RCT for LY-CoV555 monotherapy and LY-CoV555/LY-CoV016 combination therapy with 592 patients showing lower hospitalization/ER visits with treatment.
For viral load at day 11, a statistically significant reduction was found with combination therapy but not monotherapy.

risk of hospitalization/ER, 70.6% lower, RR 0.29, p = 0.05, treatment 4 of 101 (4.0%), control 7 of 52 (13.5%), LY-CoV555 all dosages.
risk of hospitalization/ER, 79.9% lower, RR 0.20, p = 0.13, treatment 1 of 37 (2.7%), control 7 of 52 (13.5%), LY-CoV555 700mg.
risk of hospitalization/ER, 75.2% lower, RR 0.25, p = 0.25, treatment 1 of 30 (3.3%), control 7 of 52 (13.5%), LY-CoV555 2800mg.
risk of hospitalization/ER, 56.3% lower, RR 0.44, p = 0.31, treatment 2 of 34 (5.9%), control 7 of 52 (13.5%), LY-CoV555 7000mg.
risk of hospitalization/ER, 91.8% lower, RR 0.08, p = 0.04, treatment 0 of 31 (0.0%), control 7 of 52 (13.5%), continuity correction due to zero event (with reciprocal of the contrasting arm), LY-CoV555/LY-CoV016.
Effect extraction follows pre-specified rules prioritizing more serious
outcomes. For an individual study the most serious outcome may have a smaller
number of events and lower statistical signficance, however this provides the
strongest evidence for the most serious outcomes when combining the results of
many trials.
