Brief Summary:
The purpose of this study is to test the safety and efficacy of an investigational immunotherapy VGX-3100, in combination with a study device, to treat women with vulvar HSIL (VIN 2 or VIN 3) associated with HPV types 16 and/or 18. VGX-3100 is being assessed as an alternative to surgery with the potential to clear the underlying HPV infection. For more information visit our study website at: www.VINresearchstudy.com

Drug Information available for: Imiquimod

Arm Intervention/treatment
Experimental: VGX-3100 + EP
Intramuscular (IM) injections with VGX-3100 followed by EP using the CELLECTRA™ 2000 device on Day 0, Week 4, Week 12 and Week 24.
Biological: VGX-3100
One milliliter (1 mL) VGX-3100 will be injected IM and delivered by EP using CELLECTRA™ 2000 on Day 0, Week 4, Week 12 and Week 24. A fifth dose and sixth dose of six mg VGX-3100 may be administered IM with EP per the judgment of the Investigator.

Device: CELLECTRA™ 2000
IM injection of VGX-3100 is followed by EP with the CELLECTRA™ 2000 device.

Experimental: VGX-3100 + EP + Imiquimod
IM injections with VGX-3100 followed by EP using the CELLECTRA™ 2000 device on Day 0, Week 4, Week 12 and Week 24. In addition, participants will apply imiquimod 5% cream to the vulvar lesion three times per week for 20 weeks.
Biological: VGX-3100
