| E.2.1 | Main objective of the trial |
Main Phase
To demonstrate the superiority of medium-dose BDP/FF/GB pMDI compared to high-dose BDP/FF pMDI in terms of the proportion of subjects exhibiting on average NPAL over 26 weeks of treatment in the study sub-population with PAL at screening.
•A subject is defined as having PAL at screening if their postbronchodilator (salbutamol) FEV1/FVC ratio is < 0.7.
•A subject is defined as having NPAL during the treatment period if the mean of their 2h post-dose FEV1/FVC ratios collected during the 26-week treatment period is ≥ 0.7.
OLE Phase
To assess the proportion of subjects whose asthma remains "Adequately Controlled":
• on MS BDP/FF/GB at the end of the OLE phase in subjects with previously "Adequately Controlled Asthma" (Cohort 1 on HS BDP/FF, Cohort 4 on MS BDP/FF/GB)
• on HS BDP/FF/GB at end of the OLE phase in subjects with previously "Uncontrolled Asthma"(Cohort 2 on MS BDP/FF/GB, cohort 3 on HS BDP/FF) at the end of the main phase. |
|
| E.2.2 | Secondary objectives of the trial |
| To demonstrate the superiority of medium-dose BDP/FF/GB pMDI (100/6/12.5 µg, 2 puffs bid) compared to high dose BDP/FF pMDI (200/6 µg, 2 puffs bid) in terms of change from baseline in pre-dose FEV1 at Week 26 in the study sub-population meeting PAL criterion at screening. |

- to correctly use the e-Diary/e-Peak flow meter.
11.Female subjects:
a.Woman of Childbearing Potential or b.Female patient of nonchildbearing potential: Please refer to the protocol.
OLE phase
1. Informed consent: Subject's electronic (preferred option) or written informed consent obtained prior to any study related procedures;
2. Participation in MiSTIC study main phase: Subjects enrolled in MiSTIC main phase, who did not discontinue from the main phase study treatment before Week 26
and with available data to allow classification into one of the two categories "Adequately Controlled Asthma" or "Uncontrolled Asthma" at the end of the main phase;
3. A willingness and ability:
-To correctly use the pMDI inhalers;
-To perform all trial related procedures including technically acceptable pulmonary function tests;
-To correctly use the e-Diary and home-spirometry device;
-To correctly use the technology enabling remote visits and home supervised spirometry assessments. This applies only to countries where remote visits are allowed as per local regulations and for subjects willing to participate to remote assessments. The home spirometry will be supervised by site personnel during the remote visits.
4. Treatment compliance during main phase: Subjects with main phase study treatment compliance = 70%
5.Female subjects:
a.Woman of Childbearing Potential or b.Female patient of non childbearing potential: Please refer to the protocol. |

| E.4 | Principal exclusion criteria |
Main Phase
1.Pregnant or lactating woman where pregnancy is defined as the state of a female after conception and until termination of the gestation, confirmed by a positive pregnancy test (serum pregnancy test to be performed at screening visit and urine pregnancy test to be performed prior to randomisation);
2.Run-in compliance to study drug and e-Diary completion < 50% at randomisation;
3.History of "high risk" asthma: History of near fatal asthma or hospitalisation for asthma in an intensive care unit which, in the judgement of the Investigator, may place the subject at undue risk if enrolled in this study;
4.Recent asthma exacerbation: hospitalisation, emergency room
admission or use of systemic corticosteroids for an asthma exacerbation in the 4 weeks prior to screening visit or during the run-in period;
Note: Subjects experiencing an exacerbation during the run-in period may be re-screened once, at least 4 weeks after recovery.

Localised carcinoma (e.g. basal cell carcinoma, in situ carcinoma of the cervix adequately treated, …) is acceptable;

Note: Subjects with permanent AF (for at least 6 months prior screening) with a resting ventricular rate < 100/min, controlled with a rate control strategy (i.e. selective β blocker, calcium channel blocker, pacemaker placement, digoxin or ablation therapy) can be considered for enrolment;
