APC8015 and Bevacizumab in Treating Patients With Prostate Cancer

Phase 2

Completed

• Conditions: Prostate Cancer
• Interventions: Biological: bevacizumab; Biological: prostatic acid phosphatase-sargramostim fusion protein; Biological: sipuleucel-T; Biological: therapeutic autologous dendritic cells; Procedure: in vitro-treated peripheral blood stem cell transplantation

• Registration Number: NCT00027599
• Lead Sponsor: National Cancer Institute (NCI)

Brief Summary

Phase II trial to study the effectiveness of APC8015 combined with bevacizumab in treating patients who have undergone radiation therapy and/or surgery and who have progressive prostate cancer. Biological therapies such as APC8015 use different ways to stimulate the immune system and stop cancer cells from growing. Monoclonal antibodies such as bevacizumab can locate tumor cells and kill them without harming normal cells. Combining monoclonal antibody therapy with biological therapy may kill more cancer cells.

Detailed Description

OBJECTIVES:

I. Determine the efficacy of APC8015 (Provenge) and bevacizumab, in terms of decline in prostate-specific antigen (PSA) value and effect on PSA doubling time, in patients with progressive prostate cancer.

II. Determine any immune response in patients treated with this regimen. III. Determine the safety of this regimen in these patients.

OUTLINE:

Autologous dendritic cells (DCs) are harvested and pulsed with prostatic acid phosphatase-sargramostim fusion protein to produce APC8015 (Provenge). Patients receive APC8015 IV over 30 minutes and bevacizumab IV over 30-60 minutes on day 1. Treatment repeats every 14 days for 3 courses. Patients continue to receive bevacizumab alone every 14 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every month.
