Title: A Randomized, Double-blind, Placebo-Controlled, Ascending Single-Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of AMG 827 in Healthy Subjects and Subjects With Moderate to Severe Psoriasis
Brief Summary: This Phase 1 study will evaluate safety, tolerability, PK and PD of AMG 827 when administered as a single SC or IV dose.


Options:
A: Inclusion Criteria: - Subjects who completed study 20030115 or 20030117 qualify to enroll into this study (provided that they meet all inclusion/exclusion criteria). - Heterosexually active men and women of child-bearing potential must agree to use a medically acceptable form of contraception throughout the study. - Subject or designee must have the ability to self-inject investigational product. - Subject must be capable of understanding and giving written voluntary informed consent. - Negative serum pregnancy test less than or equal to 14 days prior to the first dose of investigational product in all female subjects (except those surgically sterile or at least 5 years postmenopausal) Exclusion Criteria: - Active guttate, erythrodermic, or pustular psoriasis at the time of the baseline visit - Any adverse event or infection at the time of the baseline visit or at any time during the previous etanercept psoriasis study which, in the opinion of Amgen or the Investigator, would preclude participation in the study - Presence of a serious infection less than or equal to 30 days prior to the baseline visit - Evidence of skin conditions at the baseline visit (e.g., eczema) that would interfere with evaluations of the effect of investigational product on psoriasis - Previous receipt of anti-TNF agent(s) other than etanercept - Receipt of any investigational product(s), other than etanercept, less than or equal to 30 days prior to first dose of investigational product in this study - Receipt of anti-CD4 or diphtheria IL-2 fusion protein less than or equal to 24 weeks prior to first dose of investigational product in this study - Psoralen and ultraviolet A (PUVA) light therapy less than or equal to 14 days prior to first dose of investigational product in this study - Ultraviolet A (UVA) light therapy less than or equal to 14 days prior to first dose of investigational product in this study - Ultraviolet B (UVB) light therapy less than or equal to 14 days prior to first dose of investigational product in this study - Receipt of any other systemic psoriasis therapy or oral or parenteral corticosteroids less than or equal to 14 days prior to first dose of investigational product in this study - Pregnant or breast-feeding females - Significant concurrent medical conditions prior to enrollment, including: uncontrolled hypertension (defined as systolic blood pressure measurement of greater than 180 mm Hg or an untreated diastolic blood pressure of greater than 110 mm Hg); myocardial infarction less than or equal to 52 weeks prior to baseline visit; unstable angina pectoris; uncompensated congestive heart failure; severe pulmonary disease requiring hospitalization or supplemental oxygen therapy; diagnosis of multiple sclerosis or any other demyelinating disease; insulin-dependent diabetes mellitus; history of cancer (other than in-situ cervical cancer or resected cutaneous basal cell or squamous cell carcinoma) less than or equal to 5 years prior to administration of first dose of investigational product; open cutaneous ulcers; known human immunodeficiency virus (HIV), hepatitis B surface antigen (HbsAg) or hepatitis C virus (HCV) positive; any condition that might cause this study to be detrimental to the subject, in the judgment of the investigator.
B: Inclusion Criteria:

* Subject has involved body surface area (BSA) ≥ 10%, PASI ≥ 12, and sPGA ≥ 3 at screening and at baseline

Exclusion Criteria:

* Subject diagnosed with erythrodermic psoriasis, pustular psoriasis, guttate psoriasis, medication-induced psoriasis, or other skin conditions at (eg, eczema) that would interfere with study evaluations
* Subject has known history of Crohn's disease

* Healthy male or female between 18 to 45 years of age, inclusive at the time of screening
* Additional inclusion criteria apply

Part B:

* 18 - 55 years old inclusive at Screening
* Active but clinically stable, plaque psoriasis
* Psoriasis involving ≥ 10% of the body surface area
* A minimum PASI score of ≥ 10 obtained during the screening period
* Additional inclusion criteria apply

Exclusion Criteria:

Part A:

* History or evidence of a clinically significant disorder (including but not limited to cardiopulmonary, oncologic, renal, metabolic, hematologic or psychiatric), condition or disease that, in the opinion of the Investigator and Amgen physician would pose a risk to subject safety or interfere with the study evaluation, procedures or completion
* Underlying condition that predisposes the subject to infections (eg, uncontrolled diabetes - HbA1c \> 7%, history of splenectomy)
* Additional exclusion criteria apply

Part B:

* Active guttate, erythrodermic, or pustular psoriasis at the time of the screening visit
* Evidence of skin conditions other than psoriasis (eg, eczema) at the time of the screening visit or between the screening visit and study drug initiation that would interfere with evaluations of the effect of investigational product on psoriasis
* Any condition that, in the judgment of the investigator, might cause this study to be detrimental to the subject
* Additional exclusion criteria apply
