Brief Summary

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

A study involving primary data collection within real-world settings of participants who initiate treatment with tezepelumab for severe uncontrolled asthma. This study will complement evidence obtained from randomized controlled trials and provide new data focusing on the holistic and patient reported outcome (PRO).

Detailed Description

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

This is a 12-month, multi-country, multi-center, prospective, non-comparative and non-interventional (observational), post-reimbursement real-world evidence study that will assess asthma symptom control, lung function, and patient-reported outcomes including health-related quality of life after tezepelumab treatment initiation in participants with severe asthma in Europe and Canada. This study is planned to be conducted in several countries including but not limited to Canada, Germany, Denmark, Switzerland, and Sweden.

Participants will be followed for a maximum period of 52 weeks after tezepelumab treatment initiation, irrespective of treatment discontinuation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Prospective Cohort

Participants with severe uncontrolled asthma will receive tezepelumab. Relevant demographics, baseline clinical data, and asthma control questionnaire-6 (ACQ-6) will be retrospectively collected. All patient reported outcomes (PROs) will be prospectively collected. Other outcomes of interest (tezepelumab patterns of utilization, lung function, asthma exacerbations, medication use, and healthcare resource utilization \[HRU\]) will be collected at baseline (retrospective collection for 52-week pre-index period during enrolment) and prospectively collected during enrolment for participants who enroll into the study before the first dose of tezepelumab, and for a period of up to 52 weeks (at Weeks 4, 12, 24, and 52) after the index date. The index date is defined as the date when participants receive the first dose of tezepelumab.
