Title: Randomized, Double-Blinded, Placebo-Controlled, Parallel-Design, Dose-Range Finding Study of Subcutaneous Tildrakizumab (SCH 900222/MK-3222) in Subjects With Moderate-to-Severe Chronic Plaque Psoriasis (Study P05495)
Brief Summary: This is a response-driven study of tildrakuzumab for the treatment of moderate to severe chronic plaque psoriasis. The primary study hypothesis is that one or more doses of tildrakizumab will be superior to placebo for the treatment of psoriasis.


Options:
A: Inclusion Criteria:

* Patients with plaque-type psoriasis diagnosed at least 6 months prior and covering at least 10% of total body surface areas
* Have psoriasis area-and-severity index score of \>=12
* Patients who are considered by treating dermatologist to be a candidate for phototherapy or systemic treatment of psoriasis
* Have no history of latent or active TB

Exclusion Criteria:

* Currently have nonplaque forms of psoriasis or drug-induced psoriasis
* Have any therapeutic agent targeted at reducing IL-12 or IL-23
* Have had a BCG vaccination within the previous 12 months
* Have a history of chronic or recurrent infectious disease or who have or have had a serious infection requiring hospitalization or intravenous antibiotics within the previous 2 months
* Have or ever have had a nontuberculous mycobacterial infection or opportunistic infection
* Patients known to be infected with human immunodeficiency virus, hepatitis B, or hepatitis C
* Have current signs or symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, cerebral, or psychiatric disease
* Patients with a malignancy or who have a history of malignancy (with the exception of certain skin cancers and pre-invasive cervical cancer)
B: Inclusion Criteria:

* Adult participants (≥18 years of age) with a diagnosis of moderate-to-severe chronic plaque psoriasis (defined by ≥10% body surface area \[BSA\] involvement, "moderate" or greater score on the Physician's Global Assessment \[PGA\] scale, and PASI score ≥12 at Baseline)
* Participants must have a diagnosis of predominantly plaque psoriasis for ≥6 months (as determined by interview and confirmation of diagnosis through physical examination by investigator) and be considered candidates for phototherapy or systemic therapy. Participants with psoriatic arthritis may be included in the study

Exclusion Criteria:

* Nonplaque forms of psoriasis specifically erythrodermic psoriasis, predominantly pustular psoriasis, medication-induced or medication-exacerbated psoriasis, or new onset guttate psoriasis
* Participants who will require oral or injectable corticosteroids during the trial
* Presence of any infection requiring treatment with systemic antibiotics within 2 weeks prior to Screening, or serious infection (eg, pneumonia, cellulitis, bone or joint infections) requiring hospitalization or treatment with intravenous antibiotics within 8 weeks prior to Screening
* Participants with evidence of active or untreated latent tuberculosis (TB) according to Screening criteria specified in the protocol. (Prophylactic treatment for latent TB as per local guidelines must be initiated at least 4 weeks prior to treatment with study medication)
* Previous exposure to any agents targeting interleukin-12 (IL-12) and/or Interleukin-23 (IL-23)
* Participants with prior exposure to two or more tumor necrosis factor (TNF) antagonists with discontinuation due to lack of efficacy.
C: Inclusion Criteria:

Diagnosis of PsA classified by CASPAR criteria and with symptoms for at least 6 months with moderate to severe PsA who must have at BSL ≥3 tender joints out of 78 and ≥3 swollen joints out of 76 (dactylitis of a digit counts as one joint each).

* Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies negative at screening.
* Diagnosis of active plaque psoriasis or nail changes consistent with psoriasis or a documented history of plaque psoriasis.
* Subjects with PsA should have taken NSAIDs for at least 4 weeks prior to randomization with inadequate control of symptoms or at least one dose if stopped due to intolerance to NSAIDs.-Subjects who are regularly taking NSAIDs as part of their PsA therapy are required to be on a stable dose for at least 2 weeks before study randomization and should remain on a stable dose up to Week 24.
* Subjects taking corticosteroids must be on a stable dose of ≤10 mg/day prednisone or equivalent for at least 2 weeks before randomization and should remain on a stable dose up to Week 24.
* Subjects taking MTX (≤ 25 mg/week) are allowed to continue their medication if the dose is stable for at least 4 weeks before randomization and should remain on a stable dose up to Week 52.
* Subjects on MTX must be on folic acid supplementation at randomization.
* Subjects who are on a DMARD other than MTX must discontinue the DMARD 4 weeks prior to randomization visit except for leflunomide, which has to be discontinued for 8 weeks prior to randomization unless a cholestyramine wash-out has been performed.
* Subjects who have been on a TNFα inhibitor must have experienced an inadequate response to previous or current treatment with a TNFα inhibitor given at an approved dose for at least 3 months or have stopped treatment due to safety/tolerability problems after at least one administration of a TNFα inhibitor.
* Subjects who have previously been treated with TNFα inhibitors (investigational or approved) will be allowed entry into study after appropriate wash-out period prior to randomization

Exclusion Criteria:

Chest X-ray or chest MRI with evidence of ongoing infectious or malignant process. - Subjects taking high potency opioid analgesics.

* Previous exposure to secukinumab or other biologic drug directly targeting IL-17 or IL-17 receptor. - Ongoing use of prohibited psoriasis treatments / medications (e.g., topical corticosteroids, UV therapy) at randomization.
* Any intramuscular or intravenous or intra-articular corticosteroid treatment within 4 weeks before randomization.
* Subjects who have ever received biologic immunomodulating agents except for those targeting TNFα (investigational or approved).
* Previous treatment with any cell-depleting therapies including but not limited to anti- CD20, investigational agents
* Other protocol-defined exclusion criteria do apply
D: Inclusion criteria:

* Moderate and severe plaque-type psoriasis diagnosed for at least 6 months.
* Severity of psoriasis disease meeting all of the following three criteria:
* Psoriasis Area and Severity Index (PASI) score of 12 or greater,
* Investigator's Global Assessment (IGA) score of 3 or greater,
* Total body surface area (BSA) affected of 10% or greater.
* Inadequate control by prior use of topical treatment, phototherapy and/or systemic therapy.

Exclusion criteria:

* Current forms of psoriasis other than chronic plaque-type psoriasis (for example, pustular, erythrodermic, guttate).
* Current drug-induced psoriasis.
* Previous use of secukinumab or any drug that targets IL-17 or IL-17 receptor.
* Significant medical problems such as uncontrolled hypertension, congestive heart failure or a condition that significantly immunocompromises the subject.
