Cohort 1

Arm Description

Subjects in this cohort will receive dose 1 every four weeks (Q4W) subcutaneously (sc) during the 48-week open-label Treatment Period. There will be an option to increase the dose to dose 2 Q4W at the discretion of the Investigator if the subject's Psoriasis Area and Severity Index (PASI) response is >=50% to <75% reduction from the Baseline of PS0016 at Week 12 or later. If the subject's disease is adequately controlled on dose 2 Q4W, they may return to dose 1 Q4W at the discretion of the Investigator.

Outcomes

Primary Outcome Measures

Incidence of Treatment Emergent Adverse Event (TEAE) Adjusted by Duration of Participant Exposure to Treatment
TEAEs were events that had a start date on or after the first administration of study treatment in PS0018 until the last received dose of investigational medicinal product (IMP) +140 days [which covered the 20-week Safety Follow-Up (SFU) Visit]. The number of TEAEs adjusted by duration of exposure to study treatment was scaled such that it provides an incidence rate per 100 patient-years. If a participant had multiple events, the time of exposure was calculated to the first occurrence of the adverse event (AE) being considered. If a participant had no events, the total time at risk was used.

Secondary Outcome Measures

Plasma Concentration of Bimekizumab During the Study
Plasma concentration of Bimekizumab was expressed in micrograms per milliliter (μg/mL). Values Below Limit of Quantification (BLQ) were replaced by value of Lower Limit of Quantification (LLOQ) divided by 2 (=0.075 μg/mL) in calculations of Means and Coefficient of Variations (CVs). Means and CVs were only calculated if at least 2/3 of the concentrations were quantified at the respective timepoint.
Percentage of Participants With Positive Anti-bimekizumab (BZK) Antibody Levels Prior to Study Treatment
For a given visit / time point, an Anti-BKZ status of positive was concluded for any participant with an anti-drug antibody (ADA) level that was above cut point (ACP) and CP at that visit/ time point. A participant was classified as overall positive if at least one PS0018 measurement is ACP and CP (this included participants who had negative results at PS0016 Baseline). Percentages were based on the number of participants with a non-missing measurement, from samples that did not contain BKZ concentration levels above the drug tolerance, at the visit. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.
Percentage of Participants With Overall Positive Anti-bimekizumab (BZK) Antibody Levels Following Study Treatment
For a given visit / time point, an Anti-BKZ status of positive was concluded for any participant with an anti-drug antibody (ADA) level that was above cut point (ACP) and CP at that visit/ time point. A participant was classified as overall positive if at least one PS0018 measurement is ACP and CP (this included participants who had negative results at PS0016 Baseline). Percentages were based on the number of participants with a non-missing measurement, from samples that did not contain BKZ concentration levels above the drug tolerance, at the visit. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.
Percentage of Participants Achieving a 50% or Higher Improvement in Psoriasis Area and Severity Index (PASI) During the Study
The PASI quantifies the severity and extent of the disease and weighs these with the percentage of body surface area (BSA) involvement. The degree of involvement is estimated across 4 body areas; head, upper limbs, trunk, and lower limbs and then transferred into a grade. The Investigator assessed the average redness, thickness, and scaliness of lesions in each body area (each on a 5 - point scale); 0 = none, 1 = slight, 2 = moderate, 3 = marked, and 4 = very marked. The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity. The PASI50 responses were based on at least 50% improvement in the PASI score at the Baseline of PS0016. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.
Percentage of Participants Achieving a 75% or Higher Improvement in Psoriasis Area and Severity Index (PASI) During the Study
The PASI quantifies the severity and extent of the disease and weighs these with the percentage of body surface area (BSA) involvement. The degree of involvement is estimated across 4 body areas; head, upper limbs, trunk, and lower limbs and then transferred into a grade. The Investigator assessed the average redness, thickness, and scaliness of lesions in each body area (each on a 5 - point scale); 0 = none, 1 = slight, 2 = moderate, 3 = marked, and 4 = very marked. The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity. The PASI75 responses were based on at least 75% improvement in the PASI score at the Baseline of PS0016. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.
Percentage of Participants Achieving a 90% or Higher Improvement in Psoriasis Area and Severity Index (PASI) During the Study
The PASI quantifies the severity and extent of the disease and weighs these with the percentage of body surface area (BSA) involvement. The degree of involvement is estimated across 4 body areas; head, upper limbs, trunk, and lower limbs and then transferred into a grade. The Investigator assessed the average redness, thickness, and scaliness of lesions in each body area (each on a 5 - point scale); 0 = none, 1 = slight, 2 = moderate, 3 = marked, and 4 = very marked. The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity. The PASI90 responses were based on at least 90% improvement in the PASI score at the Baseline of PS0016. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.
Percentage of Participants Achieving a 100% Improvement in Psoriasis Area and Severity Index (PASI) During the Study

The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity. The PASI100 responses were based on 100% improvement in the PASI score at the Baseline of PS0016.

Primary Outcome Measure Information:
Title
Incidence of Treatment Emergent Adverse Event (TEAE) Adjusted by Duration of Participant Exposure to Treatment
Description
TEAEs were events that had a start date on or after the first administration of study treatment in PS0018 until the last received dose of investigational medicinal product (IMP) +140 days [which covered the 20-week Safety Follow-Up (SFU) Visit]. The number of TEAEs adjusted by duration of exposure to study treatment was scaled such that it provides an incidence rate per 100 patient-years. If a participant had multiple events, the time of exposure was calculated to the first occurrence of the adverse event (AE) being considered. If a participant had no events, the total time at risk was used.

Title
Percentage of Participants Achieving a 50% or Higher Improvement in Psoriasis Area and Severity Index (PASI) During the Study
Description
The PASI quantifies the severity and extent of the disease and weighs these with the percentage of body surface area (BSA) involvement. The degree of involvement is estimated across 4 body areas; head, upper limbs, trunk, and lower limbs and then transferred into a grade. The Investigator assessed the average redness, thickness, and scaliness of lesions in each body area (each on a 5 - point scale); 0 = none, 1 = slight, 2 = moderate, 3 = marked, and 4 = very marked. The PASI score ranges from 0 to 72 with a higher score indicating increased disease severity. The PASI50 responses were based on at least 50% improvement in the PASI score at the Baseline of PS0016. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.
