Opportunistic infections are infections caused by uncommon pathogens (eg, pneumocystis jirovecii, cryptococcosis) or unusually severe infections caused by common pathogens (eg, cytomegalovirus, herpes zoster) Study participant has a history of a positive tuberculosis (TB) test or evidence of possible TB or latent TB infection at the Screening Visit Study participant has concurrent acute or chronic viral hepatitis B or C or human immunodeficiency virus (HIV) infection. Study participants who have evidence of, or tested positive for hepatitis B or hepatitis C are excluded Study participant has 12-lead ECG with changes considered to be clinically significant (eg, QT interval corrected using Fridericia's formula [QTcF] >450 ms, bundle branch block, or evidence of myocardial ischemia) at the Screening Visit or on Day -1 Study participant has active neoplastic disease or history of neoplastic disease within 5 years of the Screening Visit (except for basal or squamous cell carcinoma of the skin or carcinoma in situ that has been definitively treated with standard of care) Study participants receiving any live (includes attenuated) vaccination within the 8 weeks prior to the Screening Visit (eg, inactivated influenza and pneumococcal vaccines are allowed but nasal influenza vaccination is not permitted). Live vaccines are not allowed during the study or for 20 weeks after the dose of the investigational medicinal product (IMP) Study participant has previously participated in this study or the study participant has previously been assigned to treatment in a study of the medication under investigation in this study Study participant has participated in another study of an IMP (and/or an investigational device) within the previous 90 days or 5 half-lives, whichever is longer, prior to IMP administration Study participant has made a blood donation of a blood loss of more than 400 mL of blood or blood products within 90 days prior to admission (Day -1) or plans to donate blood during the study Study participant has a positive test result for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in real-time reverse transcriptase polymerase chain reaction (RT-PCR) on the admission sample Study participant has clinical signs and symptoms consistent with coronavirus disease 2019 (COVID-19), eg fever, dry cough, dyspnea, sore throat, fatigue, or confirmed infection by appropriate laboratory test within the previous 14 days prior to Screening or on admission Study participant who had severe course of COVID-19 (ie, hospitalization, extracorporal membrane oxygenation, mechanically ventilated)

What is the study measuring?
-----------------
Primary Outcome Measures

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

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of participants with at least one treatment-emergent adverse event (TEAE) from Baseline to end of Safety Follow-Up | 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. | From Baseline (Day 1) to end of Safety Follow-Up (up to Day 140) | 
| Percentage of participants with at least one treatment-emergent serious adverse event (SAE) from Baseline to end of Safety Follow-Up | 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 | From Baseline (Day 1) to end of Safety Follow-Up (up to Day 140) | 
| Apparent terminal half-life (t1/2) | 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. | From Baseline (Day 1 predose) at predefined time points (up to Day 140) | 
| Time of occurrence of the maximum observed concentration (tmax) of a single dose bimekizumab (BKZ) | tmax: time to reach maximum plasma concentration | From Baseline (Day 1 predose) at predefined time points (up to Day 140) |
