Beschrijving
Inclusion Criteria
Patients must have rheumatoid arthritis. Patients will be included in the trial based on the following criteria:
- Patient must meet 1987 American College of Rheumatology (ACR) criteria,
- Age > 18 years of age,
- Baseline DAS28/ESR>4.4,
Stable concomitant DMARDs for more than 1 month (methotrexate, leflunomide, plaquenil, sulfasalazine, or no DMARDs). However, if the patient is not on DMARD, history of DMARD use required.
- If not on DMARD (and the patient satisfies the above statement), the patient can opt for monotherapy with tocilizumab or combination therapy OR
- If on biologic monotherapy, can opt for monotherapy with tocilizumab or DMARD combination therapy (ie. patients cannot be on biologic with TCZ)
6) Power Doppler score of >10 at screening.
General Medical Concerns:
- Normal organ function, except if abnormal due to the disease under investigation
- Men and women of reproductive potential must agree to use an acceptable method of birth control during treatment and for six months after completion of treatment.
- Subject has provided written informed consent.
Exclusion Criteria
A patient will be excluded if the answer to any of the following statements is "yes".
General:

Laboratory Exclusion criteria (at screening):
- Serum creatinine > 1.6 mg/dL (141 µmol/L) in female patients and > 1.9 mg/dL (168 µmol/L) in male patients. Patients with serum creatinine values exceeding limits may be eligible for the study if their estimated glomerular filtration rates (GFR) are >30.

Baseline to Month 3 Change in Total Power Doppler Synovitis Score of 34 Joints (Range 0 - 102)
Tijdsspanne: Baseline, 3 Month
|
34 joints will be evaluated using a 0 to 3 point scale for each joint. Power Doppler synovitis score is the sum of all the joint scores. Change scores are calculated by subtracting Baseline minus 3 Month Power Doppler scores. This scale is called the Power Doppler Synovitis Score (PDUS). It ranges from 0 to 102. Scores of 0 indicate the least amount of inflammation of the joint while scores of 3 indicate the most amount of inflammation. Therefore, a higher value of the total score for PDUS represents more severe disease level. |

Baseline to Month 6 Change in Total Power Doppler Synovitis Score of 34 Joints (Range 0 - 102)
Tijdsspanne: Baseline, 6 Month

34 joints will be evaluated using a 0 to 3 point scale for each joint. Power Doppler synovitis score is the sum of all the joint scores. Change scores are calculated by subtracting Baseline minus 6 Month Power Doppler scores. This scale is called the Power Doppler Synovitis Score (PDUS). It ranges from 0 to 102. Scores of 0 indicate the least amount of inflammation of the joint while scores of 3 indicate the most amount of inflammation.

Baseline to Month 3 Change in Total B-mode Synovial Hypertrophy Score of 34 Joints
Tijdsspanne: Baseline, 3 Month
|
34 joints will be evaluated using a 0 to 3 point scale for each joint. Synovial hypertrophy score is the sum of all the joint scores. Change scores are calculated by subtracting Baseline minus 3 Month Synovial Hypertrophy Scores. This scale is called the Grey Scale Synovial Hypertrophy Score (GSUS). Please note that B-mode is the same as GSUS. It ranges from 0 to 102. Scores of 0 indicate the least amount of inflammation of the joint while scores of 3 indicate the most amount of inflammation. Therefore, a higher value of the total score for GSUS represents more severe disease level. |

Baseline to Month 3 Change in DAS28/ESR
Tijdsspanne: Baseline, 3 month
|
28 joints will be evaluated for Tender Joint Count (TJC) and Swollen Joint Count (SJC) as well as patient and physician global values assessed at the time of each visit, finally the ESR lab value will be included in the total calculation. Change scores are calculated by subtracting Baseline minus 3 Month Disease Activity Score (DAS) scores. The scale being used is called the Disease Activity Score for 28 Joints (DAS28) using the Erythrocyte Sedimentation Rate (ESR) in the calculation rather than the C Reactive Protein (CRP). The scale ranges from 0 to 9.4. Values of DAS28 below 2.6 imply remission, below 3.2 imply low disease activity and greater than 5.1 implies active disease. |

Baseline to Month 3 Change in CDAI
Tijdsspanne: Baseline, 3 month
|
28 joints will be evaluated for TJC and SJC as well as patient and physician global values assessed at the time of each visit. Change scores are calculated by subtracting Baseline minus 3 Month CDAI scores. The scale being used is called the Clinical Disease Activity Index (CDAI) and has a range of 0 to 76. Values of CDAI below 2.8 imply remission, below 10 imply low disease activity, below 22 imply moderate disease activity, and above 22 implies high disease activity. |
