Active clinical trials for "Nasal Polyps"

This is a cross-sectional study of up to 100 subjects who are undergoing clinically indicated sinus procedures to treat chronic rhinosinusitis. Participants will be asked to donate leftover sino-nasal secretions, sino-nasal tissue and blood as well as undergo partial characterization. As optional extensions of the main study, participants may also undergo a biopsy of extra sino-nasal tissue for additional tissue analysis and/or a more detailed characterization visit performed in the UCSF Airway Center Research Center (ACRC).

Patients with severe or difficult-to-treat asthma represent a small amount of total asthmatic patients, but weight on the national health system for the costs of disease management. Chronic rhinosinusitis with nasal polyposis, which the Italian severe/uncontrolled asthma registry reported with a prevalence of 30%, represents a comorbidity that significantly impact lung function and asthma control in severe asthma. Recent evidence indicates that there is a consistent heterogeneity regarding mucosal alterations present in subjects with nasal polyposis involving different pathways: inflammatory cells, remodeling, T cell activation, local IgE production, alteration induced by interactions between microorganisms and epithelial cells.

Primary Objective: - To describe the clinical characteristics of participants with chronic rhinosinusitis with nasal polyps (CRSwNP) in terms of disease severity, Type 2 inflammation-related comorbidities (such as asthma and allergic rhinitis), other associated comorbidities, and treatments used in a real-world setting Secondary Objectives: Describe the progression in treatment outcomes at different visits (baseline, 3 months, 6 months, and 12 months). To assess the healthcare resource utilization of participants with CRSwNP in countries of the Gulf region (number of visits, emergency room (ER), surgery, etc).

Verapamil is an L-type calcium channel blocker(CCB) which has been shown to reduce inflammation in a variety of tissues. Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by eosinophilic inflammation as well as P-gp overexpression. A previous trial of oral Verapamil showed preliminary efficacy for the treatment of CRSwNP. The goal of this study is to evaluate the safety and efficacy of intranasal Verapamil in CRSwNP. The study was initially approved as a Phase Ib/II, but only the Phase Ib portion was completed as part of this protocol.

The purpose of this randomized controlled double-blinded trial is to determine if the addition of an oral antifungal to typical post-operative medical therapy can prevent or reduce the incidence of recurrence of nasal polyps in fungal sensitive patients with chronic rhinosinusitis with nasal polyps (CRSwNP).

The purpose of this study is to compare the effectiveness of intranasal Triamcinolone delivered through a bio-absorbable nasal dressing verses oral steroids and a saline soaked dressing, in the treatment and prevention of early nasal polyposis.

Fluticasone furoate is being studied to determine whether treatment with a topical nasal steroid, in patients with existing nasal polyps , can not only improve symptoms but also suppress the recurrence of clinically significant nasal polyp obstruction and prevent surgical intervention.

This study will evaluate the effect of CBP-201, rademikibart, in adult patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP).

The purpose of this study is to determine the most effective route to administer steroids to patients with chronic sinusitis, specifically a type of chronic sinusitis not associated with nasal polyps (CRSsNP). The investigators would like to better understand whether orally administered steroids results in superior results when compared with nasally sprayed steroids. The investigators propose to test the hypothesis that for patients with radiographically proven CRSsNP, routine medical therapy consisting of a short course of systemic corticosteroids is superior to topical corticosteroids for relieving inflammation and the symptoms of CRS.

Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is a sino-nasal chronic inflammatory disease that strongly affects patients' quality of life, especially in difficult-to-treat cases. In severe uncontrolled CRSwNP, the inflammation is mostly driven by a type 2 inflammatory pathway and its management has been rapidly changing during the last 2 years due to Dupilumab approval. It is a fully human monoclonal antibody that binds the alpha subunit of IL-4 receptors (IL-4Rα type 1 and type 2) to inhibit IL-4 and IL-13 signaling. So far, randomized clinical trials have assessed efficacy and safety of Dupilumab in a large number of patients, whereas evidences in real life clinical practice are limited to few monocentric series. Herewith, the investigators present a multicenter, observational nationwide retrospective real-life study with the aim to confirm the effectiveness and the safety of Dupilumab over the first year of treatment in a real life setting. The primary objective is to evaluate the volumetric reduction of polyps by measuring the variation of total Nasal Polyp Endoscopic Score (NPS). The secondary objectives are: the evaluation of changes in nasal symptoms, olfactory function and nasal obstruction the assessment of the patients' quality of life the recording of major and minor complications the evaluation of the response to the therapy, according to EPOS2020 criteria and EUFOREA2021 the assessment of efficacy based on concomitant disease (Asthma and ASA triad) the evaluation of potential predictors of clinical response to the therapy
