A 52-Week, Open-Label, Multicentre Study to Evaluate the Safety of Tezepelumab in Japanese Adults and Adolescents With Inadequately Controlled Severe Asthma (NOZOMI)
This is an open-label, single arm study designed to evaluate the safety of tezepelumab administered subcutaneously every 4 weeks in Japanese adult and adolescent subjects with inadequately controlled severe asthma.
This is open-label, single arm study designed to evaluate the safety of tezepelumab in adults and adolescents with severe, uncontrolled asthma on medium to high-dose ICS and at least one additional asthma controller medication with or without OCS. Approximately 66 subjects will be dosed in Japan. Subjects will receive tezepelumab administered via subcutaneous injection at the study site, over a 52-week treatment period. The study also includes a post-treatment follow-up period of 12 weeks.

At least one additional maintenance asthma controller medication is required according to standard practice of care and must be documented for at least 3 months.
Documented history of at least 1 asthma exacerbation events within 12 months. ACQ-6 score ≥1.5 at screening or on day of registration.
