Key requirements

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 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Patients from the Bone Marrow Transplant service at the Indiana University Melvin and Bren Simon Cancer Center.

Who may be able to join

  • Patients with hematological malignancies who are undergoing evaluation for autologous or allogeneic stem cell transplants will be eligible, if: (1)They have no circulating neoplastic cells in the peripheral blood as assessed by routine morphology or flow cytometry. (2)Patients with acute myeloid or lymphocytic leukemia are in complete remission
  • First-degree relatives of patients evaluated for stem cell transplantation will be eligible if: (1) Willing to undergo testing for HIV and hepatitis B and C (free of charge) (2) Not pregnant at time of collection of blood (3)In good general health (4) No prior history of malignancy. (5) Age 18 years or older if donating apheresis product. (Because of the relatively invasive nature of the leukopheresis procedure and difficulties in obtaining consent, children <18 who are first degree relatives of the patient will not undergo apheresis for studies on this protocol)
  • Written informed consent

About this study

The doctors in the Bone Marrow Transplant Service at the Indiana University Cancer Center are working to better understand how the immune cells that cause graft-versus-host disease (a major complication of stem cell transplantation in which the donor immune cells attack the patient's organs) can be selectively removed from the graft, leaving other immune cells that fight infections.

Read the detailed description

The purpose of this research is to study how immune cells (called T cells) that cause graft-versus-host disease (GVHD) can best be selectively separated from other T cells and removed from the cells that will be returned to the cancer patient's body. These other T cells may protect against infection when given to patients after a stem cell transplant. The removal of cells that cause GVHD would allow doctors to safely give back the T cells that protect against infection, without the risk of GVHD.

What participants receive

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

  • collection of peripheral blood and apheresis samplesProcedure or surgery

    Sixty mL of peripheral blood will be collected from consenting eligible donors. Additionally, after the laboratory techniques have been fully evaluated, leukopheresis samples will also be collected.

What is being measured

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

  1. To develop the optimum conditions for activating the maximum number of alloreactive T cells from clinical scale samples

    Measured: 5 years

Secondary outcomes (1)
  1. To develop a GMP grade high throughput, flow through immunomagnetic cell separation system for clinical scale depletion of alloreactive T cell, capable of t3log10 depletion of alloreactivity while retaining >80% third party reactivity.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Hematologic Malignancies and Hematopoietic Stem Cell Transplantation, run by Indiana University.

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 3 inclusion and 1 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: withdrawn, as of the sponsor's last update on 19 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

To develop the optimum conditions for activating the maximum number of alloreactive T cells from clinical scale samples (time frame: 5 years). 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 19 Sep 2014.
