A Two-Stage Phase 2 Study Of Dose-Intense 4,4'-Dihydroxybenzophenone-2,4-Dinitrophenyl-Hydrazone (A-007) Topical Gel in the Treatment of High-Grade Squamous Intraepithelial Lesions (HSIL) of the Cervix

Inclusion Criteria:

- 18 years of age or older

- The patient or her authorized representative must sign and date an Ethical Review
Board-approved informed consent document. All aspects of the protocol must be
explained and written informed consent obtained.

- Patients must have histologic proof of CIN 2/3 disease documented within the last 12
weeks. If patient is enrolled using prior local biopsy, local slides and pathology
report must be sent to the central laboratory. Patient may be enrolled into the
study based on local laboratory results of CIN 2/3 and will not be discontinued if
central laboratory results differ.

- Cervical swabs must test positive for high risk HPV (by Hybrid Capture 2). If the
patient tests negative for high risk HPV and has proof of CIN 2/3, the patient should
be retested one additional time for high-risk HPV.

- Patients must have a Hgb ≥ 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 x
ULN, respectively.

- Females of childbearing potential must use one of the following birth control methods
during the study (until performance of the LEEP at month 4): oral, implantable,
injectable contraceptives; abstinence (celibacy). Contraceptive sponges, IUD, vaginal
contraceptive rings, spermacides, sponges, condoms, or partner's vasectomy are not
acceptable methods of birth control.

Exclusion Criteria:

- Patients with CIN 1 or with invasive squamous cell carcinoma (SCC).

- CIN appearing to involve the endocervix, as assessed colposcopically

- CIN 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 who have had a LEEP performed in the past 12 months

- Patients with other malignancy (except non-melanoma skin) within the past 5 years.

- Patients with any chronic, 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 >5 mg/d of prednisone (or its equivalent).

- Participation in another investigational medication trial concurrently or within 30
days, or prior administration of a prophylactic HPV vaccine or 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.

- Investigators, site personnel directly affiliated with this study, and their
