- Abstract
Background: Dupilumab, an anti-IL4 receptor-α monoclonal antibody, was the first biologic to be approved in Canada for the treatment of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). In phase III clinical trials, it has demonstrated to be effective in reducing nasal polyp size and the severity of symptoms, improve disease-specific quality of life, and to have an acceptable safety profile. This study aims to present long-term follow-up data on disease-specific sinonasal outcomes of patients with CRSwNP who have been treated with dupilumab for up to 3 years in a real-world setting., Methods: Retrospective review of electronic medical records of a single Canadian rhinology center evaluating disease-specific sinonasal outcomes that are routinely collected for clinical care. This study included all patients who received dupilumab for the treatment of CRSwNP and who had completed at least one follow-up visit. The Sino-Nasal Outcome Test (SNOT)-22 was used to evaluate treatment symptom improvement., Results: Ninety-nine patients started dupilumab therapy during the study period. The mean SNOT-22 at the start of therapy was 61.1 (±22.91) At the time of the review, 65 patients had completed 1 year of therapy, 40 had completed 2 years of therapy, and 18 had completed 3 years of therapy. The mean SNOT-22 score at these timepoints was 16.75 (±13.86), 15.02 (±14.40), and 10.22 (±11.56), respectively., Conclusion: This real-world study shows that in patients with CRSwNP treated with dupilumab, improvement in disease-specific quality of life seen after 1 year continues and can be maintained at 3 years of treatment., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: S.J.K.: Site investigator for the LIBERTY NP SINUS-52 study.
