Investigators
The overall officials registered on this study. Names that resolve to a findmyKOL profile link to it; the rest are shown as registered.
- Sei Won Lee, M.D. Ph.D.

Principal Investigator
A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.
Sites
1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

Seoul, South Korea
Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
