Primary Outcome Measures:

Incidence and severity of adverse events during treatment. [ Time Frame: At every visit until last observation ] [ Designated as safety issue: Yes ]
Incidence of clinical laboratory abnormalities and change from baseline (in this and/or prior study) in clinical laboratory values during treatment. [ Time Frame: At every visit until last observation ] [ Designated as safety issue: Yes ]
Incidence of investigator-reported clinically significant changes in physical examination from baseline (in this and/or prior study) during treatment. [ Time Frame: At every visit until last observation ] [ Designated as safety issue: Yes ]
Incidence of vital sign (blood pressure and heart rate) abnormalities and change from baseline (in this and/or prior study) in vital sign measures during treatment. Incidence of electrocardiogram (ECG) abnormalities and change from baseline (in this [ Time Frame: At every visit until last observation ] [ Designated as safety issue: Yes ]
and/or prior study) in ECG measurements during treatment. [ Time Frame: At every visit until last observation ] [ Designated as safety issue: Yes ]
Summary of adjudicated cardiovascular endpoints. Summary of malignancies confirmed by central laboratory pathologist over read of biopsies. [ Time Frame: At every visit until last observation ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Physician's Global Assessment (PGA) response ie, the proportion of subjects achieving a PGA of "clear" or "almost clear" at various time points. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
Psoriasis Area and Severity Index 75 (PASI75) response ie, the proportion of subjects achieving at least a 75% reduction in PASI relative to baseline (in this and/or prior study) at various time points. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
The actual and change from baseline (in this and/or prior study) in PASI and PASI component scores at various time points. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
Proportion of subjects achieving at least a 50% and 90% reduction in PASI relative to baseline (in this and/or prior study) (ie, PASI50 and PASI90, respectively) at various time points. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
Proportion of subjects with a PASI score >= 125% of the baseline PASI score (in this and/or prior study) at any time point. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
The actual and change from baseline (in this and/or prior study) in the Itch Severity Item (ISI) score at various time points. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
The actual and change from baseline (in this and/or prior study) on the Dermatology Life Quality Index (DLQI) score at various time points. [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
Other patient reported outcome (PRO) measures to be assessed at various time points, including: -Short Form-36 Health Survey (Version 2, Acute) (SF-36); -Patient Global Assessment (PtGA); -Euro-Qol 5 Dimensions (EQ-5D); -Psoriasis Healthcare Resource [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
Utilization Questionnaire (Ps-HCRU). [ Time Frame: various timepoints throughout study ] [ Designated as safety issue: No ]
