Ultomiris rekommenderas för godkännande i EU av CHMP för behandling av vuxna med generell myasthenia gravis

Ultomiris (ravulizumab) har fått en positiv rekommendation för marknadsgodkännande av CHMP som ett tillägg till standard therapy för behandlingen av vuxna patienter med generel myasthenia gravis (gMG) som är anti-acetylcholine receptor (AChR) antibody-positive. Vid godkännandet blir Ultomiris den första långverkande C5 complement hämmaren i EU.

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency based its positive opinion on results from the CHAMPION-MG Phase III trial.

In this trial, Ultomiris was superior to placebo in the primary endpoint of change from baseline in the Myasthenia Gravis-Activities of Daily Living Profile (MG-ADL) total score at Week 26, a patient-reported scale that assesses patients’ abilities to perform daily activities.1

gMG is a rare, debilitating, chronic, autoimmune neuromuscular disease that leads to a loss of muscle function and severe weakness.2 The diagnosed prevalence of gMG in the EU is estimated at approximately 89,000.3-9

Renato Mantegazza, Professor at the Department of Neuroimmunology and Neuromuscular Diseases, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy, and CHAMPION-MG trial investigator, said: “gMG is a rare and complex disorder that requires early, consistent and reliable intervention. This positive recommendation offers hope to the community for an effective long-acting option that will require fewer treatments each year and help improve disease management.”

Marc Dunoyer, Chief Executive Officer, Alexion, said: “This recommendation is a major milestone in our commitment to help a broader range of gMG patients, including those with milder symptoms, and expand access to Ultomiris. As we listen to the patient community, we’re focused on understanding and meeting the needs of gMG patients, providing them with effective and accessible treatment options, and the positive opinion is a great step forward.”

In CHAMPION-MG, the safety profile of Ultomiris was comparable to placebo and consistent with that observed in Phase III trials of Ultomiris in paroxysmal nocturnal haemoglobinuria (PNH) and atypical haemolytic uraemic syndrome (aHUS). The most common adverse drug reactions are diarrhoea, upper respiratory tract infection, nasopharyngitis and headache.1

The CHMP recommended approval as an add-on to standard therapy for the treatment of adult patients with gMG who are AChR antibody-positive.

Ultomiris was approved in the US for adults with gMG who are AChR antibody-positive in April 2022, and regulatory reviews are ongoing in additional countries, including Japan.
