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:

Diagnosis of PsA classified by CASPAR criteria and with symptoms for at least 6 months with moderate to severe PsA who must have at BSL ≥3 tender joints out of 78 and ≥3 swollen joints out of 76 (dactylitis of a digit counts as one joint each).

* Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies negative at screening.
* Diagnosis of active plaque psoriasis or nail changes consistent with psoriasis or a documented history of plaque psoriasis.
* Subjects with PsA should have taken NSAIDs for at least 4 weeks prior to randomization with inadequate control of symptoms or at least one dose if stopped due to intolerance to NSAIDs.-Subjects who are regularly taking NSAIDs as part of their PsA therapy are required to be on a stable dose for at least 2 weeks before study randomization and should remain on a stable dose up to Week 24.
* Subjects taking corticosteroids must be on a stable dose of ≤10 mg/day prednisone or equivalent for at least 2 weeks before randomization and should remain on a stable dose up to Week 24.
* Subjects taking MTX (≤ 25 mg/week) are allowed to continue their medication if the dose is stable for at least 4 weeks before randomization and should remain on a stable dose up to Week 52.
* Subjects on MTX must be on folic acid supplementation at randomization.
* Subjects who are on a DMARD other than MTX must discontinue the DMARD 4 weeks prior to randomization visit except for leflunomide, which has to be discontinued for 8 weeks prior to randomization unless a cholestyramine wash-out has been performed.
* Subjects who have been on a TNFα inhibitor must have experienced an inadequate response to previous or current treatment with a TNFα inhibitor given at an approved dose for at least 3 months or have stopped treatment due to safety/tolerability problems after at least one administration of a TNFα inhibitor.
* Subjects who have previously been treated with TNFα inhibitors (investigational or approved) will be allowed entry into study after appropriate wash-out period prior to randomization

Exclusion Criteria:

Chest X-ray or chest MRI with evidence of ongoing infectious or malignant process. - Subjects taking high potency opioid analgesics.

* Previous exposure to secukinumab or other biologic drug directly targeting IL-17 or IL-17 receptor. - Ongoing use of prohibited psoriasis treatments / medications (e.g., topical corticosteroids, UV therapy) at randomization.
* Any intramuscular or intravenous or intra-articular corticosteroid treatment within 4 weeks before randomization.
* Subjects who have ever received biologic immunomodulating agents except for those targeting TNFα (investigational or approved).
* Previous treatment with any cell-depleting therapies including but not limited to anti- CD20, investigational agents
* Other protocol-defined exclusion criteria do apply
B: Inclusion Criteria:
