Hormone Therapy and OGX-011 Before Radical Prostatectomy in Treating Patients With Prostate Cancer - Full Text View

Sponsored by:	National Cancer Institute of Canada

ClinicalTrials.gov Identifier:	NCT00054106

Purpose

RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as flutamide and buserelin may stop the adrenal glands from producing androgens. OGX-011 may help flutamide and buserelin kill more tumor cells by making tumor cells more sensitive to the drugs. Giving flutamide and buserelin with OGX-011 before surgery may shrink the tumor so it can be removed during surgery.

PURPOSE: Phase I trial to study the effectiveness of combining hormone therapy with OGX-011 before radical prostatectomy in treating patients who have prostate cancer.

December 2002

Detailed Description:

OBJECTIVES:

Determine the maximum tolerated dose and recommended phase II dose of OGX-011 (clusterin antisense oligonucleotide) when administered with neoadjuvant hormonal therapy before radical prostatectomy in patients with adenocarcinoma of the prostate.
Determine the toxicity of this regimen in these patients.
Determine the pharmacokinetics of OGX-011 when this regimen is administered in these patients..
Assess the effects of this regimen on pathologic complete response rates in these patients.
Correlate plasma and/or prostate concentrations of OGX-011 with patient response or toxicity measures.

OUTLINE: This is a dose-escalation study of OGX-011.

Patients receive OGX-011 IV over 2 hours on days 1, 3, 5, 8, 15, 22, and 29; oral flutamide three times daily for 4 weeks; and buserelin subcutaneously on day 1.

Cohorts of 3-6 patients (except for 1 patient at starting dose) receive escalating doses of OGX-011 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. The recommended phase II dose is the dose preceding the MTD.

Patients undergo radical prostatectomy and bilateral pelvic lymphadenectomy 1 week after the last dose of neoadjuvant therapy.

Patients are followed at 7 days after surgery and then at 3 months.

PROJECTED ACCRUAL: Approximately 25-33 patients will be accrued for this study.
