Safety Profile of Dupilumab Approved for Chronic Rhinosinusitis with Nasal Polyposis: Analysis from the European Spontaneous Adverse Event Reporting System

Introduction: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is characterized by a type 2 pattern of inflammation resulting in the production of some cytokines such as interleukin (IL)-4, IL5, and IL13. Options for treatment-resistant CRSwNP include aspirin desensitization, recurrent topic and...

Description
Summary:Introduction: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is characterized by a type 2 pattern of inflammation resulting in the production of some cytokines such as interleukin (IL)-4, IL5, and IL13. Options for treatment-resistant CRSwNP include aspirin desensitization, recurrent topic and systemic corticosteroid use, and functional endoscopic sinus surgery (FESS). However, frequent relapses after medical and surgical treatment have been observed. Thus, dupilumab, a human recombinant monoclonal IgG4 antibody, changes radically the treatment of CRSwNP because of its binding effects on major drivers of human type 2 inflammatory processes [1-3]. Considering its recent approval, it may be useful to evaluate its safety profile. Objective: The aim of this study was to describe better adverse drug reactions (ADRs) related to dupilumab in the treatment of CRSwNP analyzing all individual case safety reports (ICSRs) collected into the European Spontaneous Reporting System (SRS) database. Methods: All ICSRs recorded starting from the drug approval up to 31 December 2021 with dupilumab reported as suspected and having the specific indication of CRSwNP were considered. A descriptive analysis was conducted to assess demographic characteristics and dupilumab-related variables. Results: Out of 10,400 ICSRs related to dupilumab, only 481 (4.6%) had CRSwNP indication, of which 68.2% were related to adults and 54.3% to females. The 68.4% were serious; however, ICSRs mainly led to a completely or partial recovering (25.4%) and 8 cases were fatal (1.7%). The time to onset (TTO) of ADRs was 25 (1-84.75) days while the time to resolution (TTR) was 5 (1.75-15.75) days. Analyzing ADRs by System Organ Classes (SOCs), the most reported were general and administration site conditions (36.4%) followed by injuries (21.6%), infections (21.2%), respiratory (19.1%), skin (16.6%), and nervous system disorders (16.4%). Looking at Preferred Terms (PTs), arthralgia (7.3%), eosinophilia (6.9%), COVID-19 (6.0%), pyrexia (5.8%), asthenia (5.6%), rash (5.4%), and dyspnoea (5.2%) were the most reported. The 7.5% of ICSRs described an aggravated condition with persistent nasal polyps: in 4 cases (0.8%) a nasal polypectomy was required. Considering fatal ICSRs, two cases were related to progression of COVID-19, one to road traffic accident, one to accidental death and the others were not fully specified. Conclusion: These results showed that dupilumab-related ICSRs are not commonly reporte
