University of California, San Francisco12 enrolled

Overview

RATIONALE: Chemoprevention is the use of certain drugs to keep tumors from forming, growing, or coming back. Zoledronate may prevent the growth of cervical cancer by blocking blood flow to cervical intraepithelial neoplasia cells. The use of zoledronate may keep cancer from forming. PURPOSE: This randomized is studying how well zoledronate works in treating patients with cervical intraepithelial neoplasia 2/3 or 3.

OBJECTIVES: * Assess clinical response, in terms of lesion size and histological grade, of oledronate in patients with cervical intraepithelial neoplasia 2/3 or 3. OUTLINE: This is a randomized, placebo-controlled, double-blind, pilot study. Patients are stratified according to degree of cervical intraepithelial neoplasia (CIN) (CIN2/3 vs CIN3). Patients are randomized to 1 of 2 treatment arms. * Zoledronate: 100 cc of saline with 4 mg of Zoledronate intravenous (IV), over 20 minutes, for 3 doses one week apart * Placebo: 100 cc of saline (IV), over 20 minutes, for 3 doses one week apart In both arms, treatment repeats every 21 days for up to 3 courses. In week 8, patients undergo surgical resection comprising loop excision or cone biopsy. After completion of study treatment, patients are followed at week 10 by telephone. PROJECTED ACCRUAL: A total of 44 patients will be accrued for this study.

Outcomes

Primary Outcomes

Impact of Zoledronic Acid (ZA) on clinical response

The primary objective is to determine whether Zoledronic Acid (ZA), when given to women with CIN 2/3 or 3 for two months prior to surgical excision, has a measurable impact on clinical response (lesion size and histological grade).

Time frame: 10 weeks from start of treatment
