About
AZD3152, a single mAb, is being developed to have broad neutralizing activity across known SARS-CoV-2 variants of concern for pre-exposure prophylaxis of COVID-19.
The aim of the Phase I/III study (Parent Study) will be to evaluate the safety, efficacy and neutralizing activity of AZD3152 compared with comparator for pre exposure prophylaxis of COVID-19, and separately evaluate the safety and PK of AZD5156, a combination of AZD3152 and AZD1061.
Sub-study:
This Phase II sub-study of SUPERNOVA will assess the safety, PK, and predicted neutralizing activity of AZD3152 compared with EVUSHELD for pre-exposure prophylaxis of COVID-19.
Full description
In the Parent study, the Phase I Sentinel Safety Cohort will assess the safety of AZD5156 (a combination of 2 mAbs, AZD1061 [cilgavimab, a component of AZD7442 (EVUSHELD)] and AZD3152) in healthy adults and the Phase III Main Cohort will assess the safety, efficacy, PK, and neutralizing activity of two doses of AZD3152 compared with two doses of comparator given at a 6-month interval in adults and adolescents 12 years of age or older (weighing at least 40 kg) with conditions causing immune impairment, who are less likely to mount an adequate protective immune response after vaccination and thus are at higher risk of developing severe COVID-19 in 18 countries.
Sub-study:
This Phase II sub-study of SUPERNOVA is operating in USA only, and it will assess the safety, PK, and predicted neutralizing activity of AZD3152 in adults 18 years of age or older (weighing at least 40 kg) with conditions causing immune impairment who are less likely to mount an adequate protective immune response after vaccination as well as individuals who are immunocompetent (including healthy participants) with all degrees of SARS-CoV-2 infection risk.
