Filter by:Advances in understanding the pathophysiology of asthma development and severity have pointed towards a prominent role of the bronchial epithelium, especially in more chronic and severe disease. Studies suggest that airway eosinophilic inflammation in asthma is linked to epithelial injury and structural changes of the airways, co called airway wall remodeling. Together the chronic airway inflammation and remodeling are associated with bronchial hyperresponsiveness, fixed airflow obstruction or progressive loss of lung function and clinical severity of asthma. Chronic rhinosinusitis with nasal polyps (CRSwNP), is another respiratory inflammatory disease often co-existing with severe asthma, sharing similar pathophysiology. The investigators hypothesize that epithelial barrier integrity may play a role in the pathophysiology of severe eosinophilic asthma and nasal polyposis and in response to anti-IL5 therapy of severe asthmatics, and that shedding of epithelial barrier proteins may be used as biomarker in the management of severe asthma. In order to study that, the investigators will conduct a prospective cohort study of adult severe asthmatics with/out CRSwNP, who live on the island of Crete, Greece and who meet the criteria for entering anti-IL5 treatment, as assessed by pulmonologist. The participants will be recruited with a convenience sampling in a period of 2 years, under real life conditions, and will be followed up for 1 year after treatment initiation. A control group of subjects diagnosed with nasal polyposis without severe asthma will be used. Eligible subjects will undergo clinical assessment with radiological (CT) and endoscopic investigations. Samples of serum, sputum, nasal secretions, as well as nasal and bronchial biopsies will be obtain for assessing clinicopathological differences among the 3 groups but also response to anti-IL5 therapy in SEA w/o CRSwNP.
TRL1068 is expected to eliminate the pathogen-protecting biofilm in Chronic Rhinosinusitis, thus making these bacteria substantially more susceptible to established antibiotic treatment regimens. This initial study is to assess overall safety and pharmacokinetics (PK) of TRL1068. The goal of the development program is to demonstrate effectiveness of TRL1068 in difficult to treat bacterial infections such as in CRS.
This is a multi-center, randomized, double blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, PK, PD, immunogenicity and preliminary efficacy of CM326 in patients with chronic rhinosinusitis with nasal polyps.
The objective of this study is to compare the effectiveness of batten grafts plus septoplasty and turbinate reduction (intervention arm) compared to septoplasty and turbinate reduction alone (control arm), both in terms of subjective and objective assessments.
This study will evaluate the efficacy and safety of depemokimab (GSK3511294) in participants with CRSwNP.
This study will evaluate the efficacy and safety of depemokimab (GSK3511294) in participants with CRSwNP.
The purpose of this study is to compare the efficacy and safety of rimegepant versus placebo in the acute treatment of chronic rhinosinusitis (CRS) with and without nasal polyps.
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
With a prevalence of 2-4% in western countries, Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is of major concern regarding its substantial impact on the social and physical quality of life. So far, endoscopic sinus surgery remains the treatment of choice when the first line of medical treatment with corticosteroid has failed. During the last 15 years, several studies have shown that CRSwNP is associated with a T helper 2 (T2) immune response leading to B cell release of IgE, mucosal recruitment of eosinophils from bone marrow via Interleukin (IL)-5, IL-4 and IL-13 mediated chemoattractant production. New biologic agents capable of blocking T2 cytokines have been developed in the field of eosinophil-associated diseases, shifting the paradigm of treatment for patients with CRSwNP. In the near future, endotype profiling with accurate biomarkers will be mandatory to tailor the treatment of nasal polyposis with specific biologic therapies. Herein we propose a prospective study monitoring medical records of CRSwNP patients who undergo biologic treatments. The objectives are to assess treatment efficacy on quality of life, to report clinical and biological criteria for prescription and to measure tolerance and compliance.
The purpose of this observational study is to describe the population of patients with SEA + NP who have been prescribed FASENRA and assess available clinical outcomes for both NP and asthma.
