6 juli 2017 bijgewerkt door: Hoffmann-La Roche
Tocilizumab Efficacy and Safety in RA Patients After Inadequate Response to DMARDs or Anti-TNF
This open-label, single arm study will evaluate the safety and efficacy of RoActemra/Actemra (tocilizumab) in patients with active, moderate to severe rheumatoid arthritis who have an inadequate response to disease-modifying antirheumatic drugs (DMARDs) or anti-TNF.
Patients will receive RoActemra/Actemra at a dose of 8 mg/kg (max 800 mg) intravenously every 4 weeks for a total of 6 infusions.
Non-biologic DMARD therapy may be continued throughout the study.
Anticipated time on study treatment is 24 weeks.

Disease Activity as Measured by Disease Activity Score 28 (DAS28)
Tijdsspanne: Up to 1 year
|
The DAS28 is a combined index for measuring disease activity in rheumatoid arthritis (RA).
The index includes swollen (range 0-28) and tender (range 0-28) joint counts, acute phase response (erythrocyte sedimentation rate [ESR] in millimeters per hour [mm/hr]), and general health status (participant global assessment of disease activity using visual analog scale [VAS], range 1-100 mm).
DAS28, which uses a 28-joint count, is derived from the original DAS, which includes a 44-swollen joint count.
The DAS28 scale ranges from 0 to 10, where higher scores represent higher disease activity.

Number of Participants Who Achieved Clinically Meaningful Health Assessment Questionnaire Response
Tijdsspanne: Up to 1 year
|
Health Assessment Questionnaire (HAQ) is a self-completed participant questionnaire specific for Rheumatoid Arthritis.
It consists of 20 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip; common daily activities.
Each domain has at least 2 component questions.
There are 4 possible responses for each component 0=without any difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do.
To calculate HAQ, the participant must have a domain score for at least 6 out of 8 domains.
The HAQ is the sum of the scores, divided by the number of domains that have a score (in range 6-8) for a total possible score minimum/maximum 0 (best) to 3 (worst).
A negative change from baseline indicated improvement.
Clinically meaningful HAQ response was defined as an improvement of at least 0.22 units from baseline in the HAQ Disability Index.

Changes in Participant's Fatigue Assessed Using the Mean FACIT-Fatigue Score
Tijdsspanne: Up to 1 year
|
The FACIT-Fatigue score was calculated according to a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function.
Participants scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much).
The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the participants fatigue.
For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participant's response).
The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score).

Change in Fatigue as Measured Using the Fatigue Visual Analog Scale
Tijdsspanne: Up to 1 year
|
The VAS for Fatigue (VAS-F) consists of a 100 mm line, with 0 (No Fatigue) on one end, and 100 (Extreme Fatigue) on the other end, which a participant marks to indicate how much fatigue he or she feels.
The marked point in mm is converted into a numeric value from 0 to 100, where 0=no fatigue and 100=maximum fatigue.
Increasing numbers=increasing fatigue.
