About

Brief Summary

Main Inclusion Criteria:

Adult patients with evidence of active thrombotic microangiopathy (TMA), including thrombocytopenia, evidence of hemolysis, and acute kidney injury
Vaccinations against Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae infections are required prior to the start of study treatment. If the patient has not been previously vaccinated, or if a booster is required, vaccine should be given according to local regulations, at least 2 weeks prior to first study drug administration. If study treatment has to start earlier than 2 weeks post vaccination or before vaccination is given, prophylactic antibiotic treatment must be administered at the start of study treatment and for at least 2 weeks after vaccination

Main Exclusion Criteria:

Treatment with complement inhibitors, including anti-C5 antibody
ADAMTS13 deficiency (<10% activity or <0.1U/ml), and/or Shiga toxin-related hemolytic uremic syndrome (STx-HUS), and/or Positive direct Coombs test
Identified drug exposure-related HUS or HUS related to known genetic defects of cobalamin C metabolism or known diacylglycerol kinase ε (DGKE) mediated aHUS
Receiving PE/PI, for 14 days or longer, prior to the start of screening for the current TMA
Bone marrow transplantation (BMT)/hematopoietic stem cell transplantation (HSCT), heart, lung, small bowel, pancreas, or liver transplantation
Patients with sepsis or active severe systemic bacterial, viral (including COVID-19) or fungal infection, systemic infection which confounds an accurate diagnosis of aHUS or impedes the ability to manage the aHUS disease, active infection (or history of recurrent invasive infections) caused by encapsulated bacteria
Kidney disease suggestive of other disease than aHUS or of chronic kidney failure or family history of non-complement mediated genetic kidney disease
Liver disease or liver injury at screening
Systemic sclerosis (scleroderma), systemic lupus erythematosus (SLE), or antiphospholipid antibody positivity or syndrome
Chronic hemo- or peritoneal dialysis
