Active clinical trials for "Rhinitis, Allergic"

Clinical Trial to Evaluate the Efficacy and Safety of CKD-342

To evaluate the long term safety and efficacy of GSP 301 NS compared to 2 placebo NS formulations for the treatment of perennial allergic rhinitis (subjects 12 years of age and older)

The purpose of this 2-year study is to assess the sustained clinical efficacy and safety of 300 IR/day of a sublingual solution of birch pollen allergen extract starting 4 months prior to the birch pollen season and continuing over the birch pollen season compared with placebo for reduction of rhinoconjunctivitis-related symptoms and anti-allergy medication usage.

The purpose of this study is to evaluate the efficacy of a probiotic strain in improving the quality of life in adult subjects suffering from perennial allergic rhinit.

This is a study to evaluate the efficacy and safety of grass sublingual tablet (SCH 697243) versus placebo in the treatment of grass pollen-induced allergic hayfever symptoms. Participants will receive either the sublingual grass tablet or a placebo tablet during the study. It is expected that those participants receiving the active sublingual grass tablet will have less hayfever symptoms and need less medications to treat hayfever symptoms during the grass pollen season.

This is a multicenter, randomized, double-blind, placebo-controlled, parallel group, safety study of the effects of ciclesonide nasal aerosol (74 mcg) on the HPA axis when administered once daily to male and premenarchal female subjects 6 to 11 years of age with a diagnosis of PAR.

The purpose of this research study is to investigate whether sublingual immunotherapy (SLIT, grass pollen tablets under the tongue) has long term effects in severe hay fever.

The purpose of this study was to evaluate the effects of Ischia thermal waters nasal irrigation on allergic rhinitis and airway inflammation during the period of natural exposure to parietaria pollen in children with allergic rhinitis and intermittent asthma.

Ectoin acts on membranes by forming an Ectoin-Hydro-Complex therewith providing a protection against external agents like aeroallergens. The effects of Ectoin containing nasal spray and eye drops have already been demonstrated in several studies with adult Seasonal Allergic Rhinitis (SAR) patients and it was shown that they can effectively reduce symptoms of allergic rhinitis without resulting in any significant adverse events. The aim of this clinical investigation is to demonstrate the safety, tolerability and efficacy of Ectoin Nasal Spray and Ectoin Eye Drops in pediatric and adolescent SAR patients. It is assumed that Ectoin containing products show an excellent safety profile and very good tolerability together with a potent efficacy in the treatment of SAR.

Allergic diseases represent a major health issue worldwide and epidemiological studies in Melbourne, Australia, have reported a high prevalence of rhinitis (hayfever) and atopy (genetic tendency to make allergy antibody) in Asian and Caucasian subjects. Mainstay treatment of allergic rhinitis is allergen avoidance and pharmacotherapy for symptom relief. Allergen immunotherapy offers the advantages of specific treatment with long lasting efficacy, and can modify the course of disease. However, use of this treatment is restricted by the high risk of adverse events especially in asthmatics. Other, better tolerated, routes of allergen administration than the current conventional subcutaneous route (SCIT) have been investigated including the sublingual route (SLIT) and recently sublingual tablets for pollen allergy immunotherapy became available. The tablets are safe and easy to use and contain pollen extracts from 5 of the most common allergy-causing European grasses but include ryegrass (Lolium perenne), the major seasonal pollen for allergy in Melbourne and south-eastern Australia. The immunological mechanisms of sublingual immunotherapy are not fully understood. The investigators propose conducting a longitudinal open label study to investigate the immunological changes that occur with the 5 grass pollen sublingual immunotherapy tablet (Oralair®) in a cohort of Chinese and non-Chinese background subjects. The investigators will investigate the induction of relevant T cell regulatory immune mechanisms and changes in serum allergen-specific immunoglobulin (Ig) E and IgG4. Immunoregulatory cytokine synthesis and T cell phenotype (Bio-plex and flow cytometry) will be examined. This project will provide important fundamental knowledge on which to inform decisions for the greater application of this treatment for subjects with moderate and severe allergic rhinitis.
