Study start date: April 1, 2004Actual date on which the first participant was enrolled.

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.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
116 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation
: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

None (Single-arm trial)
: If the study has only one group, all participants receive the same treatment, and no allocation is needed.
