Active clinical trials for "Rhinitis, Allergic, Seasonal"

The objective of this study is to investigate the safety, tolerability, and pharmacokinetics of MT-2990 in patients with Japanese cedar pollen-induced seasonal allergic rhinitis (JC-SAR). Additional objective of the study is to investigate the efficacy and pharmacodynamics profile of MT-2990 in an environmental exposure chamber (EEC) on Day 8, 29, 57, and 85.

There is increasing evidence that the effectiveness of allergy immunotherapy to control symptoms of rhinoconjunctivitis is related to the cumulative dose of allergen or allergoid administered during a single regimen of subcutaneous (SC) injections or of sublingual administration. Previously, high cumulative doses of the Grass MATA MPL 10200 and 18200 SU (Standardized Units) were compared with the marketed dose of 5100 SU and were found to have acceptable tolerability and safety. The purpose of this study is to evaluate the tolerability and safety of an even higher cumulative dose regimen of 35600 SU. of Grass MATA MPL compared with placebo in patients with seasonal allergic rhinoconjunctivitis (SAR) due to grass pollen, to enable selection of the best dose to take forward for further development.

Several studies have reported a deficit and/or a defect in regulatory T cells in allergic subjects, which can be correlated with the allergic responses, especially for respiratory allergies. Low-dose IL-2 (ld-IL2) specifically targets and activates regulatory T cells (Tregs), which are cells that regulate immune responses. Thus by stimulating Tregs, ld-IL2 would control allergic responses. This study is designed to evaluate the efficacy of ILT-101 (ld-IL-2), compared to placebo, on the nasal response assessed by Total Nasal Symptom Score (TNSS) during a controlled birch allergen exposure.

A single-center, double-blind, placebo-controlled study of FDC olopatadine hydrochloride and mometasone furoate nasal spray (Molo; also referred as GSP 301) was conducted in subjects with seasonal allergic rhinitis. In this study, the efficacy and safety of two regimens (BID and QD) of the FDC (i.e. Molo 1 and Molo 2) were evaluated compared to placebo nasal spray, DYMISTA® and PATANASE®.

PQGrass309 is aimed at exploring the expected average treatment effect of PQ Grass 27600 SU cumulative dose on symptom and medication score in a field setting. The study will enrol adult subjects with seasonal allergic rhinitis and/or rhinoconjunctivitis (SAR) induced by grass pollen exposure.

This study is to assess the onset of action of fixed drug combination of azelastine hydrochloride and fluticasone propionate nasal spray (Dymista) in treating the nasal symptoms of seasonal allergic rhinitis (SAR) induced by an allergen challenge in an Environmental Exposure Unit (EEU).

The primary objective of the study was to examine the efficacy and safety of S-555739/cetirizine HCl compared with the individual components and placebo.

The purpose of this study is to explore the efficacy and safety of Ciclesonide Nasal Spray 200 microgram (mcg) once daily in the treatment of seasonal allergic rhinitis (SAR) in Russian participants.

The purpose of this study is to assess the safety and efficacy of an investigational nasal aerosol at two doses compared with placebo nasal aerosol in the treatment of seasonal allergic rhinitis in children (6-11 years of age).

RV568 is being developed for the treatment of diseases such as asthma, COPD and allergic rhinitis (e.g. hayfever). The main aim of this study is to investigate whether RV568 ameliorates the nasal symptoms to low doses of grass pollen in healthy subjects with seasonal allergic rhinitis.
