Active clinical trials for "Rhinitis, Allergic, Seasonal"

This study is to evaluate the equivalence of generic ciclesonide nasal spray with that of the marketed drug, Omnaris™ nasal spray, in the treatment of seasonal allergic rhinitis, and to evaluate the safety and tolerability of generic ciclesonide nasal spray compared with Omnaris™ nasal spray.

This study will investigate the safety and efficacy of olopatadine hydrochloride / ketorolac tromethamine fixed dose combination ophthalmic solution compared with olopatadine hydrochloride ophthalmic solution in patients with seasonal allergic conjunctivitis.

The purpose of this study is to determine the safety and tolerability of several doses of ragweed pollen allergen extract administered as sublingual tablets in subjects with allergic rhinitis to ragweed.

This is an efficacy study of bepotastine besilate nasal spray in seasonal allergic rhinitis.

More than 70% of birch pollen allergic patients suffer from allergic reactions to certain foods, e.g. stone fruits, hazelnut and some vegetables. However, specific immunotherapy (SIT) with birch pollen extract is not effective for the treatment of associated food allergy in a substantial number of patients. Based on our previous clinical and immunological investigations of birch pollen related food allergy (BPRFA) the investigators hypothesize that for effective SIT of this abundant food allergy the disease-eliciting food allergens should be employed. To prove this concept, the investigators aim to sublingually administer the major apple allergen, Mal d 1, to birch pollen-allergic patients with concomitant apple allergy and evaluate clinical and immunological effects of this treatment. The investigators choose Mal d 1 as model food allergen because (i) its cross-reactivity with Bet v 1 has been well characterized,(ii) apple is the most frequent trigger for BPRFA and (iii) recombinant(r)Mal d 1 was well tolerated after sublingual administration to 20 birch pollen-allergic patients in a previous study. Sublingual administration of a defined concentration of GMP-rMal d 1 will be compared with equal doses of GMP-rBet v 1 as a positive control and placebo-treatment. Clinical parameters will include skin prick tests (SPT) and objective and subjective assessment of apple and birch pollen-induced allergic symptoms. Immunological parameters will comprise the analysis of antibody and T cell responses to Mal d 1 and Bet v 1 as well as the evaluation of basophil activation. The proposed pilot study will be a first investigation of the concept to specifically treat BPRFA with the involved food allergens and thus, represents an important step in the development of an efficient and safe therapy in the future.

This study will compare the nasal congestion symptom relief of phenylephrine extended release tablets and placebo in participants with allergic rhinitis.

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

To report and compare total symptom scores, nasal symptom scores, post-nasal drip symptom scores, and adverse reactions in and between SAR subjects on active drug and SAR subjects on placebo.

The objective of the current study is to investigate the efficacy, safety and tolerability of BI 671800 ED using three dose levels of BI 671800 ED (50 mg, 200 mg and 400 mg), administered twice daily compared to FP (fluticasone propionate) nasal 100 mcg per nostril qd in the morning or Montelukast 10 mg qd am given for 2 weeks in patients with SAR (seasonal allergic rhinitis) out of season using an environmental exposure chamber in patients known to be sensitive to the aero-allergen Dactylis glomerata.

The primary objective of this study is to demonstrate the efficacy of ciclesonide HFA, applied as a nasal aerosol once daily, in patients with SAR. The secondary objectives are to evaluate Quality-of-Life and safety.
