Key Factors Driving the Growth of the Chronic Rhinosinusitis with Nasal Polyps Market 

• Rising CRSwNP Disease Burden: CRSwNP is expected to see a rising disease burden over the forecast period (2026–2036), driven primarily by increasing prevalence, improved diagnosis, and evolving treatment approaches.
• Impact of Nucala and Xolair Approvals on CRSwNP Treatment: The coveted approvals of NUCALA and XOLAIR in the overall existing treatment have added effectiveness in treating CRSwNP.
• Launch of Emerging CRSwNP Therapies: The dynamics of the CRSwNP market are expected to change in the coming years due to the launch of emerging therapies such as Depemokimab (GlaxoSmithKline), Verekitug (UPB-101) (Upstream Bio), Lunsekimig (Sanofi), LY3650150 (Eli Lilly), and others.

Ramandeep Singh, Senior Consultant, Forecasting and Analytics at DelveInsight, said that the treatment strategies are shifting beyond conventional intranasal corticosteroids, systemic steroids, and surgery toward targeted biologic therapies, enabling more personalized and sustained disease control for patients.

Chronic Rhinosinusitis with Nasal Polyps Market Analysis

• The current treatment of CRSwNP includes corticosteroids (intranasal and systemic) in addition to anti-histamines, antibiotics, and NSAIDs, which are given depending on the patient's need.
• When drug treatment doesn't shrink or eliminate nasal polyps, endoscopic surgery is recommended to remove polyps and correct sinus problems that lead to inflammation and polyp development.
• After surgery, a corticosteroid nasal spray is recommended to prevent recurrence of nasal polyps along with biologics.
• Over the years, the US FDA has approved multiple corticosteroids and biologics for CRSwNP, including XHANCE (fluticasone propionate), SINUVA (mometasone furoate) sinus implant, PROPEL (mometasone furoate), DUPIXENT (dupilumab), XOLAIR (omalizumab), and NUCALA (mepolizumab).
• In February 2026, GSK reported that the European Commission approved EXDENSUR (depemokimab) as an add-on therapy with intranasal corticosteroids for adults with severe CRSwNP not adequately controlled with systemic corticosteroids and/or surgery.
• The approval of EXDENSUR was supported by Phase III SWIFT and ANCHOR trial data showing statistically significant and clinically meaningful improvements compared with standard of care alone.
• With this decision, EXDENSUR became the first and only ultra-long-acting biologic approved in the European Union for respiratory diseases, including severe CRSwNP.
• Several companies are actively working in the CRSwNP market. The launch of emerging drugs such as Depemokimab (GlaxoSmithKline), Verekitug (UPB-101) (Upstream Bio), Lunsekimig (Sanofi), LY3650150 (Eli Lilly), and others will change the market dynamics.

Chronic Rhinosinusitis with Nasal Polyps Competitive Landscape

CRSwNP pipeline possesses some drugs in late stage developments to be approved in the near future. Expected launch of emerging therapies, such as Depemokimab (GlaxoSmithKline), Verekitug (UPB-101) (Upstream Bio), Lunsekimig (Sanofi), LY3650150 (Eli Lilly), and others, are expected to further create a positive impact on the market.

Upstream Bio's Verekitug is an engineered, fully human IgG1 monoclonal antibody that targets the TSLP receptor, blocking TSLP-driven pro-inflammatory signaling. In preclinical testing, it showed strong receptor occupancy and robust inhibition of TSLP pathways. Verekitug also reduced cytokine release from CD4+ T cells and ILC2s and completely prevented allergic skin responses in a non-human primate model, indicating potential effectiveness across multiple inflammatory conditions.

GSK is developing depemokimab as a treatment for CRSwNP. This humanized monoclonal antibody against interleukin-5 (IL-5) is designed to bind IL-5 with high affinity and provide long-lasting suppression of IL-5–dependent activity, supporting extended control of eosinophil-driven inflammation.

The anticipated launch of these emerging therapies are poised to transform the CRSwNP market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the CRSwNP market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.

Recent Developments in the Chronic Rhinosinusitis with Nasal Polyps Market

• In February 2026, GSK announced that the European Commission had authorized EXDENSUR (depemokimab) as an add-on treatment alongside intranasal corticosteroids for adults with severe CRSwNP who remain insufficiently controlled despite systemic corticosteroids and/or surgery.
• In January 2026, GSK reported that Japan's Ministry of Health, Labour and Welfare approved EXDENSUR (depemokimab) for the treatment of CRSwNP in patients inadequately controlled with standard therapy.
• In December 2025, the US FDA approved depemokimab for severe asthma but did not approve the CRSwNP indication, without providing detailed reasons. GSK has expressed continued confidence in the therapy's potential for CRSwNP and is maintaining discussions with the FDA.
• In October 2025, TEZSPIRE was approved in the US for the add-on maintenance treatment of adult and paediatric patients aged 12 years and older with inadequately controlled CRSwNP, making it the first and only biologic that targets thymic stromal lymphopoietin (TSLP) to be approved for CRSwNP.
• In September 2025, Upstream Bio reported positive top-line results from the Phase II VIBRANT trial evaluating verekitug for the treatment of CRSwNP. In the 24-week study, verekitug administered at 100 mg every 12 weeks met its primary endpoint, demonstrating a statistically significant and clinically meaningful placebo-adjusted reduction in endoscopic nasal polyp score (NPS) of –1.8.

What is Chronic Rhinosinusitis with Nasal Polyps?

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a long-lasting inflammatory condition of the nose and sinuses in which soft, painless, noncancerous growths, called nasal polyps, develop inside the nasal passages or sinus cavities. These polyps form when the lining of the nose becomes persistently swollen and irritated, often due to immune system dysfunction. People with CRSwNP commonly experience symptoms such as nasal blockage, reduced or lost sense of smell, facial pressure, congestion, and recurring sinus infections. Because the inflammation is ongoing and the polyps tend to recur even after treatment, CRSwNP is considered a chronic condition that often requires long-term medical management.

Chronic Rhinosinusitis with Nasal Polyps Epidemiology Segmentation

The CRSwNP epidemiology section provides insights into the historical and current CRSwNP patient pool and forecasted trends for the leading markets. The US had the highest diagnosed prevalent cases of CRSwNP in the 7MM, with around 2 million cases in 2025. The gender distribution of the disease suggests a male predominance in the US, with 55% of the diagnosed prevalent cases of CRSwNP being males.
