Recruitment
|
||||||||||||||||
Recruitment details |
Study consisted of run-in period of two-weeks followed by two treatment periods of 14 days each (+/- 4 days) separated by a 14-day washout period and a follow-up visit of approximately 7 days post last dose. The total participation time in the study was approximately 9 Weeks. | |||||||||||||||
Pre-assignment

||||||||||||||||
Screening details |
A total of 60 participants were randomized to receive one of the two treatment sequences; placebo followed by inhaled fluticasone furoate or inhaled fluticasone furoate followed by placebo. All 60 participants received at least one single dose of study medication. | |||||||||||||||

Participants received oral inhalation of 50 microgram (mcg) fluticasone furoate (FF) once daily (OD) or placebo for 14 days in either of the treatment periods in a two-way crossover design. Sequence 1 participants received oral inhalation of placebo OD for 14 days +/- 4 days in Treatment Period 1, followed by oral inhalation of FF 50 mcg, OD for 14 days +/- 4 days in Treatment Period 2. The two treatment periods were separated by a two-week wash-out period. Additionally, all participants were provided a salbutamol inhaler for symptomatic relief of asthma symptoms during the 2-week run-in, washout, and treatment periods as needed. | |||||||||||||||

End point title |
Mean growth rate in lower-leg growth (mm/week), as determined by knemometry | ||||||||||||
End point description |
Lower leg growth rate was assessed in growth population as change in the lower leg length from start to end of each 2-week treatment period, divided by time interval (number of days) between the two measurements, multiplied by 7. The Growth Population is defined as the Intent-To-Treat (ITT) population excluding participants having any of the following: did not fulfill growth-specific criteria; did not have growth assessment(s) at any defined time point; withdrawal from study due to adverse events related to major trauma to the legs, major surgery, or severe dehydration; received protocol prohibited medications that may affect short term growth, prior to randomization and during the study; protocol deviations defined in exclusion criteria for growth population. ITT Population consists of all randomized participants who received at least one dose of study drug.

Statistical analysis description |
Analysis performed using ANCOVA with covariates period-level baseline and subject-level baseline lower-leg length, age, gender, treatment and period.
Please note: To clarify system limitations, the comparison groups for statistical analysis are fluticasone furoate vs. placebo. Although the system adds the subjects in each analysis group together (total 116 below), there are only 58 subjects measured in this analysis as this is a crossover study with the same 58 subjects in each arm.

End point description |
An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect. Number of participants with AEs and SAEs have been presented. Two participants randomized to Sequence 1 (Placebo/FF), were treated with placebo in Period 1; however, neither received FF in Period 2, due to premature withdrawal.
