- Showed near-elimination of the need for surgery and significant reduction in systemic corticosteroid use compared to placebo.
- Data from the trial presented at the 2025 American Academy of Allergy Asthma & Immunology Joint Congress.
Market Impact
- Patient Population: CRSwNP affects approximately 320 million people globally, indicating a large potential market for Tezspire.
- Treatment Gap: Current therapies (systemic corticosteroids and surgeries) often fail to provide lasting relief, highlighting Tezspire’s role as an innovative treatment option.
Executive Commentary
- Dr. Joseph Han (co-primary investigator): Emphasized the disruption CRSwNP causes to patients’ lives and highlighted Tezspire's ability to significantly improve symptoms and reduce surgical needs.
