Further study details as provided by Benaroya Research Institute:

Primary Outcome Measures:
  • To evaluate the combination of docetaxel and ZD1839 on pathologic complete response (pCR) in radical prostatectomy specimens. Pathological complete response is defined as no microscopic evidence of neoplastic cells in the resected specimen.

Secondary Outcome Measures:
  • Evaluate the toxicity of docetaxel and ZD1839 in patients with high risk, locally advanced prostate carcinoma prior to surgical resection
  • Clinical Response
  • Assessment of margin of positivity at surgical resection
  • Evaluate PSA response from baseline and post treatment

Estimated Enrollment: 29
Study Start Date: May 2003
Study Completion Date: November 2007
Detailed Description:

It is recognized that there is a subset of patients who are at high risk for progression despite aggressive treatment of localized disease at the time of detection. The critical issue is in addressing micrometastatic disease that has already developed prior to diagnosis. This study utilizes daily doses of ZD1839 and weekly docetaxel for two cycles prior to radical prostatectomy.

ZD1839 has demonstrated antiproliferative activity against human tumor xenografts and in coadministration with cytotoxic agents against prostate cell lines (PC-3 and TSU-PRI). The combination of ZD1839 and docetaxel has been reported to be feasible with an acceptable toxicity profile.

This phase II, single center trial is specifically targeting those patients with high-risk adenosarcoma of the prostate.
