Trial summary

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and paclitaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Read more about this study

About this study

Official title: 1) Adenovirus p53 Infected DC Vaccine For Breast Cancer, 2) Translation of Biotechnology Into the Clinic

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and paclitaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Giving vaccine therapy before and/or after chemotherapy and radiation therapy may cause a stronger immune response.

PURPOSE: This randomized phase I/II trial is studying the side effects of two regimens of vaccine therapy and to see how well they work in treating women who are receiving neoadjuvant or adjuvant chemotherapy and adjuvant radiation therapy for stage III breast cancer that overexpresses p53.

Read the detailed description

OBJECTIVES:

  • Determine the safety and toxicity of two different schedules of vaccination comprising p53-infected autologous dendritic cells in women with p53-overexpressing stage III breast cancer undergoing neoadjuvant or adjuvant chemotherapy and adjuvant radiotherapy.
  • Determine the immune response, in terms of humoral and cellular response, in patients treated with these regimens.
  • Determine antigen-specific immune responses in patients treated with these regimens.

OUTLINE: This is a randomized, open-label study. Patients are randomized to 1 of 2 treatment arms.

All patients undergo apheresis for the collection of peripheral blood monocytes that are cultured with interleukin-4 and sargramostim (GM-CSF) to produce dendritic cells. The dendritic cells are infected with a recombinant adenoviral vector containing the wild-type p53 gene.

Patients receive doxorubicin IV and cyclophosphamide IV every 2 weeks for 8 weeks (4 courses) followed 2 weeks later by paclitaxel IV every 2 weeks for 8 weeks (4 courses). Patients with stage III disease then undergo surgery. Three weeks after completion of paclitaxel (or after surgery for patients with stage III disease), patients undergo radiotherapy once daily for 6.5 weeks. Patients are then receive vaccine therapy as per the arm to which they were randomized.

  • Arm I: Patients receive vaccination comprising p53-infected autologous dendritic cells subcutaneously (SC) 1 week after completion of doxorubicin and cyclophosphamide, 1 week after completion of paclitaxel (or after surgery for patients with stage III disease), and at 6 and 12 weeks after completion of radiotherapy (for a total of 4 vaccinations).
  • Arm II: Patients receive vaccination comprising p53-infected autologous dendritic cells SC at 6, 8, 10, and 12 weeks after completion of radiotherapy.

Treatment in both arms continues in the absence of unacceptable toxicity.

Patients are followed at 1 month, every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 20-50 patients (10-25 per treatment arm) will be accrued for this study within 2 years.

What is being measured

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

  1. Number of Participants Who Experienced Toxicity to the Vaccine

    This outcome measure looks at the safety of the vaccine by documenting the number of grade 2, 3, or toxicities experienced by participants related to the vaccine.

    Measured: 1 week after each vaccine dose.

  2. Percent of Patients With an Immune Response to p53-infected Autologous Dendritic Cells

    Measured: Through study completion, an average of 18 months

  3. Peak Immune Response as Measured by Number of Spots Per Cells

    This outcome measure examined the importance of vaccine timing on antigen-specific relative to the primary cytotoxic therapy on the augmentation of antigen specific immune responses by measuring the duration of immune responses of participants

    Measured: 6 months after last immunization

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing autologous dendritic cell-adenovirus p53 vaccine in people with Breast Cancer, run by University of Nebraska 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 14 inclusion and 5 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 22 Sep 2023. 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 combined 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.

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?

Yes. Results are posted in the registry (first posted 12 Dec 2018). 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?

Number of Participants Who Experienced Toxicity to the Vaccine (time frame: 1 week after each vaccine dose.). The study lists 3 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 22 Sep 2023.
