Filter by:The purpose of this allergen challenge study is to assess the efficacy of IRL201104 compared with placebo in adult participants with seasonal allergic rhinitis.
Seasonal allergic rhinitis has multiple consequences: sleep disturbances, fatigue, depressed mood, impaired quality of life and productivity, and co-morbid conditions such as asthma, which affects one third of AR patients. In Europe, more than 150 million people suffer from allergic rhinitis and more than 25 million suffer from asthma. About 30% have uncontrolled rhinitis during exposure to allergens. The impact of allergic diseases on work productivity is estimated to be between 30 and 50 billion € per year in the EU. Studies show that pollution can play a role in the amplification of the response to inhaled pollen allergens by inducing morphological and functional modifications of nasal and bronchial epithelia, but also by inducing structural modifications of allergenic molecules. However, although data show that the symptoms of AR are aggravated by exposure to air pollution, this effect is not observed for all pollens. The study area is very exposed to pollens (with a significant presence of cypress pollen) and air pollution, and presents a prevalence of asthma of 17% while the national average is about 7%. The aim of this study is to establish, if they exist, links between pollens of various species, air pollution and symptoms of allergic rhinitis. The knowledge of these links will allow public authorities to set up prevention actions, and patients to better manage their allergic rhinitis on a daily basis.
The aim of this clinical phase I single centre, randomized, double-blind, placebo-controlled study with open comparator is to investigate tolerability and safety as well as the immunological effects of BM41 in comparison to placebo (double blind) and to a standard subcutaneous immunotherapy Alutard SQ (open) in birch allergic patients.
An open label, randomized, three-treatment, three-period, crossover, single dose study, to investigate drug-drug interaction and relative bioavailability between the fixed dose combination Azelastine hydrochloride / Beclomethasone dipropionate (140/100 μg Azelastine hydrochloride / Beclomethasone dipropionate) Nasal Spray, and Beclomethasone Dipropionate Nasal Spray (100 μg Beclomethasone Dipropionate) in the test vehicle, and the commercially available product, RinoClenil® Nasal Spray (100 μg Beclomethasone Dipropionate), in healthy subjects under fasting conditions.
Objective biomarker of allergic rhinitis severity is necessary for monitoring disease severity and response to treatment in clinical setting and for research. We believe that psychological factors are the missing link between patient-perceived severity of allergic rhinitis and objective biomarkers. In our pilot study, several psychological factors were studied in relation to patient reported outcomes for severity of allergic rhinitis.
The primary objective is to assess the reduction of allergic symptoms as measured by combined symptom and medication score (CSMS) during birch pollen season after a single dose of REGN5713-5714-5715 versus placebo.
PQGrass309 is aimed at exploring the expected average treatment effect of PQ Grass 27600 SU cumulative dose on symptom and medication score in a field setting. The study will enrol adult subjects with seasonal allergic rhinitis and/or rhinoconjunctivitis (SAR) induced by grass pollen exposure.
The purpose of this study is to analyze nasal samples for the presence of biomarkers of allergic inflammation as well as cold and flu infections, and compare these samples both in and out of an individual's active allergy season. 40 subjects who suffer from seasonal allergies will be recruited and seen both in and out of allergy season, and 10 healthy controls. Nasal epithelial lining fluid (NELF,) collected by placing small filter papers into the nostrils, blood for analysis and a cold/flu swab will be collected at each study visit.
This study is to assess the onset of action of fixed drug combination of azelastine hydrochloride and fluticasone propionate nasal spray (Dymista) in treating the nasal symptoms of seasonal allergic rhinitis (SAR) induced by an allergen challenge in an Environmental Exposure Unit (EEU).
This was a multicenter, uncontrolled, open-label, special drug use study to investigate the safety and efficacy of Xolair by collecting data in its clinical setting in patients with severe to most severe seasonal allergic rhinitis aged ≥ 12 years and < 18 years whose symptoms were inadequately controlled despite to conventional therapies and used Xolair.
