A Vaccine (9pNGVL4aCRTE6E7L2 HPV DNA Vaccine) for the Treatment of HPV16 Positive High-Grade Cervical Intraepithelial Lesions
This phase I trial evaluates the best dose and effect of 9pNGVL4aCRTE6E7L2 HPV DNA vaccine in treating patients with HPV16 positive high-grade cervical intraepithelial lesions. 9pNGVL4aCRTE6E7L2 HPV vaccine is made of DNA and is considered as gene therapy. Gene therapy means putting a new gene into some of the cells in the body to treat a disease. 9pNGVL4aCRTE6E7L2 HPV may kill tumor cells by blocking a gene that helps cancer form and grow. Giving 9pNGVL4aCRTE6E7L2 HPV may help the immune system to recognize and attack lesions that have HPV in them.

Exclusion Criteria
- Patients with high-grade cervical intraepithelial lesions (CIN2/3) that are HPV16 negative

- For the HIV+ cohort ONLY: patients with an HIV viral load > 200 cp/mL
- Administration of chronic (defined as more than 14 days) immunosuppressants or other immune-modifying drugs within 6 months of study entry; for corticosteroids, this will mean prednisone, or equivalent, greater than or equal to 0.5 mg/kg/day; inhaled and topical steroids are allowed
- Due to interference with the immunologic measurements and compromising the analysis of the safety of the vaccine, participants with active or chronic infection of hepatitis C virus (HCV) or hepatitis B virus (HBV) are excluded as well as those who have previously received an HPV vaccine (Gardasil or Cervarix or an investigational HPV vaccine)
- Participants who are receiving or have received any other investigational agents within 30 days of registration
- Participants with an uncontrolled intercurrent illness including, but not limited to, ongoing or active systemic infection (yeast, bacterial, or viral), symptomatic congestive heart failure, unstable angina pectoris, unstable cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Participants with a history of autoimmune disease such as systemic lupus erythematosus, celiac disease, autoimmune hepatitis, multiple sclerosis, exclusive of a history of thyroiditis, psoriasis, Sjrogen’s, or inflammatory bowel disease
- Pregnant and breastfeeding women are excluded from this study because pNGVL4aCRTE6E7L2 is a vaccine with unknown potential for teratogenic or abortifacient effects
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to pNGVL4aCRTE6E7L2 DNA vaccine
- Participants with a metal implant(s) at the site of injection or any electronic stimulation device, such as cardiac demand pacemakers, automatic implantable cardiac defibrillator, nerve stimulators, or deep brain stimulators

- Individuals in whom the ability to observe possible local reactions at the eligible injection sites (deltoid region) is, in the opinion of the investigator, unacceptably obscured due to a physical condition or permanent body art
- Acute or chronic, clinically significant hematologic, pulmonary, cardiovascular, or hepatic or renal functional abnormality as determined by the investigator based on medical history, physical examination, previous electrocardiogram (EKG), and/or laboratory screening test
- History of prior malignancy < 5 years; however individuals with completely resected basal cell or squamous cell carcinoma of the skin within this interval may be enrolled
- Inability to understand or unwillingness to sign an informed consent document

Determine the safety and tolerability of pNGVL4aCRTE6E7L2 deoxyribonucleic acid (DNA) vaccine, as administered by intermuscular (IM) injection with TriGrid electroporation to human immunodeficiency virus (HIV)- adult female subjects (>= 19 years), with biopsy confirmed cervical intraepithelial (CIN) II or III that is human papillomavirus (HPV)16+.
II. Determine the safety and tolerability of pNGVL4aCRTE6E7L2 DNA vaccine, as administered by intermuscular (IM) injection with TriGrid electroporation to HIV+ adult female subjects (>= 19 years), with biopsy confirmed cervical intraepithelial (CIN) II or III that is HPV16+.
III. To determine the appropriate dose of pNGVL4aCRTE6E7L2 DNA vaccine using the Intramuscular TriGrid Delivery System for HIV- and HIV+ patients as determined by toxicity and immunogenicity for a subsequent phase II clinical trial.
SECONDARY OBJECTIVES:
I. Assess the impact of vaccination upon the grade of CIN, measured by reduction to < CIN2.
II. Assess the impact of vaccination/delivery system upon cytologic grade, measured by reduction to < high grade squamous intraepithelial neoplasia (HSIL).
III. Assess the impact of vaccination upon HPV16 viral DNA detection in cervical cytology specimens, measured by conversion to HPV16 negativity.
EXPLORATORY OBJECTIVES:
I. Evaluate the levels of circulating HPV16 E6/E7-specific CD8+ T cells and/or CD4+ T cells in the peripheral blood pre- and post-vaccination using enzyme-linked immunosorbent spot (ELISPOT).
II. Evaluate the levels of circulating HPV16 E6/E7-specific CD8+ T cells and/or CD4+ T cells in the peripheral blood pre- and post-vaccination using intracellular cytokine staining and/or cell surface staining with multi-parameter flow cytometry analysis as well as major histocompatibility complex (MHC) class I tetramer staining.
III. Evaluate pre- and post-vaccination levels and neutralizing titers of circulating antibody to HPV16 E6, E7, and L2 in the peripheral blood by enzyme-linked immunosorbent assay (ELISA) and HPV neutralization assays.
IV. Evaluate the levels of circulating (systemic) HPV16 E6/E7-specific CD8+ T cells in the peripheral blood pre- and post-vaccination using T cell receptor sequencing and HPV antigen functional expansion of specific T cell (FEST) assays.
V. Evaluate the levels of immune cell infiltrates by immunohistochemical staining and ribonucleic acid (RNA) scope to the tissues in biopsies collected pre- and post-vaccination.
VI. Evaluate the presence of HPV16 E6/E7-specific CD8+ T cells in the tissue sections pre- and post-vaccination using T cell receptor sequencing.
OUTLINE: This is a dose-escalation study.
Patients receive pNGVL4aCRTE6E7L2DNA vaccine intramuscularly (IM) using the TriGrid Delivery System (TDS)-IM device on day 1 of weeks 0, 4, and 8 in the absence of disease progression or unacceptable toxicity. Patients also undergo urine and blood sample collection, endocervical brushing and colposcopy throughout the study. Additionally, patients undergo cervical biopsy at baseline and loop electrosurgical excision procedure (LEEP) or conization at 6 months.
After completion of study treatment, patients are followed up at 12 weeks and then at 6, 12, and 24 months.
