Filter by:The relationship between otitis media with effusion (OME) and chronic rhinosinusitis with nasal polyposis (CRSwNP) remains unclear. A cross-sectional study of 80 consecutively presenting patients who were diagnosed with CRSwNP was conducted. The aim was to ascertain the prevalence of OME in CRSwNP patients, to determine whether the severity of CRSwNP affected OME, and to identify risk factors for OME in CRSwNP patients.
This is a 24-week randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of intranasal administration of 186 and 372 μg twice daily (BID) of OPN-375 in subjects with chronic Rhinosinusitis (CRS) without nasal polyps
A Phase 2a, randomized, double-blind, placebo-controlled, multi-center study to evaluate the efficacy, safety, pharmacokinetics (PK), and pharmacodynamics (PD) of GB001 compared with placebo over 16 weeks of treatment in patients with chronic rhinosinusitis with or without nasal polyposis (NP).
CRS remains a common challenging clinical entity due to variable phenotypes with different underlying mechanisms that lead to persistence or recurrence polyps. The eosinophils dominant inflammation was considered as a major pathological hallmark and challenges of CRS with nasal polyps (CRSwNP). Differentiate surgical approaches towards eosinophilic CRSwNP (eCRSwNP) should be addressed on the basis of the inflammatory endotypes. eCRSwNP has been recognized as the most easily relapsed type of CRS, and the combination of asthma increases the difficulty of treatment. Till now there is no recognized surgical strategy for eCRSwNP with asthma.
Prevalence of aspirin-exacerbated respiratory disease (AERD) is 16% amongst patients suffering from chronic rhinosinusitis with nasal polyps (CRSwNP). The mechanisms underlying the observed dysregulation of pro and anti-inflammatory pathways in AERD are still not fully understood. To address this and also to identify potential factors characterizing the disease the investigators plan to prospectively collect blood samples, nasal secretions as well as nasal biopsies from allergic, non-allergic and AERD patients suffering from CRSwNP. Initially, polyps of aforementioned patients will be subjected to RNA sequencing analysis using microarray technology. Once distinct factors are identified in nasal polyp tissue, their presence will be assessed in nasal secretions and serum of the respective patients to investigate their potential role as biomarkers. Furthermore presence of these parameters will be confirmed in situ in biopsies by confocal microscopy. Knowledge about factors differently upregulated in polyp tissue from AERD may contribute to a better understanding of the underlying mechanism of the disease.
This is a 24-week randomized, double-blind, placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of intranasal administration of 186 and 372 μg twice daily (BID) of OPN-375 in subjects with chronic rhinosinusitis (CS) with or without nasal polyps.
Asthma is often associated with various comorbidities that may influence its clinical expression. Among those, chronic rhinosinusitis with nasal polyposis (CRSwNP) is observed in 5% of cases. Asthmatic patients with CRSwNP appear to have more severe and poorly controlled asthma, as well as greater bronchial and systemic inflammation, especially those using inhaled corticosteroids as control medication. However, this remains to be validated. In the last decade, there has been interest labeled for phenotyping of asthma and CRSwNP. However, there is scarce data on the phenotype of asthma with CRSwNP. This study aims to describe the phenotype of asthmatic patients with CRSwNP according to the clinical, physiological and inflammatory characteristics and whether there is a more severe phenotype related to the dose of inhaled corticosteroids and the percentage of induced sputum eosinophils.
The study will evaluate the effect of ACT-774312 on the nasal polyps and will assess the safety and tolerability of ACT-774312 in the patients with bilateral nasal polyposis
A Phase 3b Proof-of-Concept study to evaluate the ability of fevipiprant 150 mg and 450 mg, compared with placebo, as add-on to nasal spray standard-of-care (SoC), in reducing endoscopic nasal polyp score in adult (≥ 18 years) patients with nasal polyposis and concomitant asthma.
This is a 24-week, open-label, multi-center study designed to assess the efficacy and safety of OPN-375 186 μg twice a day in subjects with nasal polyps using Nasoendoscopic video. The total planned number of subjects is approximately 10, with each subject receiving OPN-375 186 μg twice a day.
