A Study of Effectiveness and Safety of CNTO 136 in Patients With Active Rheumatoid Arthritis Despite Methotrexate Therapy
- Conditions
- Arthritis, Rheumatoid
- Interventions
- Registration Number
- NCT00718718
- Lead Sponsor
- Centocor, Inc.
- Brief Summary
The purpose of this study is to evaluate the effectiveness and safety of subcutaneous (under the skin) administration of anti-interleukin-6 monoclonal antibody (CNTO 136) in reducing signs and symptoms of participants with active rheumatoid arthritis (RA) with methotrexate (MTX) therapy.
- Detailed Description
This is a multicenter, double-blind (neither physician nor participants knows the treatment that the participant receives), randomized (study medication is assigned by chance), placebo-controlled (an inactive substance is compared with a medication to test whether the medication has a real effect in a clinical study) study. This study will be conducted in 2 parts (Part A and Part B). Each part consists of 3 phases: screening (approximately 1 month prior to the start of study medication), treatment phase (Part A: 22 weeks and Part B: 24 weeks), and follow-up phase (approximately 4 months after the last administration of study medication). In Part A, participants will be randomly assigned to 2 groups to receive CNTO 136 100 mg and placebo for 22 weeks. All participants in Part A, will be crossed over at Week 12 from placebo to CNTO 136 (for Group 1) and from CNTO 136 to placebo (for Group 2). In Part B, participants will be randomly assigned to 5 groups to receive placebo and/or 1 of 3 doses of CNTO 136 (100mg, 50mg or 25mg) for 24 weeks. Participants in Part B, Group 1 will be crossed over at Week 12 from placebo to CNTO 136. All participants should be maintained on a stable dose of MTX for at least 6 weeks prior to the start of study medication through Week 24. Safety will be evaluated by the assessment of adverse events, vital signs, clinical findings, 12-lead electrocardiogram, and clinical laboratory tests which will be monitored throughout the study. The total duration of study participation for a participant will be approximately 42 weeks.

- Primary Outcome Measures
Name Time Method Percentage of Participants With an American College of Rheumatology (ACR) 50 Response at Week 12 (Part B) Week 12 An American College of Rheumatology (ACR) 50 response is defined as greater than or equal to (\>=) 50 percent (%) improvement in both tender joint count (68 joints) and swollen joint count (66 joints) and \>= 50% improvement in 3 of the following 5 assessments: participant's assessment of pain using Visual Analogue Scale (Score) VAS (0-10 scale, 0=no pain and 10=worst possible pain), participant's global assessment of disease activity by using VAS (the scale ranges from 0 to 10, \[0 = very well to 10 = very poor\]), physician's global assessment of disease activity using VAS (the scale ranges from 0 to 10, \[0=no arthritis activity to 10=extremely active arthritis\]), participant's assessment of physical function as measured by Health Assessment Questionnaire-Disability Index (HAQ-DI, the scale ranges from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area), and serum C-reactive protein (CRP).
- Secondary Outcome Measures
Name Time Method Change From Baseline in Disease Activity Index Score 28 (DAS28) Based on C-reactive Protein (CRP) at Week 12 (Part A and Part B) Baseline, Week 12 The DAS28 based on C-Reactive Protein (CRP) is a statistically derived index combining tender joints (28 joints), swollen joints (28 joints), CRP and patient's global assessment of disease activity. The set of 28 joint count is based on evaluation of the shoulder, elbow, wrist, metacarpophalangeal (MCP) MCP1 to MCP5, proximal interphalangeal (PIP) PIP1 to PIP5 joints of both the upper right extremity and the upper left extremity as well as the knee joints of lower right and lower left extremities. The values are 0=best to 10=worst. A negative change from baseline in DAS28 (CRP) (that is, a decrease from baseline) indicates improvement from baseline.
Serum Sirukumab Concentrations Through Week 38 (Part A) Week 0, Day 2, Day 5, Day 8, Day 11, Week 2, Week 4, Week 8, Week 10, Week 10 Day 4, Week 10 Day 7, Week 12, Week 14, Week 18, Week 22, Week 24, and Week 38 Sirukumab Concentrations in serum were measured.
Percent Improvement From Baseline in Serum C-Reactive Protein (CRP) At Week 2 (Part A and Part B) Baseline, Week 2 Serum CRP is a marker of systemic inflammation. A negative change from baseline in CRP represents improvement.
Serum Sirukumab Concentrations Through Week 38 (Part B) Week 0, Day 5, Day 8, Day 11, Week 2, Week 4, Week 8, Week 12, Week 16, Week 20, Week 24, Week 24 Day4, Week 24 Day7, Week 26, Week 28, Week 30, Week 34 and Week 38 Sirukumab Concentrations in serum were measured.
Percentage of Participants With American College of Rheumatology (ACR) 50 Response at Week 12 (Part A) Week 12 An ACR 50 response is defined as \>= 50% improvement in both tender joint count (68 joints) and swollen joint count (66 joints) and \>= 50% improvement in 3 of the following 5 assessments: Participant's assessment of pain using VAS (0-10 scale, 0=no pain and 10=worst possible pain), Participant's global assessment of disease activity by using VAS (the scale ranges from 0 to 10, \[0 = very well to 10 = very poor\]), Physician's global assessment of disease activity using VAS (the scale ranges from 0 to 10, \[0=no arthritis activity to 10=extremely active arthritis\]), Participant's assessment of physical function as measured by HAQ-DI (the scale ranges from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area), and Serum CRP.
