Observational Study of Tocilizumab in Participants With Rheumatoid Arthritis in Australia
10. června 2016 aktualizováno: Hoffmann-La Roche
A Multi-National, Multi-Center Non-Interventional Study in Rheumatoid Arthritis (RA) Patients Treated With Tocilizumab (ACT-UP)
This multi-center, observational study will evaluate the treatment patterns in clinical practice, efficacy and safety of tocilizumab in participants with rheumatoid arthritis (RA) who have had an inadequate response (or were intolerant to) treatment with non-biological disease-modifying anti-rheumatic drugs (DMARDs) or with one biological agent.
Data will be collected from each eligible participant initiated on tocilizumab treatment by their treating physician according to approved label for 6 months from start of treatment.

The HAQ-DI is a questionnaire that measures functional status (disability) and health-related quality of life.
It measures the participant's ability to perform everyday tasks.
The index consists of 20 questions regarding the function of the upper and lower extremities.
These questions are summarized in 8 categories: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and common activities over past week.
Each question is evaluated according to the degree of severity on a 4-point scale.
Total score for HAQ-DI is the average of all questions and ranges from 0 = without any difficulty to 3 = unable to do.

|
TJC was determined by examining 28 and 68 joints and identifying the joints that were painful under pressure or to passive motion.
Tenderness was recorded on the joint assessment form at baseline, no tenderness = 0, tenderness = 1.
SJC was determined by examining 28 and 66 joints and identifying when swelling was present.
Swelling was recorded on the joint assessment form at baseline, no swelling = 0, swelling =1.

Erythrocyte Sedimentation Rate (ESR) at Baseline
Časové okno: Baseline
|
ESR is a laboratory test that provides a non-specific measure of inflammation.
The test assesses the rate at which red blood cells fall in a test tube.
Normal range is 0-30 millimeters per hour (mm/hr).
A decrease in the level indicates reduction in inflammation and therefore improvement.

Disease Activity Score Based on 28 Joint Count (DAS28) Score by Visit
Časové okno: Baseline, Month 3, Month 6
|
The DAS28 score is a measurement of RA activity on a 0 to 10 scale, with higher scores representing higher disease activity, and calculated as DAS28 = 0.56 x √TJC28 + 0.28 x √SJC28 + 0.70 x natural logarithm (ln) (CRP + 1) + 0.014 x PGH + 0.96, where TJC28 = tender joint count on 28 units, SJC28 = swollen joint count on 28 units, CRP = serum concentration of c-reactive protein (after converting units to mg/dL), PGH = patient global assessment of disease activity, which was measured on a 100 mm VAS, where 0 = managing very well and 100 = managing very poorly.
A score of less than 2.6 represents clinical remission, a score of greater than or equal to 2.6 and less than or equal to 3.2 represents low disease activity, a score of greater than 3.2 and less than or equal to 5.1 represents moderate disease activity, and a score of greater than 5.1 represents high (or severe) disease.

Časové okno: Month 3 and Month 6
|
Clinical response was assessed according to EULAR criteria that classified the participant according to individual changes in DAS28 score as good, moderate, or no response.
The DAS28 score is a measurement of RA activity on a 0 to 10 scale, with higher scores represent higher disease activity, and calculated as DAS28 = 0.56 x √TJC28 + 0.28 x √SJC28 + 0.36 x ln(CRP + 1) + 0.014 x PGH + 0.96, where TJC28 = tender joint count on 28 units, SJC28 = swollen joint count on 28 units, CRP = serum concentration of c-reactive protein (after converting units to mg/dL), PGH = patient's global assessment of disease activity, which was measured on a 100 mm VAS, where 0 = managing very well and 100 = managing very poorly.
Good responders experienced a change from baseline of greater than 1.2 with a DAS28 score less than or equal to 3.2.

Clinical Disease Activity Index (CDAI) Score by Visit
Časové okno: Baseline, Month 3, Month 6
|
The CDAI is a combined index for measuring disease activity in RA and calculated as CDAI = TJC28 + SJC28 + PGH (in centimeters) + PhGH (in centimeters), where TJC28 = tender joint count on 28 units, SJC28 = swollen joint count on 28 units, PGH = patient's global assessment of disease activity, assessed on a 100 mm VAS, where 0 = managing very well and 100 = managing very poorly, and PhGH = physician global assessment of disease activity, assessed on a 100 mm VAS, where 0 = no arthritis activity and 100 = extremely active arthritis; with a total score ranged from 0-76.
Higher scores indicate greater disease activity.
CDAI score of less than or equal to 2.8 represents clinical remission, score of less than or equal to 10.0 represents low disease activity, score of less than or equal to 22.0 represents moderate disease activity, and score of greater than 22.0 represents high (or severe) disease.

Simplified Disease Activity Index (SDAI) Score by Visit
Časové okno: Baseline, Month 3, Month 6

The SDAI is a combined index for measuring disease activity in RA and calculated as SDAI = TJC28 + SJC28 + PGH (in centimeters) + PhGH (in centimeters) + CRP (in mg/dL), where TJC28 = tender joint count on 28 units, SJC28 = swollen joint count on 28 units, PGH = patient's global assessment of disease activity, assessed on a 100 mm VAS, where 0 = managing very well and 100 = managing very poorly, PhGH = physician global assessment of disease activity, assessed on a 100 mm VAS, where 0 = no arthritis activity and 100 = extremely active arthritis, CRP = serum concentration of c-reactive protein; with a total SDAI score ranged from 0-86.
Higher scores indicate greater disease activity.
SDAI scores of less than or equal to 3.3 represents clinical remission, less than or equal to 11.0 represents low disease activity, less than or equal to 26.0 represents moderate disease activity, and greater than 26.0 represents high (or severe) disease.
