Maintenance SC dosing will begin at Week 5 and will continue Q4W (every 4 weeks) thereafter for a total of 24 weeks of study treatment. After 24 weeks of crovalimab treatment, participants who derive benefit from the drug may continue to receive crovalimab.

  • Active Comparator: Arm B (Eculizumab)
    Participants will receive an approved maintenance dose of eculizumab starting on Day 1 and Q2W (every 2 weeks) thereafter for a total of 24 weeks of study treatment. After 24 weeks of study eculizumab treatment, participants will have the option to switch to crovalimab or to discontinue from the study after completion of 10 weeks of safety follow-up.

  • Experimental: Arm C (Crovalimab) (Exploratory)
    Participants will receive a loading series of Crovalimab comprised of an IV dose on Week 1 Day 1, followed by weekly crovalimab SC doses for 4 weeks on Week 1 (Day 2) then on Weeks 2, 3, and 4.

  • Women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception during the treatment period and for 10.5 months after the final dose of crovalimab or for 3 months after the final dose of eculizumab (or longer if required by the local product label).

Exclusion Criteria:

  • History of allogeneic bone marrow transplantation.
  • History of myelodysplastic syndrome with Revised International Prognostic Scoring System (IPSS-R) prognostic risk categories of intermediate, high and very high.
  • Pregnant or breastfeeding, or intending to become pregnant during the study, within 10.5 months after the final dose of crovalimab, or 3 months after the final dose of eculizumab (or longer if required by the local product label).
  • Participation in another interventional treatment study with an investigational agent or use of any experimental therapy within 28 days of screening or within 5 half-lives of that investigational product, whichever was greater: participants enrolled in an eculizumab or ravulizumab interventional study are eligible provided they fulfill eligibility (e.g., are willing and able to comply with the study assessments) and stop their participation in current trial before randomisation/enrolment.
  • Positive for Active Hepatitis B and C infection (HBV/HCV).
  • Concurrent disease, treatment, procedure, or surgery or abnormality in clinical laboratory tests that could interfere with the conduct of the study, may pose any additional risk for the participant, or would, in the opinion of the investigator, preclude the participant's safe participation in and completion of the study.
  • History of or ongoing cryoglobulinemia at screening.
