Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This was an open-label study that evaluated the safety, tolerability, and immunogenicity of dose combinations of INO-1800 (DNA plasmids encoding Hepatitis B surface antigen \[HBsAg\] and Hepatitis B core antigen \[HBcAg\]) and INO-9112 (DNA plasmid encoding human interleukin 12) delivered by electroporation (EP) in 90 (ninety) nucleos(t)ide analogue treated participants.
