Outcome Measures

Primary Outcome Measures

Area under the plasma concentration-time curve from time zero to infinity (AUC) for a single dose bimekizumab (BKZ) [Baseline (Day 1 predose) at predefined time points (up to Day 140)]
AUC: Area under the bimekizumab plasma concentration-time curve from time 0 (Day 1 predose) to infinity
Area under the plasma concentration-time curve from time zero to last quantifiable concentration (AUC0-t) for a single dose bimekizumab (BKZ) [From Baseline (Day 1 predose) at predefined time points to the last quantifiable concentration (Day 140)]
AUC0-t: Area under the bimekizumab plasma concentration-time curve from time zero (Day 1 predose) to the last quantifiable concentration
Maximum plasma concentration (Cmax) for a single dose bimekizumab (BKZ) [From Baseline (Day 1 predose) at predefined time points (up to Day 140)]
Cmax: Maximum observed plasma concentration

Secondary Outcome Measures

Percentage of participants with at least one treatment-emergent adverse event (TEAE) from Baseline to end of Safety Follow-Up [From Baseline (Day 1) to end of Safety Follow-Up (up to Day 140)]
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
Percentage of participants with at least one treatment-emergent serious adverse event (SAE) from Baseline to end of Safety Follow-Up [From Baseline (Day 1) to end of Safety Follow-Up (up to Day 140)]
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: Results in death Is life-threatening Requires in patient hospitalization or prolongation of existing hospitalization Is a congenital anomaly or birth defect Is an infection that requires treatment parenteral antibiotics Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above
Apparent terminal half-life (t1/2) [From Baseline (Day 1 predose) at predefined time points (up to Day 140)]
Apparent terminal half-life, reported in units of days, as determined via simple linear regression (slope=-lambdaz) of natural log (ln) concentration versus time for data points in the terminal phase of the concentration-time curve. t1/2 is calculated as ln2/lambdaz.
Time of occurrence of the maximum observed concentration (tmax) of a single dose bimekizumab (BKZ) [From Baseline (Day 1 predose) at predefined time points (up to Day 140)]
tmax: time to reach maximum plasma concentration
