The patients in the study were sick with Covid-19, but had not been admitted to the hospital. Eli Lilly said that in a preliminary analysis the antibody combination reduced the amount of virus in nasal swabs of patients after 11 days.
Key data, including the actual viral loads of patients and the makeup of the study population, were not included in the press release.
In the study, 112 patients received 2.8 grams of each of the antibodies, and 156 received placebo. The difference in viral load was statistically significant at day 11, unlike some doses of Lilly’s single-antibody cocktail. There was also a statistically significant reduction in viral levels three days and seven days after infection.
