AstraZeneca and Amgen's Tezspire (tezepelumab) received a positive CHMP recommendation for approval in the EU to treat adults with chronic rhinosinusitis with nasal polyps (CRSwNP). The opinion was based on the Phase III WAYPOINT trial, which showed Tezspire reduced nasal polyp size by a mean of 2.08 points and nasal congestion by 1.04 points versus placebo at Week 52, with p<0.001 for both co-primary endpoints.

WAYPOINT data also reported a 98% near-elimination of the need for surgery and an 89% reduction in systemic corticosteroid use versus placebo. Safety and tolerability were consistent with the known profile. Regulatory reviews are ongoing in multiple other countries.

  • Statistically significant and clinically meaningful decreases in Nasal Polyp Score (-2.08) and Nasal Congestion Score (-1.04) versus placebo at Week 52 (p<0.001)
  • Substantial reductions in need for surgery (98%) and systemic corticosteroid use (89%) versus placebo reported in WAYPOINT
  • Safety and tolerability consistent with the known profile of tezepelumab
  • Established commercial and development collaboration with Amgen, and Tezspire already approved for severe asthma in multiple countries
Negative
  • None.

Insights

TL;DR: CHMP positive opinion on WAYPOINT results materially advances Tezspire's EU label into CRSwNP, supported by strong efficacy on polyp size and congestion.

The CHMP recommendation is grounded in robust Phase III co-primary endpoint results showing statistically significant and clinically meaningful improvements in Nasal Polyp Score and Nasal Congestion Score at 52 weeks. The magnitude of reductions and the reported near-elimination of surgery and large corticosteroid-use reduction indicate potential to shift treatment pathways for uncontrolled CRSwNP. Safety was consistent with prior data, which supports regulatory acceptability. Ongoing reviews in other jurisdictions could expand global indications if approved.

TL;DR: A positive CHMP opinion positions Tezspire to capture unmet need in CRSwNP and complements its existing severe asthma franchise.

Tezspire already approved and used in severe asthma worldwide, with over 100,000 treated patients cited, and the EU CRSwNP recommendation leverages that established footprint. The reported reductions in surgery and systemic corticosteroid reliance signal potential to reduce healthcare utilization and improve patient quality of life, which can support payer discussions. The collaboration terms with Amgen for shared costs and profit-split have defined commercial mechanics across regions.

Tezspire Recommended for Approval in EU for CRSwNP
 
 
 
22 September 2025
 
Tezspire recommended for approval in the EU by CHMP for chronic rhinosinusitis with nasal polyps
 
Recommendation based on WAYPOINT Phase III trial results showing Tezspire reduced nasal polyp severity and nasal congestion, nearly eliminated the need for surgery and significantly reduced systemic corticosteroid use vs. placebo
 
AstraZeneca and Amgen's Tezspire (tezepelumab) has been recommended for approval in the European Union (EU) for the treatment of adult patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
 
The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based its positive opinion on results from the WAYPOINT Phase III trial, which were presented at the 2025 American Academy of Allergy Asthma & Immunology (AAAAI)/World Allergy Organization (WAO) Joint Congress and simultaneously published in The New England Journal of Medicine.1,2
 
In the WAYPOINT trial, Tezspire demonstrated a statistically significant and clinically meaningful reduction in nasal polyp severity, as measured by the co-primary endpoints; Nasal Polyp Score (NPS) by -2.08 (95% CI: -2.40, -1.76; p<0.001) and nasal congestion (measured by participant-reported Nasal Congestion Score [NCS]) by -1.04 (95% CI: -1.21, -0.87; p<0.001) at week 52 compared to placebo.1,2 Data also showed Tezspire enabled near-complete elimination of the need for surgery (98%) and significantly reduced the need for systemic corticosteroid treatment (89%) compared to placebo.2
 
Dr. Oliver Pfaar, Chair of the Section Rhinology and Allergy, ENT-Department, University Hospital Marburg, Philipps-Universität Marburg in Marburg, Germany and investigator in the WAYPOINT trial, said: "Chronic rhinosinusitis with nasal polyps is a challenging condition. For many patients, current therapies don't offer lasting relief causing a cycle of repeat surgeries and ongoing treatment with oral corticosteroids, which can result in serious side effects. This positive CHMP recommendation is very encouraging and if approved, tezepelumab will provide patients and clinicians in Europe with an important new treatment option that has demonstrated rapid, sustained symptom relief."
 
Ruud Dobber, Executive Vice President and President, BioPharmaceuticals Business Unit, AstraZeneca, said: "The CHMP recommendation brings us closer to offering Tezspire to patients across the EU who face the daily challenges of this disruptive and difficult-to-treat disease. The unique way Tezspire works means it addresses the multiple drivers of epithelial-driven inflammation associated with chronic rhinosinusitis with nasal polyps. This pivotal milestone builds upon Tezspire's foundational impact in severe asthma and reinforces our commitment to transforming respiratory care."
 
