Active clinical trials for "Rhinitis, Allergic, Seasonal"

To compare the effects of fexofenadine HCl 180 mg, cetirizine 10 mg, and placebo on computerized scores derived from the Aeromedical Vigilance Task (AVT), a computerized objective measure of attention, accuracy and reaction time in healthy naval flight personnel. Specifically, the primary objective is to compare the AVT overall (average of the 18 blocks) mean change from baseline in total number of errors (commission errors + omission errors) between fexofenadine HCl and cetirizine 10 mg. Safety of these single-dose treatments also will be assessed.

The primary objective of this placebo-controlled EEC study is to determine the time to onset of action of ciclesonide, applied as a nasal spray (200 mg, once daily) in patients with SAR.

This is an 8 day, randomised, double blind, 3-way crossover trial of repeat doses of intranasal GSK256066 and fluticasone propionate in the Vienna Challenge Chamber in subjects with seasonal allergic rhinitis (SAR). Approximately 60 subjects will be selected for enrolment with the intention of acquiring at least 48 evaluable subjects. Laboratory safety assessments, 12-lead electrocardiograph (ECG), vital signs and adverse event enquiries will be made throughout the study. Nasal examination, symptom scores, nasal lavage, nasal scrape and allergen challenge assessments will also be performed at various time points throughout the study.

This is a double-blind, placebo-controlled, randomized single dose escalation study and a double-blind, placebo-controlled, randomised parallel group 14-days once daily repeat dose study to investigate safety, tolerability and pharmacokinetics of an intranasal H1/H3 dual antagonist compound in healthy male subjects.

This study will compare the effectiveness of QAV680 against placebo in treating the symptoms of seasonal allergic rhinitis in an Environmental Exposure Chamber.

The purpose of this study was to test the effectiveness and side effects of desloratadine (Aerius) in patients with hayfever. Patients took desloratadine once a day for 15 days. At the end of therapy, they scored how severe their hayfever symptoms were and how they responded to therapy. Side effects were recorded.

The objective of this trial is to assess the clinical efficacy of the modified extract (depigmented and polymerised with glutaraldehyde)of the subcutaneous injection of Phleum pratense pollen in the treatment of patients affected by allergic rhinitis/ rhinoconjunctivitis ( with or without episodic asthma) induced by hypersensitivity to grass pollen, evaluating the Score regarding Symptoms and consumption of the medication.

This will be a randomized, double-blind, placebo-controlled, parallel-group, multicenter study. After passing the initial Screening Visit, subjects will be in the environmental exposure chamber(EEC), a room with a controlled amount of ragweed pollen, for 4 hours each day on 4 consecutive days. At the last visit, subjects who have achieved a minimum Total Nasal Symptom Score (TNSS) will be randomized to receive either TOLAMBA or placebo treatments. Subjects will receive 6 weekly subcutaneous (under the skin) injections of the study drug. About three weeks after the last injection, subjects will be asked to be in the EEC for 2 consecutive days (Visits 11 and 12, Days 60 and 61). Approximately 3 weeks after Visit 12 (Day 61), the subjects will again be in the EEC for 4 consecutive days (Visits 13-16, Days 82-85). During all EEC visits, the subjects will be exposed to ragweed pollen at an average concentration of 3500 ± 500 pollen grains per cubic meter. Each EEC visit will last 4 hours. During each EEC visit, patients will be asked to record symptom scores for nasal and non-nasal symptoms at scheduled time points. The total duration of a subject's participation in this study is expected to be a minimum of 85 days.

The aim of the study is to investigate the trial models, Vienna Challenge Chamber (VCC), in and out of season, and Park Study in season and the clinical efficacy of repeat doses of fluticasone propionate in subjects with seasonal allergic rhinitis.

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.
