Efficacy, Safety and Tolerability of ACZ885 in Patients With Active Rheumatoid Arthritis
- Registration Number
- NCT00424346
- Lead Sponsor
- Novartis
- Brief Summary
The 12-week core study was designed to evaluate risk-benefit of three subcutaneous dose regimens of ACZ885, added on to stable methotrexate (MTX) therapy (greater than or equal to 7.5 mg/week), compared to placebo in patients with active rheumatoid arthritis (RA). The study investigated the magnitude of effect as well as onset of effect for the different dose regimens.
The primary objective of the extension studies was to assess long-term safety and tolerability of canakinumab (ACZ885) in patients with active RA. CACZ885A2201E1 evaluated this objective in patients who had participated in the core study (CACZ885A2201) and CACZ885A2201E2 did the same in patients who completed the first extension study.

To enhance objectivity, the physician was not aware of the specific patient's global assessment of disease activity when performing their own assessment on that patient. The distance in mm from the left edge of the scale was measured. A negative change from Baseline score indicates improvement in assessment of disease activity.
Least squares means (LSM) were derived from an Analysis of Covariance (ANCOVA) model adjusting for treatment and center with baseline value as a covariate.Change From Baseline in Health Assessment Questionnaire (HAQ) Score Baseline and Weeks 2, 4, 8 and 12 The patient health assessment questionnaire (HAQ) was used to assess the physical ability and functional status of participants as well as quality of life. The disability dimension consists of 20 multiple choice items concerning difficulty in performing eight common activities of daily living; dressing and grooming, arising, eating, walking, reaching, personal hygiene, gripping and activities. Participants choose from four response categories, ranging from 'without any difficulty' (Score=0) to 'unable to do' (Score=3). The overall score is the average of each of the 8 category scores and ranges from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. A negative change from Baseline score indicates improvement in disability status.

Least squares means (LSMs) were derived from an Analysis of Covariance (ANCOVA) model adjusting for treatment and center with baseline DAS28 value as a covariate.Change From Baseline in Erythrocyte Sedimentation Rate Baseline and Weeks 2, 4, 8 and 12 Erythrocyte sedimentation rate (ESR) indirectly measures how much inflammation is in the body. A higher ESR is indicative of increased inflammation. A negative change from Baseline score indicates improvement.
Change From Baseline in Rheumatoid Factor Concentration Baseline and Weeks 4, 8 and 12 Rheumatoid factor (RF) is an autoantibody (antibody directed against an organism's own tissues) that is an indicator of inflammation and rheumatoid arthritis.
Change From Baseline in Short Form 36 Health Survey (SF-36) Baseline and Weeks 2, 4, 8 and 12 The SF-36 measures the impact of disease on overall quality of life and consists of eight subscales (physical function, pain, general and mental health, vitality, social function, physical and emotional health) which can be aggregated to derive a physical-component summary score and a mental-component summary score. Scores for each subscale range from 0 to 10, and the composite scores range from 0 to 100, with higher scores indicating better health. A positive change from Baseline score indicates improvement in quality of life.
Change From Baseline in Functional Assessment of Chronic Illness Therapy- Fatigue (FACIT-F) Baseline and Weeks 2, 4, 8 and 12 The fatigue subscale of the FACIT is a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function. Participants respond to each item on a 5-point Likert-type scale (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; 4 = very much) based on their experience of fatigue during the past 2 weeks. The scale score is computed by summing the item scores, after reversing those items that are worded in the negative direction. FACIT Fatigue subscale scores range from 0 to 52, where higher scores represent less fatigue.
Least squares means (LSMs) were derived from an Analysis of Covariance (ANCOVA) model adjusting for treatment and center with baseline FACIT-F value as a covariate.Number of Distinct Responders According to ACR20, ACR50 and ACR70 Criteria at the End of the Extension Study Baseline and End of Study (up to 124 weeks) To assess differences between the level of clinical response attained and not just whether the patient did or did not achieve a particular level of response, patients were categorized as follows:
