There is a regulatory requirement to evaluate the extent of reduction (if any) of growth velocity associated with inhaled corticosteroid (ICS) containing products that are to be administered to children, and to this end there is Food and Drug Administration (FDA) regulatory guidance. This is a randomised, single-blind (run-in period)/double-blind (treatment period), parallel group, placebo controlled, multicentre study to assess the effect of once daily (OD) inhaled fluticasone furoate (FF) 50 microgram (mcg) on growth velocity in prepubertal asthmatic children on a background therapy of open-label montelukast. This study will be conducted over a total duration of approximately 76 weeks: 16-week run-in period (single-blind placebo inhaler), 52-week double-blind treatment period (inhaled FF 50 mcg /placebo administered OD in the morning for 52 weeks) and 8-week follow-up period. The purpose of the study is to evaluate the magnitude of effect (with a level of precision) on growth velocity of prepubertal asthmatic paediatric subjects (aged 5 to <9 years) following administration of OD inhaled FF 50 mcg for one year. This study fulfills European Union (EU) and United States (US) regulatory requirements for the evaluation of potential growth suppression in children.

---|---|---|---|---|
Primary | Growth Velocity (Centimeter Per Year) Over the Double-blind Treatment Period, as Determined by Stadiometry | Three reproducible height measurements were taken using a stadiometer at each visit and were recorded to nearest 1/10th of centimeter. Each set of triplicate measurements was averaged to derive one estimated height per participant per visit. Growth velocity was calculated for each participant over double-blind treatment period (up to 52 weeks [wk]) by fitting a regression line to averaged height measurements at each visit for that participant during period. Slope of this regression line was participant's growth velocity for double-blind treatment period. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline was included as covariate which was calculated based on stadiometric height measurements recorded at Visits 1(wk -16), 3(wk-8), and 5(wk0), data from at least two of these visits were used to fit a simple linear regression line against time and the slope of the fitted regression line was the participant's Baseline growth velocity. | Up to 52 weeks | |
Secondary | Percentage of Participants Below the Third Percentile of Growth Velocity During Double-blind Treatment Period | Three reproducible height measurements were taken using stadiometer at each visit&were recorded to nearest 1/10th of a centimeter.Each set of triplicate measurements was averaged to derive one estimated height per participant per visit.Growth velocity(GV)was calculated for each participant over double-blind treatment(up to 52 weeks)period by fitting regression line to height measurements recorded for that participant during period.Each participant's double-blind(DB) treatment period GV was calculated based on all on &off treatment height data &was programmatically compared to data values from Standards from Birth to Maturity for Height,Weight,Height Velocity, established in British Children(1965)&further updated for North American children(1985)using 3rd percentile value of age closest to participant's age at end of endpoint(i.e.either end of participant's DB treatment period [Visit18 Wk 52]/withdrawal from study[Early Withdrawal Visit]).Percentage values presented is rounded off. | Up to 52 weeks | |
Secondary | Percentage of Participants With Change in Growth Velocity Quartiles From Baseline to Endpoint | Growth velocity(GV) quartile(defined as 1st quartile(1Q)=1st-25th percentile,2Q=26th-50th percentile,3Q=51st-75th percentile,4Q=76th-100th percentile) was determined at Baseline&endpoint.Endpoint was defined as slope of simple linear regression of average stadiometric height recorded at week 28& upto wk52.Baseline growth velocity was calculated as slope from simple linear regression of average stadiometric height recorded at wk-16,-8&0.Baseline GV was programmatically compared to reference for standard height data using participant's estimated age at wk0& age in reference data closest to actual age of participant to determine Baseline GV quartile.Endpoint GV was programmatically compared to reference data using participant's age at endpoint & age in reference data that was closest to actual age of participant to determine endpoint GV quartile. Any increase/decrease indicates any increase/decrease in quartiles with reference to Baseline. Percentage values presented is rounded off. | Baseline and Endpoint (Week 28[Visit 12] up to and including Week 52 [Visit 18]) | |
Secondary | Growth Velocity Over the First 12 Weeks of Double-blind Treatment Period | Growth velocity was calculated for each participant over double blind period by fitting regression line to height measurements recorded for that participant during period.Slope of this regression line was participant's growth velocity for double-blind treatment period.In order to be included in this analysis,participant must have data from Visit8(Wk 12) stadiometric height assessment.Baseline was included as covariate which was calculated based on stadiometric height measurements recorded at Visits 1(wk -16),3(wk-8),& 5(wk0),data from at least two of these visits were used to fit simple linear regression line against time&slope of fitted regression line was participant's Baseline growth velocity.All available height data collected during double-blind treatment period upto Visit8(Wk12) while participant was on randomized double-blind treatment was considered.ANCOVA model was used to estimate mean treatment difference in growth velocity over 1st 12weeks of double-blind treatment period. | Up to 12 weeks (Visit 8) of double-blind treatment period | |
Secondary | Change in Height Standard Deviation Scores (SDS) From Baseline to Endpoint | Each participant's SDS for each of three required stadiometric height measurements was calculated as:(observed height measurement-standard median height for age at Visit [week-16]) divided by (/) ([standard 95th height percentile for age at visit-standard 5th height percentile for age at visit]/[2*1.645]).Standard median, 95th percentile, & 5th percentile values were obtained from standard tables (Guidance for Industry Orally Inhaled & Intranasal Corticosteroid). SDS for each height stadiometric measurement at each visit was calculated using percentiles from standard tables & averaged for each participant before being summarized by treatment group. A reduction in SDS over time indicates growth deceleration & an increase in SDS over time means growth acceleration.Baseline was defined as height SD score at Visit 5 (week 0). Endpoint was defined as height SD score at Visit 18 (week52) (on- & off-treatment data). Change from Baseline was calculated as Endpoint value minus Baseline value. | Baseline (Week 0 [Visit 5]) and up to Endpoint (Week 52 [Visit 18]) | |
Secondary | Number of Participants With Non-serious Adverse Events (AEs) and Serious Adverse Events (SAEs) | An AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A SAE is defined as any untoward medical occurrence that, at any dose which results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other situations as per investigator's judgement. | Up to 76 weeks | |
Secondary | Number of Participants With On-treatment Asthma Exacerbations Over Double-blind Treatment Period | An exacerbation is defined as deterioration of asthma requiring the use of systemic corticosteroids (tablets, suspension, or injection) for at least 3 days or a single depot corticosteroid injection, or an in-patient hospitalization or emergency department (ED) visit due to asthma that required systemic corticosteroids. Number of participants with on-treatment asthma exacerbations during double-blind treatment period is presented. | Up to 52 weeks |
