Study Details

Study Description

Brief Summary

RATIONALE: Monoclonal antibodies such as ABX-EGF can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.

PURPOSE: Phase II trial to study the effectiveness of ABX-EGF in treating patients who have prostate cancer that has not responded to hormone therapy.

Condition or Disease	Intervention/Treatment	Phase
Prostate Cancer	Biological: panitumumab	Phase 2

Detailed Description

OBJECTIVES:

Determine the clinical effect of monoclonal antibody ABX-EGF, determined by the PSA response, in patients with hormone-resistant prostate cancer with rising PSA values without metastasis.
Determine the pharmacokinetics and safety profile (including immunogenicity) of this drug in these patients.
Determine the overall survival of patients treated with this drug.
Determine the time to disease progression and time to PSA progression in patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive monoclonal antibody ABX-EGF IV over 1 hour once weekly. Treatment continues every 8 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years.

PROJECTED ACCRUAL: Approximately 30-50 patients will be accrued for this study.
