- Brief Summary
Chronic rhinosinusitis with nasal polyps (CRSwNP) or nasal polyposis is a frequent disease leading to a decreased quality of life. The validated course of treatment is firstly a medical one with saline irrigations and topical corticosteroids, followed by surgery (ethmoidectomy) if the medical treatment fails.
In many cases, CRSwNP becomes a recurrent disease despite maximal treatment as previously indicated and it becomes refractory, with a chronically reduced quality of life.
New treatments known as Biologics or Biotherapies in France such as Dupilumab are now available in situations of severe recurrent CRSwNP despite the appropriate treatment.
The goal of this study is to assess the clinical effectiveness of Dupilumab and patient satisfaction, in a cohort of french patients, focusing on the change in quality of life that is expected from said treatment, over a period of one year.
Patients will undergo 6 months of treatment with Dupilumab, the treatment will then be stopped for the next 6 months.
The primary judgment criteria will be the SNOT 22 score, measured before treatment, after 6 months of treatment, and 6 months after stopping treatment, over a telephonic conversation.
- Detailed Description
CRSwNP has existed for over 5000 years, it is a frequent disease, affecting 1 to 4 % of the general population, especially older men and is defined by inflammatory modification of the sinuses and nasal cavities with benign growths of the mucosa known as polyps. It leads to numerous symptoms (nasal blockage, anosmia, nasal dripping, fatigue, pain), which have important consequences in terms of quality of life, social interactions, and by the heavy costs that are brought by medical and surgical treatment.
It is a multifactorial disease for which physiopathology is not well established.
No definitive treatment exists. The appropriate course of treatment aims to control the disease, but not cure it, via topical corticosteroids application which can be facilitated by endoscopic surgery (polypectomy, ethmoidectomy).
Recurrence is frequent after surgery (40 %, 18 months after surgery), which leads to more surgeries that get more complicated and riskier each time.
CRSwNP is also an expensive disease (several thousands of euros per year for one patient), especially in cases of recurrence after surgical treatment. The indirect costs are also high with work absenteeism and decreased productivity making CRSwNP one of the 10 most costly diseases for US employers.
Dupilumab, a biologic treatment targeting the receptors of IL4 and IL13 which are major actors of the inflammatory reaction at hand in CRSwNP, has recently appeared on the market for treatment of severe recurrent CRSwNP despite the appropriate medical and surgical treatment, and has proved its efficacy in randomized clinical trials.
It is a very expensive treatment (1400 euros a month for one patient in France), which is why its clinical effectiveness in a real-life setting must be assessed.
Hypothesis : Dupilumab improves symptoms and quality of life in severe recurrent CRSwNP despite the appropriate medical and surgical treatment.
Objectives : To assess the effect of Dupilumab and patient satisfaction during treatment and after its discontinuation, on symptoms and quality of life in patients suffering from severe and recurrent CRSwNP despite having benefited from the appropriate medical and surgical treatment, in a French real-life cohort.

Group Intervention Description Patients suffering from severe recurrent CRSwNP and treated with Dupilumab Questionnaires Patients suffering from severe recurrent CRSwNP despite having benefited from the appropriate medical and surgical treatment and treated with Dupilumab for 6 months
- Primary Outcome Measures
Name Time Method Assessment of the global effect of Dupilumab 6 months after stopping the treatment by the mean of the SNOT 22 score 6 months after stopping Dupilumab treatment The SNOT22 score is a validated questionnaire for the assessment of symptoms of Chronic rhinosinusitis, ranging from 0 to 110. The more severe are the disease and its associated symptoms, the higher is the score
Assessment of the global effect of Dupilumab 1 day before Dupilumab by the mean of the SNOT 22 score 1 day before Dupilumab The SNOT22 score is a validated questionnaire for the assessment of symptoms of Chronic rhinosinusitis, ranging from 0 to 110. The more severe are the disease and its associated symptoms, the higher is the score
Assessment of the global effect of Dupilumab 6 months of Dupilumab treatment by the mean of the SNOT 22 score 6 months of Dupilumab treatment The SNOT22 score is a validated questionnaire for the assessment of symptoms of Chronic rhinosinusitis, ranging from 0 to 110.
