  Purpose

RATIONALE: ONTAK may be able to help reduce the type of cells that prevent other types of immune cells from attacking the breast cancer cells.

PURPOSE: This phase I/II trial is studying the safety of ONTAK and its possible side effects to see how well it works in treating patients with advanced breast cancer that did not respond to previous treatment.

Primary Outcome Measures:
  • Safety and systemic toxicity as assessed by CTCAE v3.0 [ Time Frame: 7 Days after last dose of ONTAK ] [ Designated as safety issue: Yes ]
    Initial evaluation, 3 weeks after cycles 2, 4, and 6

  • Efficacy of ONTAK in depleting T-regulatory cells [ Time Frame: 21 days after cycle 6 ] [ Designated as safety issue: No ]
    Initial evaluation, 3 weeks after cycles 2, 4, and 6


Secondary Outcome Measures:
  • Incidence of interleukin-2 (IL-2) and IL-2 receptor (IL-2R) expression in tumor samples [ Time Frame: 21 days after cycle 6 ] [ Designated as safety issue: No ]
    Initial evaluation, 3 weeks after cycles 2, 4, and 6

  • Presence of circulating sIL-2R in the peripheral blood [ Time Frame: 21 days after cycle 6 ] [ Designated as safety issue: No ]
    Initial Evaluation, 3 weeks after cycle 2, 4, 6

  • Presence of endogenous tumor-specific immunity [ Time Frame: 21 days after cycle 6 ] [ Designated as safety issue: No ]
    Initial Evaluation, 3 weeks after cycle 2, 4, 6

  • Anti-tumor effects of ONTAK determined by tumor response and progression [ Time Frame: 21 days after cycle 6 ] [ Designated as safety issue: No ]
    Initial Evaluation, 3 weeks after cycle 2, 4, 6

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate the safety of ONTAK infusion in patients with advanced refractory breast cancer.

II. To evaluate the effect of ONTAK administration on peripheral blood T-regulatory cells.

SECONDARY OBJECTIVES:

I. To evaluate the incidence of IL-2R expression in tumor samples and investigate the correlation of tumor IL-2R expression and tumor response to ONTAK therapy.

II. To evaluate levels of circulating sIL-2R before and after ONTAK therapy. III. To evaluate the effect of ONTAK on endogenous tumor specific immunity. IV. To evaluate the potential anti-tumor effects of ONTAK in patients with advanced refractory breast cancer.

OUTLINE:

Patients receive ONTAK IV over 1 hour on days 1-5. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 1 year.
