Neoadjuvant Docetaxel on Newly Diagnosed Intermediate and High Grade Cancer of the Prostate (2007-5904)
Phase II Study to Determine the Effects of Neoadjuvant Docetaxel on Newly Diagnosed Intermediate and High Grade Cancer of the Prostate in Patients Who Are Scheduled for Radical Prostatectomy With Genomic Correlates of Pathological Response

Detailed Description
PRIMARY OBJECTIVES:
I. To determine the rate of a 3-month prostate-specific antigen (PSA) decline of at least 30% by chemotherapy regimen of docetaxel and prednisone in patients with stage I/II prostate cancer, who are scheduled for prostatectomy.
II. To compare tumor, pathological and PSA responses to neoadjuvant docetaxel between patients with intermediate and high grades of prostate cancer.
III. To obtain prostate specimens for genomic correlates with responses of the chemotherapy regimen of docetaxel and prednisone.
OUTLINE:
Patients receive docetaxel intravenously (IV) over 60 minutes on days 1 and 2 and prednisone orally (PO) twice daily (BID) on days 1-21. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity. Patients undergo prostatectomy within 3 weeks after completion of chemotherapy.
After completion of study treatment, patients are followed up within 7 days.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
PSA response rate (partial response (PR) + complete response (CR))
Time Frame: 9 weeks
|
Expressed with two-sided exact binomial confidence intervals.
Significance of changes between pre- and after-treatment PSA or testosterone will be determined by the Wilcoxon signed-rank test.
The difference of response rates between different pre-treatment pathological stages or Gleason scores will also be examined by Fisher's exact test.
Associations between PSA response and tumor response, and PSA response and gene expression will also be examined by Fisher's exact test.

9 weeks

---|---|---|
Rates of tumor response
Time Frame: Up to 7 days after completion of study treatment
|
Expressed with two-sided exact binomial confidence intervals.
|
Up to 7 days after completion of study treatment
|
The rate of negative surgical margin
Time Frame: Up to 7 days after completion of study treatment

Up to 7 days after completion of study treatment
|
|
The proportion of patients with pathological down-staging defined as evidence of decreased pathological stage or Gleason score when compared with pretreatment pathological stage
Time Frame: Up to 7 days after completion of study treatment
|
Up to 7 days after completion of study treatment
|
|
Adverse events defined as any untoward medical occurrence in a patient administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment
Time Frame: Up to 28 days after completion of study treatment
|
Severity will be categorized by toxicity grade according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.
