Exclusion Criteria:
History of any clinically significant cardiac, endocrinologic, pulmonary, neurologic, psychiatric, hepatic, renal, hematologic, immunologic, or other major diseases
* Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study
* Pregnant or lactating female
* History of active Mycobacterium tuberculosis infection (any subspecies) within 3 years prior to the screening visit. Infections that occurred \> 3 years prior to entry must have been effectively treated.
* History of incompletely treated latent Mycobacterium tuberculosis infection (as indicated by a positive Purified Protein Derivative \[PPD\] skin test or in vitro test \[T SPOT®.TB, QuantiFERON Gold®\])
* Clinically significant abnormality on the chest x-ray (CXR) at screening

Nonmedicated emollients \[eg, Eucerin®\] and tar shampoo are also allowed.)

* Use of intra-articular corticosteroids within 28 days prior to randomization
* Use of any investigational medication within 28 days prior to randomization or 5 half-lives if known (whichever is longer)
* Any clinically significant abnormality on 12-lead electrocardiogram (ECG) at screening
* High-risk factor(s) for, or a history of, human immunodeficiency virus (HIV), hepatitis B, or hepatitis C virus infection
