Severe asthma, biologic hypersensitivity and inefficacy: overcoming treatment barriers with tezepelumab

We present a 30-year-old female with severe T2-high asthma, multiple allergies, and poor disease control despite optimal therapy. She experienced an allergic reaction with omalizumab and dupilumab and had inadequate response to benralizumab. Enrolled in an early access program for tezepelumab, she showed remarkable clinical improvement, with significant FEV1 increase and FeNO reduction, allowing discontinuation of systemic corticosteroids and supplemental oxygen.
