Filter by:This study will assess the efficacy and safety of different doses of ACT-129968 in adult patients with seasonal allergic rhinitis, due to mountain cedar pollen.
The airways of the lung are lined by specialised cells called airway epithelial cells. As well as being at the interface between the lungs and the air we breathe; airway epithelial cell (AEC) function is altered in people with respiratory diseases such as asthma. AEC secrete many mediators that contribute to asthma symptoms and these also contribute to asthmatic inflammation in the lungs. The study of such cells is difficult because of their location deep in the lungs. Nasal airway epithelial cells provide a useful and easily accessible model of model of lower airway cells. This study will examine whether the asthma medication Singulair (montelukast) can inhibit the inflammatory secretions of nasal AEC of asthmatic patents who also have allergic rhinitis compared with patients who have asthma alone. We will also examine if montelukast has differential modulating effects in these two patient groups.
The purpose of this study is to examine the safety and efficacy of bepotastine besilate nasal product in seasonal allergic rhinitis patients.
Previous publications have indicated that Allergic Rhinitis (AR) patients suffering from both ocular and nasal symptoms have a greater burden of illness and lower quality of life than patients suffering from nasal symptoms alone. Fluticasone furoate (FF) acts against both nasal and ocular symptoms. The purpose of this study was to evaluate the differences in symptom control (both perceptually and objectively) and resource use for patients with current seasonal AR.
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.

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.
To report and compare total symptom scores, nasal symptom scores, post-nasal drip symptom scores, and adverse reactions in and between SAR subjects on active drug and SAR subjects on placebo.
Mometasone furoate nasal spray (MFNS) is a once-a-day product. This is a multi-center, open-label study of MFNS in children with perennial allergic rhinitis. MFNS will be administered to pediatric subjects (3-15 years old) with perennial allergic rhinitis at a dose of 100 to 200 μg/day (once daily) for 12 weeks. Subjects (subject's legal representatives) provided consent to continue treatment beyond 12 weeks will receive treatment for up to 24 weeks. At each clinic visit, observation of adverse events, nasal symptom scores, and nasal findings will be evaluated. The presence/absence of serious adverse events and trial procedure-related AEs will be reviewed 30 days after the end of the follow-up.
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.
