Safety, Tolerability and Immunogenicity of INO-4700 for MERS-CoV in Healthy Volunteers

Summary

The purpose of this Phase 2a, randomized, blinded, placebo-controlled, multi-center study is to evaluate the safety, tolerability and immunogenicity of INO-4700 administered by intradermal (ID) injection followed by electroporation (EP) using the CELLECTRA™ 2000 device in healthy adult volunteers for Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infection.
