Trial summary

RATIONALE: Giving chemotherapy before a donor natural killer (NK) cell infusion helps stop the growth of tumor cells. It also helps stop the patient's immune system from rejecting the donor's cells. Giving NK cells from a related donor may kill the tumor cells. Read more about this study

About this study

Official title: Allogeneic Natural Killer Cells in Patients With Advanced Metastatic Breast Cancer

RATIONALE: Giving chemotherapy before a donor natural killer (NK) cell infusion helps stop the growth of tumor cells. It also helps stop the patient's immune system from rejecting the donor's cells. Giving NK cells from a related donor may kill the tumor cells.

PURPOSE: This study furthers the research of previous studies (MT2003-01 and MT2004-25) which were to determine a specific preparatory regimen (cyclophosphamide and fludarabine) could create an environment in which infused NK cells can grow and effectively treat patients with relapsed AML. This study will test the previous regimen in patients with breast cancer.

Read the detailed description

We believe that administration of related allogeneic (donor) natural killer cells along with IL-2, rather than autologous natural killer cells will provide the most effective anticancer therapy in this setting, and wish to test this approach. To do this, we will select a related donor who is partially HLA-matched with the study subject, to increase the likelihood that donor natural killer cells will kill the subject's cancer cells. We will also give chemotherapy drugs to increase the subject's tolerance for the donor natural killer cells. We will test the use of donor natural killer (NK) cell infusions. The immune system has a special way that it sees and identifies cancer cells or foreign agents (like viruses). The subject's own NK cells may not attack their cancer because NK cells see the tumor cells as "self" (a coating on the cell surface identifies a cell as "self" or "non-self"). We have reason to believe that NK cells may not kill cancer cells because NK cells have special receptors that "turn them off" when they encounter cancer cells (by seeing them as "self"). We may be able to get around this problem by using donor NK cells. Finally, subjects will receive a dose of subcutaneous IL-2 3 times a week (for 2 weeks) which has been proven safe in our previous studies to stimulate the natural killer cells.

What participants receive

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

  • FludarabineDrug

    Also called Fludara

    administered intravenously 25 mg/m^2 times 5 doses

  • CyclophosphamideDrug

    Also called Endoxan, Cytoxan, Neosar, Procytox

    administered intravenously 60 mg/kg days times 2 doses.

  • Total body irradiationRadiation

    Also called radiation

    200 cGy (gray) on day -1

  • Natural killer cell infusionOther

    Also called NK cells

    Infused cell dose is within the range of 1.5-8.0 x 10^7/kg. Cell counts are based on total cells infused after the activation culture and washing determined on the morning of infusion.

  • Interleukin-2Biological

    Also called IL-2

    administered subcutaneously (10 MU) 3 times per week for 6 doses

Study groups in NCT00376805
Study groupRoleWhat they receive
All Treated PatientsExperimentalAll patients with advanced metastatic breast cancer treated with natural killer cells after receiving fludarabine, cyclosphosphamide and total body irradiation.

What is being measured

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

  1. Number of Patients Who Had Expansion of Natural Killer Cells

    Successful Natural Killer (NK) cell expansion is defined as detection of an absolute circulating donor-derived NK cell count of >100 cells/ul of whole blood 14 days after infusion with <5% donor T and B cells in mononuclear population (in metastatic breast cancer patients).

    Measured: Day 14

Secondary outcomes (3)
  1. Number of Patients by Disease Response

    Defined by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria:

    • Complete Response (CR: Disappearance of all target lesions
    • Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions
    • Stable Disease (SD): Neither sufficient shrinkage to qualify for PR or sufficient increase to qualify for PD
    • Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions of appearance of one or more new lesions of clinical benefit (CB; stable disease for greater than 6 months.

    Measured: 6 Months, 1 Year

  2. Number of Patients Who Died While on Study

    Number of patients who died within 100 days and after 100 days of natural killer (NK) treatment with or without total body irradiation.

    Measured: Within 100 days, After 100 days

  3. Overall Median Number of Days Patients Alive After Treatment

    Calculated median number of days of survival (patients alive days after treatment).

    Measured: First Day of Treatment Until Death

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Fludarabine, Cyclophosphamide and Total body irradiation in people with Breast Cancer, run by Masonic Cancer Center, University of Minnesota 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 18 inclusion and 2 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: stopped early, as of the sponsor's last update on 28 Dec 2017. 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 12 Aug 2010). 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 Patients Who Had Expansion of Natural Killer Cells (time frame: Day 14). 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 28 Dec 2017.
