a phase-iv, open-label study to evaluate safety/tolerability of once-daily avamys (tm) aqueous nasal spray 110mcg among vietnamese adult patients with established perennial allergic rhinitis

Conditions: Rhinitis, Allergic, Perennial

Summary: allergic rhinitis is an ige-mediated, inflammatory disorder of the upper airway that occurs following allergen exposure. perennial allergic rhinitis (par) starts in early childhood and occurs all year around. it's caused by allergy to the aerosolised droppings of house dust mites and pet skin flakes (dander). occasionally, indoor mould spores and, in rare cases, food allergy can be causes. intranasal corticosteroids are highly effective medications for controlling the nasal symptoms that accompany allergic rhinitis. avamys (tm) (fluticasone furoate aqueous nasal spray 100mcg) has been shown having effects on nasal symptoms of seasonal and perennial allergic rhinitis and on the ocular symptoms of allergic rhinitis and has been evaluated as effective and safe for treatment seasonal and perennial allergic rhinitis by fda. it is speculated that avamys (tm) is also effective and safe for vietnamese patients. however before being used widely for patients across the country, avamys (tm) should be proved that it is safe for vietnamese patients. the objective of this study is to evaluate the safety of fluticasone furoate aqueous nasal spray 110mcg once daily in adults with par. this is a 6-week, open trial. a study center will be enlisted to recruit a minimum of 50 par subjects. at the visit 1, subjects who fulfill the inclusion criteria are eligible to be included in the group to self-administer intranasal treatment of fluticasone furoate aqueous nasal spray 110 mcg once daily for 6 week. the subjects are instructed to administer two sprays from the device into each nostril once daily every morning. administration of the dose will be performed by alternately spraying one spray to each nostril followed by a second spray to each nostril. subjects will not be permitted to take any anti-allergy or rhinitis medication during the screening or treatment period. throughout the study, subjects will document their study drug administration/compliance, any medical conditions experienced, and any concomitant medications taken. all subjects are outpatients. the safety assessments include a summary of the frequency and type of clinical adverse events that occur during the study. in addition, hematology and chemistry analyses of blood samples are also implemented. a physical examination and nasal examination are also performed and vital signs collected. twelve-lead ecgs are performed at all visits.
