Vaccine Therapy and QS21 in Treating Patients With Metastatic Breast Cancer

November 16, 2020 updated by: Memorial Sloan Kettering Cancer Center

Pilot Study of Immunization of High Risk Breast Cancer Patients With a Sialyl Lewisª -Keyhole Limpet Hemocyanin Conjugate Plus the Immunological Adjuvant QS-21

RATIONALE: Vaccines may help the body build an effective immune response to kill tumor cells. Giving vaccine therapy together with QS21 may cause a stronger immune response and kill more tumor cells.

PURPOSE: This clinical trial is studying the side effects and how well giving vaccine therapy together with QS21 works in treating patients with metastatic breast cancer.

Detailed Description

OBJECTIVES:

Primary

  • Determine the safety of sialyl Lewisª -keyhole limpet hemocyanin conjugate vaccine and QS21 immunoadjuvant in patients with metastatic breast cancer.
  • Determine the IgG and IgM antibody response to this regimen in these patients.
  • Determine the proportion of breast cancer cells expressing this antigen in these patients.

Secondary

  • Monitor the presence of circulating tumor cells prior to, during, and after this regimen in these patients.

OUTLINE: Patients receive sialyl Lewisª -keyhole limpet hemocyanin conjugate vaccine subcutaneously (SC) and QS21 immunoadjuvant SC once in weeks 1, 2, 3, 7, and 19 in the absence of disease progression or unacceptable disease.

Blood samples are collected periodically and evaluated for circulating tumor cells and reactivity against sialyl Lewisª antigen in ELISA and/or immunoprecipitation-western blot assays.

After completion of study treatment, patients are followed every 3 months.
