Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are on investigational agents or systemic immunosuppressants, you may not be eligible to participate.

What data supports the effectiveness of the dendritic cell vaccine treatment for breast cancer?

Research shows that dendritic cell vaccines can trigger a strong immune response against breast cancer cells, with studies indicating potential anti-tumor effects and some clinical trials demonstrating positive outcomes in patients.12345

Is the dendritic cell vaccine generally safe for humans?

Dendritic cell vaccines have been tested in over 1,000 patients across various cancer types, and adverse effects were uncommon, mostly mild, and not serious, suggesting they are generally safe for humans.13567

How is the dendritic cell vaccine treatment for breast cancer different from other treatments?

The dendritic cell vaccine for breast cancer is unique because it uses the patient's own immune cells, called dendritic cells, to create a personalized treatment that trains the immune system to attack cancer cells. This approach aims to enhance the body's natural ability to fight cancer, unlike conventional treatments that often involve chemotherapy or radiation, which can have significant side effects.12368

What is the purpose of this trial?

This is a pilot protocol to evaluate the safety, feasibility, and immunogenicity of a personalized breast cancer vaccine based utilizing whole exome sequencing data of a patient's residual breast tumor following neoadjuvant chemotherapy.

Eligibility Criteria

This trial is for individuals with a high-risk type of breast cancer known as TNBC, who have already undergone initial chemotherapy. Participants should be those whose tumors still remain after this treatment and are willing to undergo further procedures to create a personalized vaccine.

Inclusion Criteria

My breast cancer is at stage II-III, mostly not hormone-driven, HER2 negative, and still significant after initial treatment.
Women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
My organs and bone marrow are working well.

Exclusion Criteria

Patients who have a medical issue in the opinion of the treating physician and/or PI that would make them unsuitable for pheresis.
Patients with significant uncontrolled intercurrent illness or autoimmune disease requiring systemic immunosuppressants that would be deemed unsuitable to participate in the study by the Principal Investigator (PI).
My cancer is advanced and cannot be removed by surgery.

Treatment Details

Interventions

  • Dendritic Cell (DC) Vaccine
Trial Overview The study is testing the safety and immune response to a new breast cancer vaccine made from patients' own tumor information. It involves taking white blood cells through leukapheresis (a lab procedure) and using them to create the vaccine.
Participant Groups
1Treatment groups
Experimental Treatment
Group I: Dendritic Cell (DC) VaccineExperimental Treatment2 Interventions
The tumor specimen collected from the primary tumor will undergo whole exome sequencing (WES). The WES data will be analyzed to select up to 20 neoantigens. From this screen up to 10 peptides will be selected to be synthesized for testing and use on the DC pheresis product that will be collected. The ready vaccine product will be cryopreserved and then thawed once the patient is ready to under the vaccination sequence.

Dendritic Cell (DC) Vaccine is already approved in United States, European Union for the following indications:

Findings from Research

An autologous dendritic cell (DC) vaccine developed for breast cancer showed promising in vitro efficacy, eliciting a strong cytotoxic T-lymphocyte response against autologous breast cancer cells in 12 female patients with early-stage disease.
The matured DCs demonstrated significant upregulation of activation markers and produced high levels of the cytokine IL12-p70, indicating their potential effectiveness in stimulating the immune response, and they maintained viability and safety after cryopreservation.
An autologous dendritic cell vaccine polarizes a Th-1 response which is tumoricidal to patient-derived breast cancer cells.Tomasicchio, M., Semple, L., Esmail, A., et al.[2020]
The study involved breast cancer patients who received dendritic cell vaccines made from their own tumor lysates, showing no serious adverse effects and a strong immune response with increased Th1 cytokine secretion and NK cells.
Patients who received the DC vaccine had a significantly longer 3-year progression-free survival rate (76.9%) compared to those who did not receive the vaccine (31.0%), indicating its potential effectiveness in delaying disease progression.
Autologous dendritic cell vaccine for estrogen receptor (ER)/progestin receptor (PR) double-negative breast cancer.Qi, CJ., Ning, YL., Han, YS., et al.[2022]
In a Phase I trial involving 32 patients with metastatic breast and renal cancer, a vaccine created by fusing patients' own tumor cells with dendritic cells was found to be safe, with no significant treatment-related toxicity or signs of autoimmunity.
The vaccination led to immunological responses, including increased T cell activity, and resulted in disease regressions in two breast cancer patients and stabilization in several others, indicating potential efficacy in inducing anti-tumor responses.
