Active clinical trials for "Rhinitis, Allergic"

To assess the reproducibility of the allergic response in the cat allergic subjects, measured as the change from baseline of the Total Nasal Symptom Score (TNSS) on the two challenge days.

An open label, randomized, three-treatment, three-period, crossover, single dose study, to investigate drug-drug interaction and relative bioavailability between the fixed dose combination Azelastine hydrochloride / Beclomethasone dipropionate (140/100 μg Azelastine hydrochloride / Beclomethasone dipropionate) Nasal Spray, and Beclomethasone Dipropionate Nasal Spray (100 μg Beclomethasone Dipropionate) in the test vehicle, and the commercially available product, RinoClenil® Nasal Spray (100 μg Beclomethasone Dipropionate), in healthy subjects under fasting conditions.

Allergic rhinitis is an IgE-mediated, inflammatory disorder of the upper airway that occurs following allergen exposure. Perennial Allergic Rhinitis (PAR) starts in early childhood and occurs all year around. It's caused by allergy to the aerosolised droppings of house dust mites and pet skin flakes (dander). Occasionally, indoor mould spores and, in rare cases, food allergy can be causes. Intranasal corticosteroids are highly effective medications for controlling the nasal symptoms that accompany allergic rhinitis. AVAMYS (TM) (fluticasone furoate aqueous nasal spray 100mcg) has been shown having effects on nasal symptoms of seasonal and perennial allergic rhinitis and on the ocular symptoms of allergic rhinitis and has been evaluated as effective and safe for treatment seasonal and perennial allergic rhinitis by FDA. It is speculated that AVAMYS (TM) is also effective and safe for Vietnamese patients. However before being used widely for patients across the country, AVAMYS (TM) should be proved that it is safe for Vietnamese patients. The objective of this study is to evaluate the safety of fluticasone furoate aqueous nasal spray 110mcg once daily in adults with PAR. This is a 6-week, open trial. A study center will be enlisted to recruit a minimum of 50 PAR subjects. At the visit 1, subjects who fulfill the inclusion criteria are eligible to be included in the group to self-administer intranasal treatment of fluticasone furoate aqueous nasal spray 110 mcg once daily for 6 week. The subjects are instructed to administer two sprays from the device into each nostril once daily every morning. Administration of the dose will be performed by alternately spraying one spray to each nostril followed by a second spray to each nostril. Subjects will not be permitted to take any anti-allergy or rhinitis medication during the screening or treatment period. Throughout the study, subjects will document their study drug administration/compliance, any medical conditions experienced, and any concomitant medications taken. All subjects are outpatients. The safety assessments include a summary of the frequency and type of clinical adverse events that occur during the study. In addition, hematology and chemistry analyses of blood samples are also implemented. A physical examination and nasal examination are also performed and vital signs collected. Twelve-lead ECGs are performed at all visits.

This clinical validation study is aimed at testing the efficacy of a new environmental challenge chamber (ECC) to induce symptoms of allergic rhinitis in patients allergic to house dust mite. The symptoms will be recorded on a validated symptom score as Total Nasal Symptom Score (TNSS), allowing for determine whether the challenge is dose dependent and reproducible.

The objective of this study is to evaluate the clinical equivalence of the test formulation of mometasone furoate anhydrous 50 mcg/actuation nasal spray (manufactured by Teva Pharmaceutical Industries, Ltd. and distributed by Teva Pharmaceuticals USA) to the marketed formulation Nasonex® (mometasone furoate monohydrate) nasal spray, 50 mcg/actuation (Schering) in patients with seasonal allergic rhinitis. In addition, the efficacy of both the test and reference nasal sprays will be compared to a placebo nasal spray and safety will be compared.

Subjects who have a clinical history of perennial rhinitis symptoms associated with dust exposure or not associated with other perennial allergens, will have a positive challenge with Dermatophagoides pteronyssinus. Subjects will be ppt negative and intradermal skin test positive to Dust p Challenges will be performed with placebo or Dp extract three times daily each for 2 weeks. Primary endpoint after nasal challenge with Dust p Mean Symptom score increase by greater than or equal to 2 from baseline. Secondary Outcomes Mean decrease in PNIF by greater than 15percent from baseline. Mean increase in nasal lavage PGD2 and ECP by greater than 15percent from baseline levels. Correlation between the orthogonol diameter of the wheal and flare of the intradermal skin test and the degree of symptom worsening during the nasal challenge. These results will provide evidence for the continued use of the intradermal skin test in evaluating allergic rhinitis.

The study aims to examine the effect of probiotics on the clinical symptoms of allergic rhinitis and to elucidate some of the immunological mechanisms involved.

The main purpose of the trial is to prove the therapeutic value of the product and enable an effective and safe dosage schedule to be recommended

To characterize the pharmacokinetics of diphenhydramine in two pediatric populations: children, ages 2 to < 12 years, and adolescents, ages 12 to < 18 years.

This was a crossover study designed to see if patients with seasonal allergy symptoms preferred Clarinex® or Allegra®. Patients were randomized to take 7 days of Clarinex or Allegra treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Allegra, the patient prefers more.
