Outcome Measures

Primary Outcomes (2)

  • Number of Participants With First Case of SARS-CoV-2 RT-PCR-positive Symptomatic Illness

    To estimate the efficacy of a single IM dose of AZD7442 compared to placebo for the prevention of COVID-19 prior to Day 183. Planned to be evaluated through Day 183, however, the number of events required for the primary endpoint was achieved 165 days after the study start date which is displayed in the primary efficacy row below. Final analysis is final data from the study based on the pre-planned 183 days of follow up for this endpoint.

    165 Days for primary analysis, 183 days for final analysis

  • AEs, SAEs, MAAEs, and AESIs Post Dose of IMP

    To assess the safety and tolerability of a single IM dose of AZD7442 compared to placebo

    457 Days, Final analysis

Secondary Outcomes (5)

  • The Incidence of Participants Who Have a Post-treatment Response (Negative at Baseline to Positive at Any Time Post-baseline) for SARS-CoV-2 Nucleocapsid Antibodies.

    366 days

  • The Incidence of SARS-CoV-2 RT-PCR-positive Severe or Critical Symptomatic Illness Occurring After Dosing With IMP

    366 Days

  • The Incidence of COVID-19-related Emergency Department Visits Occurring After Dosing With IMP

    366 days

  • Serum AZD7442 Concentrations, PK Parameters if Data Permit.

    457 days

  • Incidence of ADA to AZD7442 in Serum

    457 days

Other Outcomes (1)

  • AEs, SAEs, MAAEs, and AESIs Post Dose of IMP at Time of Primary Efficacy Analysis

    165 Days

Study Arms (5)
