Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To asses effectiveness and safety of tezepelumab in adult and adolescent participants with severe asthma including several under-studied populations in the United States.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, single-arm, open-label, Post-authorization, Phase 4 study to assess the effectiveness of tezepelumab in the United States (US) among a real-world population of adults and adolescent participants with asthma requiring medium-dose to high-dose inhaled corticosteroids (ICS), with additional controller(s) for at least 12 months with documented history of at least 2 asthma exacerbations during the year prior to enrolment. The total duration of the study for each participant will be approximately 56 weeks. Approximately 400 participants will be enrolled. Participants will receive tezepelumab via subcutaneous injection at the study site, over a 48-week treatment period. The study also includes a post-dosing follow-up period from Weeks 48 to 52.

* 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).

* Provision of signed and dated written informed consent form.

Exclusion Criteria

* 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.
