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

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

Known hypersensitivity to benralizumab or excipients.

WARNINGS AND PRECAUTIONS

Hypersensitivity Reactions

Hypersensitivity reactions (e.g., anaphylaxis, angioedema, urticaria, rash) have occurred after administration of FASENRA. These reactions generally occur within hours of administration, but in some instances have a delayed onset (i.e., days). Discontinue in the event of a hypersensitivity reaction.

Acute Asthma Symptoms or Deteriorating Disease

FASENRA should not be used to treat acute asthma symptoms, acute exacerbations, or acute bronchospasm.

Reduction of Corticosteroid Dosage

Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of therapy with FASENRA. Reductions in corticosteroid dose, if appropriate, should be gradual and performed under the direct supervision of a physician. Reduction in corticosteroid dose may be associated with systemic withdrawal symptoms and/or unmask conditions previously suppressed by systemic corticosteroid therapy.

Parasitic (Helminth) Infection

It is unknown if FASENRA will influence a patient’s response against helminth infections. Treat patients with pre-existing helminth infections before initiating therapy with FASENRA. If patients become infected while receiving FASENRA and do not respond to anti-helminth treatment, discontinue FASENRA until infection resolves.

ADVERSE REACTIONS

The most common adverse reactions (incidence ≥ 5%) include headache and pharyngitis.

Injection site reactions (e.g., pain, erythema, pruritus, papule) occurred at a rate of 2.2% in patients treated with FASENRA compared with 1.9% in patients treated with placebo.

USE IN SPECIFIC POPULATIONS

A pregnancy exposure registry monitors pregnancy outcomes in women exposed to FASENRA during pregnancy. To enroll call 1-877-311-8972 or visit www.mothertobaby.org/Fasenra.

The data on pregnancy exposure from the clinical trials are insufficient to inform on drug-associated risk. Monoclonal antibodies such as benralizumab are transported across the placenta during the third trimester of pregnancy; therefore, potential effects on a fetus are likely to be greater during the third trimester of pregnancy.

INDICATION

FASENRA is indicated for the add-on maintenance treatment of patients with severe asthma aged 6 years and older, and with an eosinophilic phenotype.

FASENRA is not indicated for treatment of other eosinophilic conditions

FASENRA is not indicated for the relief of acute bronchospasm or status asthmaticus
