Safety and Efficacy of GX-188E DNA Therapeutic Vaccine Administered by Electroporation After Observation
GX-188E
A Prospective, Observational, Open-label, Multi-center, Follow-up Clinical Study to Determine Recurrence of Cervical Intraepithelial Neoplasia and Evaluate the Long-term Safety of GX-188E, a DNA-based Therapeutic Vaccine, Administered Intramuscularly by Electroporation (EP) in Subjects Who Were Diagnosed With HPV(Human Papillomavirus) 16 or 18 Positive Cervical Intraepithelial Neoplasia 3 (CIN 3) and Participated in Phase 2 Trial (GX-188E_CIN3_P2)

Study Arms (1)
Observational group
Subjects in the period less than 24 weeks after the final administration of GX-188E
Interventions
In phase II study, 72 patients were assigned to two dose groups (1mg and 4mg) and were administered three times with GX-188E by electroporation during an entire period of study. After the final administration, the follow-up will be conducted to investigate safety and efficacy aspects.
Eligibility Criteria
The subjects who have completed the DNA vaccine administration of each dosage (1 and 4 mg).
You may qualify if:
- Those who voluntarily signed informed consent form
- The subjects who have participated in phase II trial(GX-188E\_CIN3\_P2)
You may not qualify if:
- The subjects who didn't receive GX-188E DNA vaccine during Phase II trial (GX-188E\_CIN3\_P2)
- The subjects, it is difficult to participate in this study continuously
- Any other ineligible condition at the discretion of the investigator that would be ineligible to participate the study
