Title: A Phase 3, Multi-Site, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study Of The Efficacy And Safety Of 2 Oral Doses Of CP-690,550 In Subjects With Moderate To Severe Chronic Plaque Psoriasis
Brief Summary: The main objective of this study is to compare the effects of CP-690,550 with the effects of placebo in patients being treated for moderate to severe chronic plaque psoriasis. This one-year study will also evaluate the safety and tolerability of CP-690,550 versus placebo.


Options:
A: Inclusion Criteria:

Subjects eligible for inclusion in this study must have fulfilled all of the following criteria:

1. Men or Women of at least 18 years of age at time of Screening
2. Subjects able to understand and communicate with the investigator and comply with the requirements of the study and must have given a written, signed and dated informed consent before any study related activity was performed. Where relevant, a legal representative signed the informed study consent according to local laws and regulations.
3. Chronic plaque-type psoriasis present for at least 6 months and diagnosed before Randomization.
4. Moderate to severe psoriasis as defined at Randomization by:

   * PASI score of 12 or greater, and
   * IGA mod 2011 score of 3 or greater (based on a scale of 0 - 4), and
   * Body Surface Area (BSA) affected by plaque-type psoriasis of 10% or greater.
5. Candidate for systemic therapy. This is defined as a subject having moderate to severe chronic plaque-type psoriasis that is inadequately controlled by

   * Topical treatment and/or
   * Phototherapy and/or
   * Previous systemic therapy

Exclusion Criteria:

1. Forms of psoriasis other than chronic plaque-type (e.g., pustular, erythrodermic and guttate psoriasis) at Screening or Randomization.
2. Ongoing use of prohibited treatments. Washout periods detailed in the protocol had to be adhered to. Subjects not willing to limit UV light exposure (e.g., sunbathing and/or the use of tanning devices) during the course of the study were considered not eligible for this study since UV light exposure was prohibited.

   Note: administration of live vaccines 6 weeks prior to Randomization or during the study period was also prohibited.
3. Previous exposure to secukinumab (AIN457) or any other biologic drug directly targeting IL-17 or the IL-17 receptor.
4. Use of other investigational drugs at the time of enrollment, or within 5 half-lives of enrollment, or within 30 days until the expected pharmacodynamic effect had returned to baseline, whichever is longer; or longer if required by local regulations.
5. Pregnant or nursing (lactating) women, where pregnancy was defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.
6. History of lymphoproliferative disease or any known malignancy or history of malignancy of any organ system treated or untreated within the past 5 years, regardless of whether there was evidence of local recurrence or metastases (except for Bowen's disease, or basal cell carcinoma or actinic keratoses that had been treated with no evidence of recurrence in the past 12 weeks; carcinoma in situ of the cervix or non-invasive malignant colon polyps that have been removed).
7. History of hypersensitivity to any of study drug constituent
B: Inclusion Criteria:

* 18 years or older with diagnosis for at least 12 months of moderate to severe plaque psoriasis covering at least 10% of body surface area
* A Psoriasis Area and Severity Index (PASI) score of 12 or greater
* Are considered to be candidates for systemic or light therapy
* Have no evidence of active or latent tuberculosis

Exclusion Criteria:

* Non-plaque or drug-induced forms of psoriasis
* Cannot discontinue current oral, injectible or topical therapy for psoriasis or cannot discontinue phototherapy (PUVA or UVB)
* Any uncontrolled significant medical condition
C: Inclusion Criteria:

* Have been diagnosed with plaque psoriasis for at least 6 months.
* Have plaque psoriasis covering at least 15% of their total body.
* Be a candidate for phototherapy or systemic treatment of psoriasis (either naïve or history of previous treatment).
* Be willing and able to comply with scheduled visits, treatment plan and other study procedures.

Exclusion Criteria:

* Currently have non-plaque forms of psoriasis or drug-induced psoriasis.
* Subject cannot discontinue systemic therapies and/or topical therapies for the treatment of psoriasis and cannot discontinue phototherapy.
* Subject is participating in another trial using an investigational agent or procedure.
* Women who are pregnant or breast-feeding or considering becoming pregnant.
D: Inclusion criteria:

* Body Mass Index (BMI) \>/= 18.5 and \< 40 kg/m²
* Patients with stable moderate to severe chronic plaque-type psoriasis with or without psoriatic arthritis involving \>/= 10% body surface area, with disease severity PASI \>/= 12 and sPGA score of moderate and above (score of at least 3) at screening visit and visit 2 (randomisation), as assessed by the investigator
* Psoriasis disease duration of at least 6 months prior to screening, as assessed by the investigator
* Patients must be candidates for systemic psoriasis treatment or phototherapy, as assessed by the investigator
* Patients must be suitable candidates for ustekinumab (Stelara®) therapy as given in the local labelling
* Patient must give informed consent and sign an approved consent form prior to any study procedures in accordance with GCP and local legislation

Exclusion criteria:

* Patients with guttate, erythrodermic, or pustular psoriasis and patients with drug-induced psoriasis, as diagnosed by the investigator
* Evidence of current or previous clinically significant disease, medical condition other than psoriasis, or finding of the medical examination (including vital signs and ECG), that in the opinion of the investigator, would compromise the safety of the patient or the quality of the data. This criterion provides an opportunity for the investigator to exclude patients based on clinical judgment, even if other eligibility criteria are satisfied. (Psoriatic arthritis is not considered an exclusion criterion)
* Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders, diseases of the central nervous system (such as epilepsy) or psychiatric disorders or neurological disorders, or history of orthostatic hypotension, fainting spells or blackouts, that in the investigator's judgement, could jeopardize the safe conduct of the study.
* Clinically important acute or chronic infections including hepatitis and HIV.

With regards to tuberculosis the following applies:

Have signs or symptoms suggestive of current active or latent TB upon medical history, physical examination and/or a chest radiograph (both posterior-anterior and lateral views, taken within 3 months prior to the first administration of study drug and read by a qualified radiologist).

Have history of latent or active TB prior to screening, except for patients who have documentation of having completed an adequate treatment regimen at least 6 months prior to the first administration of study agent.

Have positive IGRA testing (QuantiFERON-TB Gold) within 2 months prior to or during screening, in which active TB has not been ruled out, except for patients with history of latent TB and documentation of having completed an adequate treatment regimen at least 6 months prior to the first administration of study agent.

* Have had a live vaccination \</= 12 weeks prior to randomisation (visit 2). Patients must agree not to receive a live vaccination during the study. No BCG vaccines should be given for one year prior to randomisation (visit 2), during the study and for one year after last administration of study drug (according to the Stelara® SPC).
* History of clinically significant hypersensitivity to a systemically administered biologic agent or its excipients
* History of malignancy in the past 5 years or suspicion of active malignant disease except treated cutaneous squamous cell or basal cell carcinoma

* Use of biologic agents within 12 weeks (infliximab, etanercept, adalimumab, other biologics) prior to treatment, systemic anti-psoriatic medications or phototherapy within 4 weeks prior to treatment, or topical anti-psoriasis medications within 2 weeks prior to treatment
