Study Summary

This trial will study whether a new drug, ravulizumab, is effective and safe for treating a condition called HSCT-TMA. The trial will have two stages: in the first stage, participants will receive the drug to see what dose works best; in the second stage, participants will be randomly assigned to receive either the drug or a placebo, and the effects of the drug will be compared to the placebo. The trial will last for 52 weeks total, with 26 weeks of treatment and 26 weeks of follow-up.
