AstraZeneca to supply the US with up to half a million additional doses of the potential COVID-19 antibody treatment AZD7442

AstraZeneca has modified an existing agreement with the US Government to supply up to 500,000 additional doses of AZD7442, a long-acting antibody (LAAB) combination which is in late-stage development for the prevention and treatment of COVID-19.

Today’s agreement with the Department of Health and Human Services (HHS) and the Department of Defense (DoD) builds on an agreement from October 2020 for the support of the late-stage development of AZD7442 and for the supply of an initial 100,000 doses of the LAAB combination. It included the option to acquire additional doses in 2021. The Company also has a separate agreement to supply the DoD with 100,000 doses, bringing potential US supplies of AZD7442 to 700,000 in 2021.

Pascal Soriot, Chief Executive Officer, said: “The long-acting antibody combination has the potential to offer almost immediate protection to those who are not able to be vaccinated, to both prevent infection or treat the disease in patients already infected with the virus. The US Government’s support is critical in helping accelerate the development of AZD7442, which we believe will be an important tool in the fight against COVID-19.”

AZD7442 is currently being evaluated for the prevention and treatment of COVID-19 in late-stage trials in more than 9,000 participants around the world. The two-LAAB combination has been engineered with AstraZeneca’s proprietary half-life extension technology which triples the durability of its action compared to conventional antibodies. The combination of LAABs is also designed to reduce the risk of resistance developed by the SARS-CoV-2 virus and its variants.

Financial considerations
The value of the extended agreement is $205m and is contingent on AZD7442 receiving Food and Drug Administration Emergency Use Authorisation in post-exposure prophylaxis – the ability to prevent COVID-19 in people who have confirmed exposure to the SARS-CoV-2 virus. The Biomedical Advanced Research and Development Authority (BARDA), which is part of the HHS office of the Assistant Secretary for Preparedness and Response, worked with the DoD Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) and the Army Contracting Command to provide funding to purchase the additional doses. Together, the total value of current agreements with the US Government for the development and supply of AZD7442 in 2021 is about $726m. The extended agreement is not anticipated to impact the Company’s financial guidance for 2021.
