Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Adults and adolescents greater than or equal to (>=)12 years of age, at the time of signing the informed consent/assent.
  • Participants must have a documented physician diagnosis of asthma for >=2 years that meets the National Heart, Lung, and Blood Institute guidelines (NHLBI) or Global Initiative for Asthma (GINA) guidelines and
  • Eosinophilic phenotype: participants who have, or with high likelihood of having, asthma with an eosinophilic phenotype as per randomization criteria, and
  • Exacerbation history: participants who have previously confirmed history of >=2 exacerbations requiring treatment with systemic corticosteroid (CS) (Intramuscular [IM], Intravenous [IV], or oral), in the 12 months prior to Visit 1, despite the use of medium to high-dose ICS. For participants receiving maintenance CS, the CS treatment for the exacerbations must have been a two-fold dose increase or greater.
  • Persistent airflow obstruction as indicated by (i) For participants >=18 years of age at Visit 1, a pre-bronchodilator FEV1 less than (<)80 percent (%) predicted National Health and Nutrition Examination Survey (NHANES III) recorded at Visit 1.
  • For participants 12-17 years of age at Visit 1: A pre-bronchodilator FEV1 <90% predicted (NHANES III) recorded at Visit 1 or FEV1: Forced Vital Capacity (FVC) ratio <0.8 recorded at Visit 1.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Annualized Rate of Clinically Significant Exacerbations up to 52 Weeks

    Clinically significant exacerbations recorded were defined as worsening of asthma requiring the use of systemic corticosteroids (CS) [such as intramuscular (IM), intravenous (IV) or oral] and/or hospitalization and/or Emergency Department (ED) visit. For all participants, IV or oral steroids (e.g., prednisone) for at least 3 days or a single IM corticosteroid dose is required. For participants on maintenance systemic corticosteroids, at least double the existing maintenance dose for at least 3 days is required. Exacerbations recorded in the electronic case report form (eCRF) were considered as verified clinically significant exacerbations and included in the primary analysis. Exacerbations separated by less than 7 days was treated as a continuation of the same exacerbation.

    Measured: Up to Week 52

Secondary outcomes (6)

  1. Change From Baseline in St. George's Respiratory Questionnaire (SGRQ) Total Score at Week 52

    The SGRQ is a 50-item patient-reported outcome tool used to measure Quality of Life in participants with airway obstruction diseases. The questions are designed to be self-completed by the participant. The total score was calculated by the symptom score, activity and impact score; and summarizing the impact of the disease on overall health status on 0-100 rating scale. Scores are expressed as a percentage of overall impairment where 100 representing worst possible health status and 0 indicating best possible health status. Higher scores indicating greater impairment of quality of life. Change from Baseline was defined as value at the indicated time point minus Baseline value.

    Measured: Baseline (Day 1) and Week 52

  2. Change From Baseline in Asthma Control Questionnaire-5 (ACQ-5) Score at Week 52

    The ACQ-5 is a five-item questionnaire developed as a measure of participants asthma symptom control. The questions are designed to be self-completed by the participant. The 5 questions enquired to recall how their asthma had been during the previous week and to respond about the frequency and/or severity of symptoms (nocturnal awakening, waking in the morning, activity limitation, shortness of breath and wheezing). The overall ACQ-5 response option is the mean score of all 5 questions representing 0 with no impairment/limitation and 6 as total impairment/ limitation. Higher scores indicated more limitations and lower score with better asthma control. Change from Baseline was defined as value at the indicated time point minus Baseline value.

    Measured: Baseline (Day 1) and Week 52

  3. Change From Baseline in Pre-Bronchodilator Forced Expiratory Volume in One Second (FEV1) At Week 52

    Forced Expiratory Volume in One Second (FEV1) is defined as the volume of air that can be forced out in one second after taking a deep breath by a person and will be measured by spirometry testing. Change from Baseline in clinic pre-bronchodilator FEV1 was determined. Change from Baseline was defined as value at the indicated time point minus Baseline value.

    Measured: Baseline (Day 1) and Week 52

  4. Change From Baseline in Asthma Nighttime Symptom Diary (ANSD) Weekly Mean Score at Week 52

    The ANSD is a 6-item self-administered patient reported diary developed by Patient Related Outcomes (PRO) Consortium's Asthma Working Group to facilitate comprehensive and reliable assessment of asthma symptoms from a participant's perspective. Participants were required to rate the severity of symptoms in 3 core categories: breathing symptoms (wheezing, shortness of breath), chest symptoms (chest tightness, chest pain) and cough. The ANSD was to be completed before going to bed and refers to asthma symptoms during the day. Symptoms are rated at their worst using an 11-point numeric rating scale ranging from 0 (None) to 10 (As bad as you can imagine). Higher scores indicate more severe symptoms. Mean daily scores of ANSD was calculated by weekly intervals. The baseline values were defined as the average score from Day -7 to Day -1 inclusive (at least 4 days must be non-missing). Change from Baseline was defined as value at each time point minus Baseline value.

    Measured: Baseline to Week 52

  5. Change From Baseline in Asthma Daily Symptom Diary (ADSD) Weekly Mean Score at Week 52

    The ADSD is a 6-item self-administered patient reported diary developed by patient related outcomes (PRO) Consortium's Asthma Working Group to facilitate comprehensive and reliable assessment of asthma symptoms from a participant's perspective. Participants were required to rate the severity of symptoms in 3 core categories: breathing symptoms (wheezing, shortness of breath), chest symptoms (chest tightness, chest pain) and cough. The ADSD was to be completed upon waking and refers to asthma symptoms during the night-time. Symptoms are rated at their worst using an 11-point numeric rating scale ranging from 0 (None) to 10 (As bad as you can imagine). Higher scores indicate more severe symptoms. Mean daily scores of ADSD was calculated by weekly intervals. The baseline values were defined as the average score from Day -7 to Day -1 inclusive (at least 4 days must be non-missing). Change from Baseline was defined as value at each time point minus Baseline value.

    Measured: Baseline to Week 52

  6. Annualized Rate of Exacerbations Requiring Hospitalization and/or Emergency Department (ED) Visit up to 52 Weeks

    Annualized Rate of exacerbations of asthma were defined as worsening of asthma which required use of systemic corticosteroids (CSs) and/or hospitalization and/or Emergency Department (ED) visit. For all participants, IV or oral steroids (e.g., prednisone) for at least 3 days or a single IM CS dose is required. For participants on maintenance systemic CSs, at least double the existing maintenance dose for at least 3 days is required. Exacerbations separated by less than 7 days will be treated as a continuation of the same exacerbation. Exacerbations Requiring Hospitalization and/or ED Visit are reported here.

    Measured: Up to Week 52

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Annualized Rate of Clinically Significant Exacerbations up to 52 Weeks (time frame: Up to Week 52). It is what the study was designed to measure, not a finding.
