Eli Lilly & Co says its combination antibody therapy is effective at treating mild to moderate cases of COVID-19.
The treatment, a mixture of drugs bamlanivimab and etesevimab, was developed by Indianapolis-based Lilly and the Canadian company AbCellera.
It recognizes the virus once a person is infected and attaches to it, preventing the pathogen from entering human cells, and therefore neutralizing it.
In trial data released on Wednesday, Eli Lilly said the combination reduced the risk of hospitalization and death by 87 percent compared to a placebo.
The results are an improvement of an earlier study of the combination, which reduced the risk of hospitalization and death by 70 percent.
