AZD3152, a single mAb, is being developed to have broad neutralizing activity acrossknown SARS-CoV-2 variants of concern for pre-exposure prophylaxis of COVID-19.The aim of the Phase II study is to evaluate the safety, neutralizing activity andefficacy of AZD3152 for pre exposure prophylaxis of COVID-19
Phase II study to assess the safety, neutralizing activity and efficacy of one dose of
AZD3152 compared with one dose of placebo in adults with immunocompromised conditions,
including comorbidities contributing to weakened immunity, thereby increasing the risk of
COVID-19 progression up to severe grade.
