  Purpose

This phase II trial is studying how well VEGF Trap works in treating patients with metastatic breast cancer. VEGF Trap may stop the growth of tumor cells by blocking blood flow to the tumor

Primary Outcome Measures:
  • Confirmed tumor response rate defined as the total number of efficacy-evaluable patients who achieved a complete or partial response according to the RECIST criteria [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    A 95% confidence interval for the true response rate will be constructed using the Duffy-Santner approach (Duffy & Santner, 1987).

  • Progression-free survival [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    A 95% confidence interval for the true response rate will be constructed using the Duffy-Santner approach (Duffy & Santner, 1987).


Secondary Outcome Measures:
  • Time to disease progression [ Time Frame: Time from registration to disease progression, assessed up to 5 years ] [ Designated as safety issue: No ]
    Time to event distributions will be estimated using the Kaplan-Meier method (Kaplan & Meier, 1958).

  • Survival time [ Time Frame: Time from registration to death, assessed up to 5 years ] [ Designated as safety issue: No ]
    Time to event distributions will be estimated using the Kaplan-Meier method (Kaplan & Meier, 1958).

  • Duration of response [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
    Median duration of response and the confidence interval for the median duration will be computed.

Detailed Description:

PRIMARY OBJECTIVES:

I. Assess the antitumor activity of VEGF Trap, in terms of tumor response rate, in patients with metastatic breast cancer who have received =< 2 prior chemotherapy regimens for metastatic disease, including a taxane and/or anthracycline.

II. Assess the 6-month progression-free survival rate in patients treated with VEGF Trap.

SECONDARY OBJECTIVES:

I. Describe the adverse event profile (grade using the NCI CTCAE version 3.0) of VEGF Trap in these patients.

II. Describe the progression-free survival times in patients treated with VEGF Trap.

III. Describe the overall survival of patients treated with VEGF Trap. IV. Describe the duration of response in patients treated with VEGF Trap.

OUTLINE: This is a multicenter study.

Patients receive VEGF Trap IV over 1 hour on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3-6 months for up to 5 years.
