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.
An increasing number of people have an allergy to birch pollen, which manifests itself as Springtime hayfever. Some will also have cross-reactions to fruits, vegetables and nuts, a condition known as Oral Allergy Syndrome (OAS). Research has demonstrated that the most effective method of diagnosing this problem is by taking a good clinical history and performing skin prick tests using fresh foods. The aim of the study will be therefore to investigate the prevalence of OAS in a birch-sensitive population using a simple screening tool and establish the range of foods involved. The objective will be to maximise effective treatment for the patients in our large respiratory allergy clinic by using the screening tool to identify patients with OAS and advise them on the usual foods involved. A further objective will be to use the data to discover if there are any patterns of particular foods involved in OAS in UK sufferers. The study hypotheses are therefore that there is a high prevalence of oral allergy in people with birch pollen allergy; the best way of diagnosing the problem is by using a screening tool and that there is a core set of foods that are commonly involved in OAS in patients seen in the allergy clinic.
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.
This study seeks to compare patients with vasomotor rhinitis ("perennial nonallergic rhinitis," "idiopathic rhinitis") with normal controls with respect to their nasal physiologic reactivity to cold air challenge. Ten vasomotor rhinitis (VMR) patients with nasal symptoms triggered predominantly by cold air, four VMR patients with symptoms triggered predominantly by chemicals, and ten nonallergic, non-rhinitic control subjects will be studied.
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.
This study will investigate the effectiveness of desloratadine in treating subjects with allergic rhinitis who meet the criteria for persistent allergic rhinitis (PER)
The objective of this study is to determine whether there is a relationship between interferon-gamma levels and the incidence of viral respiratory infections in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care (nasal steroids, antihistamines) over a 1-year period. The hypotheses to be tested are 1) interferon-gamma levels will be significantly increased 3, 6, 9 and 12 months in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care, 2) the incidence of viral respiratory infections will be reduced at 3, 6, 9 and 12 months in allergic children treated with allergy immunotherapy as compared to those treated with standard medical care.
