About this study

Official title: Phase II Study of a HER-2/Neu (HER2) Intracellular Domain (ICD) Peptide-Based Vaccine Administered to Patients With Locally Advanced or Stage IV HER2 Positive Breast Cancer

This phase II trial is studying how well vaccine therapy works in treating patients receiving trastuzumab for HER2-positive stage IIIB- IV breast cancer. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells

Read the detailed description

PRIMARY OBJECTIVES:

  1. To estimate the RFS in patients with HER2 positive locally advanced breast cancer vaccinated with a HER2 ICD peptide-based vaccine.

SECONDARY OBJECTIVES:

  1. To assess the safety of a HER2 ICD peptide-based vaccine administered concurrently with trastuzumab.
  2. To determine the immunogenicity of the HER2 ICD peptide based vaccine when given within one year of initiating standard treatment which includes trastuzumab.
  3. To determine the incidence of the development of T cell immunity specific for the HER2 ICD.
  4. To determine the incidence of the development of intramolecular epitope spreading.
  5. To determine the magnitude of the HER2 ICD specific CD4+ and CD8+ immune response generated with immunization.
  6. To assess whether there is an association between RFS and the development of an immune response (HER2 specific T cell immunity and/or the development of intramolecular epitope spreading).

OUTLINE:

Patients receive HER-2/neu intracellular domain peptide-based vaccine mixed with GM-CSF intradermally (ID) once monthly for 6 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 1, 4, 8, and 12 months and then annually thereafter for up to 5 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relapse-free survival

    Measured: At 4 years

Secondary outcomes (3)
  1. Safety as assessed by NCI CTCAE version 3.0

    Measured: Baseline and 1 month following last vaccination

  2. Immune response as assessed by HER2 specific T cell immunity and/or intramolecular epitope spreading

    Measured: Baseline, midpoint in the immunization schedule (prior to the 4th vaccine), 1 month after the 6th and last immunization and at 4, 8 and 12 months after the end of vaccinations

  3. Correlation of RFS to the generation of an immune response

    Measured: Prior to the 4th vaccine, 1 month after the 6th and last immunization and at 4, 8 and 12 months after the end of vaccinations

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing HER-2/neu intracellular domain protein, leukapheresis and laboratory biomarker analysis in people with HER2-positive Breast Cancer and Male Breast Cancer, run by University of Washington 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?

The sponsor lists 19 inclusion and 7 exclusion criteria. 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 12 Feb 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Relapse-free survival (time frame: At 4 years). 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 12 Feb 2020.
