Trial Details


Cemdisiran is a drug that targets C5 in certain cells.
Pozelimab and ravulizumab are monoclonal antibodies that target C5 in certain cells. 

In this trial, you’ll be randomized to 1 of 2 groups. Once you’re randomized, you’ll be told what group you’re in:
  • Group 1 – Cemdisiran and pozelimab
  • Group 2 – Ravulizumab

Randomized means doctors will use a computer to assign you to either group. A computer assigns you by chance, like flipping a coin or drawing a name out of a hat. You, your doctor or the clinical trial doctor won’t have any control over which group you’ll be assigned. This means you won’t be able to choose your group.
 
You’ll get: 
  • Cemdisiran – Group 1 only - Given as a shot under your skin
  • Pozelimab– Group 1 only - Given as intravenous (IV) infusions and as a shot under your skin
  • Ravulizumab - Group 2 only - Given as IV infusions

You may continue treatment for 6 months. have blood tests to see how well the treatment is working. The clinical trial doctors will check your health for about 1 year.
