Alexion aims to advance NMOSD treatment landscape with exceptional Ultomiris efficacy data at ECTRIMS 2022

Alexion, AstraZeneca Rare Disease, will present new data showing significant advances for the treatment of anti-aquaporin-4 (AQP4) antibody-positive (Ab+) neuromyelitis optica spectrum disorder (NMOSD) at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) Congress, 26 to 28 October 2022.

Data presented at the meeting will feature new insights from Alexion’s complement portfolio illustrating the critical role of C5 inhibition in treating AQP4 Ab+ NMOSD and significantly reducing the risk of relapses, including findings on the first and only long-acting C5 complement inhibitor, Ultomiris (ravulizumab).

Marc Dunoyer, Chief Executive Officer, Alexion, said: “NMOSD relapses are unpredictable and often cause permanent disability, including blindness, paralysis and even premature death. Our data build on the established role of complement inhibition in managing NMOSD and reinforce our commitment to patient-centred innovation. Results from the CHAMPION-NMOSD trial highlight the potential for Ultomiris to substantially reduce the risk of relapse and ease treatment burden for the community.”

Redefining NMOSD disease management
An oral presentation will showcase results of the CHAMPION-NMOSD trial, which evaluated the safety and efficacy of Ultomiris in adults with AQP4 Ab+ NMOSD, compared to the external placebo arm from the pivotal Soliris PREVENT clinical trial.

The data will show there were zero adjudicated on-trial relapses observed in patients with AQP4 Ab+ NMOSD with a median treatment duration of 73 weeks, representing a relapse risk reduction of 98.6% (pUltomiris in the CHAMPION-NMOSD trial were consistent with previous clinical studies and other approved indications.

Improving understanding of the NMOSD patient experience
Two poster presentations detail findings from qualitative interviews with NMOSD patients. This work helps to inform the scientific community about the immediate and lasting impact of relapses, including ability to work and participate in daily activities, mobility and pain as well as reliance on caregiver support.
