Criteria

Inclusion Criteria:

• Ambulatory males or females between the ages of 20 and 75 years, inclusive, at time of study entry

• Have active RA defined as at least 6 swollen and at least 6 tender joints based on the 66/68 joint count

• Regular use of MTX for at least 12 weeks, and treatment at a stable dose of 6 to 16 mg/week (2 or 3 times a week) for at least 8 weeks prior to the treatment period. The dose of MTX should remain stable throughout the study, but may be adjusted for safety reasons.

• For participants receiving corticosteroids, they must be on a dose not to exceed 10 mg of prednisone daily (or equivalent) and have been on the same dosing regimen for at least 6 weeks prior to the treatment period

• Have C-Reactive Protein (CRP) measurement > 0.5 milligrams/deciliter (mg/dL) or Erythrocyte Sedimentation Rate (ESR) > 28 millimeters/hour (mm/hr). The CRP and ESR may be repeated once during the screening period at the discretion of the investigator, and the repeat results may be accepted for study eligibility purposes

Exclusion Criteria:

• Use of nonsteroidal anti-inflammatories (NSAIDs) for less than 4 weeks prior to the treatment period. If on NSAIDs, must be on a stable dose of the drug for at least 4 weeks prior to the treatment period and must remain on a stable dose throughout the study

• Received prior treatment with an oral Janus Kinase (JAK) inhibitor regardless of when they received it

• Have a diagnosis of Felty's syndrome

• Evidence of human immunodeficiency virus (HIV) infection and/or positive human HIV antibodies

• Have hepatitis C virus (HCV; positive for anti-hepatitis C antibody with confirmed presence of HCV)

• Positive for hepatitis B surface antigen (HBsAg+), OR negative for hepatitis B surface antigen (HBsAg-), but positive for hepatitis B core antibody (HBcAb+) and/or positive for hepatitis B surface antibody (HBsAb+) with positive Hepatitis B virus (HBV)-deoxyribonucleic acid (DNA) [≥2.1 Log copy/mL by Polymerase Chain Reaction (PCR) method] detected in the serum

• Have a positive result of the QuantiFERON®-tuberculosis (TB) Gold test (QFT-G) or a purified protein derivative (PPD) test

• Have estimated Glomerular Filtration Rate (GFR) from serum creatinine using the Modification of Diet in Renal Disease (MDRD) method of <50 milliliter/minute (mL/min)
