Study to Compare the Efficacy and Safety of QVM149 With QMF149 in Patients With Asthma

Novartis Pharmaceuticals3,092 enrolled

Overview

The purpose of the trial was to evaluate the efficacy and safety of two different doses of QVM149 (QVM149 150/50/80 μg and QVM149 150/50/160 μg via Concept1) over two respective QMF149 doses (QMF149 150/160 μg and QMF149 150/320) μg via Concept1 in poorly controlled asthmatics as determined by pulmonary function testing and effects on asthma control.

This study used a 52-week treatment, randomized, double-blind, double-dummy, parallel-group design. A total of 3092 asthma patients were randomized into the 5 treatment groups with a randomization ratio of 1:1:1:1:1 (approximately 617 patients per treatment group): QVM149 150/50/80 μg once daily (o.d.), QVM149 150/50/160 μg o.d., QMF149 150/160 μg o.d. and QMF149 150/320 μg o.d., all delivered via the Concept1 device, and salmeterol/fluticasone 50/500 μg twice daily (b.i.d.) delivered via Accuhaler. The 52 week treatment period was followed by a 30-day Follow-up. The primary objective of this study was to demonstrate superiority of either QVM149 150/50/80 μg o.d. to QMF149 150/160 μg o.d. or QVM149 150/50/160 μg o.d. to QMF149 150/320 μg o.d in terms of trough Forced Expiratory Volume in One Second (Trough FEV1) (FEV1) at Week 26, all delivered via Concept1.

Outcomes

Primary Outcomes

Trough Forced Expiratory Volume in 1 Second (Trough FEV1) of QVM149 Versus QMF149 at Week 26

Trough FEV1 was assessed by performing spirometric assessment. It is defined as average of the two FEV1 measurements taken 23 hr 15 min and 23 hr 45 min post-evening dose. FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation, measured through spirometry testing. The primary endpoint considered the following 2 comparison groups: * QVM149 150/50/80 μg o.d. compared with QMF149 150/160 μg o.d. both delivered via Concept1 * QVM149 150/50/160 μg o.d. compared with QMF149 150/320 μg o.d. both delivered via Concept1.

Time frame: 26 weeks

Secondary Outcomes

Asthma Control Questionnaire (ACQ-7) at Week 26 and Week 52

The ACQ-7 measured asthma symptom control and consists of 7 items: 5 on symptom assessment, 1 on rescue bronchodilator use and 1 on airway calibre (FEV1 % predicted). All 7 questions of the ACQ-7 were equally weighted. Items 1-5 were scored along a 7-point response scale, where 0 = totally controlled and 6 = severely uncontrolled. Item 6 is scored between 0 = no rescue medication and 6 = More than 16 puffs/inhalations most days. The 7th item was scored by the investigator based on the FEV1 % predicted from the masterscope at the site (i.e., Score = 0 means \> 95% of predicted FEV1, 1 = 90 - 95%, 2 = 80 - 89%, 3 = 70 - 79%, 4 = 60 - 69%, 5 = 50 - 59%, and Score = 6 means \< 50% of predicted FEV1). The ACQ-7 total score reported below was calculated as the mean of scores of all 7 items and ranged between 0 and 6, with higher scores indicating worse asthma symptom control.

FEF is the flow (or speed) of air coming out of the lung during the middle portion of a forced expiration. Trough FEF25-75% is defined as average of the two FEF25-75% measurements taken 23 hr 15 min and 23 hr 45 min post-evening dose. It was assessed by performing spirometric assessment.

Time frame: Up to Week 52

Change From Baseline in Morning and Evening Peak Expiratory Flow Rate (PEF) Over 26 and 52 Weeks of Treatment

PEF is a person's maximum speed of expiration. All the participants were instructed to record PEF twice daily using a mini Peak Flow Meter device, once in the morning (before taking the morning dose) and once approximately 12 h later in the evening (before taking the evening dose) at home. At each timepoint, the participant was instructed to perform 3 consecutive manoeuvres within 10 minutes. These PEF values were captured in the e-PEF/diary. The best of 3 values were used.

Time frame: Baseline, 26 weeks, 52 weeks

Change From Baseline in Percentage of Asthma Symptom-free Days Over 52 Weeks

All participants were provided with an electronic diary (e-Diary) to record clinical symptoms. They were instructed to routinely complete the e-Diary twice daily at the same time each morning and again approximately 12 hours later in the evening. The e-Diary was reviewed at each visit until study completion. Asthma symptoms free days are days with no daytime symptoms, no night-time awakenings and no symptoms on awakening. The daytime asthma symptom score was based on the daily e-diary recordings by participants with respect to shortness of breath, wheeze, cough, chest tightness, and impact on usual daily activities due to symptoms.

Time frame: Baseline, 52 weeks

Change From Baseline in Percentage of Days With no Daytime Symptoms Over 52 Weeks

All participants were provided with an electronic diary (e-Diary) to record clinical symptoms. They were instructed to routinely complete the e-Diary twice daily at the same time each morning and again approximately 12 hours later in the evening. The e-Diary was reviewed at each visit until study completion. For days with no daytime symptoms, all 5 evening questions must have a score = 0 with respect to shortness of breath, wheeze, cough, chest tightness and impact on usual daily activities due to symptoms, each with scores from 0 (no problems) to 4 (very severe problems).

Time frame: Baseline, 52 weeks

Percentage of Patients Achieving the Minimal Clinically Important Difference (MCID) ACQ ≥ 0.5 at Week 26 and Week 52

Change from baseline in ACQ-7 scores of ≤ 0.5 was defined as minimal clinically important difference and were considered clinically meaningful. The ACQ-7 measured asthma symptom control and consists of 7 items: 5 on symptom assessment, 1 on rescue bronchodilator use and 1 on airway calibre (FEV1 % predicted). All 7 questions of the ACQ-7 were equally weighted. Items 1-5 were scored along a 7-point response scale, where 0 = totally controlled and 6 = severely uncontrolled. Item 6 is scored between 0 = no rescue medication and 6 = More than 16 puffs/inhalations most days. The 7th item was scored by the investigator based on the FEV1 % predicted from the masterscope at the site (i.e., Score = 0 means \> 95% of predicted FEV1, 1 = 90 - 95%, 2 = 80 - 89%, 3 = 70 - 79%, 4 = 60 - 69%, 5 = 50 - 59%, and Score = 6 means \< 50% of predicted FEV1). The total score was calculated as the mean of all questions.

Time frame: 26 weeks, 52 weeks

Time to First Hospitalization for Asthma Exacerbation

Time from start of treatment until the first event (hospitalization for asthma exacerbation) or censoring. Patients without the event were considered as censored at the date of last treatment + 1 day. For patients having the event, the start date of the hospitalization was considered to calculate the time to event (i.e., the number of days from start of treatment up to the event start date).

Time frame: 52 weeks on average, up to 416 days

Time to First Asthma Exacerbation by Exacerbation Category

Time from start of treatment until the first event (asthma exacerbation) or censoring. Patients without the event were considered as censored at the date of last treatment + 1 day. For patients having the event, the start date of the exacerbation was considered to calculate the time to event (i.e., the number of days from start of treatment up to the event start date). The exacerbation categories were: All (mild, moderate and severe), combination of moderate or severe and severe.
