Title: A Phase 3 Multicenter Study to Assess the Efficacy and Safety of Etanercept 50 mg Twice Weekly in Psoriasis
Brief Summary: The purpose of this study is to determine the effect of etanercept 50 mg twice weekly compared to placebo over 12 weeks on the psoriasis area and severity index (PASI) in subjects with psoriasis. This study will also evaluate the safety and tolerability of etanercept 50 mg twice weekly; determine the effect of etanercept 50 mg twice weekly on patient reported outcomes (PRO); and characterize the pharmacokinetics (PK) profile of etanercept 50 mg twice weekly.


Options:
A: Inclusion Criteria: - Active, but clinically stable, plaque psoriasis involving greater than or equal to 10% of the body surface area - A minimum PASI score of 10 obtained during the screening period Exclusion Criteria: - Active guttate, erythrodermic, or pustular psoriasis at the time of the screening visit - Evidence of skin conditions at the time of the screening visit (e.g., eczema) that would interfere with evaluations of the effect of an investigational product on psoriasis
B: Key Inclusion Criteria:

* Able to understand and communicate with the investigator, willing and capable to comply with all study procedures, and provide written signed and dated informed consent (personally or by a witness) before any assessment is performed.
* Aged 18 to 50 years inclusive.
* New-onset plaque psoriasis with appearance of the first psoriasis plaques within the last 12 months before randomization and naïve to any systemic treatment and phototherapy (Arm A1, Arm A2, and Arm B1). Episodes of mild psoriasis, which occurred at least 3 years before screening and resolved spontaneously within 6 months will be accepted.
* Chronic plaque psoriasis with appearance of the first psoriasis symptoms 5 years or longer and intolerance or inadequate response to phototherapy or any systemic treatment including biologicals, except for IL-17A inhibitors (Arm C1 and Arm C2).
* Moderate to severe plaque psoriasis defined at screening and baseline by PASI \>= 10, and body surface area (BSA) \>= 10%, and IGA mod 2011 \>= 3.

Key Exclusion Criteria:

* Forms of psoriasis other than plaque-type (e.g., pustular, erythrodermic, guttate, light sensitive, and drug induced).
* Ongoing use of prohibited treatments.
* Previous treatment with phototherapy or any systemic treatment.
* Pregnant or nursing (lactating) women.
* Women of childbearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during the Treatment period or longer if required by locally approved prescribing information (e.g., 20 weeks in the EU and countries where applicable for secukinumab).
C: Key Eligibility Criteria

* Male or female
* Have had a diagnosis of plaque-type psoriasis at least 6 months prior to the first administration of study agent (subjects with concurrent psoriatic arthritis may be enrolled).
* Have plaque-type psoriasis covering at least 10% of their total BSA at screening and at the time of the first administration of study agent.
* Have a PGA score of ≥ 3 at screening and at the time of the first administration of study agent.
D: Inclusion Criteria:

* Subject has had stable moderate to severe plaque psoriasis for at least 6 months
* Subject has received at least one previous phototherapy or systemic psoriasis therapy or has been a candidate to receive phototherapy or systemic psoriasis therapy in the opinion of the investigator.
* Subject has involved BSA ≥ 10% and PASI ≥ 12 at screening and at baseline.

Exclusion Criteria:

* Subject diagnosed with erythrodermic psoriasis, pustular psoriasis, medication-induced, or medication-exacerbated psoriasis.
* Evidence of skin conditions at the time of the screening visit (eg, eczema, guttate psoriasis) that would interfere with evaluations of the effect of IP on psoriasis.
* Subject has any active CTCAE grade 2 or higher infection
* Subject has a significant concurrent medical condition or laboratory abnormalities, as defined in the study protocol.
* Subject has used the following therapies within 14 days of the first dose: UVB therapy or topical psoriasis therapies other than Class I or II topical steroids
* Subject has used the following therapies within 28 days of the first dose: Class I or II topical steroids, UVA therapy (with or without psoralen), or systemic psoriasis therapies
* Subject has used the following therapies within 3 months of the first dose: adalimumab, alefacept, etanercept, infliximab, certolizumab, or live vaccines
* Subject has used an anti-IL12/IL23 inhibitor within 6 months of the first dose
* Subject has previously used an anti-IL17 biologic therapy, efalizumab, or rituximab