CRSwNP is a chronic inflammatory condition characterised by persistent inflammation and benign polyp growths within the nasal cavity that can obstruct airflow and impair sense of smell, taste and sleep.3-7 This condition affects up to roughly 320 million people worldwide.7 Nearly half of the patients diagnosed with CRSwNP in Europe remain uncontrolled, and for many patients, current therapies such as systemic corticosteroids and repeated sinus surgeries do not offer lasting relief.4,8
 
The safety profile and tolerability of tezepelumab in the WAYPOINT trial were consistent with the known profile of the medicine.2
 
Regulatory applications are currently under review in the US, China, Japan and several other countries based on the WAYPOINT trial. Tezspire is currently approved for the treatment of severe asthma in the US, EU, Japan and more than 60 countries across the globe.9-11
 
Notes
 
Chronic Rhinosinusitis with Nasal Polyps (CRSwNP (nasal polyps))  
CRSwNP is a complex inflammatory disorder, characterised by persistent inflammation of the nasal mucosa accompanied by benign growths, called nasal polyps.3,4 Nasal polyps can block nasal passages and lead to breathing problems, difficulty in sense of smell, nasal discharge, facial pain, sleep disturbance and other adverse effects on quality of life.5,7
  
Epithelial dysfunction and inflammation are important characteristics of chronic rhinosinusitis and impede the ability of the epithelium to act as a physical and immunological barrier against the external environment.12,13 Thymic stromal lymphopoietin (TSLP) is an epithelial cytokine that has been implicated in shared pathophysiological processes underlying severe asthma and CRSwNP.13
  
Current treatments for CRSwNP include intranasal and/or systemic corticosteroids, surgery and biologics.4,7,14-19
 
Phase III WAYPOINT trial 
WAYPOINT is a double-blind, multi-centre, randomised, placebo-controlled, parallel group trial designed to evaluate the efficacy and safety of tezepelumab in adults with severe CRSwNP.1,2,20 Participants received tezepelumab or placebo, administered via subcutaneous injection.1,2,20 The trial also included a post-treatment follow-up period of 12-24 weeks for participants who completed the 52-week treatment period.2,20
 
The co-primary endpoints of the trial, were change from baseline in total nasal polyp size, measured by the endoscopic total Nasal Polyp Score, and change from baseline in bi-weekly mean nasal congestion, measured by the participant reported Nasal Congestion Score evaluated as part of the daily Nasal Polyposis Symptom Diary.2,20 Key secondary endpoints included loss of smell; improvement in disease specific health-related quality of life as measured by SinoNasal Outcome Test (SNOT-22) score; Lund-Mackay score; time to surgery decision and/or systemic corticosteroids for nasal polyposis; time to nasal polyposis surgery decision; time to systemic corticosteroids for nasal polyposis; Nasal Polyposis Symptom Diary total symptom score and, in the population with co-morbid asthma, pre-bronchodilator FEV1 at Week 52.2,20
 
Tezepelumab  
Tezepelumab is being developed by AstraZeneca in collaboration with Amgen as a first-in-class human monoclonal antibody that inhibits the action of thymic stromal lymphopoietin (TSLP), a key epithelial cytokine that sits at the top of multiple inflammatory cascades and is critical in the initiation and persistence of allergic, eosinophilic and other types of epithelial inflammation associated with severe asthma, CRSwNP and other inflammatory diseases.12,13
  
TSLP is released by the epithelium in response to environmental triggers (including allergens, viruses and other airborne particles) associated with asthma, CRSwNP, chronic obstructive pulmonary disease (COPD), eosinophilic esophagitis (EoE) and other diseases.13 Across these disease states, the expression of TSLP is increased and correlates with disease severity.7,12
  
Tezspire is approved as a single-use pre-filled syringe and auto-injector for self-administration in the US and EU. 9-11 Since 2021, over 100,000 patients have been treated with Tezspire for severe asthma. 21
  
Beyond CRSwNP, Tezspire is also being explored in Phase III trials in COPD and EoE.22,23 In October 2021, Tezspire was granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of EoE.  
 
Amgen Collaboration  
The 2012 Collaboration Agreement between Amgen and AstraZeneca has been amended and updated over time. For Tezspire, both companies continue to share costs and profits equally after payment by AstraZeneca of a mid single-digit inventor royalty to Amgen. AstraZeneca continues to lead development and Amgen continues to lead manufacturing. All aspects of the collaboration are under the oversight of joint governing bodies. Under the agreement, Amgen and AstraZeneca will jointly commercialise Tezspire in the US. Amgen will record product sales in the US, with AZ recording its share of US profits as Collaboration Revenue. Outside of the US, AstraZeneca will record product sales, with Amgen recording profit share as Other/Collaboration revenue.
