E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To show therapeutic equivalence (i.e. non-inferiority) of Salmeterol/Fluticasone DPI HEXAL to SeretideTM AccuhalerTM in adolescent and adult patients with moderate-to-severe persistent asthma for both the low dose combination (50 µg/100 µg of salmeterol/fluticasone per actuation, 2x1 actuation per day) and the high dose combination (50 µg/500 µg of salmeterol/fluticasone per actuation, 2x1 actuation per day). Conclusion of non-inferiority will for both dose combinations be based on 2 primary efficacy variables for each dosage leven since the treatment effects for fluticasone are different from salmeterol: abolute change in FEV1 and FEV1 AUC 0-12 after 12 weeks of treatment relative to baseline FEV1. |

E.2.2 | Secondary objectives of the trial |
Efficacy: Change in FEV1 from baseline (Visit 0) to Visit 3; Development of FEV1 and FEV1 % predicted over the course of the study; Mean change in morning pre-dose FEV1 and PEF from baseline to evaluation period; Development of FVC; Time to onset of action at Visit 6; Development of PEF over the course of the study; Change in asthma symptoms scores and total asthma symptoms score over time; Frequency of use of reliever medication; Incidence and severity of asthma exacerbations; Number of patients discontinuing the study due to asthma worsening ; Overall assessment of efficacy. Safety: Incidence and severity of AEs and drug-related AEs; Clinically relevant changes in laboratory parameters, vital signs, ECG and physical examination parameters; Incidence of patients with oral candidiasis or voice hoarseness; Clinically relevant changes in morning serum cortisol levels; Serum cortisol concentration-time profiles at Visit 6; Overall assessment of tolerability of the IP. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary aim of this study is to show therapeutic equivalence (i.e. non-inferiority) of Salmeterol/Fluticasone DPI HEXAL to SeretideTM AccuhalerTM in adolescent and adult patients with moderate-to-severe persistent asthma for both the low dose combination (50 µg/100 µg of salmeterol/fluticasone per actuation, 2x1 actuation per day) and the high dose combination (50 µg/500 µg of salmeterol/fluticasone per actuation, 2x1 actuation per day). Conclusion of non-inferiority will for both dose combinations be based on two primary efficacy variables for each dosage level since the treatment effects for fluticasone are different from salmeterol. Non-inferiority based on change in FEV1 will be concluded if the resulting one-sided 97.5% confidence interval for the difference between LSMEANs of the two treatment groups with respect to the absolute change in FEV1 (Visit 6 minus Visit 0) lies entirely within the pre-specified interval [-200 ml; infinite]. Non-inferiority with respect to FEV1 AUC0-12 after 12 weeks of treatment relative to baseline FEV1 will be concluded if the resulting one-sided 97.5% confidence interval for the ratio of the LSMEANs of the two treatment groups, µtest / µref, lies entirely within the pre-specified interval [80%; infinite].
