|ClinicalTrials.gov Identifier: NCT03706079|

|Condition or disease||Intervention/treatment||Phase|
|Asthma||Biological: Tezepelumab Other: Placebo||Phase 3|
Subjects who have not met investigational product discontinuation criteria and have attended the EOT visit in either study D5180C00007 or D5180C00009 will be offered the opportunity to consent for the Multicentre, Double-blind, Randomized, Parallel Group, Placebo Controlled, Phase 3, Safety Extension Study to Evaluate the Safety and Tolerability of Tezepelumab versus placebo in Adults and Adolescents (12 years of age and older) with a history of asthma exacerbations and inadequately controlled severe asthma receiving medium or high dose inhaled corticosteroid (ICS) plus at least one additional asthma controller medication with or without oral corticosteroids
Following treatment, subjects will enter a follow-up phase, determined by the predecessor study they had previously completed. Subjects will not receive IP during the follow-up phase. For subjects who entered the study from study D5180C00007 and did not meet IP Discontinuation criteria, the follow-up phase will extend from week 104 to Week 140. Subjects who entered the study from study D5180C00009 will have their follow-up phase extend to week 116.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||951 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||
Subjects previously randomized in one of the predecessor studies to tezepelumab will be assigned and remain on tezepelumab dosing in the Destination Study.
Subjects randomized to placebo arm in the predecessor studies will be re-randomized in a 1:1 ratio to either tezepelumab or placebo.
Given the randomization scheme of subjects in the predecessor studies, this will give an overall subject distribution of 3:1 (tezepelumab:placebo), assuming a similar number of subjects rollover from each arm in the predecessor studies.

- Exposure adjusted incidence rates of AEs/SAEs [ Time Frame: Baseline (Week 0 in predecessor study) to Week 104 ]Exposure adjusted rates defined as the number of events divided by person-time at risk
- Annualized asthma exacerbation rate (AAER) [ Time Frame: Baseline (Week 0 in predecessor study) to Week 104 ]The annualized exacerbation rate is based on exacerbations reported by the investigator in the eCRF
