Active clinical trials for "Rhinitis, Allergic, Seasonal"

To compare the clinical efficacy of levocetirizine 5 mg and montelukast 10 mg, administered once daily during two consecutive days, on symptoms of seasonal allergic rhinitis occurring in subjects exposed to ragweed pollen in an environmental exposure unit.

This is a Phase 3, randomized, parallel-group, multicenter, double-dummy, double-blind study with a screening period. Subjects will receive one of the following three treatment groups for 15 days: loratadine 10 mg/montelukast 10 mg combination, pseudoephedrine 240 mg, or placebo. The primary objective of this study is to assess the efficacy of the combination of loratadine/montelukast, a once-daily tablet containing 10 mg loratadine and 10 mg montelukast, compared with placebo in subjects with seasonal allergic rhinitis (SAR) in relieving the symptom of nasal congestion. The safety profile of combined loratadine/montelukast relative to placebo and pseudoephedrine will also be evaluated.

The aim of this study is to assess the efficacy on nasal congestion and other allergic symptoms and the onset of action of an oral combination of cetirizine and pseudoephedrine in comparison to the single substances under controlled pollen exposure in an Environmental Challenge Chamber (ECC).

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.

The purpose of this study is to determine the effect of an approved medication on the symptoms of seasonal allergic rhinitis (a seasonal variety of inflammation of the mucous membrane of the nose) in patients who are experiencing symptoms of seasonal allergic rhinitis and asthma.

This is a study of the effectiveness and safety of a new nasal spray for the relief of the symptoms of seasonal allergies. The agents being compared are: R926112 (a novel anti-allergy medicine), Beconase (beclomethasone dipropionate, an established FDA approved steroid treatment), and an inactive placebo. The study hypothesis is that R926112 will be superior to placebo at the end of a week of testing and evaluation. The study does not have the power to determine how R926112 compares to Beconase.

To evaluate the therapeutic equivalence of the lest formulation of Mometasone Furoate Nasal Spray, 50 mcg to the marketed formulation NASONEX® (mometasone furoate monohydrate) Nasal Spray, 50 mcg/actuation in patients with seasonal allergic rhinitis

This study will investigate usability and compliance related to rhinix nasal filters for the treatment of seasonal allergic rhinitis (hay fever) during the natural grass pollen season in Denmark.

The purpose of this study is to investigate if ONO-4053 relieves symptoms of allergic rhinitis in seasonal allergic rhinitis subjects exposed to pollen under controlled conditions.

This study will evaluate the ability of montelukast to improve the signs and symptoms of seasonal allergic rhinitis compared with loratadine and placebo.
