Outcome Measures

Primary Outcomes (4)

  • Annualized asthma exacerbation rate (AAER)

    Asthma exacerbation will be defined by worsening of asthma symptoms that leads to temporary bolus/burst of systemic corticosteroids for at least 3 consecutive days, or an emergency department (ED) or urgent care visit due to asthma that required systemic corticosteroid (SCS), and/or inpatient hospitalization (≥24 hours) due to asthma. The AAER is based on exacerbations reported by the investigator over 52 weeks. The exacerbation rate will be compared between the 12 month period before (baseline period) and the 12 month period after initiation of tezepelumab (up to study Week 52 - study period).

    Baseline period up to study Week 52

  • Proportion of participants with asthma exacerbations

    The proportion of participants with asthma exacerbations in the 12 month periods before (baseline period) and after initiation of tezepelumab (study period) (up to study Week 52 - study period) will be assessed.

    Baseline period up to study Week 52

  • Proportion of participants who completed the 52 -week study period with any reduction in total number of asthma exacerbations

    The proportion of participants who completed the 52 -week study period following tezepelumab initiation with any reduction, at least 50% reduction, and 100% reduction in total number of asthma exacerbations will be assessed.

    Baseline period up to study Week 52

  • Cumulative asthma exacerbation days

    The cumulative asthma exacerbation days over 52 weeks before (baseline period) and after initiation of tezepelumab (study period) will be assessed.

    Baseline period up to study Week 52

Secondary Outcomes (32)

  • Time to first asthma exacerbation

    Week 0 to Week 52

  • Rate of asthma exacerbations associated with hospitalizations

    Baseline period up to study Week 52

  • Rate of asthma exacerbations associated with emergency department /urgent care (ED/UC) visits

    Baseline period up to study Week 52

  • Rate of asthma exacerbations associated with hospitalizations or ED/UC visits over

    Baseline period up to study Week 52

  • Proportion of participants with asthma exacerbations associated with hospitalizations or ED/UC visits

    Baseline period up to study Week 52

  • +27 more secondary outcomes

Other Outcomes (1)

  • Number of participants with serious adverse events, adverse events that lead to tezepelumab treatment discontinuation, and adverse events of special interest

    Week 0 to Week 52

Study Arms (1)

Tezepelumab

EXPERIMENTAL

Participants will be receiving 210 mg of tezepelumab every 4 weeks (Q4W) from Week 0 until Week 48.

Drug: Tezepelumab

Interventions

Participants will be receiving subcutaneous injection of tezepelumab.

Eligibility Criteria

Age12 Years - 130 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female participant must be 12 years of age or older, at the time of signing the informed consent form or assent.
  • Documented physician-diagnosed asthma for at least 12 months prior to enrollment and confirmed by the Investigator not to be due to alternative diagnoses.
  • Documented treatment with medium- to high dose ICS as per Global Initiative for Asthma (GINA) guidelines (GINA 2021) for at least 12 months prior to enrollment.
  • Use of additional asthma maintenance controller medication(s) in addition to ICS for at least 12 months prior to enrollment. The additional maintenance controller medication may be contained in a combination product (eg, ICS/ long-acting β-agonist (LABA)).
  • Documented history of at least 2 asthma exacerbations during the 12 months prior to enrollment.
  • Physician decision that participant is eligible for treatment with tezepelumab according to the approved United States product insert (USPI).
  • Currently receiving care from specialist physicians (eg, pulmonologists and/or allergists).
  • Provision of signed and dated written informed consent form.

You may not qualify if:

  • Any contraindication to tezepelumab as per the US approved product label or in the opinion of the Investigator.
  • Comorbid diagnosis of severe or very severe chronic obstructive pulmonary disease (COPD) per GOLD guidelines (GOLD 2021).
  • Use of biologics that are approved for the treatment of asthma within 4 months or 5 half- lives (whichever is longer) prior to enrollment.
  • Participation in an interventional clinical trial for asthma within 12 months prior to enrollment.
  • Judgment by the Investigator that the participant is unlikely to comply with study procedures, restrictions, and requirements.
