Filter by:Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E after exposure to allergens in atopic individuals. The typical symptoms of AR are paroxysmal sneezing, watery rhinorrhea, itching, and nasal congestion, which may be accompanied by ocular symptoms, including eye itching, tearing, redness, and burning sensation, which are more common in patients with hay fever allergies. Bronchial asthma is associated with bronchial asthma in 40% of patients with AR, suggesting a comorbid feature of allergic disease.
The ragweed Ambrosia artemisiifolia is spreading in northern Europe due to climate change. The pollen are considered highly allergenic and might trigger allergy symptoms at much lower concentrations than e.g. grass or birch pollen. This study aims to determine threshold concentrations for ragweed and birch pollen in patients with seasonal allergic rhinitis. Participants will be exposed in an allergen challenge chamber that was technically modified to maintain very low and stable pollen concentrations for several hours. The study design is adaptive, where the pollen concentrations are escalated or de-escalated based on interim analysis of resulting allergic symptoms.
The trial will be conducted as a prospective, randomized, multinational, multicenter, double-blind, placebo and active controlled trial in 4 parallel-groups of patients suffering from seasonal allergic rhinitis.
The primary goal is to investigate the efficacy of intralymphatic immunotherapy (ILIT) for the treatment of allergic rhinitis and allergic asthma due to sensitisation to grass pollen allergens. 60 patients with allergic rhinitis will be included and randomized to receive either Polvac (n=30) or placebo (n=30). All patients will receive three injections with 4-8 weeks interval. The injections into a inguinal lymph node is guided by sonography. Patients will record symptoms and medication use in the summer of 2022 and 2023.
PA9159 is a highly potent novel corticosteroid. The purpose of this study is to evaluate the safety, efficacy and characteristics of population pharmacokinetics of multiple dosing of PA9159 Nasal Spray in patients with seasonal allergic rhinitis.
The primary objective of this 5-year study is to demonstrate non-inferiority of children compared to adults by exploring long-term effectiveness after treatment with TA Bäume (trees) and TA Gräser (grass) following a perennial posology.
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.
Prospective, randomized, placebo-controlled, multicenter of 3 active treatment groups, compared to 1 placebo group, for the determination of the efficacy and safety of subcutaneous immunotherapy in patients with mild to moderate asthma and allergic rhinitis/rhinoconjunctivitis (intermittent or persistent) due to hypersensitivity to house dust mites (Dermatophagoides pteronyssinus and / or D. farinae) and grass pollen
