NCT06907680
The goal of this clinical trial is to assess the efficacy and safety of M-Gard supplementation for alleviating the symptoms of allergic rhinitis.
NCT05191186
Investigation of the clinical efficacy of 3 intralymphatic injections with grass pollen extract into inguinal lymph nodes on combined symptom-medication scores during grass pollen season in grass pollen allergic patients compared to placebo
NCT06061848
A national, multicenter, randmised double blind study with parallell arms. 360 patients with grass induced allergic rhinitis will be open randomised 1:2 to 3 years Grazax sublingual immunotherapy or 3 intralymphatic injections with ALK Alutard Timothy. In a second step, the ILIT group will be double blind randomised 1:1 to an intramuscular injection of Vitamin D Vicotrat or placebo, 4 week before the start of the intralymphatic treatment. The primary outcome measure is daily combined symptoms and medication scores during grass pollen season.
NCT06104293
The aim of this study is to determine the optimal concentration of grass pollen allergens inducing rhinoconjunctivitis in subjects allergic to grass pollen in ALYATEC allergen exposure chamber. Four concentrations of grass pollen allergen (Phl p 5) are tested during 3-hour exposures: 0, 30, 60 and 90 ng/m3.
NCT03290248
This is a Prospective, Controlled, Double Blinded, Single Center, Randomized, 3 Arm, Parallel Assignment, Phase 1b/2a Study to assess the safety, tolerability, and preliminary efficacy of B244 delivered as an intranasal spray in healthy volunteers and subjects with seasonal allergic rhinitis.
NCT04878237
IgE-associated allergy is a hypersensitivity disease affecting more than 40% of the population in industrialised countries. Recently the kinetics of change of clinical and immunological parameters (e.g. nasal blockage and cytokine profiles) in response to allergen exposure have been described. Additionally through recent placebo controlled studies it has become clear that the response of certain cytokines can not only be triggered by allergen exposure but also mechanically e.g through the insertion of nasal swabs for collection of cytokines. However it is not clear to what extent the mechanically triggered cytokine responses may differ between healthy, allergic and asthmatic patients who have been shown to have different cytokine profiles in their nasal secretions and varying impairment of their respiratory epithelium. As collection devices for nasal secretions are frequently used in clinical studies, the investigators aim to assess the impact of mechanical stimulation by frequent cytokine sampling on the cytokine profile.
NCT04700852
This study is a proof o concept aiming to determine the efficacy of Puressentiel nasal protective spray (PNPS) in patients with allergic rhinitis. Cross over study, with a nasal provocative test (NPT) in patients with allergic rhinitis sensitized to grass pollen. A day 0 (first NPT) the following outcomes are recorded: allergic Rhinitis control test (ARCT) and Inspiratory nasal peak flow (INPF) before and 30 min after the NPT. Nasal lavage is performed 30 min after the NPT and 3 cytokines (IL4, IL5 and IL13 are measured by ELISA. An other NPT is performed at day 30 and the same outcomes measured. 30 min before NPT 2 nasal sprays of PNPS are administered in each nostril in a randomized manner and cross over, the patient being is own control. The primary outcomes ins the IL4, IL5 and IL13 concentrations in the nasal lavage. ARCT and INPF are the secondary outcomes.
NCT04210193
15 patients with moderate to severe allergic rhinitis against grass were recruited and enrolled in the study. They received three open label intralympatic grass allergen injections with the dose 1000 SQ-U each and with one month interval. The next year the patients were randomized double blind to an active or placebo booster injection of 1000 SQ-U before the pollen season. Grass specific IgG4 levels were measured before and at various time ponts after treatment.
NCT01953471
Prospective multi-center study carried out in France involving patients with allergic rhinitis. Study in usual care where no specific diagnostic or therapeutic procedure is required. The patients will be asked to fill in Questionnaires on a daily and weekly basis.
NCT00955825
The purpose of the study is to assess the efficacy and safety of 300 IR sublingual tablet of grass pollen allergen extract compared to placebo in adult patient with allergic rhinoconjunctivitis.
