What is the purpose of this trial?

This trial tests dupilumab, a medication, to determine its effectiveness for people with severe eosinophilic chronic sinusitis without nasal polyps. This condition causes painful and persistent sinus issues that do not improve with standard nasal sprays. Participants should experience symptoms like nasal blockage, nasal discharge, or facial pain and have a specific type of sinusitis involving multiple sinuses. The trial compares dupilumab with a placebo (a non-active treatment) to assess effectiveness. For those with eosinophilic sinusitis affecting daily life who have not found relief with other treatments, this trial may be suitable. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications before joining. For example, you must not have taken biologic therapy or systemic immunosuppressants within 2 months before screening, and you must have been on a continuous treatment with leukotriene antagonists for at least 30 days prior to screening. Please check with the trial team for specific guidance on your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that dupilumab has been tested for safety in various conditions. Some studies found that people taking dupilumab experienced more common colds and mild skin reactions at the injection site compared to those taking a placebo. Another study found that dupilumab was generally safe when used with other treatments for certain diseases. While these studies provide some safety information, clinical trials like this one help determine how safe and effective a treatment is for different conditions. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for severe eosinophilic chronic sinusitis, which often involve steroids and nasal sprays, Dupilumab offers a novel approach by targeting the interleukin-4 receptor alpha. This mechanism disrupts the signaling of certain proteins that drive inflammation, providing a more precise attack on the root causes of the condition. Researchers are excited because this could mean fewer side effects and potentially better long-term outcomes compared to traditional therapies.

What evidence suggests that dupilumab might be an effective treatment for severe eosinophilic chronic sinusitis?

Research has shown that dupilumab effectively treats chronic rhinosinusitis with nasal polyps, similar to eosinophilic chronic sinusitis. Studies have found that patients using dupilumab experienced significant improvements in symptoms and sinus health, such as reduced nasal blockage and better sinus scan results. Dupilumab blocks certain proteins that cause inflammation, reducing sinus swelling and related symptoms. In this trial, participants will receive either dupilumab or a placebo to evaluate its potential use in treating severe eosinophilic chronic sinusitis. ^{5 6 7 8 9}

Published Research Related to This Trial

In a study involving 724 patients with severe chronic rhinosinusitis with nasal polyps, dupilumab significantly improved symptoms of nasal congestion, loss of smell, and rhinorrhoea compared to placebo, with improvements seen as early as Week 2 and continuing through Week 52.

A higher proportion of patients treated with dupilumab reported a reduction from moderate-to-severe symptoms to no-to-mild symptoms at multiple time points, indicating its efficacy in managing this condition regardless of prior surgery or coexisting asthma.

Dupilumab provides early and durable improvement of symptoms in patients with chronic rhinosinusitis with nasal polyps. Gevaert, P., Lee, SE., Settipane, RA., et al.[2023]

In a study of 130 patients treated with dupilumab for severe chronic rhinosinusitis with nasal polyps over 18 months, there was a significant reduction in nasal polyposis and improvement in symptoms and quality of life.

The treatment was associated with a transient increase in blood eosinophils and a gradual decrease in total IgE levels, indicating potential changes in immune response, although IgG and IgA levels remained within normal ranges.

Dupilumab's Impact on Blood Parameters in Nasal Polyposis: 18-Month Follow-Up in Real Life. Loperfido, A., Ciofalo, A., Cavaliere, C., et al.[2023]

Dupilumab is an effective treatment for chronic rhinosinusitis with polyposis (CRSwNP), showing significant improvements in patients' subjective disease burden and objective measures, regardless of specific disease characteristics like aspirin exacerbated respiratory disease (AERD) or elevated eosinophil levels.

In a study of 75 patients, dupilumab therapy was reported to be more effective than functional endoscopic sinus surgery (FESS) in certain cases, indicating that some patients may benefit more from dupilumab than from surgical intervention.

Subgroups in the treatment of nasal polyposis with dupilumab: A retrospective study. Bertlich, M., Freytag, S., Dombrowski, T., et al.[2023]

In a study of 66 patients with chronic rhinosinusitis with nasal polyps (CRSwNP), dupilumab significantly reduced symptoms and nasal polyp scores after 6 and 12 months, indicating its effectiveness as a treatment.

The safety profile of dupilumab was favorable, with only 12.7% of patients experiencing injection site reactions and 11.1% having transient hypereosinophilia, suggesting it is a safe option for managing CRSwNP.

Dupilumab significantly improved symptoms of chronic rhinosinusitis with nasal polyps (CRSwNP) in patients regardless of their surgical history, demonstrating its efficacy across different subgroups based on prior surgeries and time since last surgery.

Patients who had undergone surgery more recently (within <3 years) experienced greater improvements in nasal polyp scores and other measures compared to those who had surgery longer ago, while the safety profile of dupilumab remained consistent with previous findings.

Dupilumab, a monoclonal antibody used to treat conditions like asthma and atopic dermatitis, can cause hypereosinophilia (high eosinophil levels) as a potential adverse effect, which poses a challenge for clinicians.

An algorithm has been proposed to help manage dupilumab-induced hypereosinophilia, allowing for proper investigation of related health issues while minimizing unnecessary discontinuation of the medication.

Dupilumab significantly improved symptoms and objective measures of chronic rhinosinusitis with nasal polyps (CRSwNP) in patients, regardless of whether they also had allergic rhinitis, based on a pooled analysis of 724 patients from two phase III studies.

The treatment also reduced the need for systemic corticosteroids and sinonasal surgery, demonstrating its efficacy and safety profile, which was consistent across patients with and without allergic rhinitis.
