|---|---|
|
Experimental: VGX-3100 + EP

|
Placebo Comparator: Placebo + EP
IM injections with matching placebo followed by EP using the CELLECTRA™-5PSP device on Day 0, Week 4 and Week 12.
|
Biological: Placebo
1 mL of Placebo will be injected IM and delivered by EP using CELLECTRA™-5PSP on Day 0, Week 4 and Week 12. Device: CELLECTRA™-5PSP CELLECTRA™-5PSP is used for EP following IM injection of VGX 3100 or placebo on Day 0, Week 4 and Week 12. |
Primary Outcome Measures :
- Percentage of Baseline Biomarker-Positive Women with No Evidence of Cervical HSIL on Histology Sample and No Evidence of HPV-16 and/or HPV-18 in Cervical Samples at Week 36 [ Time Frame: At Week 36 ]Participants will be evaluated for evidence of cervical HSIL on histology as well as evidence of HPV-16 and/or HPV-18 in cervical samples by type-specific HPV testing at the Week 36 visit.
Secondary Outcome Measures :
- Safety: Number of Baseline Biomarker-Positive Women and all Women with Any Adverse Events (AEs) and Serious Adverse Events (SAEs) Following Investigational Treatment and for the Duration of the Study [ Time Frame: From baseline to Week 40 ]An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. An SAE is any experience that suggested a significant hazard, contraindication, side effect, or precaution, and fulfilled any of the following criteria: fatal (resulted in death), life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was medically significant or required intervention to prevent any of the other outcomes listed here.
- Percentage of Baseline Biomarker-Positive Women and All Women with No Evidence of HPV-16 and/or HPV-18 in Cervical Samples at Week 36 [ Time Frame: At Week 36 ]Participants will be evaluated for evidence of HPV-16 and/or HPV-18 in cervical samples by type-specific HPV testing at the Week 36 visit.
- Percentage of Baseline Biomarker-Positive Women and All Women with No Evidence of Cervical HSIL on Histology Sample at Week 36 [ Time Frame: At Week 36 ]Participants will be evaluated for evidence of cervical HSIL on histology at the Week 36 visit.
- Percentage of Baseline Biomarker-Positive Women and All Women with No Evidence of Low Grade Squamous Intraepithelial Lesion (LSIL) or HSIL at Week 36 [ Time Frame: At Week 36 ]Participants will be evaluated for evidence of cervical LSIL and HSIL (i.e. no evidence of cervical intraepithelial neoplasia grade 1 [CIN1], CIN2 or CIN3) on histology at the Week 36 visit.
- Percentage of All Women with No Evidence of LSIL or HSIL and No Evidence of HPV-16 and/or HPV-18 at Week 36 [ Time Frame: At Week 36 ]Participants will be evaluated for evidence of cervical LSIL and HSIL (i.e. no evidence of CIN1, CIN2 or CIN3) on histology and be evaluated for evidence of HPV-16 and/or HPV-18 in cervical samples by type-specific HPV testing at the Week 36 visit.
- Percentage of Baseline Biomarker-Positive Women and All Women with No Progression of Cervical HSIL to Cervical Carcinoma from Baseline at Week 36 [ Time Frame: At Week 36 ]Participants will be evaluated for progression of cervical HSIL to cervical carcinoma from baseline on histology at the Week 36 visit.
- Percentage of Baseline Biomarker-Positive Women and All Women Who Have Cleared HPV-16 and/or HPV-18 in Non-cervical Anatomic Locations at Week 36 [ Time Frame: Baseline and Week 36 ]Participants will be evaluated for HPV-16 and/or HPV-18 status in specimens from non-cervical anatomic locations (oropharynx, vagina and intra-anal) at the Week 36 Visit.
- Among Baseline Biomarker-Positive Women and All Women Levels of Serum Anti-HPV-16 and Anti-HPV-18 Antibody Concentrations at Weeks 15 and 36 [ Time Frame: At Weeks 15 and 36 ]
- Among Baseline Biomarker-Positive Women and All Women Interferon-gamma Response Magnitudes at Baseline, Weeks 15 and 36 [ Time Frame: At Baseline, Weeks 15 and 36 ]Interferon-gamma response magnitudes will be determined using the ELISpot assay at baseline, Weeks 15 and 36 visits.
- Among Baseline Biomarker-Positive Women and All Women Cellular Immune Response Magnitudes at Baseline and Week 15 [ Time Frame: At Baseline and Week 15 ]Using flow cytometry cellular immune response magnitudes will be determined at the baseline and Week 15 visits.
