About this study

Official title: 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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A study testing QS21, sialyl Lewisª-keyhole limpet hemocyanin conjugate vaccine and immunoenzyme technique in people with Breast Cancer, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2020.
