Safety and Efficacy of GX-188E Administered Via EP Plus GX-I7 or Imiquimod.

June 29, 2017 updated by: Jongsup Park, Seoul St. Mary's Hospital

A Randomized, Open-label Study to Evaluate the Safety and Efficacy of GX-188E, a DNA Therapeutic Vaccine Administered Intramuscularly by Electroporation, With GX-I7 Intravaginal Application or Imiquimod Topical Application in HPV16 and/or 18 Positive Patients With CIN3.

This is a study to investigate the safety and efficacy of GX-188E administered IM plus local administration of GX-I7 or Imiquimod at cervix in subjects with cervical intraepithelial neoplasia (CIN) 3.
