• Healthy as determined by medical evaluation, including medical history, physical examination, neurological examination, laboratory tests, vital signs, and ECGs, and who possess a baseline eGFR ≥ 90 mL/min/1.73 m\^2, based on MDRD equation at screening.

You may not qualify if…

• Body temperature ≥38.0°Celcius at screening or check-in or history of febrile illness or other evidence of infection, systemic or otherwise, within 14 days prior to the first dose of study intervention.
• Participants with CH50 results outside the reference ranges at screening, unless approved by Alexion
• Significant blood loss or donation of blood within 3 months prior to the first dose of study intervention, donation of plasma within 30 days prior to the first dose of study intervention, receipt of blood products within 6 months prior to first dose of study intervention, or receipt of a vaccine within 30 days prior to the first dose of study intervention.
• Current enrollment or past participation within the last 30 days (or 5 half-lives, whichever is longer) prior to the first dose of study intervention in the current clinical study or any other clinical study involving an investigational study intervention or any other type of medical research.
• History or presence of drug or alcohol abuse within 1 year prior to the first dose of study intervention, current tobacco user, or positive results for alcohol and/or drug screen at screening or check-in.
• Pregnant or lactating.
• Does not produce sufficient urine output to permit urine sampling at screening and/or check-in or has a history of urinary incontinence prior to check-in.
• History of kidney transplant or actively on a transplant waiting list prior to check-in.
