Primary

MeasureTime frameDescription
Incidence of Treatment Emergent Adverse Event (TEAE) Adjusted by Duration of Participant Exposure to TreatmentFrom Baseline (Week 0) until Safety Follow Up Visit (up to Week 64)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

MeasureTime frameDescription
Percentage of Participants With Positive Anti-bimekizumab (BZK) Antibody Levels Prior to Study TreatmentBaseline of study PS0016 [NCT03025542]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 StudyFrom Baseline of study PS0016 [NCT03025542] until Safety Follow Up Visit (up to Week 64) of study PS0018The 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.

Participants received bimekizumab (BKZ) 160 milligrams (mg) every 4 weeks (Q4W) subcutaneously (sc) during the 48-week Open Label Treatment Period. The Investigator could increase the dose to BKZ 320 mg Q4W if the participant's Psoriasis Area and Severity Index (PASI) response was greater than or equal to (\>=) 50% to less than (\<) 75% reduction from the Baseline of PS0016 at Week 12 or later. If the participant's disease was adequately controlled on BKZ 320 mg Q4W, they could return to BKZ 160 mg Q4W at the discretion of the Investigator.

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.

Time frame: From Baseline (Week 0) until Safety Follow Up Visit (up to Week 64)

Population: The Safety Set consisted of all participants who received at least 1 dose of the study medication in PS0018.

Percentage of Participants Achieving a 100% 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 PASI100 responses were based on 100% 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 Who Shifted From Moderate Investigator´s Global Assessment (IGA) Score at PS0016 [NCT03025542] Baseline to Almost Clear IGA Score During the Study

A static IGA for Psoriasis (PSO) was used to assess disease severity in all study participants during the study. IGA is a 5 point scale ranging from 0 = Clear to 4 = Severe.

Percentage of Participants Who Shifted From Severe Investigator´s Global Assessment (IGA) Score at PS0016 [NCT03025542] Baseline to Moderate IGA Score During the Study

A static IGA for Psoriasis (PSO) was used to assess disease severity in all study participants during the study. IGA is a 5 point scale ranging from 0 = Clear to 4 = Severe. Severe IGA was defined as severe thickening with hard edges; bright to deep dark red coloration; severe/coarse scaling covering almost all or all lesions. Moderate was defined as clearly distinguishable to moderate thickening; dull to bright red, clearly distinguishable to moderate thickening; moderate scaling. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study.

A static IGA for Psoriasis (PSO) was used to assess disease severity in all study participants during the study. IGA is a 5 point scale ranging from 0=Clear to 4=Severe. The response was defined as clear \[0\] or almost clear \[1\] with at least 2 category improvement from PS0016 Baseline. Clear was defined as no signs of PSO; post-inflammatory hyperpigmentation may be present. Almost clear was defined as no thickening; normal to pink coloration; no to minimal focal scaling. 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.

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.
