Title: A Randomized, Double-blind, Placebo Controlled, Multicenter Regimen Finding Study of Subcutaneously Administered AIN457, Assessing Psoriasis Area and Severity Index (PASI) Response in Patients With Moderate to Severe Chronic Plaque-type Psoriasis
Brief Summary: The purpose of the study is to determine whether, in patients with moderate to severe plaque-type psoriasis, AIN457 administered subcutaneously reduces the severity of psoriasis symptoms and the extent to which the patient's body area is affected by the disease (compared to placebo).


Options:
A: Inclusion Criteria:

* Men or women at least 18 years of age at time of consent
* Chronic plaque-type psoriasis diagnosed for at least 6 months at time of randomization
* At time of randomization, moderate to severe psoriasis as defined by:

  * PASI score of 12 or greater and
  * IGA score of 3 or greater and
  * Body Surface Area (BSA) affected by plaque-type psoriasis of 10 % or greater
* At screening and randomization, chronic plaque-type psoriasis considered inadequately controlled by:

  * topical treatment and/or
  * phototherapy and/or
  * previous systemic therapy

Exclusion Criteria:

* Patients meeting any of the following criteria will be excluded from entry into the study:
* Forms of psoriasis other than chronic plaque-type (e.g., pustular, erythrodermic and guttate psoriasis) at screening or randomization
* Drug-induced psoriasis (i.e. new onset or current exacerbation from beta-blockers, calcium channel inhibitors or lithium) and randomization
* Ongoing use of prohibited psoriasis treatments (e.g., topical or systemic corticosteroids, UV therapy) at randomization. Washout periods detailed in the study protocol have to be adhered to

Female subjects must either be postmenopausal (at least 1 year), permanently sterilized or, if of childbearing potential, must be willing to use at least 2 effective methods of contraception, including a barrier method during the study period. Effective methods of contraception are methods of birth control, which result in a low failure rate when used consistently and correctly, such as implants, injectables, oral contraceptives, progesterone-releasing intrauterine systems or the TCu 380A intrauterine device, complete sexual abstinence, or vasectomized partner. Male subjects with partners of childbearing potential must be willing to use a condom when sexually active. Both male and female subjects must use the above mentioned contraception for 20 weeks after administration of study drug (anticipated 5 half-lives)
* Subject has had a confirmed diagnosis of mild to moderate plaque-type psoriasis for at least 6 months involving ≤ 5 % of body surface area (BSA) (excluding the scalp)
* Subject has a body mass index of ≤ 35 kg/m\^2 at Screening
* Subject has a minimum of 2 psoriatic lesions with at least 1 plaque in a site suitable for biopsy

Exclusion Criteria:

* Female subject who is pregnant, or plans to become pregnant during the study, or lactating, or sexually active with childbearing potential who is not using a medically accepted birth control method
* Subject has received systemic nonbiologic psoriasis therapy (methotrexate \[MTX\], steroids, cyclophosphamide) or psoralen plus ultraviolet A (PUVA)/ultraviolet A (UVA) phototherapy within 4 weeks prior to Screening
* Subject has received treatment with biologic agents within 12 months prior to the study
* Subject has received live attenuated vaccination within 6 weeks prior to Screening or intends to have such a vaccination during the course of the study
* Subject has received any investigational drug or experimental procedure within 90 days or 5 half-lives, whichever is longer, prior to IMP administration
* Subject requires treatment with a nonsteroidal anti-inflammatory drug during the study period. Paracetamol will be permitted for use as an antipyretic and/or analgesic

* 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.
