Outcome Measures

Primary Outcomes (14)

  • Change From Baseline in Psoriasis Area and Severity Index (PASI) at Week 28

    The PASI is the most commonly used and validated assessment for grading the severity of psoriasis in clinical studies. The PASI quantifies the severity and extent of the disease and weighs these with the percentage of body surface area (BSA) involvement. The percent area of involvement (BSA%) is estimated across 4 body areas; head (10%), upper limbs (20%), trunk (30%), and lower limbs (40%) and then transferred into a grade. The Investigator assesses 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.

    From Baseline to Week 28

  • Plasma Concentration of Bimekizumab at Baseline

    Plasma concentration was expressed as geometric mean concentrations (GMCs) and measured in micrograms per milliliter (μg/mL). Note: Means, Lower confidence interval (LCI), Upper confidence interval (UCI) are only calculated if at least 2/3 of the concentrations were quantified at the respective time point. Values below limit of quantification (BLQ) are replaced by value of lower limit of quantification (LLOQ)/2 (=0.075ug/mL) in calculations of means.

  • Percentage of Participants Reporting Positive Anti-Drug-Antibodies (ADA) Titre Prior to Study Treatment With Bimekizumab at Baseline

    An ADA status of positive was concluded for any participant with an ADA level that was above cut point (ACP) and 'confirmed positive' (CP) at any time point. A participant was classified as having treatment-induced ADA positivity when meeting one of the following criteria: -The Baseline result was either below cut point (BCP) or ACP and 'not confirmed positive' (NCP), and at least 1 post Baseline time point was ACP and CP. -The Baseline result was positive (ACP and CP) and at least one post-Baseline measurement showed a pre-defined fold increase in titre from the Baseline value. Note: The overall status of a participant is 'Positive' if at any post-Baseline visit the result was ACP and confirmed positive.
