4. Candidate for phototherapy or systemic therapy
5. Previous failure, inadequate response, intolerance, or contraindication to at least 1 conventional anti-psoriatic systemic therapy (eg, methotrexate, cyclosporine, psoralen plus ultra-violet light [PUVA])
6. For women (except those at least 2 years postmenopausal or surgically sterile): a negative serum pregnancy test during screening and a negative urine pregnancy test at baseline
7. Signed Institutional Review Board/Ethics Committee (IRB/IEC)-approved informed consent and able to complete study procedures
8. No known history of latent or active TB. Subject must meet any 1 of the following 3 criteria:
• Subject has a negative test for tuberculosis during screening, defined as either:
o Negative purified protein derivative (PPD; < 5 mm of induration at 48 to 72 hours after test is placed) OR
o Negative Quantiferon®/T-spot test
• Subjects with a positive PPD and a history of Bacillus Calmette-Guérin vaccination are allowed with a negative Quantiferon®/T-spot®
• Subjects with a positive PPD test (without a history of Bacillus Calmette-Guérin [BCG] vaccination) or subjects with a positive or indeterminate Quantiferon®/T-spot test are allowed if they have all of the following:
o No symptoms per tuberculosis worksheet provided by the sponsor, Amgen
o Documented history of adequate prophylaxis initiation prior to receiving investigational product in accordance with local recommendations
o No known exposure to a case of active TB after most recent prophylaxis
o No evidence of active TB on chest radiograph within 3 months prior to the first dose of investigational product

Exclusion Criteria

Skin disease related conditions
1. Erythrodermic psoriasis (PsO), pustular PsO, guttate PsO, medication induced PsO, or other skin conditions at the time of the screening visit (eg, eczema) that would interfere with evaluations of the effect of investigational product on PsO
Other medical conditions
2. Subject has a planned surgical intervention during the duration of the study
3. Subject has an active infection or history of infections as follows:
a. Any active infection for which systemic anti-infectives were used within 28 days prior to randomization
b. A serious infection, defined as requiring hospitalization or intravenous antiinfectives within 8 weeks prior to randomization
c. Recurrent or chronic infections or other active infection that, in the opinion of the Investigator, might cause this study to be detrimental to the subject
4. Known history of human immunodeficiency virus (HIV)
5. Hepatitis B surface antigen (HbsAg) or HCV antibody positivity at screening
6. Uncontrolled, clinically significant systemic disease such as uncontrolled diabetes mellitus, cardiovascular disease, renal disease, liver disease, or hypertension
7. Known malignancy within the previous 5 years (except treated and considered cured cutaneous squamous or basal cell carcinoma, in situ cervical cancer, OR in situ breast ductal carcinoma)
8. Active neurological disease such as multiple sclerosis, Guillain-Barre syndrome, optic neuritis, transverse myelitis or history of neurologic symptoms suggestive of central nervous system demyelinating disease
9. Moderate to severe heart failure (New York Heart Associate [NYHA] class III/IV)
10. Known hypersensitivity to the investigational product or to any of the excipients
11. Any concurrent medical condition that, in the opinion of the Investigator, could cause this study to be detrimental to the subject Laboratory abnormalities
12. Laboratory abnormalities at screening, including any of the following:
a. Hemoglobin < 9 g/dL
b. Platelet count < 100,000/mm3
c. White blood cell count (WBC) < 3,000 cells/mm3
d. Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) = 2.0 × the upper limit of normal (ULN)
e. Creatinine clearance < 50 mL/min (Cockcroft-Gault formula)
f. Any other laboratory abnormality, which, in the opinion of the Investigator, will prevent the subject from completing the study or will interfere with the interpretation of the study results
