The first participants have been dosed in a Phase I trial of AZD7442, a combination of two monoclonal antibodies (mAbs) in development for the prevention and treatment of COVID-19.
The trial will evaluate the safety, tolerability and pharmacokinetics of AZD7442. It will include up to 48 healthy participants in the UK aged 18 to 55 years and is funded by the Defense Advanced Research Projects Agency (DARPA), part of the US Department of Defense, and 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.
“This trial is an important milestone in the development of our monoclonal antibody combination to prevent or treat COVID-19. This combination of antibodies, coupled to our proprietary half-life extension technology, has the potential to improve both the effectiveness and durability of use in addition to reducing the likelihood of viral resistance,” says Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca.
Mimic natural antibodies
Should AZD7442 prove to be tolerated and have a favorable safety profile in the trial, AstraZeneca will progress it into larger late-stage Phase II and Phase III trials to evaluate its efficacy as a potential preventative and treatment approach against COVID-19.
Synthesized in the laboratory, mAbs aim to mimic natural antibodies. The treatment has the potential to be given as a preventative option for people exposed to the virus, and to treat and prevent disease progression in patients already infected by the virus.
