AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for teenagers and adults with a diagnosis of asthma who take tezepelumab or high-intensity standard treatment for severe asthma. It looks at serious heart and blood vessel events.

Age
12 years and older (up to 130 years).
Sex
All sexes can join.
Disease stage
Severe asthma.
Earlier treatment
Taking tezepelumab or high-intensity standard-of-care treatment for severe asthma during the study inclusion period. For the comparison, people cannot have been on other biologic drugs on the index date or within the 5-half-life clearance period.

Main reasons for not taking part

  • Less than 12 months of data available before the index date
  • Younger than 12 years at the index date
  • History of congenital heart disease or heart transplant
  • Non-fatal heart attack or stroke in the 180 days before the index date
  • Exposure to non-tezepelumab biologics on the index date or within the 5-half-life clearance period (comparison analysis)

The registry criteria, word for word

Show all 6 criteriaShow less

Who can take part

  • patients with a diagnosis of asthma receiving tezepelumab or high-intensity SOC treatment for severe asthma at any point during the study inclusion period

Who cannot take part

  • <12 months of data availability prior to index date,
  • history of congenital heart disease or heart transplant outcome-specific exclusion criterion applied for each objective will include the presence of non-fatal myocardial infarction or stroke and the specific outcome of interest in the 180 days prior to index date
  • matching criteria (including, among other variables, the type and duration of SOC exposure in the 12 months before index date and propensity score [PS] matching) will be applied to ensure exposed and unexposed patients' comparability
  • for comparative analysis, an additional exclusion criterion will be considered, i.e. exposure to non-tezepelumab biologics on index date or within the 5-half-life clearance period of the biologic
  • age <12 years at index date,

About the trial

What the trial wants to find out

The aim of this study is to evaluate the risk of serious adverse cardiovascular events in adolescent and adult patients with severe asthma taking tezepelumab compared to a population receiving standard of care treatment for severe asthma.

The 2 groups in the trial

  • tezepelumab severe asthma patients

    patients with a diagnosis of severe asthma receiving tezepelumab

    Treatment: Tezepelumab

  • tezepelumab unexposed asthma patients

    patients with a diagnosis of severe asthma receiving non-tezepelumab standard of care for severe asthma

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
