Dupilumab Severe Eosinophilic Chronic Sinusitis Without Nasal Polyposis

January 21, 2025 updated by: University of South Florida

An Evaluation of Dupilumab in Patients With Severe Eosinophilic Chronic Sinusitis Without Nasal Polyposis

The investigators will investigate the efficacy of dupilumab in patients with severe eosinophilic CRSsNP who are resistant to the conventional treatment with intranasal corticosteroids and have significantly extensive disease involving more than 2 sinuses bilaterally in sinus CT scan and Lund-Mackay sinus (LMK) CT score >=10 at baseline.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators will use high blood eosinophils (>=200) as a biomarker for eosinophilic CRSsNP and investigate the efficacy of dupilumab in patients with severe eosinophilic CRSsNP who are resistant to the conventional treatment with intranasal corticosteroids and have significantly extensive disease involving more than 2 sinuses bilaterally in sinus CT scan and Lund-Mackay sinus (LMK) CT score >=10 at baseline. In addition, the investigators will have a prespecified enrollment goal of at least 50% of patients with type 2 inflammatory diseases such as asthma, allergic rhinitis, and/or atopic dermatitis on the basis of patient-reported history and will stratify subject numbers between dupilumab treatment and placebo group.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Lund-Mackay sinus computed tomography (LMK-CT) score
Time Frame: 24 weeks
Change in LMK-CT score in dupilumab group compared to control group. The total score ranges from 0 (normal) - 24 (more opacified): higher score indicates worse status.
24 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in participant-reported symptoms scores of sinusitis
Time Frame: 24 weeks
Change in baseline in participant-reported symptoms scores of sinusitis in dupilumab group compared to control group. Morning symptoms of sinusitis will be assessed using a 0 (no symptoms) - 3 (severe symptoms) categorical scale, where a higher score indicates severe symptoms.
24 weeks
Change in visual analogue scale score for sinusitis
Time Frame: 24 weeks
Change in visual analogue scale score for sinusitis in dupilumab group compared to control group. the severity of sinusitis symptoms will be assessed on a 0 cm (not troublesome) - 10 cm (worst thinkable troublesome) where a higher score indicates worst thinkable troublesome.
24 weeks
Change in nasal peak inspiratory flow
Time Frame: 24 weeks
Change in nasal peak inspiratory flow in dupilumab group compared to placebo group.
24 weeks
Change in University of Pennsylvania smell identification test (UPSIT) scores
Time Frame: 24 weeks
Change in UPSIT scores in dupilumab group compared to placebo group. Total score ranges from 0 (anosmia)-40 (normal sense of smell), a lower score indicates severe smell loss.
24 weeks
Time to first response in LMK-CT score
Time Frame: 24 weeks
50 percent improvement in LMK-CT score in dupilumab group compared to placebo group
24 weeks
Change in sinonasal outcome test (SNOT-22) score
Time Frame: 24 weeks
Change in 22-item SNOT-22 test score in dupilumab group compared to placebo group. The total score may range from 0 (no problem)-110 (worst quality of life), higher scores represent the worst quality of life; minimal clinically important change ≥ 8.90.
24 weeks
Change in biomarkers concentrations in nasal secretion measured by enzyme-linked immunosorbent assay (ELISA)
Time Frame: 24 weeks
Change in biomarkers concentrations in nasal secretion in dupilumab group compared to placebo group. ELISA will be done to measure biomarkers concentrations (pg/mL): ECP, IL-4, IL-5, IL-13, periostin, eotaxin-3, TARC, and IgE
