Filter by:This study is designed to assess the effectiveness of mometasone furoate nasal spay (MFNS) once daily (QD) compared with placebo in subjects with seasonal allergic rhinitis (SAR) in reducing the total nasal symptom score and the total ocular symptom score.
Chitin microparticles (CMP) has been demonstrated in animal studies that have modelled allergic rhinitis to be effective against a wide range of common respiratory allergens. It is an immuneenhancer. The primary purpose of the study is to demonstrate safety in a first into man study on 24 human volunteers. The secondary objective is to demonstrate efficacy by chosing subjects that demonstrate a response to a nasal allergen challenge using grass pollen. The subjects are being given increasing doses of CMP, supplied as a nasal spray, for 7 days followed by a nasal allergen challenge with Timothy Grass Pollen extract. Over this period nasal symptom scores, eosinophil counts and cytokine measurements will be performed.
The primary objective of this study is to compare the nighttime symptom relief of fluticasone furoate nasal spray and oral fexofenadine
This study is in patients with seasonal allergic rhinitis (SAR) and will compare the effect versus placebo of repeat doses of intranasal GSK256066 using the Vienna Challenge Chamber. GSK256066 is a potent and highly selective phosphodiesterase-4 (PDE4) inhibitor, currently in development by GSK for the treatment of allergic rhinitis, asthma and COPD. Subjects will be selected on the basis that they display a defined moderate response to the pre-determined dose used. This study aims to explore the actions of repeat doses of intranasal GSK256066 in patients with Seasonal Allergic Rhinitis in the Vienna Challenge Chamber compared to placebo. 12-lead ECG, vital signs and adverse event enquiries will be made throughout the study. Nasal examination, symptom scores (TNSS), nasal lavage, nasal scrape and allergen challenge assessments will also be performed at various time points throughout the study.
This study will assess the effects of Imatinib on allergic inflammation following repeated nasal allergen challenge in subjects with seasonal allergic rhinitis sensitive to Timothy grass pollen.
This is study of LMC, phenylephrine, and placebo in subjects with SAR. There are three visits: At Visit 1, subjects will be evaluated for participation and, if they qualify, will attend Visit 2 for priming. At Visit 2, ragweed pollen will be fed continuously and dispensed into the environmental exposure unit to induce an allergic reaction. Pollen counts will be monitored and recorded. During the priming visit(s), subjects will be evaluated to determine if they qualify. If qualified, they will return for Visit 3, where ragweed pollen will be fed continuously and dispensed into the environmental exposure unit to induce an allergic reaction. Pollen counts will be monitored and recorded as in the Priming Session. Subjects will complete symptom evaluations and if qualified, they will receive study medication and remain in the environmental exposure unit where symptoms will be evaluated for 8 hours after dosing. PNIF will be evaluated only during the treatment session. Four nasal symptoms (rhinorrhea, nasal congestion, sneezing, and nasal itching) and three non-nasal symptoms (itching/burning eyes, tearing/watery eyes, and itching of ears/palate) will be evaluated. Adverse events will be collected throughout the study to assess safety and tolerability, and vital signs will be collected at Visit 1 and at the end of Visit 3.
To show that treatment with SUBLIVAC® Grasses is clinically effective by means of reduction in allergic symptoms and/or use of allergic symptomatic medication in subjects suffering from IgE mediated allergic complaints triggered by grass pollen.
This is a randomized, double blind, active and placebo controlled, 4 way crossover study in patients with seasonal allergic rhinitis. Patients will receive a single dose of bilastine 20 mg, Cetirizine 10 mg, Fexofenadine 120 mg, and placebo in the Vienna Challenge Chamber.
The purpose of this trial is to determine the safety, efficacy and tolerability of two doses of the study drug compared to placebo for the treatment of subjects with seasonal allergic rhinitis.
This study will investigate the effectiveness of desloratadine in treating subjects with allergic rhinitis (AR) who meet the criteria for intermittent allergic rhinitis.
