• Cervical swabs must test positive for HPV (by Hybrid Capture 2).

• Normal hepatic and renal functions - AST and ALT < 2.5 x ULN and creatinine < 1.5 x ULN, respectively.
• Females of childbearing potential must use one of the following birth control methods during the treatment period and 2 weeks thereafter: oral, implantable, injectable contraceptives; abstinence (celibacy).

Exclusion Criteria:

Patients will be excluded from the study for any of the following preexisting reasons:

• Patients with LSIL (CIN 1) or invasive squamous cell carcinoma (SCC).
• SIL (CIN) involving the endocervix as determined by endocervical curettage, or otherwise not amenable to adequate colposcopic follow-up evaluations, i.e. unsatisfactory colposcopy.
• CIN 3 involving more than two cervical quadrants on colposcopy.
• Patients treated for cervical SIL within the past year.
• Patients with other malignancy (except for non-melanoma skin) within the past 5 years.
• Patients with any active infections (including HIV) other than HPV.
• Patients with known clinically relevant immunological deficiency.
• Concurrent treatment with cytotoxic, radiation, or immuno-stimulative therapy, or with systemic corticosteroids at a dose of > 5 mg/d of prednisone (or its equivalent).
• Participation in another investigational medication trial concurrently or within 30 days, or prior participation in an HPV vaccine trial. Treatment within the last 30 days with a medication that has not received regulatory approval at the time of study entry.
• Concomitant use of topical vaginal medications.
• Significant acute or chronic medical or psychiatric illness that, in the judgment of the Investigator, could compromise subject safety, limit the subject's ability to complete the study, and/or compromise the objectives of the study.
• History of allergy or hypersensitivity to cosmetics, toiletries, or other topical or dermatologic products.
• Pregnant or lactating females who are nursing and will not consent to cease nursing.
