2. Subjects who are receiving 40 mg ADA once weekly must be on ADA 40 mg eow for 8 weeks prior to screening;

3. Subjects with at least a 6 month history of chronic plaque psoriasis;

4. Subjects greater than or equal to 18 years of age;

5. If female, subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile or is of childbearing potential and is practicing birth control;

5. Subject has a history of neurologic symptoms suggestive of central nervous system (CNS) demyelinating disease and/or diagnosis of central demyelinating disease;

6. Subject has evidence of dysplasia or history of malignancy (including lymphoma and leukemia) other than a successfully treated non-metastatic cutaneous squamous cell or basal cell carcinoma or localized carcinoma in situ of the cervix;

7. Subject has a history of listeriosis, histoplasmosis, untreated TB, persistent chronic infections, or recent active infections requiring hospitalization or treatment with intravenous (iv) anti-infectives within 30 days or oral anti-infectives within 14 days prior to the Baseline visit;

8. Subject is known to have immune deficiency, history of human immunodeficiency virus (HIV) or is immunocompromised;

9. Subject currently uses or plans to use anti-retroviral therapy at any time during the study;

10. Female subject who is pregnant or breast-feeding or considering becoming pregnant during the study or for 150 days after the last dose of study medication;

11. Subject has a history of clinically significant drug or alcohol usage in the last year or cannot maintain an alcohol intake of 30 g a day or less throughout the study (one standard drink is defined as 180 mL/6 oz (approx. 10 g) of wine, 360 mL/12 oz (approx. 15 g) of regular beer, or 45 mL/1.5 oz (approx. 10 g) of spirits;

12. Screening clinical laboratory analyses show any of the following abnormal laboratory results:

• Aspartate transaminase (AST) or alanine transaminase (ALT) > 2x the upper limit of normal (ULN);
• Serum total bilirubin > 1.5 mg/dL (> 26 micromol/L), except for subjects with Gilbert's Syndrome;
• Creatinine > 1.5 mg/dL (133 micromol/L) in subjects ≤ 65 years old and > upper limit of normal range in subjects > 65;
• Positive Hepatitis B or C serology indicative of previous or current infection.

13. Subject is considered by the Investigator, for any reason, to be an unsuitable candidate for the study;

14. The following treatments are prohibited for all subjects during the study:

• Phototherapy (ultraviolet A with psoralen [PUVA] within 4 weeks of the Baseline Visit and/or ultraviolet B (UVB) within 2 weeks of the Baseline Visit);
• Other biologic therapies (including any other anti-tumor necrosis factor [TNF]) within 4 weeks of the Baseline Visit;
