Clinical Trial Summary

This is a study designed to evaluate efficacy and safety of Tezepelumab in reducing oral corticosteroid use in adult patients with severe asthma who are receiving oral corticosteroids with or without additional asthma controller medications.


Description:

This is a multicentre, single-arm, phase 3b study designed to evaluate efficacy and safety of reducing daily oral corticosteroid use after initiation of 210 mg dose of Tezepelumab administered subcutaneously in patients with severe asthma receiving high-dose inhaled corticosteroid plus long-acting β2 agonist and oral corticosteroids with or without additional asthma controller medications.

Participants enrolled in current or previous tezepelumab studies will not be included. - Concurrent enrolment in another clinical study involving an IP. - Treatment with systemic immunosuppressive/immunomodulating drugs, except for OCS used in the treatment of asthma/asthma exacerbations, within the last 12 weeks or 5 half-lives (whichever is longer) prior to Visit 1. - History of anaphylaxis or documented immune complex disease (Type III hypersensitivity reactions) following any biologic therapy. - Positive hepatitis B surface antigen, or hepatitis C virus antibody serology at screening, or a positive medical history for hepatitis B or C. - Pregnant, breastfeeding, or lactating women.
