Active clinical trials for "Rhinitis, Allergic"

This study will evaluate whether multiple nasal antigen challenges with dust mite allergen produces increases in nasal symptoms and local allergic inflammatory cells in the nose and the blood.

We hypothesize that those patients with purely seasonal allergic rhinitis will decongest better than those subjects with another cause contributing to their symptoms. These latter patients will not improve as well on an intranasal steroid as those who decongest well, potentially explaining the 60% response rate in prior studies.

Non-interventional, open-label, single group, multicentric post-marketing surveillance to monitor the safety and effectiveness of AVAMYS nasal spray administered in Korean patients according to the prescribing information. AVAMYS is a registered trademark of the GSK group of companies.

The investigators aimed to explore miRNA-155 change in response to sublingual immunotherapy (SLIT), probiotics and combined treatment with SLIT and probiotics in AR children.

The study will assess the effectiveness of AIT treatment in real clinical practice in Germany.

Objective Seasonal allergic rhinitis (SAR) is a common disease in childhood and characterized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR patients. In addition, mometasone furoate nasal spray (MFNS) is a well-known therapeutic option. However, the literature provided no data about its effects in European children with SAR. Thus this study addressed this unmet need.

Correct methods and compliance of intranasal corticosteroid (INCS) is very important for the treatment of allergic rhinitis (AR). The animated cartoon-aided teaching of INCS administration was created to decrease workload of health care professionals. The aim of this study is to compare the achievement of the children with AR in using INCS between the group which were instructed by animated cartoon-aided teaching or oral presentation without demonstration.

The purpose of this study is to provide information on whether subjects with allergic rhinitis (AR) prefer the administration of fluticasone furoate (FF) nasal spray or mometasone furoate (MF) nasal spray based on how the products feel to the subjects when administered. This Phase IV interventional study is a multi-center, randomized, double-blind, single-dose, cross-over subject preference study to evaluate and compare patient preference for FF [(total dose of 110 microgram (mcg)] and MF (total dose of 200 mcg) nasal sprays in subjects with allergic rhinitis. These two commonly used nasal sprays use different actuation systems (FF nasal spray is side-actuated; MF nasal spray is top-actuated) and this study will evaluate whether this difference is reflected in the patient-assessed attributes of the two nasal sprays. The attributes or properties which are being assessed by the subjects for these nasal sprays include smell, taste & aftertaste, drip down the throat, run out of the nose, urge to sneeze, and irritation. The single-day study per subject comprises screening and all treatments and procedures. Eligible subjects will be randomized 1:1 to a cross-over treatment schedule so that all subjects receive both products. One group of subjects will have two sprays of FF administered in each nostril whilst a second group will have two sprays of MF administered into each nostril. At 30 (± 5) minutes after the first study medication treatment, the two groups will switch. The first group will then have two sprays of MF administered into each nostril and the second group will then have two sprays of FF administered into each nostril. After each treatment the subject will complete two sets of attributes questionnaires ('immediate' and 'delayed'). A subject-rated 'immediate' attributes questionnaire will be completed immediately following each treatment and a subject-rated 'delayed' attributes questionnaire will be completed approximately 2 minutes after each treatment. Upon completion of the second set of these two attributes questionnaires (immediate and delayed), a preference questionnaire will be completed by the subject. In the preference questionnaire, the subject states their preferred treatment, if any, for each of the product attributes, and finally states their overall preferred treatment, if any. There will be follow-up contact with the subject 24 (± 4) and 96 (± 4) hours after administration of the last treatment. The study is planned to enroll about 300 subjects.

Recently, a critical role in the development of allergic rhinitis (AR) has been attributed to the nasal epithelium. The airway epithelium forms a physical barrier, protecting the nasal mucosa and underlying organs from damage from contact with exogenous particles. The nasal epithelial barrier is primarily determined by the integrity of the airway epithelium, in which epithelial cells are connected to each other by complex network structures like tight junctions (TJs), ultimately sealing off the paracellular space. TJs consist of different transmembrane proteins including occludin, tricellulin, the claudin family, and junctional adhesion molecules. TJ form intercellular homodimers/heterodimers between neighboring cells. Scaffold adaptor proteins like cingulin and the zonula occludens family connect the transmembrane proteins to the actin cytoskeleton. Disturbed TJ function can facilitate the entrance of foreign pathogens and antigens into the submucosal layer, giving raise to allergic sensitization via increased access of allergens to the dendritic cells and/or inducing persistent inflammation via activation of mast cells and other inflammatory cells residing in the upper airways. Chronic disorders like allergic asthma, inflammatory bowel disease and atopic dermatitis have been linked to defective or altered TJ function. Recently, an impaired epithelial barrier function was found in patients with chronic rhinosinusitis with nasal polyps (CRSwNP), suggesting changes in TJ arrangement in the nasal cavity. CRSwNP presents a similar inflammation of the sinonasal cavities as found in AR patients, i.e. a Th2 cytokine driven inflammation with tissue eosinophilia. Nevertheless, the role of TJs and its regulation has not been investigated in AR.

Hypothesis: The UAS Immunotherapy protocol is efficacious and at least as efficacious as protocols described in the Allergy literature.
