Study Details

Study Description

Brief Summary

The purpose of this study is to determine the optimal dose of GX-188E for the Phase 3 and access the efficacy and safety of GX-188E according the protocol in patients with Cervical Intraepithelial Neoplasia 3 (CIN3).

Condition or Disease Intervention/Treatment Phase
  • Biological: GX-188E
Phase 2

Detailed Description

Subjects who are eligible for this study are allocated to one of the two treatment groups of GX-188E. All Subject received GX-188E intramuscularly using the electroporator(EP) on alternating deltoid muscles which will be performed totally three times during the study period.
