Active clinical trials for "Rhinitis, Allergic, Seasonal"

The purpose of this trial is to determine the safety, efficacy and tolerability of two doses of the study drug compared to placebo for the treatment of subjects with seasonal allergic rhinitis.

Chitin microparticles (CMP) has been demonstrated in animal studies that have modelled allergic rhinitis to be effective against a wide range of common respiratory allergens. It is an immuneenhancer. The primary purpose of the study is to demonstrate safety in a first into man study on 24 human volunteers. The secondary objective is to demonstrate efficacy by chosing subjects that demonstrate a response to a nasal allergen challenge using grass pollen. The subjects are being given increasing doses of CMP, supplied as a nasal spray, for 7 days followed by a nasal allergen challenge with Timothy Grass Pollen extract. Over this period nasal symptom scores, eosinophil counts and cytokine measurements will be performed.

The primary objective of this study is to compare the nighttime symptom relief of fluticasone furoate nasal spray and oral fexofenadine

This study will assess the effects of Imatinib on allergic inflammation following repeated nasal allergen challenge in subjects with seasonal allergic rhinitis sensitive to Timothy grass pollen.

This study will hope to show that by relieving the participant's nasal symptoms of seasonal allergies using mometasone furoate nasal spray, the participant will obtain a better quality of night-time sleep, which in turn, causes less daytime sleepiness so that he/she can function productively during the day.

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 purpose of this study was to identify the lowest dosage of mometasone furoate nasal spray (MFNS) that provided adequate efficacy with an acceptable safety profile for children (ages 6-11) with seasonal allergic rhinitis (SAR). The MFNS dose levels of 25, 100, and 200 mcg QD were compared with beclomethasone dipropionate (BDP), as an active control, and placebo.

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 this clinical phase I single centre, randomized, double-blind, placebo-controlled study with open comparator is to investigate tolerability and safety as well as the immunological effects of BM41 in comparison to placebo (double blind) and to a standard subcutaneous immunotherapy Alutard SQ (open) in birch allergic patients.

The objective of this study was to evaluate the efficacy, safety, and dose-response of ASP4070 vaccinated in patients with cedar pollinosis.
