About

The objective of this study is to compare the efficacy and safety of Fluticasone Furoate Nasal Spray (FFNS), that is FFNS with placebo in Chinese adult and adolescent subjects with Allergic Rhinitis as AR. There are 3 phases, 2 to14 day run in, 2 week treatment, and 3 to 5 day follow up. After run in period, at least 360 subjects with AR ( ages of 12yrs and 65yrs, inclusive) will be randomised to receive FFNS 110ug once daily or placebo for 2 weeks. The primary endpoint is the change from baseline of reflective total nasal symptom score (rTNSS) during treatment period, and the secondary endpoints include mean change from baseline in nasal finding scores by rhinoscopy at completion of study treatment, and severity of overall inference in activities of daily living. Safety measures include AE (Adverse Event) reports, ECGs (Electrocardiograph), physical exams, vital signs, and nasal exam. In addition, reflective total ocular symptom score (rTOSS) will be measured as an explorative endpoint, only in the specific AR (Allergic Rhinitis) patients with severe ocular symptoms.

Full description

This is a multicenter, 2 week, double blind, randomized, placebo controlled trial. 7 investigational sites will be enlisted to randomize at least 360 subjects (outpatients) during 2009 and 2010. Throughout the entire study period, no antiallergy drugs and rhinitis medication, including rescue medication for symptom relief and anti-hyperactivity will be allowed. The run in period will consist of a minimum of 2 days and a maximum of 14 days. During this period, intermittent allergic rhinitis(IAR) or persistent allergic rhinitis(PER) should be diagnosed confirmatively as the definition from the current ARIA (Allergic Rhinitis and its Impact on Asthma) guideline and the coming effective Chinese allergic rhinitis management guideline. Subjects will assess their nasal symptom scores and compliance in dairy cards to confirm whether to meet randomization criteria. During the treatment period, subjects are randomized (1 and 1 ratio) to FFNS 110ug or matching vehicle placebo nasal spray to self administer intranasal treatment once daily for 2 weeks. Subjects will rate their nasal symptom scores and also document their study drug administration and compliance, any medication conditions experienced, and any concomitant medications taken in their dairy cards. Subjects also assess the severity of overall interference in activities of diary living(ADL) at baseline and the end of study treatment in their questionnaire. At baseline and the end of study treatment, investigators rate nasal findings scores by rhinoscopy, and record them in patient notes. A follow up telephone contact will be made 3 to 5 days after completion of study treatment/early withdrawal to assess for any post treatment adverse effects. The primary endpoint is the change from baseline of reflective total nasal symptom score(rTNSS) during treatment period, and the secondary endpoints include at completion of study treatment, mean change from baseline in nasal finding scores by rhinoscopy, and the severity of overall inference in activities of daily living. The safety measures include ECGs, vital exams, physical exams, and AE reports. In addition, reflective total ocular symptom score(rTOSS) will be measured as an explorative endpoint, only in the specific AR patients with severe ocular symptoms.
