Title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study Comparing the Efficacy and Safety of LY2439821 to Etanercept and Placebo in Patients With Moderate-to-Severe Plaque Psoriasis
Brief Summary: This study will assess the safety and efficacy of ixekizumab (LY2439821) compared to etanercept and placebo in participants with moderate to severe chronic plaque psoriasis.


Options:
A: Inclusion Criteria:

* At least 10% Body Surface Area (BSA) of psoriasis at screening and at first dose of study drug
* Static Physician Global Assessment (sPGA) score of at least 3 and Psoriasis Area and Severity Index (PASI) score of at least 12 at screening and at first dose of study drug
* Candidate for phototherapy and/or systemic therapy
* Men must agree to use a reliable method of birth control or remain abstinent during the study
* Women must agree to use reliable birth control or remain abstinent during the study and for at least 12 weeks after stopping treatment

Exclusion Criteria:

* Pustular, erythrodermic, and/or guttate forms of psoriasis
* History of drug-induced psoriasis
* Prior use of etanercept
* Clinically significant flare of psoriasis during the 12 weeks prior to randomization
* Concurrent or recent use of any biologic agent
* Received non-biologic systemic psoriasis therapy or phototherapy (including psoralens and ultraviolet A \[PUVA\], ultraviolet B \[UVB\]) within the previous 4 weeks; or had topical psoriasis treatment within the previous 2 weeks prior to randomization
* Cannot avoid excessive sun exposure or use of tanning booths for at least 4 weeks prior to randomization and during the study

* Adults over 18 years of age with a diagnosis of chronic moderate to severe plaque psoriasis for at least 12 months; in generally good health; on stable dose of non-prohibited medications; able to stop current psoriasis therapy (systemic or topical) for several weeks prior to and during study participation.

Exclusion Criteria:

* Serious underlying disease including viral disorders such as hepatitis or HIV or skin condition that would interfere with skin biopsies or evaluation of psoriasis; conditions that could interfere with drug absorption after oral administration; history of malignancy or auto-immune disease.
* Use of oral or injected corticosteroids (steroids).
C: Inclusion Criteria:

* Diagnosis of plaque-type psoriasis with or without psoriatic arthritis for at least 6 months prior to first administration of any study agent
* Must be a candidate for phototherapy or systemic treatment for psoriasis (either new to treatment or having had previous treatment)
* Must be considered, in the opinion of the investigator, suitable candidates for adalimumab therapy
* If a woman, she must be postmenopausal, or if premenopausal, she must be either surgically sterile, practicing a highly effective method of birth control, or not heterosexually active during the study and for 5 months after receiving the last dose of study drug
* If a man, he must agree to use a double-barrier method of birth control (or must have been surgically sterilized) and to not donate sperm during the study and for 5 months after receiving the last dose of study drug.

Exclusion Criteria:

* History of or current signs or symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, cerebral, or psychiatric disease
* Has a contra-indication to anti-TNF therapy
* Has a history of chronic or recurrent infectious disease
* Has a nonplaque form of psoriasis or has drug-induced psoriasis
* Has been previously treated with adalimumab
* Has received any therapeutic agent directly targeted to IL-12, IL-17, or IL-23, (including but not limited to ustekinumab, briakinumab \[ABT-874\], AIN457, and SCH900222) within 6 months of the first administration of study agent.
D: Inclusion Criteria:Patients eligible for inclusion in this study have to fulfill all of the following 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 Baseline ≥3 tender joints out of 78 and ≥3 swollen out of 76 (dactylitis of a digit counts as one joint each)
* Rheumatoid factor and anti-CCP antibodies negative at screening
* Diagnosis of active plaque psoriasis or nail changes consistent with psoriasis or 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 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.

Exclusion Criteria:Patients fulfilling any of the following criteria are not eligible for inclusion in this study:

* Subjects taking high potency opioid analgesics (e.g. methadone, hydromorphone, morphine)
* 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. The following wash out periods need to be observed:
* Oral or topical retinoids 4 weeks
* Photochemotherapy (e.g. PUVA) 4 weeks
* Phototherapy (UVA or UVB) 2 weeks
* Topical skin treatments (except in face, scalp and genital area during screening, only corticosteroids with mild to moderate potency) 2 weeks
