NCT03180684

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

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With No Histologic Evidence of Vulvar HSIL and No Evidence of HPV-16 and/or HPV-18 in Vulvar Tissue Samples

    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 Outcomes (11)

  • Percentage of Participants With at Least One Local and Systemic Treatment-emergent Adverse Event (TEAE) During 7 Days Following Each Dose

    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)

    From baseline up to Week 100

  • Percentage of Participants With No Histologic Evidence of Vulvar HSIL

    Week 48

  • Percentage of Participants With No Evidence of HPV-16 and/or HPV-18 in Vulvar Tissue Samples

    Week 48

  • Percentage of Participants With No Histologic Evidence of Vulvar HSIL or No Evidence of HPV-16/18 in Vulvar Tissue

Study Arms (2)

VGX-3100 + EP

EXPERIMENTAL

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.

Biological: VGX-3100Device: CELLECTRA™ 2000

VGX-3100 + EP + Imiquimod

EXPERIMENTAL

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. In addition, participants applied imiquimod 5% cream to the vulvar lesion three times per week for 20 weeks.
