E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to show that CHF 1535 50/6µg pMDI, 2 inhalations bid (total daily dose: BDP 200μg / FF 24μg) using AeroChamber Plus™ spacer device is non-inferior to a corresponding free combination of BDP 50μg pMDI, 2 inhalations bid (total daily dose: 200μg) plus FF 6μg pMDI, 2 inhalations bid (total daily dose: 24μg) using AeroChamber Plus™ spacer device in terms of lower leg growth rate (LLGR), measured by knemometry, over a 2-week treatment period |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate that CHF 1535 50/6 pMDI is non-inferior to a corresponding free combination dose of extrafine BDP 50μg HFA plus Formoterol Fumerate (FF) 6μg in terms of pulmonary function test and safety parameters. |

E.5 End points |
E.5.1 | Primary end point(s) |
Lower Leg Growth Rate (LLGR) after 2-week treatment with CHF 1535 50/6µg pMDI and free combination of BDP 50μg pMDI plus FF 6μg pMDI will be compared using an ANCOVA model. The model will include treatment and period as fixed effects, subject as a random effect and the baseline LLGR as covariate. Baseline growth rate is the change in lower leg length from beginning to end of run-in period, divided by the time interval between the two measurements.
The difference between treatments for adjusted treatment means will be presented with a two-sided 95% confidence interval. If the lower bound of this interval is greater than or equal to -0.20 mm/week non inferiority will be declared.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1) LLGR after each of the two active treatments compared to LLGR at the end of placebo run-in period. An ANOVA analysis with the three treatments (two active treatments and run-in placebo) and subjects as a random effect will be performed. The results of the analysis will be presented with the estimated differences between each of the two treatments and the placebo, with a 95% confidence interval, and a p-value for the treatment difference being equal to 0.
2) The comparison of 24-hour urinary free cortisol/creatinine levels after treatment with CHF 1535 and with free combination of BDP and formoterol will be done using the same model as described in the primary endpoint analysis but without testing for non-inferiority.
Consistently the comparison of 24-hour urinary free cortisol excretion/creatinine after each of the two active treatments with the end of placebo run-in period will be done with the same model used for the LLGR endpoint.
3) Incidence of adverse events (coded with MedDRA) as well as vital signs will be presented by descriptive statistics only.
