入选标准

  • Vaccination against Neisseria meningitidis < 3 years prior to initiation of study treatment in accordance with current local guidelines or standard of care, as applicable in patients with complement deficiency (for ALL cohorts)
  • For female patients of childbearing potential, an agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception (for ALL cohorts)
  • Onset of initial TMA presentation, within 28 days prior to the first dose of crovalimab (For naïve cohort only)
  • Clinical evidence of response to either eculizumab or ravulizumab, as documented by a platelet count ≥LLN, LDH ≤ULN, and stable (decrease or increase of ≤20%) or improving creatinine at two consecutive measurements at least 4 weeks apart prior to Week 1 Day 1 of crovalimab treatment. (For switch cohort only)
  • Known C5 polymorphism (e.g., Arg885) (For C5SNP cohort only)

排除标准

  • TMA associated with non-aHUS-related renal disease
  • History of a kidney disease other than aHUS, affecting renal function
  • Known systemic sclerosis (scleroderma), systemic lupus erythematosus, or antiphospholipid antibody positivity or syndrome
  • Active systemic bacterial, viral, or fungal infection within 14 days before first crovalimab administration
  • History of Neisseria meningitidis infection within 6 months of study enrollment
  • History of malignancy within 5 years prior to screening and up to the first crovalimab administration
