About this study

Official title: Dupilumab Treatment Effects in an Ethnically Diverse Population With Chronic Rhinosinusitis With Nasal Polyposis (CRSwNP) Effect of 16-week Dupilumab Treatment on Sinonasal Respiratory Symptoms and Sense of Smell in Ethnically Diverse Patients With Chronic Rhinosinusitis and Nasal Polyposis (CRSwNP)

The central hypothesis of this study is that the addition of dupilumab treatment onto standard-of-care intranasal corticosteroids will improve patient-reported measures of disease activity and sense of smell in a cohort of mostly ethnical and racial minority patients with CRSwNP.

Read the detailed description

First, it will confirm the effectiveness of dupilumab in the treatment of CRSwNP in ethnic and racial minority patients who have traditionally been underrepresented in existing clinical trials of biologics in CRSwNP Second, this research will establish a biomarker of therapeutic response to dupilumab identifying the biological effect of dupilumab in CRSwNP patients and its association with symptom improvement.

Finally, the investigators will measure the effect of dupilumab on asthma symptoms and lung function in patients with CRSwNP and comorbid asthma.

There will be a screening visit, followed by a baseline visit where the medication will be given. Follow-up visits will be scheduled at 2 weeks and then 16 weeks from baseline. Long-term visits will take place in 36 and 52 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline in Sino-Nasal outcome test (SNOT-22) score

    Change in sinonasal values from baseline will be assessed using the 22-item Sino-Nasal Outcome Test (SNOT-22). The SNOT-22 is a 22-item patient questionnaire used to measure symptom severity and related quality of life in people with chronic rhinosinusitis or nasal problems. Each of the 22 items is measured using a 6-point Likert scale ranging from 0 ("No problem") to 5 ("Worst possible problem"), yielding an overall scoring range of 0-110, such that higher scores are indicative of worsening symptom burden. This outcome measure will only be assessed longitudinally in the participants receiving Dupilumab.

    Measured: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration

  2. Change from baseline in Smell Function

    Change in smell function from baseline will be assessed using the University of Pennsylvania Smell Identification Test (UPSIT). The UPSIT is a standardized 40-item "scratch-and-sniff" test of olfactory function. Each participant is provided with four small booklets containing a total of 40 microencapsulated scent strips and is instructed to scratch the strip, sniff the odor, and pick the correct answer from a multiple-choice list of four options per item. Each correct identification of a scratch-and-sniff odor gives one point, yielding an overall possible scoring range of 1-40. Lower scores reflect a reduced ability to identify odors. This outcome measure will only be assessed longitudinally in the participants receiving Dupilumab.

    Measured: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration

  3. Change from baseline in Nasal Peak Flow (NPF)

    Change in NPF values from baseline will be evaluated in the clinic. Peak nasal inspiratory flow (PNIF) normal values typically range from 80-180 Liters per minute (L/min) in healthy adults, varying based on age, sex, and physical stature. Higher values are indicative of greater nasal airway patency. Change from baseline values will be expressed in units of L/min. This outcome measure will only be assessed longitudinally in the participants receiving Dupilumab.

    Measured: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration

Secondary outcomes (3)

  1. Change from baseline in urinary Leukotriene E4 (uLTE₄) levels

    Change in uLTE₄ levels from baseline will be assessed in the clinic. Urine samples will be collected during each specified timepoint, and samples will be processed and analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) or the appropriate immunoassay. Normal reference ranges for uLTE4 is ≤ 104 picograms per milligram (pg/mg) creatinine. Elevated uLTE₄ levels are indicative of heightened systemic or airway cysteinyl leukotriene activity and serve as a reliable, non-invasive biomarker for several inflammatory, respiratory, and hypersensitivity disorders. Change from baseline values will be expressed in units of pg/mg. This outcome measure will only be assessed longitudinally in the participants receiving Dupilumab.

    Measured: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration

  2. Change from Baseline in Absolute Peripheral Blood Eosinophil Count

    Changes in Absolute Eosinophil Count from peripheral blood from baseline will be assessed in the clinic. Blood samples will be drawn during each prespecified timepoint and analyzed using automated hematology analyzers or manual microscopy as part of a Complete Blood Count (CBC) with differential. Absolute Eosinophil Counts (AEC) vary by laboratory but are generally in the range of 0-500 cells per microliter (cells/µL) of blood. Elevated AEC in peripheral blood is indicative of increased in eosinophilic conditions as evident from rashes, worsening pulmonary symptoms and/or neuropathy. Change from baseline values will be expressed in cells/uL. This outcome measure will only be assessed longitudinally in the participants receiving Dupilumab.

    Measured: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration

  3. Change from Baseline in Serum Total Immunoglobulin E (IgE) Levels

    Changes in total serum IgE levels from baseline will be assessed in the clinic. Blood samples will be drawn during each prespecified timepoint and analyzed using automated immunoassay techniques to measure the concentration of circulating IgE. Standard reference ranges vary by laboratory assay, age, and individual baseline factors but are generally in the range of 0-100 International Units per milliliter (IU/mL) of blood. Elevated IGe concentrations can be indicative of a number of clinical indications including atopic and allergic diseases. Change from baseline values will be expressed in IU/mL. This outcome measure will only be assessed longitudinally in the participants receiving Dupilumab.

    Measured: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration

An observational study of Chronic Rhinosinusitis With Nasal Polyps, run by Montefiore Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 14 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in Sino-Nasal outcome test (SNOT-22) score (time frame: Baseline, 2 weeks, 16 weeks, 36 weeks, and 52 weeks post-administration). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05246267, which also lists 41 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2026; AzTrials last refreshed its copy on 7 Nov 2026.
