Filter by:ASIT naïve patients sensitized to grass pollens will be recruited for the study. All of them will be instructed to treat bothersome in-season symptoms when they appear (on as needed, pro re nata basis) with rescue medication. They will be given 5 different options and will be informed about the effects of each of them in order to make their optimal choice for different symptoms and their combination: local decongestant (xylomethazoline, when congestion is leading), local antihistamine (azelastine, when itching, sneezing and rhinorhea a predominant), nasal corticosteroid (momethasone, when all nasal symptoms are pressing and no adequate relief is obtained form the other 2 local treatments), oral antihistamine (bilastine, when itching and sneezing persist despite the local treatments) and oral corticosteroid (prednisolone, when any or all symptoms become unbearable despite the other suggested treatments). Patients who are reluctant to use immunotherapy or who are too late to initiate it will be randomized to be treated with the listed medications on as needed basis, the nasally applied formulations will be followed by either HPMC to prolong and enhance their effect (Group HPMC) or placebo (lactose powder) (Group Placebo) to serve as control. Patients indicated and willing to carry out ASIT will be treated according to the standard protocol with grass allergens sublingually (Staloral #688) and will receive rescue medication (Group Immunotherapy).
The purpose of this study is to assess the efficacy and safety of short ragweed pollen allergen extract (MK-3641, SCH 039641, RAGWITEK™) sublingual immunotherapy tablets in children aged 5 to 17 years with ragweed-induced allergic rhinitis/rhinoconjunctivitis with or without asthma. The primary hypothesis of this study is that administration of short ragweed pollen allergen extract sublingual immunotherapy tablets to children 5 to 17 years of age, compared with placebo, will result in a significant reduction in the combination of rhinoconjunctivitis symptoms and medication use over the peak ragweed season (RS).
Examine safety and immunological response for ASP4070 when vaccinated in patients with pollen allergy
Dymista, a combined product containing the antihistamine azelastine and the intranasal steroid fluticasone, provides superior clinical efficacy to both fluticasone propionate and azelastine hydrochloride in the treatment of seasonal allergic rhinitis. The superiority of efficacy not only occurs at the initiation of treatment, but persists for its duration. The mechanism underlying the superior efficacy of Dymista is not known. This trial focuses on examining the effects of Dymista on the dynamics of the allergic response in man using nasal provocation with antigen. The investigators will study the relationship between symptoms, physiology, cells and mediators.
Single-center, double-masked, randomized, placebo-controlled, parallel-group, efficacy and safety study using the Allergen BioCube (ABC).
In this randomized, double-blind, placebo-controlled study, participants with seasonal allergies will receive a daily probiotic or placebo for 8 weeks. Questionnaires will assess health-related quality of life, stress, physical activity, gastrointestinal symptoms, adverse events, and compliance. In a subset of subjects, stool and blood samples will be collected at baseline and at week 6 of the intervention (estimated to be peak allergy season) to characterize microbial communities and immune function.
This is an efficacy and safety study of desloratadine (MK-4117) in Japanese participants with seasonal allergic rhinitis (SAR). The primary hypothesis of this study is that the change from Baseline in Total Nasal Symptom Score (TNSS) is improved by desloratadine compared to placebo.
Study to evaluate the two different strengths and dose regimen of GSP 301 to be effective in treatment of seasonal allergic rhinitis.
This study is to evaluate the equivalence of generic Azelastine Hydrochloride and Fluticasone Propionate Nasal Spray with that of the marketed drug, Dymista™ Nasal Spray, in the treatment of seasonal allergic rhinitis, and to evaluate the safety and tolerability of generic Azelastine Hydrochloride and Fluticasone Propionate nasal spray compared with Dymista™ nasal spray.
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.
