• Meet Classification Criteria for Psoriatic Arthritis (CASPAR)

• Have a history consistent with PsA ≥ 6 months at Screening

• Have active PsA defined as ≥ 3 swollen joints (from a 66 swollen joint count [SJC]) and ≥ 3 tender joints (from a 68 tender joint count [TJC]) at Screening and Day 1; these may or may not be the same joints at Screening and Day 1

• Must have a documented history or active signs of at least one of the following at Screening

• Plaque psoriasis

• Nail changes attributed to psoriasis

• Have had inadequate response (lack of efficacy after ≥ 12 week duration of therapy) or intolerance to at least one and not more than 3 biologic DMARDs (bioDMARD) administered for the treatment of PsA or psoriasis, as per local guidelines / standard of care

• Prior to the first dose of study drug on Day 1, treatment with bioDMARD(s) should have been discontinued

Exclusion Criteria:

• Prior exposure to a janus kinase (JAK) inhibitor > 2 doses

• Any active / recent infection

• Any chronic and / or uncontrolled medical condition that would put the subject at increased risk during study participation or circumstances which may make a subject unlikely or unable to complete or comply with study procedures and requirements, per investigator judgement

• Any moderately to severely active musculoskeletal or skin disorder other than PsA or plaque psoriasis that would interfere with assessment of study parameters, as per judgement of investigator

NOTE: Prior history of reactive arthritis or axial spondyloarthritis is permitted if there is documentation of change in diagnosis to PsA or additional diagnosis of PsA

• Any history of an inflammatory arthropathy with onset before age of 16 years old

• Active autoimmune disease that would interfere with assessment of study parameters or increase risk to the subject by participating in the study, (e.g. uveitis, inflammatory bowel disease, uncontrolled thyroiditis, systemic vasculitis, transverse myelitis), per judgement of investigator

• Pregnancy or nursing females

• Active drug or alcohol abuse, as per judgement of investigator

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
