About this study
Official title: Phase Ib Trial of HER2/Neu Peptide (E75) Vaccine in Breast Cancer Patients at Risk for Recurrence After Surgical and Medical Therapies
The purposes of this study are the following:
- To assess safety and document local and systemic toxicity to the peptide vaccine (E75)
- To determine maximum tolerated dose (MTD) and optimal biologic dose (OBD) for the peptide vaccine
- To evaluate the in vivo cellular immune response to the peptide vaccine
- To evaluate time to recurrence in the vaccinated patients vs. matched controls
Read the detailed description
Breast cancer is the most common malignancy and second most common cause of cancer-specific death among women in the United States. Despite advances in the diagnosis and treatment of breast cancer, one third of the women who develop the disease will die of the disease, accounting for approximately 46,300 deaths/year. While good primary therapies are available to treat early stage breast cancer, there is a substantial failure rate to these therapies in more advanced disease.
Advances in the understanding of the immune response to cancer have lead to the genesis of immunotherapeutic approaches. Specifically, the development of anti-cancer vaccines holds promise as an adjuvant and preventive therapy for patients after both primary surgical and medical treatment for breast cancer, but who are at a high risk for recurrence. Patients with greater than four lymph nodes positive have an 87% chance of recurrence post standard surgical and medical therapies at 10 years. While patients with hormone receptor positive tumors have the option to undergo hormonal therapy, recurrence is especially high among estrogen receptor/progesterone receptor (ER/PR) negative patients. For these patients, currently there is no good treatment option after completion of primary therapy; close surveillance and watchful waiting is the standard.
It is this population of patients that a vaccine strategy to induce cellular immunity would target. We propose to vaccinate these patients with an immunogenic peptide from the HER2/neu protein. If successful, this vaccine strategy could be utilized as an adjuvant to currently accepted first line therapy in future clinical trials.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
E75 + GM-CSF vaccineBiological
Dose escalation scheme involving three patients each receiving injection of 100, 500, or 1,000 mcg E75 + GM-CSF monthly for 6 months. HLA-A2 and HLA-A3 status determined. HLA-A2+ and HLA-A3+ patients receive the vaccine; HLA-A2- and HLA-A3- enrolled to the control arm.
| Study group | Role | What they receive |
|---|---|---|
| E75 + GM-CSF vaccine | Experimental | The dose escalation scheme is for three patients to receive each of the doses, 100, 500, and 1,000 mcg of peptide + 250 mcg GM-CSF each month for 6 months until the maximum tolerated dose is determined. Patients who receive the vaccine are HLA-A2+ and/or HLA-A3+. Responses to the vaccine are measured via immunologic assays. Receives: Biological: E75 + GM-CSF vaccine |
| Control/observation | No intervention | HLA-A2- and HLA-A3- patients do not receive the E37 + GM-CSF vaccine, but are instead enrolled to the control arm for observation. |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary endpoints are the safety and optimal dosing of the vaccine to induce an in vivo peptide-specific immune response.
Measured: Time period needed to determine the maximum tolerated and optimal biologic doses.
Secondary outcomes (1)
The clinical endpoint is time to disease recurrence.
Measured: 30 days after each monthly vaccine, then per standard of care for breast cancer.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing E75 + GM-CSF vaccine in people with Breast Cancer, run by COL George Peoples, MD, FACS at 2 sites 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 6 inclusion and 8 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 31 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
