Active clinical trials for "Rhinitis, Allergic, Seasonal"

The purpose of this study is to assess the effect of reducing exposure to allergens in patients with hay fever by means of a nasal filter.

This study will assess the efficacy and safety of different doses of ACT-129968 in adult patients with seasonal allergic rhinitis, due to mountain cedar pollen.

The study will evaluate the efficacy and safety of BM32 in grass pollen allergic subjects. It will test the hypothesis that either of two doses of BM32 will lead to a sustained relief off allergy symptoms over a two year study period.

The aim of the study is to compare the safety, clinical tolerability, immunogenicity and efficacy of gpASIT+TM (grass pollen peptides) alone and combined with an immunoregulating adjuvant, in a short course administration (5 injections over 4 weeks).

The dose and the mode of administration of sublingual therapy remain open questions to determine the efficacy and safety of this desensitization therapy, the main purpose of this study is to evaluate if different routes of administration (oral-vestibular vs. sublingual) and a maximum dose of allergen administered are able to determine a different effect or a different incidence of side effects of the therapy in a group of patients with rhinoconjunctivitis and/or asthma due to ragweed

The purpose of this study was to test the effectiveness and side effects of desloratadine (Aerius) in patients with hayfever. Patients took desloratadine once a day for 15 days. At the end of therapy, they scored how severe their hayfever symptoms were and how they responded to therapy. Side effects were recorded.

This study will compare the effectiveness of QAV680 against placebo in treating the symptoms of seasonal allergic rhinitis in an Environmental Exposure Chamber.

Primary Objective: - To evaluate the efficacy on the nasal congestion of a twice-daily fexofenadine HCl 60 mg - pseudoephedrine HCl 60 mg combination (FEX60/PSE60) and fexofenadine HCl 60 mg - pseudoephedrine HCl 120 mg combination (FEX60/PSE120) versus fexofenadine HCl 60 mg (FEX60) in patients with seasonal allergic rhinitis (SAR). Secondary Objectives: To evaluate the efficacy of a twice-daily FEX60/PSE60 and FEX60/PSE120 versus FEX60 on nasal symptoms (sneezing, rhinorrhea, and nasal congestion), eye symptom, and daily activity impairment. To assess the safety of a twice-daily FEX60/PSE60 and FEX60/PSE120 versus FEX60.

This is a study to evaluate the treatment effect of montelukast 10 mg taken in the morning, versus placebo, in patients with seasonal allergic rhinitis. Loratadine is included in the study as an active control.

The primary objective of this placebo-controlled EEC study is to determine the time to onset of action of ciclesonide, applied as a nasal spray (200 mg, once daily) in patients with SAR.
