Filter by:The aim of the study is to use the antioxidant and antiinflammatory effects of lipoic acid to improve the quality of life of patients with asthma. The investigators will administrate 600 mg lipoic acid orally on a daily basis during two months concurrent with the patient anti-asthmatic therapy and evaluate the effects on resulting pulmonary function, inflammatory and oxidative stress biomarkers and health-related quality of life previous to the initial of the treatment and at 60 days of the supplementary therapy.
The primary objective is to assess the effect of azelastine hydrochloride (AZE) on the relative bioavailability (AUC0-∞) of fluticasone propionate (FLU) when administered as fixed AZE-FLU combination product (TEST) compared to a similar formulation without containing AZE (i.e. FLU alone in the MP29-02 vehicle; REF). The secondary objectives are to compare the relative bioavailability (AUC0-∞) of FLU when administered either as fixed AZE-FLU combination product (TEST) or as marketed FLU product, Fluticasone Propionate Nasal Spray, Roxane Laboratories (COMP); To compare the effects of AZE on other pharmacokinetic parameters of FLU (AUC0 tlast, CL/f, Cmax, tmax, t½); To assess adverse events.

The primary purpose of this study is to investigate effect, tolerability and safety of different dosing regimens of AZD8848 administered intranasally to seasonal allergic rhinitis patients out of season in an allergen challenge model.
Subjects who have a clinical history of perennial rhinitis symptoms associated with dust exposure or not associated with other perennial allergens, will have a positive challenge with Dermatophagoides pteronyssinus. Subjects will be ppt negative and intradermal skin test positive to Dust p Challenges will be performed with placebo or Dp extract three times daily each for 2 weeks. Primary endpoint after nasal challenge with Dust p Mean Symptom score increase by greater than or equal to 2 from baseline. Secondary Outcomes Mean decrease in PNIF by greater than 15percent from baseline. Mean increase in nasal lavage PGD2 and ECP by greater than 15percent from baseline levels. Correlation between the orthogonol diameter of the wheal and flare of the intradermal skin test and the degree of symptom worsening during the nasal challenge. These results will provide evidence for the continued use of the intradermal skin test in evaluating allergic rhinitis.
This is a Phase Ib, randomized, blinded, placebo-controlled, multiple-ascending dose study in patients with seasonal or perennial allergic rhinitis to investigate the safety, tolerability, and pharmacokinetics (PK) of MEMP1972A.
Various studies in animals and humans have shown a potential beneficial effect of probiotics consumption on allergy. However, few studies exist that document their efficacy for upper airways allergies such as allergic rhinitis. The objective of this study is to investigate the effect of short-term oral administration of a Lactobacillus paracasei on a nasal provocation test (NPT) with grass pollen, performed out of pollen season. Adult volunteers with allergic rhinitis are enrolled in a randomized, double-blind, placebo-controlled study, based on two 4-weeks cross-over periods of product consumption (probiotic-fermented milk versus placebo), separated by a washout period of 6-8 weeks. Objective and subjective clinical parameters of NPT as well as systemic and nasal immunological parameters are compared between the two treatment periods.
Allergic rhinitis and asthma are common respiratory diseases, which often coexist. The prevalence of allergic rhinitis in subjects with asthma is up to 80%, and the prevalence of asthma is 3-5 times greater in subjects with rhinitis than healthy controls. The mechanisms of the allergen response in both diseases are parallel to each other, with similar mediator and cellular responses to similar allergens. These observations have led to the suggestion that both diseases are different expressions of one airway disease.We wish to evaluate the effect of low dose theophylline in patients with asthma, given its effects as subtherapeutic concentrations and the propensity to develop adverse events at higher doses.
This study evaluates labeling comprehension, ease of use and effectiveness of a new device for nasal and sinus irrigation and/or aspiration. The device is currently cleared for professional use and home use with a prescription. This is a usability study to demonstrate that this device is appropriate for home use.
The investigators are investigating the early and late responses to allergen challenge. The research participants who the investigators will study (from three cohorts) will be part of independently-approved studies involving allergen challenge. Due to the uniqueness of the cohorts for novel genetic study, it is logical that the investigators should initially undertake hypothesis-generating experiments. The investigators will obtain blood samples from the participants, both pre-challenge and post-challenge. The investigators will determine gene expression and protein differences between these samples, and investigate if there are inherited genetic differences between individuals that may predict their specific responses to allergens.
