Neoadjuvant Exisulind in Treating Patients Who Are Undergoing Radical Prostatectomy for Stage II or Stage III Prostate Cancer
RATIONALE: Drugs used in chemotherapy, such as exisulind, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug before surgery may shrink the tumor so that it can be removed.
PURPOSE: This phase II trial is studying how well neoadjuvant exisulind works in treating patients who are undergoing radical prostatectomy for stage II or stage III prostate cancer.
Procedure: conventional surgery
Procedure: neoadjuvant therapy
|Study Design:||Allocation: Non-Randomized
Primary Purpose: Treatment
|Official Title:||A Prospective Phase II Study of Preoperative, Controlled Exisulind Therapy Initiated Prior to Radical Prostatectomy: Effect on Apoptosis|
- Apoptosis 4 weeks after completion of study as assessed by marker analysis (bcl-2, Bax, Par-4, M30, TUNEL assay, PTEN)
- Modulation of other surrogate endpoint biomarkers (prostate-specific antigen high-grade prostatic intraepithelial neoplasia, MIB-1, and DNA ploidy)
|Study Start Date:||August 2003|
|Study Completion Date:||September 2006|
- Compare the effect of neoadjuvant exisulind vs no neoadjuvant treatment on apoptosis in patients with stage II or III prostate cancer undergoing radical prostatectomy.
- Determine the effect of this drug (preoperatively) on surrogate endpoint biomarkers (i.e., prostate-specific antigen, high-grade prostatic intraepithelial neoplasia, MIB-1, and DNA ploidy) in these patients.
OUTLINE: This is a nonrandomized, controlled study. Patients are assigned to 1 of 2 groups based on the treating physician.
- Control group: Patients undergo radical prostatectomy only.
- Treatment group: Patients receive oral exisulind once daily for 4 weeks. Patients then undergo radical prostatectomy.
Patients are followed at 1 month.
PROJECTED ACCRUAL: A total of 130 patients (65 per group) will be accrued for this study within approximately 10-12 months.
