A Bioequivalence Study of Bimekizumab Given as 1x2mL or 2x1mL Subcutaneous Injection Using an Autoinjector in Healthy Study Participants

Exclusion Criteria

• •Study participant has a known hypersensitivity to any components of the bimekizumab (and/or an investigational device) as stated in this protocol
• •Study participant has an active infection or history of infections as follows:
• •Any active infection (except common cold) within 14 days prior to Screening Visit
• •A serious infection, defined as requiring hospitalization or iv anti-infectives within 2 months prior to the Screening Visit
• •A history of opportunistic, recurrent, or chronic infections that, in the opinion of the Investigator, might cause this study to be detrimental to the study participant. 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 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 last dose of the investigational medicinal product (IMP)
• •Study participant has previously participated in this study or a study participant has previously been assigned to bimekuzimab treatment in any other study
• •Exposure to 3 or more new chemical entities within 12 months prior to dosing
• •Current enrollment or past participation within the last 30 days before signing the informed consent form (ICF) in any other clinical study involving an investigational study intervention or any other type of medical research
• •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 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 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
