Safety Study To Assess Growth In Children With Seasonal Allergic And/Or Perennial Allergic Rhinitis Treated With GW685698X Aqueous Nasal Spray Or Placebo Nasal Spray
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to assess any effect in children with seasonal and/or perennial allergic rhinitis by GW685698X aqueous nasal spray (versus vehicle placebo nasal spray) on growth using knemometry.
A Randomised, Double-Blind, Placebo-Controlled, Two-Week Crossover, Knemometric Assessment of the Effect of Fluticasone Furoate Nasal Spray 100mcg Once Daily on Short-Term Growth in Children Aged 6 to 11 Years With Seasonal and/or Perennial Allergic Rhinitis
The primary safety endpoint will be the mean growth velocity (mm/wk) in lower leg growth, as determined by knemometry, over a 2-week treatment period with intranasal GW685698X aqueous nasal spray versus a 2-week treatment with placebo nasal spray.
Secondary Outcome Measures :
Secondary endpoints will include the frequency and type of clinical adverse events (AEs) experienced during treatment, nasal examinations, vital signs (systolic and diastolic blood pressure, heart rate [pulse]).
