Active clinical trials for "Rhinitis, Allergic, Seasonal"

The purpose of the study is to assess the efficacy and safety of an investigational nasal aerosol compared with placebo nasal aerosol in the treatment of seasonal allergic rhinitis.

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.

The purpose of this study is to determine the efficacy and safety of three doses of r Bet v1 administered as sublingual tablets in birch pollen allergic subjects.

A randomized, double-blind, placebo-controlled parallel-group study, comparing the bioequivalence of triamcinolone acetonide aqueous nasal spray (Apotex, Inc.) to that of Nasacort® AQ nasal spray (Sanofi-Aventis Pharmaceutical Products, Inc.) in the treatment of seasonal allergic rhinitis.

The purpose of this study is to determine if the combination of two allergy medications (formulated azelastine/fluticasone product)is more effective than placebo or either component medication alone (azelastine or fluticasone).

The purpose of this study is to determine the safety and tolerability of several doses of r Bet v1 administered as sub-lingual tablets in subjects sensitised to birch pollen.

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.

The purpose of this study is to compare the efficacy of Olopatadine Nasal Spray with Azelastine Nasal Spray when treatments are utilized in conjunction with Fluticasone Nasal Spray for the treatment of seasonal allergic rhinitis.

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.

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.
