This is a single-arm extension study to investigate the long-term safety, tolerability, and efficacy of lunsekimig in adult participants with inadequately controlled CRSwNP who have completed a previous lunsekimig CRSwNP clinical study (also referred to as the parent study ACT18207). The study duration will be up to approximately 56 weeks per participant, 52 weeks of treatment period, and 4 weeks of follow-up.
EFC18419 is a multinational, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 study with 3 treatment groups. The purpose of the study is to evaluate the efficacy, safety and tolerability of 2 dosing regimens of itepekimab compared to placebo as add-on therapy to intranasal corticosteroids (INCS) in male and female participants with chronic rhinosinusitis with nasal polyps (CRSwNP) aged 18 years of age and older. Study details include: * The study duration per participant (4-week screening, 52-week treatment, 20-week safety follow-up) will be up to 76 weeks. For participants transitioning to the LTS18420 study, the study duration will be 56 weeks. * The treatment duration will be up to 52 weeks. * The number of visits will be 9 site visits and 20 phone/home visits.

The main objective of this study is to evaluate treatment outcomes of tezepelumab among participants with physician-determined surgery-eligible CRSwNP, with or without asthma. Study details include: 1. The study duration will be up to 40 weeks. 2. The treatment duration will be up to 24 weeks. 3. The visit frequency will be once every 4 weeks (Q4W).
The main purpose of this study is to evaluate the efficacy and safety of lebrikizumab in adult participants with chronic rhinosinusitis and nasal polyps treated with intranasal corticosteroids. The study will last about 18 months.
Three-dimensional (3D) printing has been an emerging technology with uses in a wide array of fields. This research aims to use 3D printing as a tool to provide personalized education to maximize treatment efficacy based on the patient's individual anatomy. With increased irrigation to the sinuses, we hypothesize there will be improved patient satisfaction and higher quality of life. The outcomes of this research could lead to a new option for patients who live with chronic rhinosinusitis are not candidates for surgery or are interested in less invasive options. The 3D printed nasal replica is not something that would be implanted, rather it is a hand-held device used specifically for participants to better understand their nasal anatomy.
The goal of this laboratory study is the examine the effect of mepolizumab drug on the health and function of the cells lining the human nasal airways in vitro cell culture derived from patients with chronic rhinosinusitis with nasal polyposis. The main questions the study aims to study are: 1. To see what mepolizumab does to suppress inflammation of the human cells. 2. To see what mepolizumab does to maintain barrier integrity of epithelial cells
The central hypothesis of this study is that the addition of dupilumab treatment onto standard-of-care intranasal corticosteroids will improve patient-reported measures of disease activity and sense of smell in a cohort of mostly ethnical and racial minority patients with CRSwNP
The goal of this observational study is to learn what can predict the return of the sense of smell in patients with chronic rhinosinusitis with nasal polyps being treated with dupilumab. The main questions it aims to answer are: 1. Does obstruction of the olfactory cleft predict return of the sense of smell? 2. Do electrophysiological signals generated by breathing and sniffing behavior predict return of the sense of smell? Participants starting dupilumab will undergo assessment for their degree of olfactory cleft obstruction, and an electrophysiologic assessment of their olfactory cleft and be followed over 6 months of treatment with dupilumab.
