VGX-3100 Delivered Intramuscularly (IM) Followed by Electroporation (EP) for the Treatment of HPV-16 and/or HPV-18 Related Anal or Anal/Peri-Anal, High Grade Squamous Intraepithelial Lesion (HSIL) in Individuals Seronegative for Human Immunodeficiency Virus (HIV)-1/2

July 11, 2023 updated by: Inovio Pharmaceuticals

A Phase 2, Open Label, Study of VGX-3100 Delivered Intramuscularly (IM) Followed by Electroporation (EP) for the Treatment of HPV-16 and/or HPV-18 Related Anal or Anal/Peri-Anal, High Grade Squamous Intraepithelial Lesion (HSIL), (AIN2, AIN3, PAIN2, PAIN3) in Individuals That Are Seronegative for Human Immunodeficiency Virus (HIV)-1/2

This is a phase 2, open-label efficacy study of VGX-3100 administered by intramuscular (IM) injection followed by electroporation (EP) in adult men and women who are human immunodeficiency virus (HIV) negative with histologically confirmed anal or anal/peri-anal high-grade squamous intraepithelial lesion (HSIL) associated with human papilloma virus (HPV)-16 and/or HPV-18. Approximately 24 participants will receive at least 3 doses of VGX-3100.

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
Time Frame
Percentage of Participants With no Histologic Evidence of Anal or Anal/Peri-Anal HSIL and no Evidence of HPV-16/18 at Week 36
Time Frame: Week 36
Week 36

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
Number 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), and Week 40 (Days 274 to 280)
An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can include any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A TEAE is any AE either reported for the first time or worsening of a pre-existing event after the first dose of study drug.

Mean Change From Baseline in Frequency of HPV-16/17 E6/E7-specific CD8+/CD137+ Peripheral Blood Mononuclear Cells (PBMCs) That Were Perforin Positive at Week 15
Time Frame: Baseline and Week 15
PBMCs were isolated from whole blood samples. The assessment of cellular immune activity occurred via the application Flow Cytometry for the purposes of performing a Lytic Granule Loading Assay. The Lytic Granule Loading assay examined cluster of differentiation (CD)8/CD137 cellular markers and Perforin (proteins involved in lytic degranulation and cytotoxic potential) intracellular marker. The frequency was presented as number of perforin-positive CD8 i.e., CD8+/ CD137+ PBMCs cells per million CD8+/ CD137+ PBMCs cells.
