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

• Patients must have a Hb ≥ 9 g/dl, a peripheral WBC ≥ 3000 mm3 and platelet counts ≥ 100,000 mm3.

• Normal hepatic and renal functions - AST and ALT < 2.5 x ULN and creatinine < 1.5 xULN, respectively.

• Females of childbearing potential must use one of the following birth control methodsduring the treatment period and 2 weeks thereafter: oral, implantable, injectablecontraceptives; abstinence (celibacy).

• 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.

• Concurrent treatment with cytotoxic, radiation, or immuno-stimulative therapy, or withsystemic corticosteroids at a dose of > 5 mg/d of prednisone (or its equivalent).

• Participation in another investigational medication trial concurrently or within 30days, or prior participation in an HPV vaccine trial. Treatment within the last 30days with a medication that has not received regulatory approval at the time of studyentry.

• Concomitant use of topical vaginal medications.

• Significant acute or chronic medical or psychiatric illness that, in the judgment ofthe Investigator, could compromise subject safety, limit the subject's ability tocomplete the study, and/or compromise the objectives of the study.
