Active clinical trials for "Rhinitis, Allergic"

This study is aimed at validating key therapeutic targets and biomarkers associated with allergic rhinitis. The therapeutic target expression will be investigated after a 7 day course of corticosteroid treatment followed by allergen challenge.

This will be a double-blind, randomized placebo-controlled study. 253 children were recruited and randomly assigned into one of 2 groups to receive either normal infant formula or formula with Bifidobacterium longum and Lactobacillus rhamnosus GG. The primary aim is to assess the effect of early administration (from birth) of probiotics on the incidence of allergic sensitization, eczema, asthma and rhinitis.

The purpose of this study is to investigate the safety and effectiveness of ciclesonide nasal spray as compared with placebo (inactive substance) nasal spray in relieving symptoms of perennial allergic rhinitis.

The purpose of this study is to evaluate the efficacy and safety of Magnólia nasal gel in the treatment of moderate-severe persistent or moderate-severe intermittent allergic rhinitis.

This study is to evaluate non inferiority of Eurofarma budesonide nasal spray x referral Astrazeneca budesonide. Half patients will receive Eurofarma medication and half patients will receive Astrazeneca medication. There is no placebo group.

Product information: Purotex is a textile treatment that uses five 100% natural bacteria or probiotics, selected for their ability to clean up house dust mite allergen along with other allergen types. Study design: Placebo-controlled: the effect of the Purotex impregnated mattress and pillow covers will be compared to untreated, classical bedding covers (placebo). Cross-over design: There will be 2 'treatment' arms. One arm (Arm 1) in which the subjects will first use the Purotex impregnated covers (Set A=Purotex) during 2 months (=period A) and, after a wash out period of 1 month, the untreated covers (set B=placebo) during 2 months (=period B). In the second arm (Arm 2), the subjects will first use the untreated set (set A=placebo) and, after a wash out period the Purotex impregnated covers (set B=Purotex). Randomized: The subjects will be randomly assigned to one of the 2 treatment arms. Double blind: both the subjects and the investigators will not know to which treatment arm the subjects are assigned. Study hypothesis: We want to investigate: if there is a reduced concentration of HDM allergen in Purotex covers compared to untreated covers in real life if patients with allergic rhinitis to house dust mite use the Purotex covers, they experience an improvement of their quality of life and sleep, and an improvement of their allergic symptoms and global discomfort

The investigators wish to evaluate the effects of decongestants like oxymetazoline and the lessening of this effect with time called 'tolerance'. The investigators will demonstrate a reversal of this tolerance with nasal steroids i.e. the investigators will show that nasal steroids protect against tolerance. This will tell us more on how the investigators can make this treatment effective and safe for patients suffering with allergic rhinitis.

This study will assess the safety and tolerability of multiple doses of VAK694 as well as change in symptoms and biomarkers in patients with seasonal allergic rhinitis

This is the first proof of concept study for OC000459 and is undertaken to assess the effects of the compound on the development of inflammatory cytokines in a model (nasal allergen challenge model) that is validated and clinically safe and easy to conduct. OC000459 will be compared with placebo in the study. The study will be a randomised, double blind, placebo controlled, crossover evaluation of the effect of OC000459 on cytokine secretion induced by nasal allergen challenge. Male subjects with a known history of allergic rhinitis and screening positive to allergen will be included. After dosing with OC000459 or placebo, nasal allergen challenge will be performed and measurements made in the nasal fluids. Nasal symptom scores will also be recorded. Safety parameters will be monitored throughout.

The purpose of this study is to determine the protective effect of an approved medication on asthma and allergic rhinitis (inflammation of the mucous membrane of the nose) upon exposure to cats.
