* Treatment of any infection with IV (within 30 days of Screening) or oral (within 14 days of Screening) antibacterials, antivirals, or antifungals.
* History of clinically significant hematologic or bone marrow disease or blood dyscrasias.
* History of meningococcal infection.
* History of tuberculosis.
* History of asplenia (functional or anatomical).
* Prior exposure to KP104.
* Known allergy to penicillin antibiotics or history of allergy or contraindication to required prophylactic antibiotic therapy to be used during the study.
* Known or suspected complement deficiency during screening.
* Positive serology for Hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV) at Screening.
