Study Summary

The COMET-TAIL main study evaluated efficacy, safety, and tolerability of IM sotrovimab versus IV sotrovimab in high-risk patients for the treatment of mild/moderate COVID-19. In the safety substudy, the aim was to evaluate the safety and tolerability of sotrovimab across a single ascending dose level and over different infusion times when given for the treatment of mild/moderate COVID-19 to participants at high risk of disease progression Main study was completed successfully. The safety sub-study was discontinued early in the context of evolving variants with increased fold changes in the in vitro half maximal inhibitory concentration (IC50) and uncertainty in the clinical relevance of these changes.

Primary Outcome

Progression of COVID-19 through Day 29 as defined by hospitalization \>24 hours for acute management of illness due to any cause or death. Percentage values are rounded off.
