FDA approves Tezspire™ (tezepelumab-ekko) for severe asthma

December 18, 2021 by Janice Reichert

On December 17, 2021, Amgen announced that the U.S. Food and Drug Administration approved Tezspire™ (tezepelumab-ekko) for the add-on maintenance treatment of adult and pediatric patients aged 12 years and older with severe asthma. Tezepelumab (AMG157, MEDI-9929) is a human IgG2 antibody that targets a cytokine, thymic stromal lymphopoietin, that plays a key role in asthma inflammation. The drug was developed by Amgen in collaboration with AstraZeneca.

The approval was based in part on data from the randomized, placebo-controlled Phase 3 NAVIGATOR study (NCT03347279), which evaluated the effects of tezepelumab in adults and adolescents with severe uncontrolled asthma. In this study, patients received tezepelumab (210 mg; n=529) or placebo (n=532) SC every 4 weeks for 52 weeks. The primary outcome measure of the study, the annualized asthma exacerbation rate from baseline to Week 52, was met. For the tezepelumab group, the annualized rate of asthma exacerbations was 0.93 (95% CI, 0.80 to 1.07), while the rate was 2.10 (95% CI, 1.84 to 2.39) with placebo (rate ratio, 0.44; 95% CI, 0.37 to 0.53; P<0.001). Overall, data from the study indicated that, compared to those administered placebo, patients who received tezepelumab had fewer exacerbations and better lung function, asthma control, and health-related quality of life.104 A pre-specified exploratory analysis showed that tezepelumab reduced the annualized asthma exacerbation rate in patients with nasal polyps by 86% (95% CI: 70, 93) and 52% (95% CI: 42, 61) in those without nasal polyps over 52 weeks compared to placebo given with standard of care.

Marketing applications for Tezspire are under regulatory review in the EU, Japan and several other countries around the world.

Benralizumab granted FDA approval

November 15, 2017 by The Antibody Society

On November 14, 2017, AstraZeneca announced that benralizumab (Fasenra), an afucosylated IgG1 mab targeting the alpha subunit of IL-5R found on eosinophils, received a US Food and Drug Administration approval for the add-on maintenance treatment of patients with severe asthma aged 12 years and older, and with an eosinophilic phenotype. The European Medicines Agency’s Committee for Medicinal Products for Human Use adopted a positive opinion on November 10, 2017, recommending the marketing authorization of benralizumab as an add-on maintenance treatment in adult patients with severe eosinophilic asthma inadequately controlled despite high-dose inhaled corticosteroids plus long-acting b-agonists. The European Commission’s decision regarding marketing authorization in the EU is pending. Marketing applications for benralizumab are undergoing review in Japan and other countries. The mAb was in-licensed from BioWa, Inc., a wholly-owned subsidiary of Kyowa Hakko Kirin Co., Ltd. by MedImmune.

The safety and efficacy of benralizumab as a treatment for asthma were evaluated in the WINDWARD program, which included six Phase 3 trials, SIROCCO, CALIMA, ZONDA, BISE, BORA and GREGALE. The randomized, double-blinded, parallel-group, placebo-controlled SIROCCO (NCT01928771) and CALIMA (NCT01914757) trials evaluated the efficacy and safety of a regular, subcutaneous administration of a fixed 30 mg dose of benralizumab for up to 56 weeks in exacerbation-prone adult and adolescent patients 12 years of age and older. Study results were published in 2016. [1, 2] In the 28-week randomized ZONDA study (NCT02075255), the effects of 30 mg benralizumab administered subcutaneously either every 4 weeks or every 8 weeks (with the first three doses administered every 4 weeks) versus placebo on the reduction in the oral glucocorticoid dose while asthma control was maintained in adult patients with severe asthma. The study’s primary outcome measure, percentage reduction in final oral steroid dose compared with baseline while maintaining asthma control, was met. The median final oral glucocorticoid doses from baseline were reduced by 75% in patients who received either dose of benralizumab,  compared with a reduction of 25% in the oral glucocorticoid doses in the placebo group (P<0.001 for both comparisons).

The Antibody Society maintains a comprehensive table of approved antibody therapeutics and those in regulatory review in the EU or US. As of November 15, 2017, a total of 9 mAbs have been granted first approvals in either the US or EU in 2017, and marketing applications for a total of 10 antibody therapeutics that have not yet been approved in either the EU or US are undergoing review in these regions.

Please log in to access the table, located in the Members Only section.
