Two trials of AZD 7442 combination will enrol over 6,000 adults for the prevention of COVID-19 with additional trials enrolling approximately 4,000 adults for the treatment of SARS-CoV-2 infections.- AstraZeneca

AstraZeneca’s long-acting antibody (LAAB) combination, AZD 7442, will advance into two Phase III clinical trials in more than 6,000 participants at sites in and outside the US that are due to begin in the next weeks . The LAABs have been engineered with AstraZeneca’s proprietary half-life extension technology to increase the durability of the therapy for six to 12 months following a single administration. The combination of two LAABs is also designed to reduce the risk of resistance developed by the SARS-CoV-2 virus. The Company has received support of around $486 million from the US Government for the development and supply of AZD 7442 under an agreement with the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the US Department of Health and Human Services, and the Department of Defense Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense. One trial will evaluate the safety and efficacy of AZD 7442 to prevent infection for up to 12 months in approximately 5,000 participants. The second trial will evaluate post-exposure prophylaxis and pre-emptive treatment in approximately 1,100 participants. AstraZeneca is planning additional trials to evaluate AZD 7442 in approximately 4,000 patients for the treatment of COVID-19. AstraZeneca plans to supply up to 100,000 doses starting towards the end of 2020 and the US Government can acquire up to an additional one million doses in 2021 under a separate agreement. LAABs (long-acting antibodies) mimic natural antibodies and have the potential to treat and prevent disease progression in patients already infected with the virus, as well as to be given as a preventative intervention prior to exposure to the virus. A LAAB combination could be complementary to vaccines as a prophylactic agent, e.g. for people for whom a vaccine may not be appropriate or to provide added protection for high-risk populations. It could also be used to treat people who have been infected.
