Title: A Phase 3b, Randomized, Double-blind, Active-controlled, Multicenter Study to Evaluate a "Subject-tailored" Maintenance Dosing Approach in Subjects With Moderate-to-Severe Plaque Psoriasis
Brief Summary: The purpose of the study is to assess the effect of extending maintenance dosing intervals beyond 12 weeks on the clinical efficacy and safety of ustekinumab in subjects with moderate-to-severe plaque psoriasis.


Options:
A: Inclusion Criteria:

* Subjects must give a written, signed and dated informed consent
* Chronic plaque-type psoriasis present for at least 6 months before randomization
* Moderate to severe plaque psoriasis as defined at randomization by:

  * PASI score of ≥12 and
  * Body Surface Area (BSA) affected by plaque-type psoriasis ≥10% and
  * IGA mod 2011 ≥3 (based on a scale of 0-4)
* Candidate for systemic therapy, defined as having psoriasis inadequately controlled by:

  * Topical treatment (including topical corticosteroids) and/or
  * Phototherapy and/or
  * Previous systemic therapy

Exclusion Criteria:

* Forms of psoriasis other than plaque psoriasis
* Drug-induced psoriasis
* Ongoing use of prohibited treatments
* Previous exposure to secukinumab or any other biologic drug directly targeting IL-17A or IL-17RA, or ustekinumab, or any therapies targeting IL-12 or IL-23
* Use of any other investigational drugs within 5 half-lives of the investigational treatment before study drug initiation
* Pregnant or nursing (lactating) women

Other protocol-defined inclusion/exclusion criteria may apply
B: Inclusion Criteria:

* Subjects with chronic, plaque-type psoriasis for at least 6 months
* Must have moderate to severe psoriasis based on PASI greater than 12, IGA greater than 3, and greater than 10% body surface area
* Must be inadequately controlled by prior treatments (topicals, phototherapy, and/or systemic therapies)

Exclusion Criteria:

* Forms of psoriasis other than chronic, plaque-type (such as pustular, erythrodermic and guttate psoriasis)
* Drug induced psoriasis
* Use of other psoriasis treatments during the study
* Prior use of etanercept
* Prior use of secukinumab or any other drug that target IL-17 (interleukin 17) or the IL-17 receptor
* Pregnant or lactating women; women who do not agree to use contraception during the study and for 16 weeks after stopping treatment
* Significant medical problems such as uncontrolled high blood pressure, congestive heart failure, etc.
* History of an ongoing, chronic or recurrent infection or evidence of tuberculosis
* Allergy to rubber or latex

Other protocol-defined inclusion/exclusion criteria may apply
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:

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
