This is an interventional treatment trial for ASC-US

Eligibility Criteria

25 Years - 70 Years (Adult, Older Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  1. Female subjects age 25-70 years with confirmation of ASC-US, ASC-H, or LSIL by liquid-based cytology
  2. HIV uninfected
  3. Patients whose cytologic specimen is HPV16+ by Aptima HPV 16 18/45 Genotype Assay
  4. Body Mass Index ≤ 32 kg/m2
  5. Hepatitis B surface antigen negative
  6. Anti-hepatitis C virus antibody (anti-HCV) negative or negative HCV PCR if anti-HCV positive
  7. Patients who are able and willing to comply with all study procedures and voluntarily sign an informed consent form, and with anticipated availability for the planned follow-up period of one year
  8. Patients who are of childbearing potential agree to remain sexually abstinent, use methods of contraception (e.g. oral contraception, barrier methods, spermicide, intrauterine device (IUD)), or have a partner who is sterile (i.e., vasectomy) through 6 months.
  9. Patients must have adequate organ function at the time of enrollment as defined by the following parameters: white blood cell count >3,000/mcL; lymphocyte number >500/mcL; absolute neutrophil count >1,000/mcL; platelets >90,000/mcL; hemoglobin >9 g/dL; total bilirubin <3 X the institutional limit of normal; aspartate aminotransferase (AST [SGOT]) / alanine aminotransferase (ALT [SGPT]) <3 X the institutional limit of normal; creatinine <2.5X the institutional limit of normal.
  10. Histologic diagnosis of <CIN2 upon screening colposcopic examination with mandatory ECC, and cervical biopsy(ies) as clinically indicated.

Exclusion Criteria:

  1. Patients who are attempting pregnancy within 6 months, pregnant, or breastfeeding.
  2. Patients with immunodeficiency, or treatment with immunosuppressive medications
  3. Administration of any blood product within 3 months of enrollment.
  4. Administration of any licensed vaccine within 2 weeks of enrollment (4weeks for measles vaccine)
  5. Participation in a study with an investigational compound or device within 30 days of signing informed consent.
  6. History of seizures (unless seizure free for 5 years)
  7. Patients with positive serological test for human immunodeficiency virus (HIV).
  8. Previous cancer history within the past 5 years.
  9. Patients who have had chemotherapy, radiation, biological cancer therapy, or other investigational agents within 28 days prior to the first dose of study drug.
  10. Patients who have had surgery within 28 days, excluding minor procedures (dental work, skin biopsy, etc).
  11. Patients with an uncontrolled intercurrent illness including, but not limited to, ongoing, or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  12. Patients who have an active autoimmune disease (e.g., rheumatoid arthritis, systemic lupus erythematosus (SLE), ulcerative colitis, Crohn's Disease, multiple sclerosis (MS), ankylosing spondylitis).
  13. Patients with a recognized immunodeficiency disease including cellular immunodeficiencies, hypogammaglobulinemia, or dysgammaglobulinemia; patients who have acquired, hereditary, or congenital immunodeficiencies; patients being chronically treated with immunosuppressive drugs such as cyclosporin, adrenocorticotropic hormone (ACTH), or systemic corticosteroids
  14. Previous cervical conization or LEEP procedure or previous total hysterectomy due to cervical lesions at enrollment.
