What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Achieving a 90% or Higher Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 12	The PASI90 response assessments are based on at least 90% improvement in the PASI score from Baseline. This is a scoring system that averages the redness, thickness, and scaliness of the psoriatic lesions (on a 0-4 scale), and weights the resulting score by the area of skin involved. Body divided into 4 areas: head, arms, trunk to groin, and legs to top of buttocks. Assignment of an average score for the redness, thickness, and scaling for each of the 4 body areas with a score of 0 (clear) to 4 (very marked). Determining the percentage of skin covered with PSO for each of the body areas and converting to a 0 to 6 scale. Final PASI= average redness, thickness, and scaliness of the psoriatic skin lesions, multiplied by the involved psoriasis area score of the respective section, and weighted by the percentage of the person's affected skin for the respective section. The minimum possible PASI score is 0= no disease, the maximum score is 72= maximal disease.	Week 12

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Investigator's Global Assessment (IGA) (Clear or Almost Clear With at Least 2 Category Improvement From Baseline) Response at Week 12	The Investigator's Global Assessment (IGA) measures the overall psoriasis severity following a 5-point scale (0-4), where scale 0= clear, no signs of psoriasis; presence of post-inflammatory hyperpigmentation, scale 1= almost clear, no thickening; normal to pink coloration; no to minimal focal scaling, scale 2= mild thickening, pink to light red coloration and predominately fine scaling, 3= moderate, clearly distinguishable to moderate thickening; dull to bright red, clearly distinguishable to moderate thickening; moderate scaling and 4= severe thickening with hard edges; bright to deep dark red coloration; severe/coarse scaling covering almost all or all lesions.	Week 12
Percentage of Participants With Investigator's Global Assessment (IGA) (Clear or Almost Clear With at Least 2 Category Improvement From Baseline) Response at Week 8	The Investigator's Global Assessment (IGA) measures the overall psoriasis severity following a 5-point scale (0-4), where scale 0= clear, no signs of psoriasis; presence of post-inflammatory hyperpigmentation, scale 1= almost clear, no thickening; normal to pink coloration; no to minimal focal scaling, scale 2= mild thickening, pink to light red coloration and predominately fine scaling, 3= moderate, clearly distinguishable to moderate thickening; dull to bright red, clearly distinguishable to moderate thickening; moderate scaling and 4= severe thickening with hard edges; bright to deep dark red coloration; severe/coarse scaling covering almost all or all lesions.	Week 8
Percentage of Participants Achieving a 90% or Higher Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 8	The PASI90 response assessments are based on at least 90% improvement in the PASI score from Baseline. This is a scoring system that averages the redness, thickness, and scaliness of the psoriatic lesions (on a 0-4 scale), and weights the resulting score by the area of skin involved. Body divided into 4 areas: head, arms, trunk to groin, and legs to top of buttocks. Assignment of an average score for the redness, thickness, and scaling for each of the 4 body areas with a score of 0 (clear) to 4 (very marked). Determining the percentage of skin covered with PSO for each of the body areas and converting to a 0 to 6 scale. Final PASI= average redness, thickness, and scaliness of the psoriatic skin lesions, multiplied by the involved psoriasis area score of the respective section, and weighted by the percentage of the person's affected skin for the respective section. The minimum possible PASI score is 0= no disease, the maximum score is 72= maximal disease.	Week 8
Percentage of Participants Achieving a 75% or Higher Improvement in Psoriasis Area and Severity Index (PASI) Score at Week 12	The PASI75 response assessments are based on at least 75% improvement in the PASI score from Baseline. This is a scoring system that averages the redness, thickness, and scaliness of the psoriatic lesions (on a 0-4 scale), and weights the resulting score by the area of skin involved. Body divided into 4 areas: head, arms, trunk to groin, and legs to top of buttocks. Assignment of an average score for the redness, thickness, and scaling for each of the 4 body areas with a score of 0 (clear) to 4 (very marked). Determining the percentage of skin covered with PSO for each of the body areas and converting to a 0 to 6 scale. Final PASI= average redness, thickness, and scaliness of the psoriatic skin lesions, multiplied by the involved psoriasis area score of the respective section, and weighted by the percentage of the person's affected skin for the respective section. The minimum possible PASI score is 0= no disease, the maximum score is 72= maximal disease.	Week 12
Percentage of Participants Achieving a 100% Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 12	PASI correlates to the physician's assessment of psoriasis symptoms including redness of lesions, thickness of lesions, scaliness of lesions and extent of disease. Each parameter is graded from 0-4, 0 refers to no disease and 4 to severe involvement. The body is divided into 4 areas for scoring (head, arms, trunk to groin, legs to top of buttocks), and the final score ranges from 0-72. The PASI 100 response rate at Week 12 is measured as the percentage of participants who achieved 100% improvement from baseline PASI at Week 12.	Week 12
Plasma Concentrations of Bimekizumab During the Study	Bimekizumab plasma concentration was expressed in micrograms per milliliter (μg/mL). Values Below Limit of Quantification (BLQ) were replaced by the value of lower limit of quantification (LLOQ) divided by 2 = 0.075 μg/mL in the calculations of geometric mean and confidence intervals (CIs). Geometric mean was only calculated if at least two-thirds of the concentrations were quantified at the respective time point.

Population PK (Apparent Total Clearance (CL/F)) of Bimekizumab	The data were presented as population estimates of CL/F. Given the sparse nature of PK sampling, CL/F cannot be estimated for each treatment group. It was prespecified in the data analysis plan to combine doses to perform Population PK and PK/PD analysis based on a prior determination that the PK parameters are not dose-dependent.	From Baseline (Week 0) until Safety Follow-Up Visit (20 weeks after the last dose; Up to Week 28)
Population PK (Apparent Volume of Distribution (V/F)) of Bimekizumab	The data were presented as population estimates of V/F.

It was prespecified in the data analysis plan to combine doses to perform Population PK and PK/PD analysis based on a prior determination that the PK parameters are not dose-dependent.	From Baseline (Week 0) until Safety Follow-Up Visit (20 weeks after the last dose; Up to Week 28)
Concentration of Bimekizumab Leading to 50% of Maximum Effect (EC50)	The data were presented as population estimates of EC50. EC50 was estimated based on all available data and cannot be derived for each treatment arm. It was prespecified in the data analysis plan to combine doses to perform Population PK and PK/PD analysis based on a prior determination that the PK parameters are not dose-dependent.
