Title: A 48 Weeks Study of Three Different Dose Regimens of BI 655066 Administered Subcutaneously in Patients With Moderate to Severe Chronic Plaque Psoriasis (Randomised, Dose-ranging, Active-comparator-controlled (Ustekinumab), Double-blind Within Dose Groups of BI 655066)
Brief Summary: The overall purpose of this trial is to assess clinical efficacy and safety of different subcutaneous doses of BI 655066 in adult patients with chronic plaque psoriasis in order to select doses for further clinical trials.


Options:
A: Inclusion Criteria:

* Adults over 18 years of age with a diagnosis of chronic moderate to severe plaque psoriasis for at least 12 months; in generally good health; on stable dose of non-prohibited medications; able to stop current psoriasis therapy (systemic or topical) for several weeks prior to and during study participation.

Exclusion Criteria:

* Serious underlying disease including viral disorders such as hepatitis or HIV or skin condition that would interfere with skin biopsies or evaluation of psoriasis; conditions that could interfere with drug absorption after oral administration; history of malignancy or auto-immune disease.
* Use of oral or injected corticosteroids (steroids).
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.
* 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
* Has received any therapeutic agent directly targeted to IL-12, IL-23 (including ustekinumab (Stelara®))
* 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
C: 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).
