Fasenra is the only respiratory biologic that can be administered at home or in a doctor’s office with eight-week maintenance dosing
AstraZeneca has secured approval from the US Food and Drug Administration (FDA) for its pre-filled and single-use auto-injector called Fasenra Pen.
The approval, which is based on data from the Phase III GRECO trial and the Phase I AMES trial, allows the self-administration of respiratory biologic Fasenra (benralizumab).
The company already secured approval for Fasenra self-administration and Fasenra Pen in the European Union (EU). At present, Fasenra is approved as an add-on maintenance treatment for severe eosinophilic asthma in the US, EU, Japan, and other countries.
Fasenra is a monoclonal antibody, which binds directly to the IL-5 receptor alpha on eosinophils and makes natural killer cells to induce rapid and near-complete depletion of eosinophils through apoptosis.
Developed by AstraZeneca, Fasenra is in-licenced from Japan-based Kyowa Kirin wholly-owned subsidiary BioWa.
Fasenra Pen can be used by patients and caregivers to administer the medicine via two-step process
The healthcare professionals and patients can now use the auto-injector to administer Fasenra outside of a clinical setting.
Fasenra Pen allows patients and caregivers to administer the medicine through a two-step process.
The device features a viewing window and audible clicks at the start and end of the injection to guide patients for a successful administration.
GRECO is a multicentre, open‑label and 28-week trial that evaluated patient or caregiver‑reported functionality, performance and reliability of a pre-filled auto-injector device with a fixed 30mg dose of Fasenra administered subcutaneously (SC) every four weeks in a clinic and in an at‑home setting in 120 adults with severe, uncontrolled asthma.
AMES is a multicentre, randomised, open-label and parallel-group study in healthy people that compared the pharmacokinetic (PK) exposure following single 30mg SC administration of Fasenra by using a pre-filled syringe or pre-filled auto-injector devices.2
According to the company, the safety profile in both studies was similar to earlier trials, with no new or unexpected safety findings.
AstraZeneca biopharmaceuticals R&D executive vice president Mene Pangalos said: “Fasenra is the only respiratory biologic that can be given every eight weeks after the initial loading-dose period.
“Today’s news means we can now offer Fasenra in an even more convenient way, giving US healthcare providers and patients the option of administering Fasenra at home or in a doctor’s office, and making treatment more accessible to patients with severe eosinophilic asthma.”
In December 2018, Precision oncology firm Guardant Health entered into a multi-year agreement with AstraZeneca to develop companion diagnostic (CDx) tests for the pharmaceutical company’s oncology products.
