Study of Edecesertib in Participants With Cutaneous Lupus Erythematosus (CLE)

About the study

The goal of this clinical study is to test how edecesertib (formerly known as GS-5718) can be useful in treating Cutaneous Lupus Erythematosus (CLE) in participants with CLE. Information on what is happening in the body relating to CLE, how the body processes, is affected by and responds to the study drug, and any study drug side effects will also be collected in this study.
