About this study

Official title: Phase II Study of Purging of Circulating Tumor Cells (CTCs) From Metastatic Breast Cancer Patients

The goal of this clinical research study is to learn the relationship of high-dose chemotherapy (HDCT) and circulating tumor cells (CTCs) in controlling metastatic breast cancer. The study also will investigate the role of CTCs in breast cancer.

Read the detailed description

Cyclophosphamide is designed to interfere with the multiplication of cancer cells, which may slow or stop their growth and spread throughout the body. This may cause the cancer cells to die. Carboplatin and thiotepa are designed to interfere with the growth of cancer cells by stopping cell division, which may cause the cells to die. Mesna is designed to prevent toxicities from cyclophosphamide. Granulocyte colony-stimulating factor (G-CSF or GCSF) is designed to help your white blood count recover after transplant.

If you are found to be eligible to take part in this study, you will be given G-CSF twice a day through a needle under the skin (subcutaneous injection), on Days 1-5. On Day 5, stem cell collection will begin. You will have a catheter placed into a vein in your chest. A central venous catheter is a sterile flexible tube that will be placed into a large vein while you are under local anesthesia. Your physician will explain this procedure to you in more detail, and you will be required to sign a separate consent form for this procedure.

If further shrinkage of tumor is needed, the doctor may use chemotherapy combined with G-CSF described above. Your doctor will explain this procedure to you in more detail, and you will be asked to sign a separate consent form for this procedure.

Blood will be removed from your body through the catheter and passed through a machine that separates the stem cells from the other cells. The stem cells will be frozen for storage, and the blood will be returned to your body. This 3-hour process is called apheresis. The process will be done once a day for 1-6 days until enough stem cells are collected. Blood ( about 4 teaspoons) will be collected at the first Apheresis to have as a comparison sample to check for any breast cancer leftover in the blood.

The collected blood cells will go through a filter to select out the blood stem cells and the CTCs will be left behind.

Blood (about 2 tablespoons) will be drawn daily during peripheral blood stem cell collection.

On Days 6, 5, 4, and 3 before the transplant, you will receive cyclophosphamide, mesna, thiotepa, and carboplatin through a needle in your vein. Blood (about 2 teaspoons) will be drawn for routine tests.

On Day 0, your stem cells will be transplanted. Stem cells will go through a device to remove the breast cancer cells. If the bone marrow is collected because there was not enough stem cells, researchers will not treat the bone marrow to remove breast cancer cells. Collected breast cancer cells will be studied to understand the biological role of these cancer cells.

After the transplant, G-CSF will be given through a needle under your skin until the white blood cell count is normal for 3 days in a row.

Blood (about 2 tablespoons) will be drawn daily after the transplant while you are still in the hospital. You are expected to remain in the hospital for 3 weeks. Once you are released from the hospital, you will have blood (about 2 tablespoons) drawn for routine tests every week until your cell counts recover.

Five (5) weeks after your transplant, if your doctor thinks it is needed, you will have radiation therapy, hormonal therapy, or receive trastuzumab.

At Months 1, 3, 6, 9, 12, 16, 20, and 24 after the transplant, your complete medical history will be recorded, and you will have a physical exam. You will have a chest X-ray and bone scan. If your doctor thinks it is needed, you will have an x-ray of hot spots which are areas that show positive on the bone scan. If your doctor thinks it is needed, you may have a CT scan of the head, a mammogram, or a breast ultrasound performed. At Months 1 and 3 after the transplant, you will have a PET/CT scan. At Months 6, 9, 12, 16, 20, and 24 after the transplant, you will have a CT scan of the chest and abdomen then as needed to check the status of the disease. Blood (about 2 teaspoons) will be drawn to measure cancer markers and CTCs.

While on study you must notify the doctor of any new drugs you are taking.

This is an investigational study. The transplant is not FDA approved. The drugs G-CSF, cyclophosphamide, carboplatin, and thiotepa are all approved by the FDA and commercially available. The CliniMACS device is not commercially available or FDA approved. The CliniMACS device is being used in research only and will be provided free of charge. Up to 70 patients will take part in this study. All will be enrolled at M. D. Anderson.

What is being measured

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

  1. Number of Participants With Reduction in CTCs Following High-dose Chemotherapy With Purged Autologous Stem Cell Products

    Number of circulating tumor cells (CTCs) measured at one month post autologous hematopoietic stem cell transplantation (AHST), considered both as longitudinal values and compared to the baseline number of CTCs.

    Measured: Baseline to 1 month post AHST

Secondary outcomes (1)
  1. Median Progression Free Survival (PFS)

    Kaplan-Meier estimate of the median time from randomization to death from any cause or first observed disease progression. PFS time measured in months.

    Measured: Overall study (baseline to disease progression)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Carboplatin, Cyclophosphamide and Thiotepa in people with Breast Cancer and Metastatic Breast Carcinoma, run by M.D. Anderson Cancer Center 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 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 10 Apr 2013. 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?

Yes. Results are posted in the registry (first posted 10 Apr 2013). 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 With Reduction in CTCs Following High-dose Chemotherapy With Purged Autologous Stem Cell Products (time frame: Baseline to 1 month post AHST). 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 10 Apr 2013.
