Active clinical trials for "Rhinitis, Allergic"

The purpose of this trial is to evaluate the efficacy and safety of an investigational drug in adult patients with allergic rhinitis.

The purpose of the study is to compare the efficacy and safety of an investigational nasal spray compared with placebo nasal spray in the treatment of seasonal allergic rhinitis. Allergic rhinitis is an inflammatory disorder of the upper airway that occurs following allergen exposure. The focus of this study, seasonal allergic rhinitis (SAR), is one type of allergic rhinitis that is triggered by the pollen from trees, grasses, and weeds. Commonly referred to as "hay fever", it is characterized by sneezing, nasal congestion and pruritus, rhinorrhea, and pruritic, watery, red eyes.

The purpose of this study is to assess the effect of an aqueous nasal spray investigational compound compared to placebo on the hypothalamic pituitary adrenocortical (HPA) axis system in adolescents and adults 12 to 65 years of age with perennial allergic rhinitis. This study can last up to 6 weeks and you will come to the clinic up to 7 times. Clinic visits include physical examinations, vital sign assessments, clinical laboratory assessments, ECGs and allergy skin testing. You will need to complete a daily diary card and spend the night in the clinic on 2 occasions to collect urine and blood samples over 24 hour periods.

The purpose of the study is to assess the efficacy comparability of cetirizine and levocetirizine, by comparing the effects of single intake of the two drugs to placebo in reducing symptoms of seasonal allergic rhinitis (SAR) in ragweed sensitive adult subjects exposed to ragweed pollen in an Environmental Exposure Unit.

This is a Phase 3, single-dose, investigator-blind, randomized, placebo-controlled, crossover study, conducted at a single site in Austria, outside of the normal grass pollen season. An allergic reaction will be induced by exposing subjects to grass pollen in the Vienna Challenge Chamber (VCC). Subjects will receive a single dose of each of the following treatments according to a randomization sequence: Phenylephrine 12 mg immediate-release capsule, pseudoephedrine 60 mg immediate-release tablet, and placebo capsule. There will be a minimum of a 5-day washout period between each treatment. Subjects will complete symptom evaluations throughout the study. The nasal decongestant effects of phenylephrine will be compared to those of placebo using the subjective symptom evaluations. The safety profile (adverse events and vital signs) of the treatments will also be evaluated.

This study will last up to 6 weeks. Subjects will visit the clinic up to 5 times. Certain clinic visits will include a physical examination, medical history review, and lung function tests. All study related medications and medical examinations will be provided at no cost to the subject. The drugs used in this study are approved for the age group under study.

This study was designed to assess safety of an investigational nasal spray in the treatment of perennial allergic rhinitis. Perennial allergic rhinitis is triggered by house dust, mite and mold etc. Typical symptoms are sneezing, nasal congestion and pruritus and rhinorrhea.

This is a Phase 4 randomized, placebo-controlled, parallel-group, single-center, double-blind study to evaluate the effects of mometasone furoate nasal spray (MFNS) in subjects with Sleep-disordered Breathing (SDB) associated with perennial allergic rhinitis (PAR) using Peak Nasal Inspiratory Flow (PNIF), Embletta device home-monitored cardiopulmonary evaluations, and rhinitis evaluations and questionnaires. Approximately 30 subjects 18 to 60 years of age with symptomatic PAR (with or without SAR) will be selected and randomized at one study site. The anticipated duration of subject participation in the study is approximately 39 days. Subjects who qualify at the Screening Visit will complete a 10-14 day run-in/screening period. Following the run-in period, subjects who meet the qualifications at the Baseline Visit will be treated with study medication for 4 weeks.

This study is in patients with seasonal allergic rhinitis(SAR)and will compare the effect versus placebo of repeat doses of intranasal GSK256066 using the Vienna Challenge Chamber. GSK256066 is a potent and highly selective phosphodiesterase-4 (PDE4) inhibitor, currently in development by GSK for the treatment of allergic rhinitis, asthma and COPD. Subjects will be selected on the basis that they display a defined moderate response to the pre-determined dose used. Opportunity to assess the efficacy of compounds versus placebo at maximal and trough plasma concentrations. This study aims to explore the actions of repeat doses of intranasal GSK256066 in patients with Seasonal Allergic Rhinitis in the Vienna Challenge Chamber compared to placebo. 12-lead ECG, vital signs and adverse event enquiries will be made throughout the study. Nasal examination, symptom scores (TNSS), nasal lavage, nasal scrape and allergen challenge assessments will also be performed at various time points throughout the study.

The purpose of this study is to find out if a new investigational vaccine, TOLAMBA™, is safe and effective in reducing the symptoms of ragweed allergy.
