Study summary

RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Oblimersen may increase the effectiveness of docetaxel by making tumor cells more sensitive to the drug.

PURPOSE: This randomized phase II trial is studying how well giving docetaxel together with oblimersen works compared to docetaxel alone in treating patients with hormone-refractory adenocarcinoma (cancer) of the prostate.

Read the detailed description

OBJECTIVES:

Primary

  • Compare the activity of docetaxel with or without oblimersen, in terms of prostate-specific antigen response, in patients with hormone-refractory adenocarcinoma of the prostate.
  • Compare the toxicity of these regimens in these patients.

Secondary

  • Compare the time to progression in patients treated with these regimens.
  • Compare survival of patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, metastatic disease (M0 vs M1 with non-measurable lesions only vs M1 with measurable lesions), prior estramustine (yes vs no), and prior bisphosphonates (yes vs no). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive docetaxel IV over 1 hour on day 5 and oblimersen IV continuously on days 1-7.
  • Arm II: Patients receive docetaxel IV over 1 hour on day 1. In both arms, treatment repeats every 21 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 8 weeks until progressive disease and then every 16 weeks thereafter.

PROJECTED ACCRUAL: A total of 102 patients (51 per treatment arm) will be accrued for this study.
