• If taking non-steroidal anti-inflammatory drugs (NSAIDs), subjects must have been on stable doses for ≥ 2 weeks prior to randomization
• If taking oral corticosteroids, daily doses must be ≤ 10 mg/day of prednisone or equivalent and stable for ≥ 4 weeks before randomization
• Subject is willing to participate to the study and has signed the informed consent prior to undergoing any screening procedures
• Women of childbearing potential (WOCBP) and men must agree to use at least two acceptable methods to avoid pregnancy for the entire study period and until 60 days (for women) and 90 days (for men) after the last dose of BMS-817399. WOCBP must have a negative urine pregnancy test at screening, randomization and at scheduled visits throughout the study

Exclusion Criteria:

• Subjects who are bed- or wheelchair-bound
• Subjects with other autoimmune diseases or arthritis syndromes
• Women who are pregnant, breastfeeding or with a positive pregnancy test at screening or prior to randomization
• Subjects who have any condition that could impact upon the absorption of study drug (i.e., gastric stapling, duodenal surgery, malabsorption syndrome)
• Subjects with a history of, or a concurrent severe, progressive, or uncontrolled disease (other than RA) that in the opinion of the investigator might place the subject at unacceptable risk for participation in this study
• Subjects who have present or previous (last 5 years) malignancies, except history of cured squamous or basal skin cell carcinoma or cured breast or cervical cancer
• Subjects at risk for tuberculosis (TB) or with evidence of TB clinical history, chest X rays or tuberculin skin test
• Subjects with evidence of active or latent bacterial or viral infections (including human immunodeficiency virus); Positive blood screen for hepatitis B surface antigen or hepatitis C antibody
• Subjects with any serious bacterial infection within the last 2 months, unless treated and resolved with antibiotics
