Active clinical trials for "Rhinitis, Allergic"

This was a randomized, double-blind, parallel-group, multicenter study that used both an active control (fexofenadine) and a placebo control to evaluate desloratadine 5 mg once daily during a 15-day treatment period. The active treatments and placebo were allocated in a 2:2:1 ratio.

This was a study to measure the ability of desloratadine and levocetirizine to decrease nasal obstruction in subjects who had study-induced allergic rhinitis. Study participants had allergic rhinitis symptoms induced in a Vienna Challenge Chamber and then received desloratadine or levocetirizine for 8 days. After at least a 10 to 35-day washout period (time when no drug is given), subjects received the opposite treatment for 8 days. Subjects had their total nasal symptom measured.on the 8th day of each treatment period.

This is study of LMC, phenylephrine, and placebo in subjects with SAR. There are three visits: At Visit 1, subjects will be evaluated for participation and, if they qualify, will attend Visit 2 for priming. At Visit 2, ragweed pollen will be fed continuously and dispensed into the environmental exposure unit to induce an allergic reaction. Pollen counts will be monitored and recorded. During the priming visit(s), subjects will be evaluated to determine if they qualify. If qualified, they will return for Visit 3, where ragweed pollen will be fed continuously and dispensed into the environmental exposure unit to induce an allergic reaction. Pollen counts will be monitored and recorded as in the Priming Session. Subjects will complete symptom evaluations and if qualified, they will receive study medication and remain in the environmental exposure unit where symptoms will be evaluated for 8 hours after dosing. PNIF will be evaluated only during the treatment session. Four nasal symptoms (rhinorrhea, nasal congestion, sneezing, and nasal itching) and three non-nasal symptoms (itching/burning eyes, tearing/watery eyes, and itching of ears/palate) will be evaluated. Adverse events will be collected throughout the study to assess safety and tolerability, and vital signs will be collected at Visit 1 and at the end of Visit 3.

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 purpose of this study is to compare the effects (effectiveness and safety) of an intranasal corticosteroid (fluticasone furoate nasal spray [FFNS]), with a placebo nasal spray for the treatment of perennial (year-round) allergic rhinitis.

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.

The purpose of this study is to compare the systemic des-ciclesonide exposure of OMNARIS™ (ciclesonide) nasal spray, ciclesonide HFA nasal aerosol, and orally inhaled ciclesonide HFA-metered-dose inhaler (MDI). The administration of the study medication will be as follows: three single doses, separated by a wash-out period. The study will provide further data on the safety and tolerability of ciclesonide.

Allergic rhinitis(AR) is one of the most common allergic disorders throughout the world.The conventional therapies are effective in alleviating symptoms but the efficacy are limited and not persistent. Furthermonre, the cost and side-effect are known defects. A classical Chinese herbal formula, has been used for AR for centries. Our study purpose is to evaluate the clinical efficacy and safety of this formula verus placebo in perennial allergic rhinitis (PAR). Hypothesis: the classical herbal formula would improve the symptoms of PAR patients and change some immunological parameters in the peripheral blood when comparing with the placebo.
