Active clinical trials for "Rhinitis"

This study is designed to assess the effectiveness of mometasone furoate nasal spray (MFNS) once daily compared with placebo in subjects with seasonal allergic rhinitis (SAR) in reducing the total symptom score.

Controlled conditions of the EEU allow a reliable assessment of the efficacy and a determination of the action onset, action intensity and duration of effect of levocetirizine and cetirizine in order to establish the relative efficacy of these two drugs available for the treatment of SAR.

To Evaluate the Efficacy and Safety of Levocetirizine Versus Loratadine for Treatment of Seasonal Allergic Rhinitis

A series of allergy shots may reduce symptoms of seasonal ragweed allergies. This study will determine whether taking a drug called omalizumab (also known as Xolair) before getting the allergy shots is more effective than allergy shots alone or other treatments, such as prescription antihistamines.

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.
