Brief summary
The purpose of this trial was to demonstrate that the efficacy of two treatment arms of the fixed-dose combination product QVM149 was non-inferior to the efficacy of the free combination arm of salmeterol/ fluticasone+ tiotropium in uncontrolled moderate to severe asthmatic patients. The planned duration of treatment in this study was 24 weeks, followed up by a 7-day follow-up period.
Detailed description
This study used a randomized, partially-blinded, 24-week, parallel-group, non-inferiority, open-label active controlled design. The study was partially open-label. Investigators and patients had knowledge of treatment allocation between QVM149 and/or comparator, however the QVM149 strength allocation was masked. The global sponsor team responsible for data review and analysis was blinded to all treatment allocations The study consisted of a screening period of up to 1-week, run-in period of 2-weeks, randomized treatment period of 24-weeks, and a follow-up period of 1-week. At the screening visit, informed consent was obtained, and current and prohibited medications were reviewed. Rescue medication was provided to all patients who met the eligibility criteria and was to be used on an as needed basis throughout the study. At the run-in visit, inclusion and exclusion criteria were reviewed and the patients were supplied with open-label long acting β2-adrenergic agonist/inhaled corticosteroids (LABA/ICS) salmeterol/fluticasone 50/250 μg b.i.d or 50/500 μg b.i.d to match their ICS background medication dose to be stopped at randomization visit. All patients who met the eligibility criteria were randomized to 1 of 3 treatment arms with a randomization ratio of 1:1:1. The patients were stratified at randomization according to the ICS dose component of background ICS/LABA (medium or high dose) and region. Treatment period visits were scheduled every 8 weeks. The study used two doses of QVM149 (high dose \[150/50/160 μg\] and a medium dose \[150/50/80 μg\] o.d. delivered via Concept1 inhaler) and a comparator treatment (salmeterol/fluticasone 50/500 μg b.i.d. delivered via Accuhaler® plus tiotropium 5 μg o.d delivered via Respimat®). All randomized patients were contacted (by telephone) 7 days following the last dose of study medication or last visit, whichever was later, for Safety Follow-up visit.

Study design
Masking description
The free triple combination of salmeterol/fluticasone + tiotropium was open label, for which investigators and patients had full knowledge that the patient had been assigned free triple combination comparator treatment. Within the two QVM149 treatment arms patients, investigator staff, and persons performing the assessments, remained blind to the identity of the actual QVM149 treatment dose but had full knowledge that the patient had been assigned QVM149 as study treatment. The data analysts and sponsor team were blinded to Case Report Forms that reveal the treatment arm. Randomization data and treatment codes were kept strictly confidential until the time of unblinding, and was not accessible by anyone else involved in the study.

It consists of 4 domains: symptoms, activity limitation, emotional funtion, and emotional stimuli. The overall score is calculated as the mean of 32 items.

All seven items are scored on a 7-point Likert scale, with 0 indicating total control and 6 indicating poor control. The questions are equally weighted and the total score is the mean of the seven items. Higher score indicates worst symptoms. The first 6 questions of the ACQ-7 were completed by the participant while the last question was completed by the study investigator using data from the Master Scope spirometer. A negative change from baseline indicates improvement in lung function. |

Percentage of Patients Achieving the Minimally Clinically Important Difference (MCID) Change From Baseline AQLQ ≥ 0.5
The AQLQ is a 32-item asthma specific questionnaire designed to measure functional impairments that are most important to patients with asthma, with a recall time of two weeks and each question to be answered on a 7-point scale, where 1=totally limited/problems all the time and 7= not at all limited/no problems. It consists of 4 domains: symptoms, activity limitation, emotional function and environmental stimuli. The overall score is calculated as the mean of 32 items. Higher AQLQ scores indicate better health-related quality of life. An improvement of 0.5 points in AQLQ score is considered to be the minimally clinically important difference in asthma.
