Filter by:The purpose of this study is to find out if the bacteria present in the nose or sinuses of people with seasonal allergies changes during their allergy season. Another purpose of this study is to see if the bacteria present in the nose and sinuses of non-allergic people are the same as allergic people before the allergy season and if it changes during the season. Many bacteria are difficult to grow in the laboratory so the investigators are using analysis of DNA (the genetic material in cells) of the bacteria in the nose and sinus to find them. The investigators will be testing DNA of the bacteria only and not of the human subjects taking part in this study. This research is being done to help us understand how allergy affects bacteria in the nose and sinuses.
This is a 2-week, multicenter, randomized, double-blind, placebo-controlled, parallel group, efficacy and safety study of ciclesonide nasal aerosol administered once daily to male and premenarchal female subjects 6 to 11 years-old diagnosed with SAR.
This is a 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group, efficacy and safety study of ciclesonide nasal aerosol administered once daily to male and premenarchal female subjects 6 to 11 years of age with a diagnosis of PAR.
The study will assess the efficacy of OC000459 200 mg twice daily orally in comparison to placebo when subjects are challenged in the Vienna Challenge Chamber for 6 hours. This is a randomised, double blind, placebo controlled, two way crossover evaluation. There will be a screening period of up to three weeks and a washout period of at least one week between the two treatment periods. There will be a follow up one to three weeks after the last dose of study drug.
The purpose of this study is to investigate whether buffered hypertonic saline (BHS) is superior to normal saline (NSS) for improving mucociliary function and relief nasal symptoms in children with allergic rhinitis.
The purpose of this study is to evaluate the onset of action of fluticasone propionate nasal spray compared to placebo nasal spray in reducing nasal allergic signs and symptoms following ragweed exposure in the Allergen BioCube (ABC) after up to 14 days of at home dosing.
This study is designed to look at the affect of SB-705498 on rhinitis symptoms, as induced by capsaicin challenge
The objective of the present study is to characterize the dose-response relationship of PURETHAL® Mites with a nasal provocation test in order to support the optimal dose in terms of clinical efficacy and safety. For this purpose 5 groups of 50 patients, suffering from rhinitis or rhinoconjunctivitis due to House Dust Mite Allergy will be treated during 1 year. Before start, after 6 months of treatment and at the end of the study patients will be subjected to a nasal provocation test.
In a previous study the investigators found that many bakery workers were sensitized to storage mites, and many had rhinitis symptoms. The role of storage mites as an occupational allergen with clinical relevance has been questioned, and the investigators wanted to investigate whether a nasal provocation with a storage mite extract would trigger symptoms and objective signs of rhinitis in bakery workers and a control group.
This i a comparison of the efficacy ciclesonide nasal spray and levocetirizine, alone and in combination.
