Primary Outcome Measures
NameTimeMethod
Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 12Baseline, Week 12

The Psoriasis Area and Severity Index (PASI) score (0-72, with higher score representing greater severity) is a measurement of the severity and extent of psoriasis. The four regions of the body parts are head (10%), arms (20%), trunk (30%) and legs (40%). In each region, the area is expressed as a score of 0 (nothing), 1 (1-9%), 2 (10-29%), 3 (30-49%), 4 (50-69%), 5 (70-89%) or 6 (90-100%). Within each area, the degree of severity for erythema, induration and scaling are estimated between 0 and 4, with 4 being the highest severity. The final score combines disease severity and effected body surface area (BSA) from for four regions using the formula PASI =0.1Ah(Eh + Ih + Sh) + 0.2Au(Eu + Iu + Su) + 0.3At(Et + It + St) + 0.4Al(El + Il + Sl) where A = Area Score; E = erythema; I =induration; S = scaling; h = head; u = upper limbs; t = trunk; l = lower limbs.

Secondary Outcome Measures

Absolute Psoriasis Symptom Inventory (PSI) Score at Baseline, Week 1, 2, 4, 6, 8, 10, 12, 14 and 16, Early Termination (ET), ET Follow-up Visit 1 and 2Baseline, Week 1, 2, 4, 6, 8, 10, 12, 14 and 16, ET (Prior to Week 12), ET Follow-up Visit 1 (2 weeks post ET) and 2 (4 weeks post ET)

PSI was a self-administered 8-item questionnaire that measured the severity of psoriasis symptoms over the past 24 hours and the past 7 days. PSI included following 8 items: itch, pain, burning, stinging, cracking, scaling, flaking, and redness. Each item was rated on a scale from 0 to 4, where 0= not at all severe, 1= mild, 2= moderate, 3= severe and 4= very severe. Scores from all items were summed to give PSI score range from 0 (no severity) to 32 (maximum severity), higher PSI score indicated greater severity.

Percentage of Participants With PGA Score Clear (0) or Almost Clear (1) and >=2 Points Improvement From Baseline at Week 1, 2, 4, 6, 8, 10, 14, and 16Baseline, Week 1, 2, 4, 6, 8, 10, 14, and 16

PGA of psoriasis was scored on a 5-point scale, reflecting a global consideration of the erythema, induration, and scaling across all psoriatic lesions. Average erythema, induration, and scaling were scored separately over the whole body according to a 5-point severity scale (0 \[no symptom\] to 4 \[severe symptom\]). The total score was calculated as average of the 3 severity scores and rounded to the nearest whole number score to determine the PGA score and category. Scale for PGA: 0= clear, 1= almost clear, 2= mild, 3= moderate and 4= severe. Higher scores indicate more severity.

Percentage of Participants Who Achieved PSI Score of 0 (Not at All) or 1 (Mild) on All Items at Week 1, 2, 4, 6, 8, 10, 12, 14, and 16Week 1, 2, 4, 6, 8, 10, 12, 14, and 16

Scores from all items were summed to give PSI score range from 0 (no severity) to 32 (maximum severity), higher PSI score indicated greater severity.

Number of Participants With Treatment-Emergent Adverse Events (AEs), Serious Adverse Events (SAEs), Treatment Related AEs and SAEsDay 1 of study drug dose to maximum of 4 weeks post last dose (maximum up to 16 weeks)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and all non-SAEs. Treatment emergent AEs (TEAEs) were events that occurred between first dose of study drug and up to 4 weeks after last dose that were absent before treatment or that worsened relative to pretreatment state. A treatment-related AE was any untoward medical occurrence attributed to the study drug in a participant who received study drug. Relatedness to study drug was assessed by the investigator.

Number of Participants With TEAEs by SeverityDay 1 of study drug dose to maximum of 4 weeks post last dose (maximum up to 16 weeks)

An AE was any untoward medical occurrence in a participant who received investigational product without regard to possibility of causal relationship. AE was assessed according to severity; mild (not causing any significant problem, dose adjustment not required), moderate (caused problem that does not interfere significantly with usual activities or the clinical status, dose adjustment needed due to adverse event) and severe (caused problem that interfered significantly with usual activities or the clinical status, study drug stopped due to adverse event).

Number of Participants Who Discontinued From Study Due to Adverse EventsDay 1 of study drug dose to maximum of 4 weeks post last dose (maximum up to 16 weeks)
