Brief Summary

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

The purpose of the study is to determine whether ASP0113 (a CMV deoxyribonucleic acid \[DNA\] vaccine) can be detected in plasma after intramuscular (IM) injections, and to determine whether CMV-seropositive healthy volunteers, CMV-seronegative healthy volunteers, CMV-seronegative dialysis patients mount an immune response to the CMV proteins produced by the vaccine after repeated ASP0113 IM injection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Part 1 is open-label with no randomization, and Part 2 is single-blind and randomized. The purpose of Part 1 is to obtain pilot pharmacokinetic data so as to optimize pharmacokinetic sample collection times in Part 2.
