A Study of the Safety and Efficacy of Golimumab (CNTO 148) in Subjects With Active Rheumatoid Arthritis Previously Treated With Biologic Anti-TNFa Agent(s)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy and safety of golimumab (CNTO 148) in subjects who have active rheumatoid arthritis and have been treated previously with at least 1 dose of a biologic anti-TNFa agent (etanercept, adalimumab or infliximab).

Detailed Description
-----------------
Golimumab is a fully human protein (antibody) which binds to tumor necrosis factor-alpha (TNFa). TNFa is increased in patients with rheumatoid arthritis (RA), and plays a major role in causing the joint pain, swelling and damage from RA. Other marketed drugs that target TNFa (anti-TNFa drugs) have been shown to be effective in reducing the symptoms, signs and joint damage of RA, but have limitations with respect to safety and ease of use. This is a randomized, double-blind, placebo-controlled trial of the efficacy and safety of a new anti-TNFa drug, golimumab, at 2 doses, injected under the skin every 4 weeks in subjects with active RA previously treated with at least 1 dose of a biologic anti-TNFa agent (etanercept, adalimumab or infliximab). Concomitant therapy with methotrexate, sulfasalazine and/or hydroxychloroquine is permitted if the subject has tolerated these medications for at least 12 weeks prior to the first administration of study drug and is on a stable dose for at least 4 weeks prior to the first administration of study agent. The study hypothesis is that golimumab will be a safe and effective treatment for RA in subjects with active RA previously treated with at least one biologic anti-TNFa agent as measured by the American College of Rheumatology (ACR) response criteria, the Disease Activity Score 28 (DAS28) responses and the change from baseline in Health Assessment Questionnaire (HAQ), without causing unacceptable significant adverse effects. The ACR response criteria were designed to assess the level of improvement in the signs and symptoms of RA. The DAS28 responses also measure improvement in the signs and symptoms of RA using the joint examination and laboratory testing. The HAQ is a series of questions that measure a subject's impairment in physical function caused by RA. Patients will receive golimumab 50 mg or 100 mg or placebo injections under the skin every 4 weeks until Week 24. After Week 24, all subjects receive golimumab 50 mg or 100 mg injections, and golimumab continues for all groups every 4 weeks for about 4 and a half more years.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| American College of Rheumatology (ACR) 20 Response at Week 14. | ACR 20 response is an improvement of >= 20% from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments ( patient's assessment of pain visual analog scale (VAS), patient's global assessment of disease activity VAS scale, Physician's global assessment of disease activity VAS scale, Health Assessment Questionnaire and C-reactive protein) | Week 14 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| American College of Rheumatology (ACR) 50 Response at Week 14 | Number of patients who achieved an ACR 50 response at Week (Wk) 14. ACR 50 response is an improvement of >= 50% from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments ( patient's assessment of pain visual analog scale (VAS), patient's global assessemnt of disease activity VAS scale, Physician's global assessment of disease activity VAS scale, Health Assessment Questionnaire and C-reactive protein). | Week 14 | 
| Disease Activity Index Score 28 (DAS 28) (Using C-reactive Protein) Response at Week 14 | DAS 28 using C-reactive protein (CRP) is an index to measure disease activity in participants with rheumatoid arthritis which combines tender joint count (28 joints), swollen joint count (28 joints), CRP value, and participant's global assessment of disease activity (using a Visual Analog Scale of 0 to 100 mm). The DAS 28 score ranges from 0 (best) to 10 (worst). | Week 14 | 
| American College of Rheumatology (ACR) 20 at Week 24 | Number of patients who achieved ACR 20 response at Week (Wk) 24. ACR 20 response is an improvement of >= 20% from baseline in both the tender and swollen joint count and in at least 3 of the 5 assessments ( patient's assessment of pain visual analog scale (VAS), patient's global assessemnt of disease activity VAS scale, Physician's global assessment of disease activity VAS scale,HAQ and CRP) | From Baseline to Week 24 | 
| Health Assessment Questionnaire (HAQ) Score at Week 24 | Improvement from baseline in HAQ score at Week 24. This 20-question instrument assesses the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area are scored from 0, indicating no difficulty, to 3, indicating inability to perform a task in that area based on the worst score from the questions that pertain to that task. The HAQ score is determined by the average of the 8 scores; HAQ ranges from 0 to 3. | From Baseline to Week 24 |
