovial compartment. The scores for all three sites were added to give an aggregated score of 0 to 9. Baseline absolute value (AV) and change from Baseline to Week 4 were averaged among all participants, where negative changes indicated improvement in synovitis.
  • Change From Baseline to Week 4 in Synovitis of the Wrist According to Relative Enhancement (RE) Before and After Contrast Injection [ Time Frame: Baseline and Week 4 ]
    RE was calculated as [S0 minus (-) S55] divided by (÷) S0, multiplied by (×) 100 percent (%), where S0 was defined as the signal noise ratio before contrast injection, and S55 was defined as the signal noise ratio 55 seconds after injection. Signal noise ratios were measured as the ratio between the signal in the region of interest and the standard deviation of background noise. Baseline AV and change from Baseline to Week 4 were averaged among all participants, where negative changes indicated improvement in synovitis.
  • Change From Baseline to Week 4 in Synovitis of the Wrist According to Rate of Early Enhancement (REE) Per Second Before and After Contrast Injection [ Time Frame: Baseline and Week 4 ]
    REE per second was calculated as [S55 - S0] ÷ [S0 × 55 seconds] × 100%, where S0 was defined as the signal noise ratio before contrast injection, and S55 was defined as the signal noise ratio 55 seconds after injection. Signal noise ratios were measured as the ratio between the signal in the region of interest and the standard deviation of background noise. Baseline AV and change from Baseline to Week 4 were averaged among all participants, where negative changes indicated improvement in synovitis.

A Study of Tocilizumab in Combination With Disease-Modifying Anti-Rheumatic Drugs (DMARDs) in Participants With Moderate to Severe Active Rheumatoid Arthritis With an Inadequate Response to DMARDs
Open Label, Multicentric Phase IIIb Study to Evaluate the Effect of Tocilizumab in Combination With DMARDs in the Inhibition of Progression of Synovitis, Bone Marrow Edema, and Erosions Evaluated by Dedicated Magnetic Resonance Imaging (MRI) in the Hand of Patients With Rheumatoid Arthritis (RA)
