Ultomiris transforms the treatment landscape for AQP4 Ab+ NMOSD patients, with
potential to eliminate relapses and improve outcomes
LONDON, UK I May 10, 2023 I Ultomiris (ravulizumab) has been approved in the European Union (EU) as the first and only long-acting C5 complement inhibitor for the treatment of adult patients with anti-aquaporin-4 (AQP4) antibody-positive (Ab+) neuromyelitis optica spectrum disorder (NMOSD).1
The approval by the European Commission follows the positive opinion of the Committee for Medicinal Products for Human Use and is based on results from the CHAMPION-NMOSD Phase III trial, which were published online in the Annals of Neurology and selected as an abstract of distinction at the 2023 American Academy of Neurology Annual Meeting.2 In the trial, Ultomiris was compared to an external placebo arm from the pivotal Soliris PREVENT clinical trial.
Ultomiris met the primary endpoint of time to first on-trial relapse as confirmed by an independent adjudication committee. Zero relapses were observed among Ultomiris patients with a median treatment duration of 73 weeks (relapse risk reduction: 98.6%, hazard ratio (95% CI): 0.014 (0.000, 0.103), p<0.0001) and continuing through a median duration of 90 weeks.2
NMOSD is a rare and debilitating autoimmune disease that affects the central nervous system (CNS), including the spine and optic nerves.3-5 Most people living with NMOSD experience unpredictable relapses, characterised by a new onset of neurologic symptoms or worsening of existing neurologic symptoms, which tend to be severe and recurrent and may result in permanent disability.6-8 The diagnosed prevalence of adults with NMOSD in the EU is estimated at approximately 5,000.9
Orhan Aktas, MD, Professor at the Department of Neurology, Medical Faculty at Heinrich-Heine-University, Düsseldorf, Germany, said: “Effective NMOSD management hinges on reducing relapses – even a single relapse may cause irreversible disabilities leaving patients unable to move, speak or care for themselves. This approval in Europe will offer patients and physicians a new, long-acting treatment with unmatched relapse risk reduction, as Ultomiris showed zero relapses in its pivotal trial with dosing every eight weeks.”
Marc Dunoyer, Chief Executive Officer, Alexion, said: “Just four years since delivering the first approved NMOSD treatment to the EU, we are pleased to once again advance the treatment landscape with Ultomiris, which may eliminate relapses for people impacted by NMOSD. This approval is the culmination of extensive work and collaboration with the NMOSD community, including patients, caregivers and healthcare providers who participated in the CHAMPION-NMOSD trial, and we’re proud to continue improving access to our innovative medicines worldwide.”
Overall, the safety and tolerability of Ultomiris in the CHAMPION-NMOSD trial were consistent with previous clinical studies and real-world use, and no new safety signals were observed. The most common adverse events (AEs) were COVID-19, headache, back pain, arthralgia and urinary tract infection. All cases of COVID-19 were non-serious and considered to be unrelated to Ultomiris.2
Regulatory submissions for Ultomiris for the treatment of NMOSD are also currently under review with multiple health authorities, including in the United States (US) and Japan.
Notes
NMOSD
NMOSD is a rare disease in which the immune system is inappropriately activated to target healthy tissues and cells in the CNS.3,4 Approximately three-quarters of people with NMOSD are anti-AQP4 Ab+, meaning they produce antibodies that bind to a specific protein, aquaporin-4 (AQP4).10 This binding can inappropriately activate the complement system, which is part of the immune system and is essential to the body’s defence against infection, to destroy cells in the optic nerve, spinal cord and brain.3,11,12
It most commonly affects women and begins in the mid-30s. Men and children may also develop NMOSD, but it is even more rare.13,14 People with NMOSD may experience vision problems, intense pain, loss of bladder/bowel function, abnormal skin sensations (e.g., tingling, prickling or sensitivity to heat/cold) and impact on coordination and/or movement.5-7,15,16 Most people living with NMOSD experience unpredictable relapses, also known as attacks. Each relapse can result in cumulative disability including vision loss, paralysis and sometimes premature death.6-8 NMOSD is a distinct disease from other CNS diseases, including multiple sclerosis. The journey to diagnosis can be long, with the disease sometimes misdiagnosed.17-19
CHAMPION-NMOSD
CHAMPION-NMOSD is a global Phase III, open-label, multicentre trial evaluating the safety and efficacy of Ultomiris in adults with NMOSD. The trial enrolled 58 patients across North America, Europe, Asia-Pacific and Japan. Participants were required to have a confirmed NMOSD diagnosis with a positive anti-AQP4 antibody test, at least one attack or relapse in the twelve months prior to the screening visit, an Expanded Disability Status Scale Score of 7 or less and body weight of at least 40 kilograms at trial entry. Participants could stay on stable supportive immunosuppressive therapy for the duration of the trial.20
Due to the potential long-term functional impact of NMOSD relapses and available effective treatment options, a direct placebo comparator arm was precluded for ethical reasons. The active treatment was compared to an external placebo arm from the pivotal Soliris PREVENT clinical trial.
Over a median treatment duration of 73 weeks, all enrolled patients received a single weight-based loading dose of Ultomiris on Day 1, followed by regular weight-based maintenance dosing beginning on Day 15, every eight weeks. The primary endpoint was time to first on-trial relapse, as confirmed by an independent adjudication committee. The end of the primary treatment period could have occurred either when all patients completed or discontinued prior to the Week 26 visit and two or more adjudicated relapses were observed, or when all patients completed or discontinued prior to the Week 50 visit if fewer than two adjudicated relapses were observed. In the trial, there were zero adjudicated relapses, so the end of the primary treatment period occurred when the last enrolled participant completed the 50-week visit.
Patients who completed the primary treatment period were eligible to continue into a long-term extension period, which is ongoing.
Ultomiris
Ultomiris (ravulizumab), the first and only long-acting C5 complement inhibitor, provides immediate, complete and sustained complement inhibition. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the complement cascade over-responds, leading the body to attack its own healthy cells. Ultomiris is administered intravenously every eight weeks in adult patients, following a loading dose.
Ultomiris is approved in the US, EU and Japan for the treatment of certain adults with generalised myasthenia gravis.
Ultomiris is also approved in the US, EU and Japan for the treatment of certain adults with paroxysmal nocturnal haemoglobinuria (PNH) and for certain children with PNH in the US and EU.
Additionally, Ultomiris is approved in the US, EU and Japan for certain adults and children with atypical haemolytic uraemic syndrome to inhibit complement-mediated thrombotic microangiopathy.
Further, Ultomiris is approved in the EU for certain adults with neuromyelitis optica spectrum disorder (NMOSD).
As part of a broad development programme, Ultomiris is being assessed for the treatment of additional haematology and neurology indications.
