Zoledronate in Treating Patients With Cervical Intraepithelial Neoplasia 2/3 or 3

November 21, 2017 updated by: University of California, San Francisco

An Exploratory Clinical Trial of Zoledronic Acid in Women With CIN 2/3 or 3

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.

Detailed Description

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Impact of Zoledronic Acid (ZA) on clinical response
Time Frame: 10 weeks from start of treatment
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).
10 weeks from start of treatment
