Active clinical trials for "Rhinitis, Allergic, Seasonal"

The purpose of this study is to determine if two allergy medications (azelastine and fluticasone) are more effective than placebo or either medication alone (azelastine or fluticasone)

The Purpose of this study is to determine if one allergy medication (0.15% azelastine hydrochloride) is more effective than Placebo alone

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

Investigate safety/tolerability after a single dose intranasal administration of AZD8848 comparator placebo to healthy male volunteers and seasonal allergic rhinitis male patients out of season

The trial will evaluate the nasal congestion symptom relief of the approved 10 mg phenylephrine (PE) dose and the higher 20 mg, 30 mg, and 40 mg PE doses compared with placebo in participants with histories of seasonal allergic rhinitis, using loratadine as background medication.

Safety and efficacy of recombinant birch pollen allergen in the treatment of allergic rhinoconjunctivitis

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).

Ragweed MATAMPL has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to ragweed pollen (hay fever). This novel formulation is designed to provide a vaccine that will be efficacious with only four escalating dose injections administered before the start of the pollen season. In this Follow-up Study the Efficacy will be assessed by exposing allergic subjects to Ragweed pollen in an environmental exposure chamber EEC. Patient symptomatic response to pollen and patient quality of life in the EEC will be determined. Patients who previously completed two EEC portions of study Ragweed MATAMPL 204 and who had been treated with either Ragweed MATA MPL or Placebo before the 2005 ragweed season will be enrolled.

This study was designed to compare the efficacy and safety of an investigational nasal spray compared with placebo nasal spray and commonly used drug 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. Typical symptoms are sneezing, nasal congestion and pruritus, rhinorrhea, and pruritic, watery, red eyes.

This is a randomised, double-blind, placebo-controlled 4-period cross-over study to assess the efficacy and safety of repeat dose intranasal GSK1004723 (1000µg), oral GSK835726 (10mg) and cetirizine (10mg) in the environmental challenge chamber in subjects with seasonal allergic rhinitis.
