Filter by:Although it is well known that the presence of uncontrolled inflammation in upper airways may compromise the control of asthma and may favor the progression of asthma toward more severe grades of disease, few studies addressed whether therapies aimed to control both upper and lower airway inflammation may be more effective in controlling asthma. Markers of oxidative stress and of inflammation such as Nitrotyrosine and IL-5 are increased in the airways of children with atopic asthma and correlated with the levels of oral and nasal FeNO, and with the grade of atopy. We hypothesize that the treatment with Beclometasone nebulized with a facial mask (for treating both upper and lower airways) will be able to reduce the production of oxidants as well as of IL5 in both districts thus promoting clinical and functional improvements in mild intermittent asthmatic children. The results provided by this study will contribute to further clarify the relationship between nasal and bronchial inflammation.
What happens in the nose during an allergic reaction? Are there changes that a new drug could treat? What is the best way to test new drugs?The response of the nose to being exposed to cat allergen in someone who is allergic to cats. Symptoms, level of nasal blockage and cell and chemical changes that occur in the nose will be studied before and after being exposed to cat allergen. The investigators will also to see if giving repeated doses of allergen increases the response.Allergic rhinitis is a very common illness. There are over 500 million patients worldwide. It can increase the severity of associated asthma. Currently available drugs do not completely treat the symptoms. New treatments need to be found. A way of testing these drugs is very important. This study will investigate causes of the symptoms that occur in allergic rhinitis. It will also validate a proposed model to test new drugs. the Study Hypothesis is that a model of nasal allergen challenge shows an increased response (priming) with repeat challenges as determined by changes in nasal peak inspiratory flow.
This study will determine the capacity of more frequent dosing of QAV680 to suppress allergic inflammation. The study will investigate the paradigm of multiple receptor antagonism in allergic disease by combining QAV680 with a second generation H1 histamine receptor antagonist to assess possible additive or synergistic anti-allergic effects of the two compound classes.
The aim of this study is to investigate the immunomodulatory potential of Isolated Plasmacytoide Dendritic Cells (pDCs) and Regulatory T-cells (TREGs) isolated with clinical grade magnetic bead isolations techniques (MACS®) on the antigen presenting cell-induced proliferation of lymphocytes after allergen uptake in an in vitro cell culture system.
The purpose of this study is to evaluate the onset of action of fluticasone furoate nasal spray compared to olopatadine nasal spray and placebo nasal spray in reducing nasal allergic signs and symptoms following ragweed exposure in the Allergen BioCube (ABC) after single dose administration and six consecutive days of treatment.
The purpose of this study is to determine the safety and effect of CAL-263 in subjects with allergic rhinitis.
After a nasal allergen challenge it should be possible to measure markers of inflammation that may be useful to assess the properties of future drugs. If these markers are reproducible and impacted by the study drugs they could be useful for future drug development.
Investigation of the effect of Grazax (grass tablet) on asthma prevention in children with grass pollen allergy
This study investigates the safety of two up-dosing regimen. The safety of PURETHAL Grasses will be evaluated in a rush regimen (maximum dose reached in 3 injections during 2 weeks) compared to the conventional regimen (maximum dose reached in 6 injections during 5 weeks). The primary parameter will be the proportion of patients who experience systemic reactions > grade I within 24 hours after injection or who need more than 2 additional injections during the up-dosing phase until the maintenance dose has been reached. It is expected that up-dosing PURETHAL Grasses according to the rush regimen is as safe as using the conventional regimen.
The primary objective of this study is to evaluate the clinical efficacy of the drug Cloratadd D ® (loratadine + pseudoephedrine sulfate - EMS S/A) compared to the drug Claritin D ® (loratadine + pseudoephedrine sulfate - Schering Plough) in patients with allergic rhinitis by quantification of the scores of clinical parameters (signs and symptoms) and laboratory (nasal flow) down through time.
