Brief summary: The purpose of the study is to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of a single subcutaneous (SC) dose of rozanolixizumab administered to healthy participants by manual push (MP) versus (vs) syringe driver.


Eligibility criteria: Inclusion Criteria:

* Study participant must be 18 to 65 years of age, inclusive
* Study participants who are overtly healthy in the opinion of the investigator as determined by medical evaluation including medical history, a general clinical examination, including physical examination and laboratory tests, and cardiac monitoring
* Study participant has blood pressure (BP) and pulse within normal range in a supine position after 5 minutes of rest (systolic BP: 90 to 140 mmHg, diastolic BP: 50 to 90 mmHg, pulse: 40 to 90 beats per minute (bpm))
* Study participant has clinical laboratory test results within the reference ranges of the testing laboratory or not clinically significant if outside the specified ranges, in the opinion of the investigator
* Study participant's electrocardiogram (ECG) is considered "normal" or "abnormal but clinically nonsignificant" (as interpreted by the investigator)
* Study participants may be male or female
* Participant has a body mass index of 18 to 32 kg/m\^2, with a minimum body weight of 35 kg

Exclusion Criteria:

* History or presence of/significant history of or current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrinological, hematological, or neurological disorders. Has active neoplastic disease or history of neoplastic disease within the previous 5 years of entry in the clinical study (except for basal or squamous cell carcinoma of the skin or carcinoma in situ that has been definitively treated with standard of care approaches). Has a history of a major organ transplant or hematopoietic stem cell/marrow transplant
* Symptomatic herpes zoster within 3 months prior to Screening
* Allergies to humanized monoclonal antibodies

* Predicted inability to comply with being free of caffeine and ethanol from 72 hours prior to clinic admission and during the In-Clinic Period of the study
* Known hypersensitivity to oral paracetamol (acetaminophen)
* History of known inflammatory bowel disease, active diverticular disease, or a history of confirmed duodenal, gastric, or esophageal ulceration in the previous 6 months
* History of hyperprolinemia, since L-proline is a constituent of rozanolixizumab.
* Twelve-lead ECG with abnormalities considered to be clinically significant upon medical review
* Renal impairment, defined as a creatinine concentration in serum of ≥1.4 mg/dL (≥123 μmol/L) for female participants and ≥1.5 mg/dL (≥132 μmol/L) for male participants
* Known viral hepatitis (B and C) or human immunodeficiency virus 1/2 antibodies or has a past medical history or family history of primary immunodeficiency or antibodies to human immunodeficiency virus type 1 and/or type 2 at Screening
* Participant has a positive test result for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in reverse transcriptase-polymerase chain reaction on admission to the unit
* Participant has clinical signs and symptoms consistent with SARS-CoV-2 (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
* Participant has active infection or is symptomatic with SARS-CoV-2 or is currently in quarantine (has been in contact with a SARS-CoV-2 positive individual in the last 14 days)
* Participant has had a severe course of SARS-CoV-2 (eg, requiring extracorporeal membrane oxygenation, mechanical ventilation, or hospitalization)
* Past or intended use of over-the-counter or prescription medication (including herbal medications) within 14 days prior to dosing until Day 57
