This study is designed to test the efficacy and safety of intravenous Ravulizumab in patients with ALS.

Study design

The ALXN1210-ALS-308 trial is sponsored by Alexion Pharmaceuticals and is a randomised, double-blind, placebo-controlled trial. This means that the effect of ravulizumab is tested by comparing a group of patients that receive ravulizumab to a group of patients receiving placebo. Participants will be randomly assigned to receive ravulizumab or placebo. A placebo is something that looks exactly the same as the study medicine but does not have any active medicine in it. Participants are twice as likely to be assigned to ravulizumab treatment versus placebo.The study has a randomized controlled period of 50 weeks and during this time, the participant and the research team do not know who is receiving placebo or ravulizumab. After the randomized controlled period, participants can enter the Open-label Extension Period of the study and receive ravulizumab.

Ravulizumab and placebo will be administered via an injection into the bloodstream (intravenously).
