Frequently asked questions about AZD7442

What is AZD7442 used for?

AZD7442 is an investigational monoclonal antibody combination being developed for Coronavirus Disease 2019 (COVID-19), caused by SARS-CoV-2. It is studied for the prevention and treatment of COVID-19, including as pre-exposure prophylaxis in adults. The drug is in Phase 3 clinical development and is not yet approved.

How does AZD7442 work?

AZD7442 is a combination of two monoclonal antibodies, AZD8895 and AZD1061, which target the SARS-CoV-2 spike protein. By binding to the virus, these antibodies are designed to neutralize the virus and prevent it from infecting human cells, potentially providing protection against COVID-19.

Who makes AZD7442?

AZD7442 is developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker AZN. AstraZeneca is conducting clinical trials to evaluate the safety and efficacy of AZD7442 for COVID-19 prevention and treatment.

What phase is AZD7442 in?

AZD7442 is in Phase 3 clinical development. It has completed Phase 1 and Phase 3 trials, including a large Phase 3 study for pre-exposure prophylaxis of COVID-19 in adults. The drug is investigational and has not received FDA approval.

What clinical trials is AZD7442 in?

AZD7442 has been studied in several clinical trials, including NCT04507256 (Phase 1, prevention and treatment), NCT04625725 (Phase 3, pre-exposure prophylaxis), NCT04896541 (Phase 1, Japanese participants), and NCT05166421 (Phase 1, pharmacokinetic comparability). All trials are completed, with total enrollment of 7,338 participants.

Is AZD7442 the same as AZD8895 and AZD1061?

AZD7442 is a combination therapy containing two monoclonal antibodies, AZD8895 and AZD1061. It is being developed as a co-formulation of these two antibodies. A clinical trial (NCT05166421) evaluated the pharmacokinetic comparability of the co-formulation versus the individual antibodies.
