  Purpose

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.

    The physician's global assessment of disease activity was performed using a 100 mm visual analog scale (VAS) ranging from no arthritis activity (0) to maximal arthritis activity (100). 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 [ Time Frame: Baseline and Weeks 2, 4, 8 and 12 ] [ Designated as safety issue: No ]

    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 (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 Short Form 36 Health Survey (SF-36) [ Time Frame: Baseline and Weeks 2, 4, 8 and 12 ] [ Designated as safety issue: No ]
    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) [ Time Frame: Baseline and Weeks 2, 4, 8 and 12 ] [ Designated as safety issue: No ]

    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.

  9. Patients with a history of immunization for Influenza (within past 12 months) and Pneumococcal vaccination (within 4 years) were included. If not already immunized, vaccination was completed when medically indicated (only during flu season for influenza) and such patients were included after approximately a 3 week window post-immunization to allow immunity to develop for vaccine.
  10. Weight ≥45 kg and body mass index (BMI) <34.0
  11. Women of non-child-bearing potential, defined as all women physiologically not capable of becoming pregnant.

Core Study Inclusion criteria At Baseline (Visit 3)

  1. Disease activity criteria of ≥6 out of 28 tender joints and ≥6 out of 28 swollen joints.
  2. One of the following also had to be present:

    1. High-sensitive C-Reactive Protein (hsCRP) concentration ≥10 mg/L
    2. Erythrocyte Sedimentation Rate (ESR) ≥28 mm/1st hr
    3. a. + b. based on screening values.

EXCLUSION

  1. History of hypersensitivity to study drug or to molecules with similar structures.
  2. Any therapy by intra-articular injections (e.g. corticosteroid) required for treatment of acute RA flare within 4 weeks before randomization.
  3. Current use of DMARDs other than MTX. DMARDs included but were not limited to: biologic agents, thiolates (D-penicillamine, thiopronine), sulfasalazine, gold compounds, antimalarials, cyclosporine A, azathioprine, leflunomide, and alkylating agents such as cyclophosphamide.
  4. If a patient had been discontinued from DMARDs, the patient should have been off the agent for at least 4 weeks, except leflunomide which was 8 weeks.
  5. Patients with evidence of active pulmonary disease (e.g. tuberculosis, fungal diseases).
  6. Donation or loss of 400 mL or more of blood within 8 weeks prior to dosing.
  7. Who had a live vaccination within 12 weeks before randomization, or were planning to have one during the study and were not willing/able to postpone until study completion.
  8. a) With bacterial, fungal or viral infections at the time of enrollment, including patients with evidence of human immunodeficiency virus (HIV) infection, hepatitis B and hepatitis C infection.

    b) History of a positive purified protein derivative (PPD) of tuberculin skin test without a follow-up of a negative chest X-ray.

    c) Patients requiring administration of antibiotics against latent tuberculosis, e.g. isoniazide.

  9. Underlying metabolic, hematologic, renal, hepatic, infectious or gastrointestinal conditions which in the opinion of the investigator immunocompromised the patient and/or placed the patient at unacceptable risk for participation in an immunomodulatory therapy. In particular, clinical evidence or history of multiple sclerosis or other demyelinating diseases, or Felty's syndrome.
  10. With significant medical problems, including but not limited to the following: uncontrolled hypertension (≥160/95 mmHg), congestive heart failure, type-I-diabetes(well controlled type-II-diabetes was allowed even when requiring insulin), thyroid disease (unless the patient was taking a stable dose of thyroid hormone for at least 12 weeks before randomization).
  11. Other rheumatic diseases that could confound the evaluation of efficacy, including but not limited to primary fibromyalgia, ankylosing spondylitis, Lyme disease, adult juvenile RA, systemic lupus erythematosus, gout and pseudo gout, vasculitis, psoriatic arthritis, reactive arthritis, primary Sjoegren's Syndrome, and Behcet's Syndrome.
  12. Any medical or psychiatric condition which, in the Investigator's opinion, would preclude the participant from adhering to the protocol or completing the study per protocol.
  13. History of malignancy of any organ system, treated or untreated, within the past 5 years (with the exception of adequately treated basal cell carcinoma or squamous-cell carcinoma of the skin, carcinoma in situ of the cervix, colon polyps with non-invasive malignancy that have been removed).
  14. Use of any investigational drug other than RA therapy and/or devices at the time of randomization, or within 30 days or 5 half- lives of randomization, whichever was longer.
