  • History of primary immunodeficiency or a hereditary deficiency of the complement system.
  • Central nervous system (CNS) disease .
  • Diagnosis or history of malignant disease within 5 years prior to Screening.

Lab values

  • Inadequate clinical laboratory parameters at Screening.
  • Rapidly progressing glomerulonephritis with eGFR reduction ≥50% within 12 weeks of Screening.

Other
