RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Androgens can cause the growth of prostate cancer cells. Drugs, such as goserelin, leuprolide, flutamide, or bicalutamide, may stop the adrenal glands from making androgens. Giving bortezomib with hormone therapy may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving bortezomib with or without hormone therapy works in treating patients with relapsed prostate cancer.

Further study details as provided by Medical University of South Carolina:

Primary Outcome Measures:
  • Prostate-specific antigen (PSA) response as measured by complete or partial response, stable or progressive disease 3 months after initial treatment
  • Time to PSA relapse as measured by lab tests 3 months after initial treatment

Secondary Outcome Measures:
  • Safety as assessed by Common Toxicity Criteria, medical history, physical exams, and lab values weekly after combined treatment
  • Disease-free interval assessed 3 months after combined treatment

Estimated Enrollment: 42
Study Start Date: October 2004
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Detailed Description:



  • Determine the prostate-specific antigen (PSA) relapse after an observed rise in testosterone after combination treatment with hormone blockade and bortezomib.


  • Determine the safety of this drug in combination with combined androgen blockade therapy in these patients.
  • Determine the disease-free interval in patients treated with this regimen.
  • Determine time to tsetosterone rise in patients treated wtih this regimen.

OUTLINE: This is an open-label, multicenter study.

Patients receive androgen blockade therapy comprising a 3-month subcutaneous injection of goserelin OR leuprolide OR other FDA-approved method of primary androgen suppression AND oral flutamide or bicalutamide once daily for 3 months. Patients also receive bortezomib IV over 3-5 seconds on days 1, 8, and 15. Treatment with bortezomib repeats every 28 days for 3 courses. Patients achieving a CR discontinue treatment and are observed for PSA or metastatic disease recurrence. Patients with a PR or stable disease receive additional combined androgen blockade therapy and 3 additional courses of bortezomib as above. Patients with progressive disease are removed from the study.

Patients are followed every 3 months for up to 5 years.

PROJECTED ACCRUAL: A total of 21-42 patients will be accrued for this study.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No


  • Histologically confirmed adenocarcinoma of the prostate
  • Relapsed disease after definitive local therapy, as documented only by a rise in prostate-specific antigen (PSA)

    • Experienced PSA relapse after definitive local therapy
    • Rising PSA (≥ 1.0 ng/mL after nadir < 1.0 ng/mL)

      • PSA increase of ≥ 0.3 ng/mL (increase occurred between 2 separate measurements taken ≥ 4 weeks apart)
    • The first of these two PSA values must rise above a previously recorded post-therapy nadir value
  • Ineligible for curative therapy
  • No clinical evidence of local recurrence (i.e., palpable induration or mass in the prostatic fossa) other than PSA elevation
  • No evidence of palpable disease in the prostatic bed
  • No metastatic disease (M0)

    • No non-nodal (> N1) metastasis
    • No evidence of osseous metastasis on bone scan within the past 28 days



  • Over 18
