Active clinical trials for "Rhinitis, Allergic, Seasonal"

Evaluation of the effect of fluticasone propionate vs placebo applied as nasal spray on the increase of allergen-specific serum IgE levels following nasal exposure to recombinant allergens. Nasal sprays will be applied for four weeks starting two weeks before nasal provocation and serum IgE levels will be followed during eight weeks after nasal provocation.

The aim of the study is to identify changes in potential biomarkers after peptide immunotherapy for that may subsequently be developed as biomarkers that correlate with clinical efficacy.

Comparative study on clinical efficacy and safety of levocetirizine and desloratadine as measured by the subject's satisfaction/dissatisfaction after one week of treatment

This is a randomised, double-blind, placebo-controlled, international, multicentre, confirmatory Phase III study in patients with grass pollen-related allergic rhinoconjunctivitis. After having given written informed consent, the patients will be examined to establish eligibility according to inclusion/exclusion criteria. The eligible patients will be randomised to Placebo or gpASIT+™ treatment according to a 1:1 ratio. Study treatment will be administered before the start of the pollen season in 2019

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.

The purpose of this study is to determine at which point in the dosing regime grass pollen immunotherapy causes a significant reduction in the late skin response to allergen challenge. A once weekly cluster regimen of 2 injections per visit was employed during the up-dosing phase, followed by monthly maintenance injections of 100,000 SQ units. Symptom scores and need of rescue medication were recorded by patients during the study period. The size of early and late cutaneous response to allergen challenge was recorded and measured by a physician.

The purpose of this study is to determine whether exhaled breath temperature, a surrogate marker of airway inflammation, rises during the pollen season in sensitized subjects with allergic rhinoconjucnctivitis with or without mild asthma. Sublingual Immunotherapy with respective allergens suppresses the seasonal increase of EBT. During the second year (2013) of the trial all patients will be treated with 5 grass allergen extract: carry over differences between the active and placebo arms from the previous year (2012) will be looked for.

Nasal irrigation (NI) is recommended as an add-on therapy in patients with allergic rhinitis (AR). The primary purpose of this study was to evaluate the clinical effectiveness of adding hyaluronic acid (HA) solution and normal saline (NSS) to nasal steroid (NS) therapy as add - on therapy in improving quality of life and reducing nasal symptom scores of children with seasonal AR (SAR) with regards to NS therapy. Our secondary purpose was to demonstrate the effects on eosinophil count in nasal cytology (NEC), nasal airflow (NAF), and resistance (NAR).

This study is a prospective observational cohort study with 3-month follow-up among a cohort of intranasal steroid (INS) -experienced patients newly starting fluticasone furorate nasal spray (FFNS). The primary aim is to examine the effect of FFNS on the use and associated cost of concomitant allergic rhinitis medications in INS-experienced patients starting treatment with FFNS who have a history of prior concomitant medication use. The secondary aim will be to determine the effect of FFNS on control of allergic rhinitis, as assessed by the Rhinitis Control Assessment Test (RCAT). Adult patients filling a new FFNS prescription will be recruited (within 4 days of starting their FFNS) across 50 branches of a retail pharmacy chain with co-located convenient care clinics. Approximately 350 patients who have active seasonal rhinitis and have used an INS other than FFNS and another prescription or over-the-counter allergy medication in the previous allergy season will be eligible for the study. A baseline questionnaire will be administered to collect information on patient demographics, a brief medical history of the patient's rhinitis, prior use of INS and other prescription and over-the-counter medications taken for allergic rhinitis, total out of pocket costs for the prior allergy season, number of office visits due to allergic rhinitis, and level of control of symptoms of allergic rhinitis. At 1, 2, and 3 months post-enrollment, a follow-up questionnaire will be administered to collect information on medications taken for allergic rhinitis, office visits due to rhinitis, and level of control of symptoms of allergic rhinitis. In addition, pharmacy claims data will be abstracted for patients 1 year prior to enrollment and 4 months after enrollment to verify and supplement patient reported data as needed. The primary outcomes will be rate of use of non-INS concomitant medications (frequency and duration) at baseline, and 1, 2, and 3 months follow-up and change in rate of use of non-INS concomitant medications (post vs. pre and from baseline to 3 months follow-up). Secondary outcomes will be change in total allergic rhinitis pharmacy expenditures (post vs. pre and from baseline to follow-up) and change in the level of control of allergic rhinitis, as measured by score on the Rhinitis Control Assessment Test (RCAT), from baseline to follow-up.

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).
