Severe acute respiratory coronavirus 2 is a novel coronavirus that appears to have first emerged in China in November 2019 causing cases of atypical pneumonia. Since then, the COVID-19 pandemic has caused major disruption to healthcare systems with significant socioeconomic impacts. As of 22 December 2020, the virus had spread to all corners of the globe, involving 218 countries/regions with over 78.00 million confirmed cases reported and more than 1.71 million associated deaths. As a response to the ongoing pandemic, AstraZeneca is developing mAbs to the SARS-CoV-2 spike protein. The SARS-CoV-2 spike protein contains the virus's receptor binding domain, which enables the virus to bind to receptors on human cells. By targeting this region of the virus's spike protein, antibodies can block the virus's attachment to human cells, and, therefore, are expected to block infection. AZD7442, a combination of 2 of these mAbs (AZD8895 and AZD1061), is being evaluated for administration to treat or prevent COVID-19. There are currently one ongoing Phase I study and two ongoing Phase III studies with AZD7442, in addition to this treatment study.~Randomization of approximately 40 Japanese participants is planned.
AZD7442 mAbs are being evaluated for administration to prevent or treat COVID-19. This Phase I study will gather important information on the safety and tolerability of AZD7442.
