A Study of ARRY-438162 in Patients With Rheumatoid Arthritis

Study Overview
=================
Brief Summary
-----------------
This is a Phase 2 study, involving a 12-week treatment period, designed to evaluate the effectiveness of investigational study drug ARRY-438162 in treating rheumatoid arthritis in patients on stable doses of methotrexate, and to further evaluate the safety of the study drug. Approximately 200 patients from the US, Argentina, Brazil, Hungary, Peru, Poland and Romania will be enrolled in this study.

Eligibility Criteria
-----------------
Key Inclusion Criteria: Diagnosis of rheumatoid arthritis, based on the American College of Rheumatology (ACR) 1987 Revised Criteria, prior to first dose of study drug. Patient has received a stable dose of methotrexate for ≥ 6 weeks prior to first dose of study drug and is willing to continue on this regimen for the duration of the study. Patient has received a stable dose of folate for ≥ 6 weeks and is willing to continue on this regimen for the duration of the study. No prior use of biological agents for the treatment of rheumatoid arthritis. Additional criteria exist. Key Exclusion Criteria: Diagnosis of any other inflammatory or non-inflammatory arthritis that may interfere with disease activity assessments or clinically apparent osteoarthritis which would affect subsequent efficacy measures. A history of severe, progressive, and/or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurological disease or severe systemic involvement with rheumatoid arthritis. Additional criteria exist.

| Disease Activity Score (DAS) Using C-Reactive Protein (DAS28-4[CRP]) | The DAS28-4(CRP) score is a measure of the subject's disease activity. DAS28-4(CRP) is based on the tender joint count (28 joints), swollen joint count (28 joints), patient's global assessment of disease activity and CRP. DAS28 provides a number on a scale (0 to 10) indicating current disease activity. A score above 5.1 means high disease activity and a score below 3.2 indicates low disease activity. | Baseline |
