Exclusion Criteria:

• Study participant has any medical (acute or chronic) or psychiatric condition that, in the opinion of the Investigator, could jeopardize or would compromise the study participant's ability to participate in this study

• History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrinological, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the IMP; or interfering with the interpretation of data

• Study participant has a known hypersensitivity to any components of the investigational medicinal product (IMP) as stated in this protocol or participant has a history of moderate to severe allergic reaction to medication(s), including biologics

• Study participant has any clinically relevant abnormal findings in physical examination, laboratory tests, vital signs, or electrocardiogram (ECG), which, in the opinion of the Investigator, may place the participant at risk because of participation in the study

• Study participant has had major surgery (including joint surgery) within 6 months prior to the Screening Period, or has planned surgery within 6 months after IMP

• Study participant has current diagnosis or history of wound healing complications

• Study participant has a history of alcohol and/or drug abuse up to 6 months before the Screening Period

• Study participant has active neoplastic disease or history of neoplastic disease within 5 years of the Screening Period

• Study participant has an active infection during the Screening Period

• Study participant has clinical signs and symptoms consistent with coronavirus disease (COVID-19) or had a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test result within the last 4 weeks prior to the Screening Period or on admission

• Study participant has had a severe course of COVID-19 that required hospitalization

• Study participant has received any prescription or nonprescription medicines, including over the counter (OTC) remedies or herbal and dietary supplements, within 14 days or 5 half-lives of the respective drug, whichever is longer, other than the occasional use of analgesics, such as paracetamol (acetaminophen) or ibuprofen, oral contraceptives, or inhaled corticosteroids for seasonal rhinitis

• Study participant has received treatment with biologic agents (such as monoclonal antibodies (mAbs) including marketed drugs) within 3 months or 5 half-lives (whichever is longer) prior to dosing

• Study participant has received a vaccination within 8 weeks prior to Day 1; or intends to have a vaccination during the course of the study

• Study participant has participated in another study of a IMP (and/or an investigational device) within the previous 3 months or 5 half-lives prior to the Screening Period, whichever is longer, or is currently participating in another study of a IMP (and/or an investigational device)

• Study participant has positive serology test for hepatitis B surface antigen, hepatitis B core antibodies (both immunoglobulin G (IgG) and IgM), hepatitis C virus antibodies, or antibodies to human immunodeficiency virus type 1 and/or type 2 during the Screening Period

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidents of treatment-emergent adverse events (TEAEs) through the Safety Follow-up (SFU) Visit	A treatment-emergent adverse event (TEAE) is defined as any event not present prior to the administration of investigational medicinal product (IMP) or any unresolved event already present before administration of IMP that worsens in intensity following exposure to the treatment.	From Day 1 (Start of Treatment Period) to the end of Safety Follow-up (up to 120 days)
Primary	Maximum intensity of treatment-emergent adverse events (TEAEs) through the Safety Follow-up (SFU) Visit	Maximum intensity across all incidents of each TEAE for each study participant	From Day 1 (Start of Treatment Period) to the end of Safety Follow-up (up to 120 days)
Secondary	Maximum zampilimab serum concentration (Cmax)	Cmax: Maximum observed zampilimab serum concentration	From Day 1 (Start of Treatment Period) to the end of Safety Follow-up (up to 120 days)
Secondary	Time to maximum zampilimab serum concentration (tmax)	tmax: Time to maximum observed zampilimab serum concentration	From Day 1 (Start of Treatment Period) to the end of Safety Follow-up (up to 120 days)
Secondary	Area under the zampilimab serum concentration-time curve from time zero to last quantifiable concentration (AUC0-t)	AUC0-t: Area under the zampilimab serum concentration-time curve from time zero (Day 1) to the last quantifiable concentration	From Day 1 (Start of Treatment Period) at predefined time points to the last quantifiable concentration (up to 120 days)
