Title: A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study Comparing the Efficacy and Safety of ABT-874 to Etanercept and Placebo in Subjects With Moderate to Severe Chronic Plaque Psoriasis
Brief Summary: Compare the efficacy of ABT-874 versus etanercept in subjects with moderate to severe plaque psoriasis


Options:
A: Inclusion Criteria:

* Understand and voluntarily sign an informed consent form
* ≥18 years of age at the time of signing the informed consent form
* Able to adhere to the study visit schedule and other protocol requirements.
* Diagnosis of chronic, stable plaque psoriasis at least 6 months prior to screening as defined by:

  1. PASI (Psoriasis Area and Severity Index) score ≥ 12
  2. Body Surface Area (BSA) ≥ 10%
* Candidate for photo/systemic therapy
* In good health as judged by the investigator, based on medical history, physical examination, 12-lead electrocardiogram (ECG), serum chemistry, hematology, immunology, and urinalysis
* Meet all laboratory criteria as defined per protocol
* Females of childbearing potential (FCBP) must have a negative urine pregnancy test at screening (Visit 1). In addition, sexually active FCBP must agree to use TWO of the following adequate forms of contraception methods. A FCBP must agree to have pregnancy tests every 4 weeks while on study medication
* Males (including those who have had a vasectomy) must agree to use barrier contraception (latex condoms) when engaging in reproductive sexual activity with FCBP while on study medication and for 84 days after taking the last dose of study medication

Exclusion Criteria:

* History of clinically significant disease (as determined by the investigator)
* Pregnant or breastfeeding
* History of active mycobacterial infection within 3 years
* History of Human Immunodeficiency Virus (HIV) infection
* Congenital and acquired immunodeficiencies
* Hepatitis B surface antigen positive or Hepatitis B core antibody positive at screening
* Antibodies to Hepatitis C at screening
* Malignancy or history of malignancy except for treated \[i.e., cured\] basal-cell skin carcinomas
* Any condition, including the presence of laboratory abnormalities, that 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
* Psoriasis flare within 4 weeks of screening
* Topical therapy within 2 weeks of randomization
* Systemic therapy for psoriasis within 4 weeks of randomization
* Use of phototherapy within 4 weeks of randomization \[(i.e., Ultraviolet (UVB), Psoralens and long-wave ultraviolet radiation (PUVA)\]
* Adalimumab, etanercept, efalizumab or infliximab within 12 weeks of randomization
* Alefacept within 24 weeks of randomization
* Investigational drug within 4 weeks of randomization, or 5 pharmacokinetic/pharmacodynamic half lives, if known (whichever is longer)
* Prolonged sun exposure or use of tanning booths or other ultraviolet light sources
B: Inclusion Criteria:

* Diagnosis of Psoriasis for 6 MO
* BSA 10%
* PASI 12 or above
* PGA 3 or above

Exclusion Criteria:

* Previous exposure to either etanercept or ABT-874
C: Inclusion criteria:

* Subject is male or female, aged ≥ 18 years to ≤ 70 years at Screening. Female subjects must either be postmenopausal (at least 1 year), permanently sterilized or, if of childbearing potential, must be willing to use at least 2 effective methods of contraception, including a barrier method during the study period. Effective methods of contraception are methods of birth control, which result in a low failure rate when used consistently and correctly, such as implants, injectables, oral contraceptives, progesterone-releasing intrauterine systems or the TCu 380A intrauterine device, complete sexual abstinence, or vasectomized partner. Male subjects with partners of childbearing potential must be willing to use a condom when sexually active. Both male and female subjects must use the above mentioned contraception for 20 weeks after administration of study drug (anticipated 5 half-lives)
* Subject has had a confirmed diagnosis of mild to moderate plaque-type psoriasis for at least 6 months involving ≤ 5 % of body surface area (BSA) (excluding the scalp)
* Subject has a body mass index of ≤ 35 kg/m\^2 at Screening
* Subject has a minimum of 2 psoriatic lesions with at least 1 plaque in a site suitable for biopsy

Exclusion Criteria:

* Female subject who is pregnant, or plans to become pregnant during the study, or lactating, or sexually active with childbearing potential who is not using a medically accepted birth control method
* Subject has received systemic nonbiologic psoriasis therapy (methotrexate \[MTX\], steroids, cyclophosphamide) or psoralen plus ultraviolet A (PUVA)/ultraviolet A (UVA) phototherapy within 4 weeks prior to Screening
* Subject has received treatment with biologic agents within 12 months prior to the study
* Subject has received live attenuated vaccination within 6 weeks prior to Screening or intends to have such a vaccination during the course of the study
* Subject has received any investigational drug or experimental procedure within 90 days or 5 half-lives, whichever is longer, prior to IMP administration
* Subject requires treatment with a nonsteroidal anti-inflammatory drug during the study period. Paracetamol will be permitted for use as an antipyretic and/or analgesic
* Subject has an active infection (eg, sepsis, pneumonia, abscess) or has had a serious infection (resulting in hospitalization or requiring parenteral antibiotic treatment) within 6 weeks prior to IMP administration. When in doubt, the Investigator should confer with the UCB Study Physician
* Subject has a history of a positive tuberculosis (TB) test or evidence of possible TB or latent TB infection at Screening that cannot be attributed to a prior Bacillus Calmette-Guérin inoculation
* Subject has renal or liver impairment, defined as:

  * For women, serum creatinine level ≥ 125 μmol/L; for men, ≥ 135 μmol/L, or
  * ALT and aspartate aminotransferase ≥ 2x ULN, or
  * Alkaline phosphatase and bilirubin \> 1.5x ULN (an isolated bilirubin \> 1.5x ULN is acceptable if bilirubin is fractionated and direct bilirubin is \< 35 %)
* Subject has active neoplastic disease or history of neoplastic disease within 5 years of Screening (except for basal or squamous cell carcinoma of the skin or carcinoma in situ that has been definitively treated with standard of care)
D: Inclusion Criteria:

* Have had a diagnosis of plaque type psoriasis (psoriasis vulgaris);
* Have plaque-type psoriasis covering at least 10% of total body surface area
* Considered by dermatologist investigator to be a candidate for systemic therapy or phototherapy of psoriasis

Exclusion Criteria:

* Non-plaque or drug induced forms of psoriasis
* Cannot discontinue current systemic and/or topical therapies for the treatment of psoriasis
* Cannot discontinue phototherapy
* Any uncontrolled significant medical condition
