Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

  1. Brand-side disclosures in response to biosimilar applications
  2. These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

  3. DrugPatentWatch analysis and company disclosures
  4. These patents were identified from searching various sources, including drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

  5. Patents from broad patent text search
  6. For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Dynamics and Financial Trajectory for ULTOMIRIS

Last updated: November 20, 2025

Introduction

ULTOMIRIS (ravulizumab-cwvz) represents a significant advancement in the biological therapeutics landscape, primarily approved for rare and severe complement-mediated disorders. As a C5 complement inhibitor, ULTOMIRIS offers enhanced convenience over its predecessor, Soliris, by providing extended dosing intervals, thus improving patient compliance and expanding its market potential. This analysis examines the evolving market dynamics surrounding ULTOMIRIS, alongside its financial trajectory, driven by clinical demand, competitive positioning, regulatory developments, and healthcare economics.

Market Overview and Therapeutic Landscape

Target Indications and Market Segments

ULTOMIRIS is predominantly indicated for paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS), both rare complement-mediated diseases with high unmet medical needs. The global prevalence of PNH is estimated at approximately 1-2 cases per million, translating into a niche yet high-value market[1]. Similarly, aHUS’s prevalence is estimated at 1-2 cases per million, although diagnosis rates vary regionally[2].

Despite its rarity, the seriousness of these conditions and the lack of curative therapies elevate ULTOMIRIS’s market importance. The drugs' life-long administration necessity, coupled with the high morbidity and mortality associated with these diseases, motivates continuous demand for effective, convenient treatment options.

Competitive Landscape

ULTOMIRIS's primary competitor remains Soliris (eculizumab), also developed by Alexion Pharmaceuticals (a subsidiary of AstraZeneca). Soliris was the first approved complement inhibitor and has established a significant commercial footprint. However, ULTOMIRIS's extended dosing intervals—initiation every 3 weeks versus Soliris’s biweekly schedule—offer a notable differentiation, potentially translating into improved patient adherence and reduced healthcare resource utilization.

Other emerging therapies include ALXN1720 and ravulizumab biosimilars under development, although currently, ULTOMIRIS and Soliris dominate this segment[3].

Market Entry and Adoption Dynamics

Since its approval in 2018, ULTOMIRIS has experienced rapid uptake in North America and Europe, driven by the convenience factor. Commercial adoption hinges on clinician familiarity, reimbursement policies, and patient preferences. The drug’s benefits in reducing infusion burden and improving quality of life serve as strong market drivers.

Regional disparities exist, with higher penetration in developed markets due to healthcare infrastructure, awareness, and regulatory support. Emerging markets show slower adoption attributed to cost barriers and limited healthcare access, despite the significant clinical need.
