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.

Full Title of Study: “A Prospective Phase II Study of Preoperative, Controlled Exisulind Therapy Initiated Prior to Radical Prostatectomy: Effect on Apoptosis”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Non-Randomized
    • Primary Purpose: Treatment

Detailed Description



- 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.

Clinical Trial Outcome Measures

Primary Measures

  • Apoptosis 4 weeks after completion of study as assessed by marker analysis (bcl-2, Bax, Par-4, M30, TUNEL assay, PTEN)

Secondary Measures

  • Modulation of other surrogate endpoint biomarkers (prostate-specific antigen high-grade prostatic intraepithelial neoplasia, MIB-1, and DNA ploidy)
