Chronic Rhinosinusitis with Nasal Polyps Treatment Market

Nasal Polyposis/Nasal polyps is small, benign drop-like growths appearing in the mucosa (lining tissues) of the nose and may block the nasal passageway. Nasal polyps are a subgroup of chronic rhinosinusitis. Chronic rhinosinusitis is a condition where the nasal cavity and sinuses are inflamed for more than 4 to 12 weeks. Patients suffering from chronic rhinosinusitis condition can be progressed into Chronic Rhinosinusitis with Nasal Polyps, and chronic rhinosinusitis without NP (CRSsNP). Only a portion of chronic rhinosinusitis will develop nasal polyps.

CRSwNP is a potentially debilitating condition in adults that are characterized by inflammation of the nose and paranasal sinuses with the presence of nasal polyps. People with a history of chronic sinus infections, allergic rhinitis, asthma, and cystic fibrosis, sensitivity to NSAIDs like ibuprofen and aspirin, and Churg-Strauss syndrome are more prone to get nasal polyps. Patients suffering from nasal polyps may experience chronic nasal congestion, running nose, postnasal drip, reduced sense of smell and taste, difficulty in breathing, pressure in the face or forehead area, snoring, sleep apnea, and others.

Chronic Rhinosinusitis with Nasal Polyps Diagnosis

For the diagnosis of nasal polyps, an ENT specialist or any other physician first looks into the nasal passages with a special lighted instrument known as a nasoscope. The most preferred techniques are confirming the location, size, and severity of polyps nasal endoscopy, and radiological imaging. Further allergy tests and blood tests can be done to determine other disease-related components.

Chronic Rhinosinusitis with Nasal Polyps Treatment

Corticosteroids are considered the first-line therapy for the treatment of nasal polyps. Initially, nasal corticosteroids are recommended for treatment. If the patient does not progress, they may be shifted to oral corticosteroids and then to injectable corticosteroids. If the corticosteroids do not show progress in the condition, surgical intervention is the next treatment of choice. Biologics can be given to treat severe polyps, treat post-surgery reoccurrence cases, and treat patients who cannot undergo surgery. Anti-allergic NSAIDs can be added to the regimen depending on the condition.

The currently recommended range of pharmacological treatments includes mainly biologics and corticosteroids, including NUCALA (mepolizumab), DUPIXENT (dupilumab), XOLAIR (omalizumab), XHANCE (fluticasone propionate), SINUVA (mometasone furoate) Sinus Implant, and PROPEL (mometasone furoate) as currently approved for treating nasal polyps and CRSwNP. With many treatment options already present, the market anticipates the launch of emerging products with novel CRSwNP MoA targets and the onset of action.

CRSwNP is a complex and frequent respiratory condition that poses significant challenges to both the patients who experience it and the physicians who treat them. Treatment aims to eliminate or significantly reduce the size of the nasal polyps, resulting in relief of nasal obstruction, improvement in sinus drainage, and restoration of olfaction and taste. A handful of clinical trials are expected to change the landscape of the emerging therapeutic market in the forecast period. Profound disease understanding, development of novel therapeutic agents, and patient-centered treatment approaches will improve patient outcomes in the coming years.

Chronic Rhinosinusitis with Nasal Polyps Epidemiology

As the market is derived using a patient-based model, the CRSwNP epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by Prevalent cases of Chronic Rhinosinusitis (CRS), Diagnosed prevalent cases of CRS, Diagnosed prevalent cases of Chronic Rhinosinusitis with Nasal Polyps, and Gender-specific diagnosed prevalent cases of Chronic Rhinosinusitis with Nasal Polyps, in the 7MM covering, the United States, EU4 countries (Germany, France, Italy, and Spain), United Kingdom, and Japan from 2022 to 2036.

• The total prevalent cases of CRS in the 7MM were found to be approximately 71 million cases in 2025, which are expected to increase at a significant CAGR during the study period (2022-2036).
• Based on DelveInsight's estimations, total diagnosed prevalent cases of CRS in the 7MM were found to be nearly 18 million in 2025, which are expected to increase at a significant CAGR during the forecast period of 2026-2036.
• As per DelveInsight's estimates, the 7MM accounted for 4.5 million diagnosed prevalent cases of CRSwNP in 2025, which are expected to increase during the study period. As per DelveInsight's analysis, in the United States 25% of the total diagnosed prevalent cases of CRS develop into CRSwNP.
• As per DelveInsight's epidemiology model for CRSwNP, 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.

Chronic Rhinosinusitis with Nasal Polyps Recent Developments

• 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.

Chronic Rhinosinusitis with Nasal Polyps Marketed Drugs

• NUCALA (mepolizumab): GlaxoSmithKline

GSK's NUCALA (mepolizumab) is the first IL-5 therapy approved as an add-on treatment in the US for adults with CRSwNP to target eosinophilic inflammation in adult patients 18 years of age and older with inadequate response to nasal corticosteroids. The recommended dosage of mepolizumab is 100 mg, administered once every 4 weeks by subcutaneous injection into the upper arm, thigh, or abdomen.

Mepolizumab is an IL-5 antagonist (IgG1 kappa). IL-5 is the major cytokine responsible for the growth and differentiation, recruitment, activation, and survival of eosinophils. Mepolizumab binds to IL-5 with a dissociation constant of 100 pM, inhibiting the bioactivity of IL-5 by blocking its binding to the alpha chain of the IL-5 receptor complex expressed on the eosinophil cell surface. By inhibiting IL-5 signaling, mepolizumab reduces the production and survival of eosinophils; however, the mechanism of mepolizumab action in asthma, CRSwNP, EGPA, and HES has not been definitively established.

The US FDA approved NUCALA in July 2021 based on positive results from the pivotal SYNAPSE study.

Chronic Rhinosinusitis with Nasal Polyps Emerging Drugs

• Verekitug (UPB-101): Upstream Bio

Verekitug is a novel recombinant fully human immunoglobulin G1 (IgG1) monoclonal antibody that binds to the TSLP receptor and inhibits proinflammatory signaling initiated by TSLP. In preclinical studies, verekitug demonstrated high occupancy of the TSLP receptor and potent inhibition of TSLP signaling. Additionally, verekitug inhibited cytokine production from both CD4+ T cells and ILC2 cells and completely suppressed skin allergic reactions in a non-human primate model, suggesting that it may be effective against multiple types of inflammation.

• Depemokimab (GSK3511294): GSK

GSK is developing depemokimab for the treatment of CRSwNP. It is a humanized anti-interleukin-5 (IL-5) monoclonal antibody designed as a novel biologic with high binding affinity and sustained suppression of IL-5-mediated activity, enabling prolonged control of eosinophilic inflammation.
