Incidence of Treatment Emergent Adverse Event (TEAE) adjusted by duration of participant exposure to treatment [1] | ||||||||
End point 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. The Safety Set consisted of all participants who received at least 1 dose of the study medication in PS0018.

Plasma concentration of bimekizumab during the study | ||||||||||||||||||||||||||
End point description |
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. The Pharmacokinetics Per-Protocol Set consisted of all enrolled participants who received at least 1 dose of the study medication and provided at least 1 quantifiable plasma concentration postdose in PS0018. Here, 'n' signifies participants who were evaluable at specified time points. Note: 999 was used a placeholder for the value that was not calculated (Participants had no prior BKZ treatment and thus no BKZ levels at Baseline).

End point description |
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. The Safety Set consisted of all participants who received at least 1 dose of the study medication in PS0018.

Percentage of participants achieving a 50% or higher improvement in Psoriasis Area and Severity Index (PASI) during the study | ||||||||||||||||||||||||||||||||||||
End point 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. The Full Analysis Set consisted of all enrolled participants who received at least 1 dose of the study medication and had a valid efficacy measurement for PASI at Baseline of PS0018.

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. Moderate IGA was defined as clearly distinguishable to moderate thickening; dull to bright red, clearly distinguishable to moderate thickening; moderate scaling. Severe was defined as severe thickening with hard edges; bright to deep dark red coloration; severe/coarse scaling covering almost all or all lesions. Baseline was defined as the last available value prior to the first injection of study medication in the PS0016 study. The Full Analysis Set consisted of all enrolled participants who received at least 1 dose of the study medication and have a valid efficacy measurement for PASI at Baseline of PS0018.

Reporting group description |
Participants received BKZ 160 mg Q4W sc during the 48-week Open Label Treatment Period. The Investigator could increase the dose to BKZ 320 mg Q4W if the participant's PASI response was >= 50% to < 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. Participants formed the Safety Set (SS). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Date |
Amendment |

16 Feb 2018 |
Protocol amendment 3, dated 16 Feb 2018, was implemented to make the following changes: • Revised the withdrawal criteria to provide instructions for the management of study participants with newly diagnosed inflammatory bowel disease or with inflammatory bowel disease flares during the study • Updated the study contact information. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
PS0018 has not been conducted in the European Economic Area (EEA) and therefore did not meet the criteria for the results posting on EudraCT. Nevertheless, due to data transparency reason, UCB decided to post the respective results. |
