Active clinical trials for "Rhinitis, Allergic"

Allergic rhinitis(AR) is one of the most common allergic disorders throughout the world.The conventional therapies are effective in alleviating symptoms but the efficacy are limited and not persistent. Furthermonre, the cost and side-effect are known defects. A classical Chinese herbal formula, has been used for AR for centries. Our study purpose is to evaluate the clinical efficacy and safety of this formula verus placebo in perennial allergic rhinitis (PAR). Hypothesis: the classical herbal formula would improve the symptoms of PAR patients and change some immunological parameters in the peripheral blood when comparing with the placebo.

On-the-road driving performance of untreated seasonal allergic rhinitis patients during the allergic season (exposed) is compared to driving performance outside the allergic season (in winter, not-exposed).

The purpose of this study is to investigate the safety and effectiveness of ciclesonide nasal spray as compared with placebo (inactive substance) nasal spray in relieving symptoms of seasonal allergic rhinitis caused by pollen. Ciclesonide will be administered once during the exposure to ragweed pollen in a controlled environment. The study duration consists of a baseline period (up to 5 days) and a treatment period (1 day). The study will provide further data on safety and tolerability of ciclesonide.

The primary objective of this study is to compare the efficacy and safety of GW685698X 100mcg once daily (QD) aqueous nasal spray with vehicle placebo nasal spray in adult and adolescent subjects (12 years of age and older) with perennial allergic rhinitis (PAR).

The purpose of this study was to determine the efficacy and safety of the study drug compared to placebo for the treatment of subjects with perennial allergic rhinitis.

The primary objective of this study is to compare the efficacy and safety of GW685698X 100mcg once daily (QD) aqueous nasal spray with vehicle placebo nasal spray in adult and adolescent subjects (12 years of age and older) with perennial allergic rhinitis (PAR).

The purpose of this study is to determine the effect of an approved medication on the symptoms of perennial allergic rhinitis (an inflammation of the mucous membrane of the nose similar to that found in hay fever except that symptoms persist throughout the year), in patients who have a history of perennial allergic rhinitis.

The purpose of this study was to determine the effects of exercise at different temperatures on nasal blood flow and symptoms in allergic rhinitis patients.

The primary objective is to assess the reduction of allergic symptoms as measured by combined symptom and medication score (CSMS) during birch pollen season after a single dose of REGN5713-5714-5715 versus placebo.

The aim of the study is to assess the effect of polyvalent mechanical bacterial lysate (PMBL, Ismigen) on the clinical course of grass pollen-induced allergic rhinitis (using: total nasal symptom score, visual analogue scale, peak nasal inspiratory flow measurement) in children aged 5 to 17 and to assess changes in the concentration of iNKT cells under the influence of the therapy. Half of the 80 participants will receive PMBL while the other half will receive placebo.
