Study of QMF149 (150/80 µg) Compared With MF Twisthaler® (200 µg) in Patients With Asthma

The primary objective of this study was to demonstrate the superiority of QMF149 150/80 microgram o.d. (in the evening) delivered via Concept1 compared with MF 200 microgram o.d. (in the evening) delivered via Twisthaler® in terms of trough FEV1 after 12 weeks of treatment in adults and adolescents. The key secondary objective of this study was to demonstrate the superiority of QMF149 150/80 microgram to MF 200 microgram o.d. in terms of ACQ-7 after 12 weeks of treatment.

Inclusion criteria

• Patients with a documented diagnosis of asthma for a period of at least 3 months prior to Screening Visit
• Patients who have used low dose ICS , with or without controller (ie, LABA, Leukotriene Receptor Antagonist ) at stable dose for at least 1 month prior to Screening Visit
• Adult patients who are symptomatic at screening despite treatment with existing therapy.

Patients with ACQ-7 score ≥ 1.5 at Visit 101 and at Visit 102 (inadequately controlled).

• Adolescent patients :
• If taking only ICS (without LABA) and are symptomatic at screening despite treatment with low doses of ICS. These patients must have ACQ-7 score ≥ 1.5 at Visit 101 and at Visit 102 .
• If taking ICS (low dose)/ LABA, and have ACQ-7 score ≥1 and <1.5 at Visit 101: they must have ACQ-7 score≥1.5 at Visit 102 ( prior to randomization).
• Pre-bronchodilator FEV1≥ 60 % and < 90 % of the predicted normal value for the patient after withholding bronchodilators at both Visits 101 and 102
• Patients who demonstrate an increase in FEV1 of 12% and ≥ 200 mL within 30 minutes after administration of 400 microgram salbutamol/360 microgram albuterol (or equivalent dose) at Visit 101.

Exclusion criteria

• Patients who have smoked or inhaled tobacco products (including electronic cigarettes) within the 6 month period prior to Visit 1, or who have a smoking history of greater than or equal to 10 pack year.
• Patients who have had an asthma attack/exacerbation requiring systemic steroids or hospitalization (> 24 hours) or emergency room visit (≤ 24 hours) as follows:
• For adults: within 6 weeks of Screening Visit. If patients experience an asthma attack/exacerbation requiring systemic steroids or emergency room visit between Visit 1 and Visit 102 they may be re-screened 6 weeks after recovery from the exacerbation
• For adolescents: Severe asthma attack/exacerbation requiring systemic corticosteroids in the last 6 months, OR hospitalization (> 24 hours) due to severe asthma attack/exacerbation requiring systemic corticosteroids in the last 6 months, OR emergency room visit (≤ 24 hours) due to severe asthma attack/exacerbation requiring systemic corticosteroids within the last 6 months.
• Patients who ever required intubation for a severe asthma attack/exacerbation
• Patients with a clinical condition (eg. glaucoma, cataract and fragility fractures) which may be worsened by ICS administration (according to investigator's medical judgment )
• Patients who have had a respiratory tract infection or asthma worsening within 4 weeks prior to Screening Visit or between Visit 1and Visit 102. Patients may be re-screened 4 weeks after recovery from their respiratory tract infection or asthma worsening.
• Patients with any chronic conditions affecting the upper respiratory tract (eg. chronic sinusitis) which in the opinion of the investigator may interfere with the study.
• Patients with a history of chronic lung diseases other than asthma, including (but not limited to) COPD, sarcoidosis, interstitial lung disease, cystic fibrosis, clinically significant bronchiectasis and active tuberculosis.
• Patients with Type I diabetes or uncontrolled Type II diabetes.
• Patients with narcolepsy and/or insomnia.
• Patients on Maintenance Immunotherapy (desensitization) for allergies or less than 3 months prior to Visit 101 or patients on Maintenance Immunotherapy for more than 3 months prior to Visit 101 but expected to change throughout the course of the study.
• Patients with diagnosed rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption or with known intolerance to lactose or milk products.

• Patients who use a long acting muscarinic antagonist (LAMA) within 3 months prior to Visit 1.
