Active clinical trials for "Rhinitis, Allergic, Perennial"

This is a study to evaluate the efficacy and safety of desloratadine (MK-4117) in Japanese participants with perennial allergic rhinitis. The primary hypothesis is that desloratadine is superior to placebo after 2 weeks of treatment with regard to change from baseline in Total Nasal Symptom Score among Japanese participants with perennial allergic rhinitis.

6-month safety extension study in subjects who have completed Study 060-633 (NCT00953147). Evaluating the long-term safety of ciclesonide HFA nasal aerosol 160 μg administered once-daily in patients with Perennial Allergic Rhinitis.

This is a single-centre, randomised, double-blind, four-period, incomplete block, crossover study, with 8 days repeat dosing of intranasal Fluticasone Propionate (25, 50, 100, 200ug) and/or placebo in the Vienna Challenge Chamber in subjects with allergic rhinitis.

The purpose of this study is to determine if two allergy medications are more effective than placebo.

This is a multicenter, randomized, double-blind within the dose level, parallel group comparison of mometasone furoate nasal spray in subjects with perennial allergic rhinitis to examine the minimal effective dose, the recommended dose, and the dosing regimen.

To assess the safety of long-term use of cetirizine dry syrup in children with perennial allergic rhinitis.

There has been considerable debate over the last 30 years about the interaction between asthma and parasitic infection. It has been suggested that at least part of the reason for the increasing prevalence of asthma in the developed world is a decrease in parasite infections resulting from improved living conditions with economic development. Our previous studies in Ethiopia suggest that hookworm infection may be particularly important in this process. To establish definitively whether parasites can protect against allergic disease, and specifically asthma, ultimately requires a randomised clinical trial of parasite infection in patients with asthma. We, the researchers at the University of Nottingham, have completed a study in normal volunteers to establish the dose of hookworms necessary to generate infection at the level shown to be protective in population surveys, and shown that infection is well tolerated. We now propose two randomised placebo-controlled double blind clinical trials. The first will test the effectiveness of hookworm infection in reducing symptoms in allergic patients with rhinitis, and will also serve to allow us to check the likely safety of hookworm infection in asthma. Assuming that the results of this study are favourable, we will then carry out a trial of hookworm infection in asthma. We will also take the opportunity during both of these studies to investigate the cellular mechanisms of the effect of hookworm infection on the immune system.

The primary objective of the study was to characterize the difference in prepubescent growth velocity in children 3 to 9 years of age with perennial allergic rhinitis (PAR) treated with triamcinolone acetonide (TAA) nasal spray (NASACORT® AQ 110 μg treatment group) or placebo (NASACORT® AQ placebo group) for 12-months. The secondary objectives were to compare the following in prepubertal participants treated with TAA nasal spray versus placebo: the 24-hour urinary free cortisol levels and the cortisol/creatinine ratio (to measure the Hypothalamic-Pituitary Adrenal [HPA] axis function) the rate of treatment-emergent-adverse-events (TEAE) global efficacy rated by the investigator and the participant separately the rate of use of rescue medication during the study

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.

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.
