Experimental: Parent study Main Cohort - AZD3152 The Main Cohort of the Parent study will enroll approximately 3200 participants. Dosing in the Main Cohort will be staggered, so that it starts with adult participants aged 18 years and older, with no adolescent participants dosed in the Main Cohort until safety data from Visit 2a (Day 8) and Visit 2b (Day 15) have been reviewed by the DSMB for at least 80 adult Main Cohort participants (which will include at least 40 participants who have received AZD3152). Participants in the Main Cohort will be randomized 1:1 to receive AZD3152 300 mg or comparator administered IM in the anterolateral thigh on Day 1. Participants will receive a second dose of their original randomized study intervention (ie, active treatment or comparator) 6 months after Visit 1. | Biological/Vaccine: Placebo (Parent study Sentinel Safety Cohort) single dose of Placebo (3 mL + 2 mL) IM Biological/Vaccine: AZD3152 (Parent study Main Cohort) 300 mg AZD3152 at 150 mg/mL 1 IM injection (thigh) of 2 mL of AZD3152 on Visit 1 Day 1 and on Visit 5 Day 181 |
Active Comparator: Parent study Main Cohort - EVUSHELD™ Participants in the Main Cohort of the Parent study will be randomized 1:1 to receive AZD3152 300 mg or comparator administered IM in the anterolateral thigh on Day 1. Participants will receive a second dose of their original randomized study intervention (ie, active treatment or comparator) 6 months after Visit 1. At the request of regulatory authorities the active comparator will be changed to placebo. As the comparator is given on two occasions, this means that a participant randomized to the comparator arm may receive (a) two doses of EVUSHELD, (b) a dose of EVUSHELD and a dose of placebo, or (c) two doses of placebo. | Biological/Vaccine: EVUSHELD™ (Parent study Main Cohort) 600 mg EVUSHELD™/AZD7442 consisting of 300 mg AZD1061 and 300 mg AZD8895, both at 100 mg/mL 2 IM injections (thigh) of 3 mL each IM on Visit 1 Day 1 and on Visit 5 Day 181 Other Name: EVUSHELD™ |
Placebo Comparator: Parent study Main Cohort - Placebo Participants in the Main Cohort of the Parent study will be randomized 1:1 to receive AZD3152 300 mg or comparator administered IM in the anterolateral thigh on Day 1. Participants will receive a second dose of their original randomized study intervention (ie, active treatment or comparator) 6 months after Visit 1. At the request of regulatory authorities the active comparator will be changed to placebo. As the comparator is given on two occasions, this means that a participant randomized to the comparator arm may receive (a) two doses of EVUSHELD, (b) a dose of EVUSHELD and a dose of placebo, or (c) two doses of placebo. | Biological/Vaccine: Placebo (Parent study Main Cohort) Single doses of 0.9% sodium chloride 2 mL IM for injection on Visit 1 Day 1 and Visit 5 Day 181 |
