The purpose of this study is to evaluate the safety and efficacy of ASP015K in moderate to
severe rheumatoid arthritis (RA) subjects


Subjects will take ASP015K or matching placebo orally with food for 12 weeks after
randomization. Potential subjects who have previously used disease-modifying antirheumatic
drugs (DMARDs) and/or biologic agents may be eligible to participate after completing a
washout period. Subjects who complete the 12-week dosing period in this study may be
eligible to participate in a long-term, open-label Extension Study.

28 mm/hr

- Subject meets the ACR 1991 Revised Criteria for Global Functional Status in RA Class
I, II or III at Screening and Baseline

- Use of non-steroidal anti-inflammatory drugs [NSAIDs], cyclooxygenase-2 (COX-2)

- History of any malignancy, except for successfully treated basal or squamous cell
carcinoma of the skin or in-situ carcinoma of the cervix.

- Does not meet specified washout criteria for the following RA medications: gold,
azathioprine, minocycline, penicillamine, etanercept, certolizumab, adalimumab,
golimumab, infliximab, cyclophosphamide, and leflunomide

- Previous intolerance to Janus kinase (JAK) inhibitors

- Receipt of intra-articular or parenteral corticosteroid within 28 days prior to the

- Receipt of any investigational agent within 30 days or 5 half-lives, whichever is
longer, prior to first dose of study drug

- Receipt of medications that are CYP3A substrates with narrow therapeutic range within
14 days prior to first dose of study drug

- History of heart failure, defined as New York Heart Association (NYHA) grade 3 or
greater

- History of long QT syndrome or prolonged QT interval

- Any ongoing severe, progressive, or uncontrolled renal, hepatic, hematological,
gastrointestinal, metabolic, endocrine, pulmonary, cardiac, neurological, or
