Title: A Multicenter Study With a Randomized, Double-Blind, Placebo-Controlled Induction Dosing Period Followed by a Randomized Maintenance Dosing Period and a Long- Term Extension Period to Evaluate the Efficacy and Safety of LY2439821 in Patients With Moderate-to-Severe Plaque Psoriasis
Brief Summary: This study will assess the safety and efficacy of LY2439821 compared to placebo in participants with moderate to severe, chronic plaque psoriasis.


Options:
A: Inclusion Criteria:

* Present with chronic plaque psoriasis based on a confirmed diagnosis of chronic psoriasis vulgaris for at least 6 months prior to randomization
* At least 10% Body Surface Area (BSA) of Psoriasis at screening and at randomization
* 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 randomization
* Candidate for phototherapy and/or systemic therapy
* Men must agree to use a reliable method of birth control during the study
* Women must agree to use 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
* Clinically significant flare of psoriasis during the 12 weeks prior to randomization
* Concurrent or recent use of any biologic agent
* Received systemic psoriasis therapy \[such as psoralen and ultraviolet A (PUVA) light therapy\] or phototherapy 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
* Have participated in any study with interleukin (IL)-17 antagonists, including LY2439821
* Serious disorder or illness other than plaque psoriasis
* Serious infection within the last 3 months
* Breastfeeding or nursing (lactating) women.
B: Inclusion Criteria:

* Adult participants (≥18 years of age) with a diagnosis of moderate-to-severe chronic plaque psoriasis (defined by ≥10% body surface area \[BSA\] involvement, "moderate" or greater score on the Physician's Global Assessment \[PGA\] scale, and PASI score ≥12 at Baseline)
* Participants must have a diagnosis of predominantly plaque psoriasis for ≥6 months (as determined by interview and confirmation of diagnosis through physical examination by investigator) and be considered candidates for phototherapy or systemic therapy. Participants with psoriatic arthritis may be included in the study

Exclusion Criteria:

* Nonplaque forms of psoriasis specifically erythrodermic psoriasis, predominantly pustular psoriasis, medication-induced or medication-exacerbated psoriasis, or new onset guttate psoriasis
* Participants who will require oral or injectable corticosteroids during the trial
* Presence of any infection requiring treatment with systemic antibiotics within 2 weeks prior to Screening, or serious infection (eg, pneumonia, cellulitis, bone or joint infections) requiring hospitalization or treatment with intravenous antibiotics within 8 weeks prior to Screening
* Participants with evidence of active or untreated latent tuberculosis (TB) according to Screening criteria specified in the protocol. (Prophylactic treatment for latent TB as per local guidelines must be initiated at least 4 weeks prior to treatment with study medication)
* Previous exposure to any agents targeting interleukin-12 (IL-12) and/or Interleukin-23 (IL-23)
* Participants with prior exposure to two or more tumor necrosis factor (TNF) antagonists with discontinuation due to lack of efficacy.
C: Inclusion criteria:

1. Men or women ≥ 18 and ≤ 75 years of age at time of screening
2. Stable moderate to severe plaque psoriasis for at least 6 months before baseline
3. Moderate to severe psoriasis defined at screening and baseline by:

   Body surface area (BSA) affected by plaque psoriasis of 10% or greater, and PASI score of 12 or greater, and static physician's global assessment score of 3 or greater
4. No known history of active tuberculosis
5. Subject is a candidate for systemic therapy or phototherapy procedures
6. Previous failure, inadequate response, intolerance, or contraindication to at least 1 conventional anti-psoriatic systemic therapy

Exclusion Criteria:

1. Forms of psoriasis or other skin conditions at the time of the screening visit (eg, eczema)
2. Ongoing use of prohibited treatments
3. Prior use of 2 or more biologics for treatment of psoriasis
4. Previous receipt of adalimumab or a biosimilar of adalimumab

Other Inclusion/Exclusion criteria may apply
D: Inclusion Criteria:

* Subject was age 18 or older and in good health (Investigator discretion) with a recent stable medical history.
* Subject had a clinical diagnosis of psoriasis for at least 6 months, had moderate to severe plaque psoriasis.
* Subject was able and willing to self-administer sc injections or had available qualified person(s) to administer sc injections

Exclusion Criteria:

* Subject had previously received anti-TNF therapy.
* Subject cannot discontinue systemic therapies and/or topical therapies for the treatment of psoriasis and cannot avoid UVB or PUVA phototherapy
* Subject cannot avoid excessive sun exposure
* Subject is taking or requires oral or injectable corticosteroids
* Subject considered by the investigator, for any reason, to be an unsuitable candidate for the study
* Female subject who is pregnant or breast-feeding or considering becoming pregnant
