ULTOMIRIS Market Summary
Key Factors Driving ULTOMIRIS Growth
1. Long-Acting C5 Inhibition With Significant Convenience Advantage
Ultomiris is a long-acting complement C5 inhibitor engineered from eculizumab to provide sustained complement blockade with fewer infusions.
Key differentiation:
• Intravenous dosing once every 8 weeks, compared with every 2 weeks for earlier therapies.
• This extended dosing interval significantly reduces treatment burden and improves patient compliance.
The improved dosing schedule has encouraged physicians and patients to switch from older complement inhibitors, accelerating market penetration.
2. Rapid Conversion From Earlier Complement Therapy
A major growth driver for Ultomiris has been the conversion of patients from older therapies, particularly eculizumab.
Key adoption trends:
• Over 70% of PNH patients in major markets have transitioned to Ultomiris from its predecessor therapy.
• More than 60% of newly diagnosed PNH patients in Europe initiate therapy with Ultomiris.
This switching strategy allows AstraZeneca to maintain dominance in the complement inhibitor market while improving patient outcomes.
3. Expanding Regulatory Approvals Across Multiple Rare Diseases
Ultomiris has expanded beyond hematology into neurology and nephrology indications.
Major approved indications include:
• Paroxysmal Nocturnal Hemoglobinuria (PNH)
• Atypical Hemolytic Uremic Syndrome (aHUS)
• Generalized Myasthenia Gravis (gMG)
• Neuromyelitis Optica Spectrum Disorder (NMOSD)
In 2024, the U.S. FDA approved Ultomiris for NMOSD, making it the first long-acting C5 inhibitor for this condition.
The approval was based on the CHAMPION-NMOSD trial, which reported zero relapses among treated patients during a median 73-week follow-up.
This expanding label significantly increases the addressable patient population.
4. Growing Complement-Mediated Disease Market
Complement pathway disorders are increasingly recognized as key drivers of rare autoimmune diseases.
Key market trends:
• Rising diagnosis rates for PNH, aHUS, and neurological complement disorders.
• Improved clinical guidelines enabling earlier identification of eligible patients.
These trends are expanding the treatable population and sustaining demand for complement inhibitors like Ultomiris.
5. Strong Commercial Performance and Rapid Revenue Growth
Ultomiris has demonstrated robust commercial growth since launch.
Sales performance highlights:
• $1.03 billion in U.S. sales during the first half of 2024, representing 27% year-over-year growth.
• Ultomiris accounted for 21% of growth in the U.S. hematological disorders market in 2023.

ULTOMIRIS Drug Summary
ULTOMIRIS (Ravulizumab) is a long-acting humanized monoclonal antibody complement C5 inhibitor developed by Alexion (AstraZeneca), administered via intravenous infusion, indicated for treating paroxysmal nocturnal hemoglobinuria (PNH) in adults and pediatric patients one month of age and older to reduce hemolysis; atypical hemolytic uremic syndrome (aHUS) in patients one month and older to inhibit complement-mediated thrombotic microangiopathy (not for Shiga toxin E. coli-related HUS); generalized myasthenia gravis (gMG) in adults; and anti-aquaporin-4 (AQP4) antibody-positive neuromyelitis optica spectrum disorder (NMOSD) in adults, by binding with high affinity to C5 to prevent its cleavage into pro-inflammatory C5a and lytic C5b-9 complex, offering sustained inhibition over 8-week dosing intervals compared to biweekly eculizumab. Engineered for extended half-life via modified Fc region, it rapidly achieves free C5 suppression (<0.5 mcg/mL) post-infusion, stabilizing hemoglobin, reducing transfusions, and improving fatigue in PNH while mitigating kidney damage in aHUS, though it carries a boxed warning for serious meningococcal infections requiring vaccination, REMS enrollment, and prior resolution of active infections.
