Full Study Name:

A Randomized, Double-Blind, Placebo-Controlled, Phase II Study to Evaluate the Efficacy and Safety of LY3819253 and LY3832479 in Participants With Mild to Moderate COVID-19 Illness (IRB no. 00000837)


The purpose of this study is to evaluate the safety and effectiveness of an investigational drug called LY3819253, alone and in combination with the drug LY3832479, in individuals with mild to moderate COVID-19. The study will also examine the dose of these drugs that should be given. Researchers will compare LY3819253 alone and in combination with LY3832479 to placebo (inactive substance). Participants will have a 1 in 2 chance of receiving either a placebo or LY dose (study drug). Because the COVID-19 pandemic may impact participants’ ability or willingness to attend onsite study visits, mobile health visits will be offered so that study procedures can be conducted at home.
