Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 3 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • The patient must meet the following eligibility inclusion criteria at the time of PROCUREMENT:
  • Diagnosis of advanced stage* or metastatic HER2-positive cancer (Immunohistochemistry or reverse transcription-polymerase chain reaction (RT-PCR) is used to determine HER2 positivity)
  • Definitions of Malignancies and Advanced Stages:
  • Breast ≥Stage IIIb Colon cancer ≥Stage IIIb Esophageal cancer ≥Stage IIIb Gastric carcinoma ≥Stage IIIb Head and Neck cancer Stage IV Lung cancer ≥Stage IIIb Pancreatic cancer Stage IV Prostate cancer Stage IV

About this study

Official title: Administration of Her2 Chimeric Receptor and TGFbeta Dominant Negative Receptor (DNR) Expressing EBV Specific Lymphocytes for Subjects With Advanced Her2 Positive Malignancy (HERCREEM)

Patients have advanced stage cancer. This study is a gene transfer research study using special immune cells.

The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Investigators hope that both will work better together. Antibodies are proteins that protect the body from diseases caused from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected with germs. Both antibodies and T cells have been used to treat patients with cancers: they both have shown promise, but have not been strong enough to cure most patients.

T lymphocytes can kill tumor cells but there are normally not enough of them or they are not able to kill all the tumor cells. We have done research in which we have grown "extra" T lymphocytes. We have added genes to those T lymphocytes to help them to recognize tumor cells. Although the results have been promising, we are still doing more research in this area.

Antibodies usually circulate in blood and are secreted by other cells of the immune system in response to the presence of germs or abnormal cells in the body. The antibody used in this study is called anti-HER2 (Human Epidermal Growth Factor Receptor 2). This antibody sticks to HER2-positive cancer cells because of a substance on the outside of these cells called HER2.

Read the detailed description

The patient will give blood to grow T cells on either one to two separate occasions. Then, the EBV-specific T cells will be made. These cells will be grown and frozen. To get the HER2 antibody (and the CD28) and the DNR to attach to the surface of the EBV-T cells, the antibody gene and the DNR gene will be inserted into the EBV-T cell. This is done with two viruses called retroviruses that have been made for this study. One will carry the antibody gene into the T cell and the other the DNR gene.

When the patient is enrolled on the study, they will be assigned to a dose of HER2-DNR EBV-T cells. The subject will be given one dose of cells into the vein through an IV line. The injection will take between 1 and 10 minutes. The patient will be followed in the clinic after the injection for 1 to 4 hours. The treatment will be given by the Center for Cell and Gene Therapy at Texas Children's Hospital or Houston Methodist Hospital.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TGFBeta resistant HER2/EBV-CTLsBiological

    Also called HER2-DNR EBV T cells

    Each patient will receive one injection of the TGFBeta resistant HER2/EBV-specific CTLs. Each pt will be followed for 6 weeks after the CTL infusion for evaluation of dose limiting toxicity (DLT).

    Patients may receive up to six additional doses of the T cells at 6 to 12 weeks intervals.

What is being measured

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

  1. Number of Patients with dose limiting toxicity.

    Determine safety of one IV injection of autologous TGFBeta-resistant cytotoxic T cells (CTL) directed to Epstein Barr virus (EBV) through their native receptor and HER2 through their chimeric antigen receptor (CAR) in patients with advanced HER2- positive cancers.

    Measured: 6 weeks

Secondary outcomes (2)
  1. Area under the growth curves (AUC) over time for T cell frequencies.

    To compare the survival and the immune function of the TGFBeta-resistant and non resistant components of the infused CAR-CTL.

    Measured: 15 years

  2. Decrease in tumor after the CTL infusion

    To assess the anti-tumor effects of the infused CAR-CTL.

    Measured: 15 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TGFBeta resistant HER2/EBV-CTLs in people with HER2 Positive Malignancies, run by Baylor College of Medicine 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 24 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 18 Sep 2018. 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?

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 Patients with dose limiting toxicity. (time frame: 6 weeks). 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 Sep 2018.
