Study of Efficacy and Safety of QAW039 in Patients With Severe Asthma Inadequately Controlled With Standard of Care Asthma Treatment.

This study aimed to determine the efficacy and safety of QAW039 and QAW039 450 mg compared to placebo, when added to GINA (Global Initiative for Asthma) steps 4 and 5 standard-of- care (SoC) asthma therapy (GINA 2016) in the following two populations:

* patient with inadequately controlled severe asthma and high eosinophil counts (eosinophil count at Visit 1 ≥250 cells/ µl) (sub-population) * patients with inadequately controlled severe asthma (overall study population) Inadequate control is defined as partly controlled or uncontrolled asthma (GINA 2016)

About this study

This study used a randomized, multicenter, double-blind, placebo-controlled parallel-group design in which QAW039 (150 mg and 450 mg) or placebo was added to GINA steps 4 and 5 asthma therapy.

The study included:

  • Screening period of up to 2 weeks to assess eligibility;
  • Run-in period of approximately 2 weeks and a maximum of 6 weeks on placebo to collect baseline data for efficacy variables and compliance with the Electronic Peak Flow/ eDiary device. Upon completion of the run-in period, all patients who met the eligibility criteria were randomized to one of three treatments: QAW039 150 mg or QAW039 450 mg or placebo once daily in a ratio of 1:1:1.
  • Treatment period of 52 weeks (assessment period for all Primary and Secondary Outcome Measures). Clinic visits were scheduled approximately 4 weeks after randomization and then at approximately 8-week intervals during the active-treatment period. Phone calls occurred at specified time points between visits occurring at 8-week intervals. Patients who had successfully completed 52 weeks of treatment in this study were offered an optional participation in a safety study (CQAW039A2315).
  • Follow-up period of 4 weeks, investigational and drug-free, following the last dose of study drug. A follow-up visit occurred approximately 4 weeks (i.e., approximately 30 days) following the last dose of study therapy to complete safety assessments and pregnancy testing (if applicable).

The follow-up period applied to all patients except those patients who had entered the optional safety study (CQAW039A2315) directly after the Week 52 study visit

Primary outcomes

  1. Rate of Moderate-to-severe Asthma Exacerbations During the 52-week Treatment Period in High Eosinophils Subpopulation

    Time frame: 52 weeks

    A severe asthma exacerbation is defined as treatment with 'rescue' systemic corticosteroids for greater than or equal to 3 days and hospitalization; or treatment with 'rescue' systemic corticosteroids for greater than or equal to 3 days and emergency department visit (greater than 24 hours*); or death due to asthma.

    A moderate asthma exacerbation is defined as treatment with 'rescue' systemic corticosteroids for greater than or equal to 3 days either as an outpatient or in emergency department visits (Emergency department visit less than or equal to 24 hours). The high eosinophils subpopulation consists of all patients with blood eosinophil count ≥ 250 cells/μL at baseline.

  2. Rate of Moderate-to-severe Asthma Exacerbations During the 52-week Treatment Period in Overall Population

    Time frame: 52 weeks

    A severe asthma exacerbation is defined as treatment with 'rescue' systemic corticosteroids for greater than or equal to 3 days and hospitalization; or treatment with 'rescue' systemic corticosteroids for greater than or equal to 3 days and emergency department visit (greater than 24 hours*); or death due to asthma.

    A moderate asthma exacerbation is defined as treatment with 'rescue' systemic corticosteroids for greater than or equal to 3 days either as an outpatient or in emergency department visits (Emergency department visit less than or equal to 24 hours).

Secondary outcomes

  1. Change From Baseline to Week 52 in Asthma Quality of Life Questionnaire for Participants 12 Years and Older (AQLQ+12) Score in High Eosinophils Subpopulation

    Time frame: Baseline, Week 52

    AQLQ is a 32-item instrument administered as a self-assessment. AQLQ+12 is a modified version of AQLQ developed to measure functional impairments of participants aged 12-70 years. It is divided into 4 domains: activity limitation, symptoms, emotional function, and environmental stimuli. Participants were asked to recall their experiences during the last 2 weeks and respond to each question on a 7-point scale (1=severe impairment, 7=no impairment), where higher scores indicated "better quality of life." Overall AQLQ+12 score is the mean of all 32 responses. The high eosinophils subpopulation consists of all patients with blood eosinophil count ≥ 250 cells/μL at baseline.

  2. Change From Baseline to Week 52 in Asthma Control Questionnaire-5 (ACQ-5) Score in High Eosinophils Subpopulation

    Time frame: Baseline, Week 52

    The ACQ-5 is a five-item, self-completed questionnaire, which is used as a measure of asthma control of a participant. The five questions (concerning nocturnal awakening, waking in the morning, activity limitation, shortness of breath and wheeze) enquire about the frequency and/or severity of symptoms over the previous week. The response options for all these questions range from zero (no impairment/limitation) to six (total impairment/ limitation) scale. The ACQ-5 score is the average of the individual item scores and ranges from 0 to 6. Higher scores indicates worsening of condition. The high eosinophils subpopulation consists of all patients with blood eosinophil count ≥ 250 cells/μL at baseline.

  3. Change From Baseline to Week 52 in Pre-dose Forced Expiratory Volume in 1 Second (FEV1) in High Eosinophils Subpopulation

    Time frame: Baseline, Week 52

    Forced Expiratory Volume in one second (FEV1) is calculated as the volume of air forcibly exhaled in one second as measured by a spirometer. Baseline is defined as the last available FEV1 measurement taken prior to the first dose of randomized study drug. The high eosinophils subpopulation consists of all patients with blood eosinophil count ≥ 250 cells/μL at baseline.

  4. Change From Baseline to Week 52 in Asthma Quality of Life Questionnaire for Participants 12 Years and Older (AQLQ+12) Score in Overall Population

    Time frame: Baseline, Week 52

    AQLQ is a 32-item instrument administered as a self-assessment. AQLQ+12 is a modified version of AQLQ developed to measure functional impairments of participants aged 12-70 years. It is divided into 4 domains: activity limitation, symptoms, emotional function, and environmental stimuli. Participants were asked to recall their experiences during the last 2 weeks and respond to each question on a 7-point scale (1=severe impairment, 7=no impairment), where higher scores indicated "better quality of life." Overall AQLQ+12 score is the mean of all 32 responses.

  5. Change From Baseline to Week 52 in Asthma Control Questionnaire-5 (ACQ-5) Score in Overall Population

    Time frame: Baseline, Week 52

    The ACQ-5 is a five-item, self-completed questionnaire, which is used as a measure of asthma control of a participant.

The response options for all these questions range from zero (no impairment/limitation) to six (total impairment/ limitation) scale. The ACQ-5 score is the average of the individual item scores and ranges from 0 to 6. Higher scores indicates worsening of condition.

  6. Change From Baseline to Week 52 in Pre-dose Forced Expiratory Volume in 1 Second (FEV1) in Overall Population

    Time frame: Baseline, Week 52

    Forced Expiratory Volume in one second (FEV1) is calculated as the volume of air forcibly exhaled in one second as measured by a spirometer. Baseline is defined as the last available FEV1 measurement taken prior to the first dose of randomized study drug.
