April 11, 2024 07:00 AM Eastern Daylight Time--WILMINGTON, Del.--(BUSINESS WIRE)--AstraZeneca’s FASENRA® (benralizumab) is now approved by the US Food and Drug Administration (FDA) for add-on maintenance treatment for patients with severe asthma aged 6 to 11 with an eosinophilic phenotype.1 FASENRA was first approved in 2017 as an add-on maintenance for the treatment of severe eosinophilic asthma (SEA) in patients aged 12 and older.1
This additional indication for FASENRA was supported by evidence from TATE, an open-label, multinational, non-randomized, parallel assignment Phase III trial, as well as adequate and well-controlled trials in adult and adolescent populations.2 In the TATE study, FASENRA met the primary endpoints, demonstrating pharmacokinetics (PK) and pharmacodynamics (PD) in children aged 6 to 11 years old with SEA were consistent with those seen in prior trials. The safety and tolerability of FASENRA in the trial was also consistent with the known profile of the medicine.2 The recommended dose for FASENRA is 30 mg for patients 6 years and older who weigh 35 kg or more. For patients aged 6 to 11 who weigh less than 35 kg, a new 10 mg dose will be available.1 FASENRA is administered by subcutaneous injection every 4 weeks for the first 3 doses, and then every 8 weeks.
Lynda Mitchell, MA, CAE, CEO, of the Allergy & Asthma Network, said: “We welcome additional treatment options for children living with severe asthma, a condition that remains complicated to manage, further helping to address the unmet need in this patient population and reducing the burden of disease for the broader asthma community.”
Asthma is the most common chronic childhood disease and can cause serious symptoms such as coughing, wheezing and difficulty breathing.3 Children with severe asthma and their families face a significant burden, including impaired school performance, substantially higher healthcare resource use and a poorer quality of life.4 Severe asthma is a debilitating type of asthma that can be complicated and challenging to treat.4
Liz Bodin, Vice President, US Respiratory & Immunology, AstraZeneca said: “We’re proud that FASENRA has helped more than 100,000 patients in the US to date. Expanding options for children whose quality of life has been drastically impacted by severe eosinophilic asthma with the help of FASENRA is an exciting step in our mission to revolutionize asthma care.”
FASENRA is currently approved as an add-on maintenance treatment for patients aged 6 and older with SEA in the US.1
TATE Phase III Trial
TATE was an open-label, Phase III trial evaluating the safety of FASENRA in children aged 6 to 11 years with severe eosinophilic asthma. The trial evaluated the PK, PD and safety of FASENRA administered subcutaneously in 28 children in the US and Japan aged 6 to 11 years, in addition to 2 patients aged 12 to 14 years in Japan with severe eosinophilic asthma over 48 weeks.2
FASENRA met the primary endpoints in the trial, demonstrating PK, PD, and safety in children aged 6 to 11 years old with SEA were consistent with those seen in prior trials.
FASENRA
FASENRA is a monoclonal antibody that binds directly to IL-5 receptor alpha on eosinophils and attracts natural killer cells to induce rapid and near-complete depletion of blood and tissue eosinophils in most patients via apoptosis (programmed cell death).5,6
FASENRA (benralizumab) is currently approved in more than 80 countries, including the US, EU, and Japan, and is approved for self-administration in the US, EU and other countries.7-10 FASENRA has been prescribed to over 100,000 patients in the US.11
FASENRA is in development for other diseases including chronic obstructive pulmonary disease, chronic rhinosinusitis with nasal polyps and hypereosinophilic syndrome.12-14
FASENRA was developed by AstraZeneca and is in-licensed from BioWa, Inc., a wholly-owned subsidiary of Kyowa Kirin Co., Ltd., Japan.
AstraZeneca in Respiratory & Immunology
Respiratory & Immunology, part of BioPharmaceuticals, is one of AstraZeneca’s main disease areas and is a key growth driver for the Company.
AstraZeneca is an established leader in respiratory care with a 50-year heritage. The Company aims to transform the treatment of asthma and COPD by focusing on earlier biology-led treatment, eliminating preventable asthma attacks, and removing COPD as a top-three leading cause of death. The Company’s early respiratory research is focused on emerging science involving immune mechanisms, lung damage and abnormal cell-repair processes in disease and neuronal dysfunction.
With common pathways and underlying disease drivers across respiratory and immunology, AstraZeneca is following the science from chronic lung diseases to immunology-driven disease areas. The Company’s growing presence in immunology is focused on five mid- to late-stage franchises with multi-disease potential, in areas including rheumatology (including systemic lupus erythematosus), dermatology, gastroenterology, and systemic eosinophilic-driven diseases. AstraZeneca’s ambition in Respiratory & Immunology is to achieve disease modification and durable remission for millions of patients worldwide.
AstraZeneca
AstraZeneca is a global, science-led biopharmaceutical company that focuses on the discovery, development, and commercialization of prescription medicines in Oncology, Rare Diseases, and BioPharmaceuticals, including Cardiovascular, Renal & Metabolism, and Respiratory & Immunology.
