Filter by:Leukotrienes play critical roles in the inflammatory process in allergic rhinitis and bronchial asthma, therefore, anti-leukotriene therapy is part of treatment for asthma. However, not all allergic rhinitis accompanied with or without asthma treated with anti-leukotriene were effective. So it is critical to develop a method to identify the response subgroup. In this study, it is assumed that nasal physiological responsiveness to leukotriene nasal provocation test (NPT) is able to gain evidence on the effect of leukotriene on the development of allergic rhinitis and asthma, and is helpful to the use of anti-leukotriene agent. The purpose of the study is to establish the methodology and diagnostic value of leukotriene D4 (LTD4) nasal provocation.
This is an open label, randomized, 3-way cross-over, and repeat administration study in healthy male and female subjects. The purpose of the study is to determine the relative bioavailability of Fluticasone Furoate (FF) and Levocabastine (LEV), when each is administered alone and as FF/LEV Fixed Dose Combination (FDC).This study consists of Part A (in which 30 subjects including 12 Korean subjects will be enrolled) and Part B (in which 18 subjects will be enrolled). Each part will consist of three treatment periods separated by a minimum washout period of 14 days. In each treatment period, subjects will receive seven daily doses of one of the 3 treatments: FF, LEV or FF/LEV FDC, via an intranasal spray according to one of the 6 possible randomization sequences. The study will use an adaptive design with an interim review following Part A to confirm whether Part B is required.
This study will be a randomised, double blind, placebo controlled, 3-way, incomplete block crossover study to evaluate the effect of single and repeat doses of levocabastine, FF, placebo and a FDC of FF/levocabastine administration in AR subjects. The total expected study duration for each individual participating in the study will be a maximum of up to 20 weeks (including the screening and follow-up). This will be a three period study and subjects will be assigned to a sequence of three treatments. There will be a wash-out period of 14-28 days between two treatment periods. The rational for this study is to demonstrate proof of concept with the FDC of FF and levocabastine compared with each of the components administered alone.
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.
This study will be a randomized, double blind, placebo controlled, 3-way cross over design in allergic rhinitis subjects. Subjects will receive repeat doses of intra-nasal levocabastine for 7 days in each period and the duration of the study will be about 13 weeks. An Environmental Exposure Chamber (EEC) will be used in this study. The primary objective of the study is to investigate the non-inferiority effect of 7 days treatment with levocabastine on nasal symptoms elicited by an EEC when administered once daily (QD) compared with twice daily (BID). Also study will be conducted to investigate the superiority of effect of 7 days treatment with levocabastine (QD and BID) on nasal symptoms elicited by an EEC in subjects compared to placebo.
Allergic rhinitis (allergic inflammation of the nose) is a common medical condition which is known to seriously decrease quality of life, aggravate preexisting conditions particularly asthma, carry significant medical treatment costs and be responsible for reduced work productivity and lost school days. A significant symptom of the condition, nasal blockage, remains difficult to treat even when using nasal corticosteroids. Decongestant medications act on the blood vessels in the nose and have an immediate effect in clearing a blocked nose but if used for more than seven days a more severe rebound congestion of the nose develops. In this study, the investigators aim to assess the effects of doxazosin, a drug which is currently used to treat high blood pressure and symptoms of prostate enlargement, to find out if it has an effect on nasal blockage.
The study will assess the efficacy and safety of SPARC1310 when compared to placebo and active control
We hypothesize that ear acupressure will be effective in treating seasonal allergic rhinitis by changing the immune parameters and the psychological impact factors are associated with ear acupressure treatment outcome.
The purpose of this study is to investigate the safety and tolerability of different doses of sublingual tablets of house dust mite (HDM) allergen extracts in adolescents with house dust mite-associated allergic rhinitis.
This study investigates the safety of two up-dosing regimen. The safety of PURETHAL Birch will be evaluated in a rush regimen (maximum dose reached in 3 injections during 3 weeks) compared to the conventional regimen (maximum dose reached in 6 injections during 6 weeks). The primary endpoint of the sudy is the comparison of the proportions of the patients who have successfully reached the maintenance dose between the two treatment regimes. A similar previous study with PURETHAL Grasses has shown that the rush up-dosing scheme is as safe as the conventional up-dosing regime. Therefore it is expected that up-dosing with PURETHAL Birch according to the rush regimen is as safe as using the conventional regimen.
