Percentage of Participants With a ≥90% Improvement in Psoriasis Area and Severity Index (PASI 90) From Baseline
Tijdsspanne: Week 12
|
The PASI combines the extent of body surface involvement in 4 anatomical regions (head, trunk, arms, and legs).
For each region the percent area of skin involved was estimated from 0 (0%) to 6 (90%-100%) and severity was estimated by clinical signs of erythema, induration and scaling with a scores range from 0 (no involvement) to 4 (severe involvement).
Each area is scored by itself and the scores were then combined for the final PASI.
Final PASI calculated as: sum of severity parameters for each region * area score * weighing factor [head (0.1), upper limbs (0.2), trunk (0.3), lower limbs (0.4)].
Overall scores range from 0 (no Ps) to 72 (the most severe disease).

Change From Baseline in Percent Body Surface Area (BSA) Affected by Psoriasis
Tijdsspanne: Baseline, Week 12
|
The percentage involvement of psoriasis on each participant's body surface area was assessed by the investigator on a scale from 0% (no involvement) to 100% (full involvement), in which 1% corresponds to the size of the participant's hand including palm, fingers and thumb. ANCOVA model with modified baseline observation carried forward (mBOCF) was used to produce Least Square (LS) mean with baseline, treatment group, region weight group as fixed effects. |

Change From Baseline in Psoriasis Scalp Severity Index (PSSI) Total Score
Tijdsspanne: Baseline, Week 12
|
The PSSI is a physician assessment of erythema, induration and desquamation and percent of scalp that is covered with a scores range from 0 (none) to 4 (very severe). The composite score is derived from the sum of scores for erythema, induration, and desquamation multiplied by the score recorded for the extent of the scalp area involved, 1 (<10%) to 6 (90%-100%) with a total score ranging from 0 (less severity) to 72 (more severity). ANCOVA model with mBOCF was used to produce LS mean with baseline, treatment group, region weight group as fixed effects. |

Change From Baseline in Nail Psoriasis Severity Index (NAPSI) Total Score
Tijdsspanne: Baseline, Week 12
|
NAPSI is a numeric, reproducible, objective tool for evaluation of fingernail(fn) Ps. This scale is used to evaluate severity of fn bed Ps & fn matrix Ps by area of involvement in the fn unit. fn is divided with imaginary horizontal & longitudinal lines into quadrants. Each fn is given a score for fn bed Ps 0(none) to 4(Ps in 4 quadrants of the fn) & fn matrix Ps 0(none) to 4(Ps in 4 quadrants in matrix), depending on presence (score of 1) or absence (score of 0) of any of the features of fn bed or matrix Ps in each quadrant.NAPSI score of a fn is sum of scores in fn bed & fn matrix from each quadrant (maximum of 8). Each fn is evaluated, then the sum of all fn equals the total NAPSI score with a range from range 0 to 80. Higher scores indicate more severe ps. ANCOVA model with mBOCF was used to produce LS mean with baseline, treatment group, region weight group as fixed effects. |

Change From Baseline in European Quality of Life - 5 Dimensions 5 Level (EQ-5D 5L) "Bolt On" Psoriasis (PSO) -Index
Tijdsspanne: Baseline, Week 12
|
The European Quality of Life - 5 Dimensions 5 Level (EQ-5D-5L) is a standardized measure of health status used to provide a simple, generic measure of health for clinical and economic appraisal. The EQ-5D-5L consists of a descriptive system of the respondent's health which comprises the following 5 dimensions: 1) mobility 2) self-care 3) usual activities 4) pain/discomfort 5) anxiety/depression. The Bolt On PSO is an addition to the EQ-5D-5L that consists of 2 dimensions specific to psoriatic disease: 6) skin irritation (itching) and 7) self-confidence. Index scores for the Bolt On PSO range from 0.0042 to 1.0 (worse to better health). ANCOVA model was used to produce LS mean with baseline, treatment group, region weight group as fixed effects. |

Tijdsspanne: Baseline, Week 12
|
The EQ-5D-5L descriptive system comprises 5 dimensions, each with 5 levels. The EQ-5D-5L health states were converted into a single summary index by applying a crosswalk using a UK Population value set to each of the levels in each dimension. This produced patient-level index scores between -0.594 and 1.0 (worse to better health). ANCOVA model with mBOCF was used to produce LS mean with baseline, treatment group, region weight group as fixed effects. |
