A Controlled Clinical Study of Dupilumab in Patients With Bilateral Nasal Polyps

United States, Bulgaria, Czechia276 participantsStarted 2016-12-05

Plain-language summary

Primary Objective: To evaluate the efficacy of dupilumab 300 milligram (mg) every 2 weeks (q2w) compared to placebo on a background of mometasone furoate nasal spray (MFNS) in reducing nasal congestion/obstruction (NC) severity and endoscopic nasal polyp score (NPS) in participants with bilateral nasal polyposis (NP). In addition for Japan participants, reduction in computed tomography (CT) scan opacification of the sinuses was a coprimary objective. Secondary Objectives: * To evaluate the efficacy of dupilumab in improving total symptoms score (TSS). * To evaluate the efficacy of dupilumab in improving sense of smell. * To evaluate the efficacy of dupilumab in reducing CT scan opacification of the sinuses (primary objective for Japan). * To evaluate ability of dupilumab in reducing proportion of participants requiring treatment with systemic corticosteroids or NP surgery. * To evaluate the effect of dupilumab on participant reported outcomes and health related quality of life outcome by sinonasal outcome test-22 (SNOT-22). * To evaluate the effect of dupilumab in the subgroups of participants with prior surgery and co-morbid asthma (including non-steroid antiinflammatory drug \[NSAID\] exacerbated respiratory disease \[ERD\]). * To evaluate residual effect in follow up. * To evaluate the safety of dupilumab in participants with bilateral NP. * To evaluate functional dupilumab concentrations (systemic exposure) and incidence of treatment-emergent anti-drug antibodies.

Inclusion criteria: * Participants with bilateral sinonasal polyposis that despite prior treatment with systemic corticosteroids (SCS) anytime within the past 2 years; and/or had a medical contraindication / intolerance to SCS; and/or had prior surgery for NP at the screening visit, had: * An endoscopic bilateral NPS of at least 5 out of a maximum score of 8 (with a minimum score of 2 in each nasal cavity). * Ongoing symptoms (for at least 8 weeks prior to Visit \[V\] 1) of nasal congestion/blockage/obstruction with moderate or severe symptom severity (score 2 or 3) at V1 and a weekly average severity of greater than 1 at the time of randomization (V2), and another symptom such as loss of smell, rhinorrhea (anterior/posterior). * Signed written informed consent. Exclusion criteria: * Participants \<18 years of age. * Participants who were previously treated in dupilumab studies. * Participants who had taken: * Biologic therapy/systemic immunosuppressant to treat inflammatory disease or autoimmune disease (eg, rheumatoid arthritis, inflammatory bowel disease, primary biliary cirrhosis, systemic lupus erythematosus, multiple sclerosis, etc.) within 2 months before V1 or 5 half-lives, whichever was longer. * Any experimental monoclonal antibody (mAB) within 5 half-lives or within 6 months before V1 if the half-life was unknown. * Anti-immunoglobulin E (IgE) therapy (omalizumab) within 130 days prior to V1. * Participants who received leukotriene antagonists/modifiers at V1 un…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
