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)

August 23, 2023 updated by: Inovio Pharmaceuticals

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

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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With No Histologic Evidence of Vulvar HSIL and No Evidence of HPV-16 and/or HPV-18 in Vulvar Tissue Samples
Time Frame: Week 48
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.
Week 48

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With at Least One Local and Systemic Treatment-emergent Adverse Event (TEAE) During 7 Days Following Each Dose
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)
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).
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)
Percentage of Participants With Adverse Events (AEs)
Time Frame: From baseline up to Week 100
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.
From baseline up to Week 100
Percentage of Participants With No Histologic Evidence of Vulvar HSIL
Time Frame: Week 48
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.
Week 48
Percentage of Participants With No Evidence of HPV-16 and/or HPV-18 in Vulvar Tissue Samples
Time Frame: Week 48

Week 48
Percentage of Participants With No Histologic Evidence of Vulvar HSIL or No Evidence of HPV-16/18 in Vulvar Tissue
Time Frame: Week 48
A treatment responder for the endpoint was defined as a participant with no histologic evidence of vulvar HSIL (normal tissue or LSIL [VIN1] or condyloma) based on histology (i.e. biopsies or excisional treatment) or 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.
Week 48
Percentage of Participants With No Evidence of Vulvar HSIL, No Evidence of Vulvar LSIL (VIN1), and No Evidence of Condyloma on Histology
Time Frame: Week 48
Histologic regression was defined as a participant with no histologic evidence of vulvar HSIL, no evidence of LSIL (VIN1), and no evidence of condyloma. Histologic regression of vulvar HSIL to normal tissue was assessed.
Week 48
Percentage of Participants With No Progression of Vulvar HSIL to Vulvar Cancer
Time Frame: From baseline up to Week 48
Non-progression of vulvar HSIL to vulvar cancer was evaluated from baseline to Week 48. Progression was defined as advancement to carcinoma by histology.
From baseline up to Week 48
Percent Change From Baseline in the Cumulative Surface Area of the Acetowhite Vulvar Lesion(s)
Time Frame: From baseline to Week 48
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.
From baseline to Week 48
Change From Baseline in Interferon-Gamma (IFN-γ) Response Magnitude
Time Frame: Baseline; Weeks 15, 27, 48, 74, and 96
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.
Baseline; Weeks 15, 27, 48, 74, and 96
Levels of Serum Anti-HPV-16 and Anti-HPV-18 Antibody Concentrations
Time Frame: Weeks 15, 27, 48, 74, and 96
A standardized binding enzyme-linked immunosorbent assay (ELISA) was performed to measure the anti-HPV-16/18 antibody response induced by VGX-3100.
Weeks 15, 27, 48, 74, and 96
Change From Baseline in Flow Cytometry Response Magnitude
Time Frame: Baseline; Week 27
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.
Baseline; Week 27
