Detailed Description

Phase 2/3, multicenter, double-blind, placebo-controlled, randomized study of the mAb ADG20 in the prevention of symptomatic COVID-19 in adults and adolescents with no known history of SARS-CoV-2 infection but whose circumstances place them at increased risk of acquiring SARS-CoV-2 infection and developing symptomatic COVID-19. This objective was independently evaluated in a cohort of participants with reported recent exposure to an individual diagnosed with a SARS-CoV-2 infection (post-exposure prophylaxis) and in a cohort of participants with no reported exposure to SARS-CoV-2 (pre-exposure prophylaxis). These cohorts included participants whose advanced age (≥55 years old) or health status placed them at risk for severe COVID-19 or COVID-19 complications.

    2. Pre-exposure population: Occupational, housing, recreational and/or social conditions that are likely to increase risk of exposure to SARS-CoV-2.
