Biologics in Chronic Rhinosinusitis With Nasal Polyposis
(CRSwNP)
What this study is about
The prevalence of Chronic Sinusitis with Nasal Polyps (CRSwNP) in the United States is estimated at roughly 4%, which equates to over 13 million Americans. Until recently, the only medical treatment options available for patients with CRSwNP were corticosteroids, with surgery reserved for medical failure.
View original scientific description
The prevalence of Chronic Sinusitis with Nasal Polyps (CRSwNP) in the United States is estimated at roughly 4%, which equates to over 13 million Americans. Until recently, the only medical treatment options available for patients with CRSwNP were corticosteroids, with surgery reserved for medical failure. The development of biologic medications over the last 5 years has revolutionized the treatment of CRSwNP. Three biologic medications have been FDA approved and available for the treatment of CRSwNP: dupilumab, omalizumab, and mepolizumab. However, data from the clinical trials for these drugs do not show universal improvement across all patients with CRSwNP. In fact, there is a wide range of outcomes for patients in these trials. The result is that clinicians have no way of knowing which specific biologic would be the best option for any given patient, nor do they know whether biomarkers can be used to predict response to biologics. It is hoped that findings from this study will inform whether any one biologic has superior outcomes to another and whether clinicians can identify patients at baseline who are most likely to improve on biologic therapy.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age \> 18 years
- Confirmed diagnosis of chronic rhinosinusitis with nasal polyposis using ICAR-21 (International Consensus Statement 20215) criteria
- Bilateral nasal polyposis visible on sinonasal endoscopy
- Nasal polyp score \> 5
- Baseline SNOT-22 total score \> 30
- Patient elects biologic therapy for the management of CRSwNP
- Capable of receiving all 3 biologic therapy medications.
- Treatment with intranasal mometasone ≥200 μg. once daily (or equivalent of another intranasal corticosteroid) for 1-month prior to baseline visit.
Exclusion criteria
- Inability or unwillingness of a participant to give written informed consent or comply with study protocol
- Endoscopic sinus surgery within 6-months preceding enrollment / randomization.
- Oral corticosteroid use within 30-days preceding enrollment / randomization.
- Serum IgE level outside the dosing range for omalizumab (i.e., \<30 IU/ml. or a weight-based dose with insufficient data to determine dose as per FDA dosing chart)
- Comorbid atopic dermatitis, urticaria, or any other condition that would require a specific biologic per the standard of care.
- Currently pregnant or plan to become pregnant within the 6 months after enrollment / randomization.
- Any previous treatment with any of the 3 biologic medications.
- Comorbid cystic fibrosis, CVID, or ciliary dyskinesia.
- Comorbid systemic inflammatory disorders (e.g., GPA, EGPA, Sarcoidosis, SLE)
- Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks for participation in the study, may interfere with the participant's ability to comply with study requirements, or that may impact the quality or interpretation of the data obtained from the study.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
