AstraZeneca Plc is discontinuing a Phase 3 trial of Ultomiris (ravulizumab), a newly acquired antibody therapy being investigated in amyotrophic lateral sclerosis, due to lack of efficacy. The decision was taken following a recommendation of the trial’s independent data monitoring committee. The trial did not throw up any new safety findings, the company announced on 20 August.
