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.

* 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
B: 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.

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

* Serious infection within the last 3 months
* Breastfeeding or nursing (lactating) women.
