Trial Outcomes & Findings for 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) (NCT NCT03180684)

NCT ID: NCT03180684

Last Updated: 2023-08-25

Results Overview

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.

VGX-3100 + EP
Participants with histologically confirmed vulvar high-grade squamous intraepithelial lesion (HSIL) associated with human papilloma virus (HPV) 16 and/or 18, received four doses of 6 mg VGX-3100 as an intramuscular (IM) injection on Day 0, Week 4, Week 12, and Week 24 followed by electroporation (EP) using the CELLECTRA™ 2000 device. Participants with vulvar HSIL who had a reduction in lesion size or no increase in lesion size at Week 48, received a fifth dose of VGX-3100 at Week 52.

Population: mITT population included all participants who received at least 1 dose of VGX-3100 + EP (with or without imiquimod) and had an analysis endpoint of interest. 'Overall number of participants analyzed' indicates the number of participants with data available for outcome measure analysis.

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.

Population: Safety population included all participants who received at least one (1) dose of VGX-3100 (with or without EP).

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).

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.

SECONDARY outcome

Timeframe: Weeks 15, 27, 48, 74, and 96

Population: mITT population included all participants who received at least 1 dose of VGX-3100 + EP (with or without imiquimod) and had an analysis endpoint of interest. 'Overall number of participants analyzed' indicates the number of participants with data available for outcome measure analysis. 'Number analyzed' indicates the number of participants available for analysis at individual time points.

A standardized binding enzyme-linked immunosorbent assay (ELISA) was performed to measure the anti-HPV-16/18 antibody response induced by VGX-3100.

Participants with histologically confirmed vulvar HSIL associated with HPV-16 and/or 18, received four doses of 6 mg VGX-3100 as an IM injection on Day 0, Week 4, Week 12, and Week 24 followed by EP using the CELLECTRA™ 2000 device. Participants with vulvar HSIL who had a reduction in lesion size or no increase in lesion size at Week 48, received a fifth dose of VGX-3100 at Week 52.

Participants with vulvar HSIL who had a reduction in lesion size or no increase in lesion size at Week 48, received a fifth dose of VGX-3100 at Week 52. In addition, participants applied imiquimod 5% cream to the vulvar lesion three times per week for 20 weeks.

SECONDARY outcome

Timeframe: Baseline; Week 27

Population: mITT population included all participants who received at least 1 dose of VGX-3100 + EP (with or without imiquimod) and had an analysis endpoint of interest. 'Overall number of participants analyzed' indicates the number of participants with data available for outcome measure analysis.

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.
