Evaluation of VGX-3100 and Electroporation Alone or in Combination With Imiquimod for the Treatment of HPV-16 and/or HPV-18 Related Vulvar HSIL (Also Referred as: VIN 2 or VIN 3)

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 high-grade squamous intraepithelial lesion (HSIL) \[vulval intraepithelial neoplasia 2 or 3 (VIN 2 or VIN 3)\] associated with human papilloma virus (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

Official Title
A Phase 2, Randomized, Open Label, Efficacy Study of VGX-3100 Delivered Intramuscularly Followed by Electroporation With CELLECTRA™ 2000 Alone or in Combination With Imiquimod, for the Treatment of HPV-16 and/or HPV-18 Related High Grade Squamous Intraepithelial Lesion (HSIL) of the Vulva
Primary Outcomes
Outcome Description
A treatment responder for the primary endpoint was defined as a participant with no histologic evidence of vulvar HSIL (normal tissue or vulvar low grade squamous intraepithelial lesions (LSIL) \[vulval intraepithelial neoplasia 1 (VIN1)\] or condyloma) and no evidence of HPV-16 or HPV-18 (i.e., elimination of the specific genotypes \[16, 18, or both\]) in vulvar tissue at evaluation and who did not receive any non-study related treatment for vulvar HSIL. All lesions were evaluated for histologic evidence of vulvar HSIL or evidence of HPV-16/18 in vulvar tissue.
Outcome Measure
Percentage of Participants With No Histologic Evidence of Vulvar HSIL and No Evidence of HPV-16 and/or HPV-18 in Vulvar Tissue Samples
Outcome Time Frame
Week 48
Secondary Outcomes
Outcome Description
An adverse event (AE) was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body, or worsening of a pre-existing condition, temporally associated with the use of a product whether or not considered related to the use of the product. A TEAE was defined per protocol as any AE with onset after the administration of study medication through the end of the study (i.e., study discharge).
Outcome Time Frame
7 days following each dose: Day 0 (Days 0 to 7), Week 4 (Days 22 to 28), Week 12 (Days 78 to 84), Week 24 (Days 162 to 168), and Week 52 (Days 358 to 364)
Outcome Measure
Percentage of Participants With at Least One Local and Systemic Treatment-emergent Adverse Event (TEAE) During 7 Days Following Each Dose
Outcome Description
An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body, or worsening of a pre-existing condition, temporally associated with the use of a product whether or not considered related to the use of the product.
Outcome Time Frame
From baseline up to Week 100
Outcome Measure
Percentage of Participants With Adverse Events (AEs)
Outcome Description
Participants with no histologic evidence of vulvar HSIL (normal tissue or vulvar LSIL \[VIN1\] or condyloma) based on histology (i.e. biopsies or excisional treatment) were considered. All lesions were evaluated for histologic evidence of vulvar HSIL.
Outcome Time Frame
Week 48
Outcome Measure
Percentage of Participants With No Histologic Evidence of Vulvar HSIL
Outcome Description
Participants with no evidence of HPV-16 and/or HPV-18 indicated the clearance of the specific HPV genotypes \[16, 18, or both\]. All lesions were evaluated for evidence of HPV-16/18 in vulvar tissue.
Outcome Time Frame
Week 48
Outcome Measure
Percentage of Participants With No Evidence of HPV-16 and/or HPV-18 in Vulvar Tissue Samples

Outcome Description
Lesion(s), defined as areas that stain acetowhite were assessed. Analysis of qualifying lesions was defined as the change in total surface area of only lesions with both baseline and Week 48 measurements. Percent change in the cumulative surface area of the acetowhite vulvar lesion(s) was determined by the quantitative analysis of standardized prebiopsy photographic imaging of qualifying lesion(s) at Week 48 compared to baseline.
Outcome Time Frame
From baseline to Week 48
Outcome Measure
Percent Change From Baseline in the Cumulative Surface Area of the Acetowhite Vulvar Lesion(s)
Outcome Description
Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood samples. Assessment of cellular immune activity was performed by IFN-γ enzyme-linked immunosorbent spot-forming (ELISpot) assay.
Outcome Time Frame

Outcome Time Frame
Weeks 15, 27, 48, 74, and 96
Outcome Measure
Levels of Serum Anti-HPV-16 and Anti-HPV-18 Antibody Concentrations
Outcome Description
Assessment of cellular immune activity was measured using the application of flow cytometry for the purpose of performing a Lytic Granule Loading Assay. The Lytic Granule Loading Assay examines the following external cellular markers: cluster of differentiation 3 (CD3), CD4, CD8 (T-cell identification), CD137, CD38, and CD69 (T-cell activation markers) as well as PD-1 (exhaustion/activation marker). Here, a change from baseline in CD8+/CD137+ PBMCs expressing Perforin+ was reported.
