Filter by:The aim of the study is to determine the efficacy and safety of ciclesonide nasal spray in children with seasonal allergic rhinitis. Ciclesonide will be administered intranasally at two dose levels once daily. The study consists of a baseline period (1 to 3 weeks) and a treatment period (2 weeks).
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.
To compare the clinical efficacy of levocetirizine 5 mg and montelukast 10 mg on symptoms of seasonal allergic rhinitis occurring in subjects exposed to ragweed pollen in an environmental exposure unit.
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 the first proof of concept study for OC000459 and is undertaken to assess the effects of the compound on the development of inflammatory cytokines in a model (nasal allergen challenge model) that is validated and clinically safe and easy to conduct. OC000459 will be compared with placebo in the study. The study will be a randomised, double blind, placebo controlled, crossover evaluation of the effect of OC000459 on cytokine secretion induced by nasal allergen challenge. Male subjects with a known history of allergic rhinitis and screening positive to allergen will be included. After dosing with OC000459 or placebo, nasal allergen challenge will be performed and measurements made in the nasal fluids. Nasal symptom scores will also be recorded. Safety parameters will be monitored throughout.
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).
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.
The purpose of this study is to evaluate the safety and tolerability of ciclesonide nasal spray for long term use in relieving symptoms in perennial allergic rhinitis.
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.
Long term safety (52 weeks) of GW685698X on the nasal mucosa via nasal biopsy with an active control group (Nasonex®) and a healthy volunteers control group in subjects 18 years old with perennial allergic rhinitis . Allergic rhinitis is an inflammatory disorder of the upper airway that occurs following allergen exposure. Perennial allergic rhinitis is triggered by house dust mites, animal dander, etc., possibly causing symptoms year-round including nasal congestion, rhinorrhea and/or nasal itching.
