About this study

Official title: Pilot Study Of Allogeneic Peripheral Blood Progenitor Cell Transplantation In Patients With Chemotherapy-Refractory Or Poor-Prognosis Metastatic Breast Cancer

RATIONALE: Giving chemotherapy, such as fludarabine and melphalan, before a donor peripheral blood stem cell transplant helps stop the growth of tumor cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining tumor cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving antithymocyte globulin, cyclosporine, and methotrexate before or after the transplant may stop this from happening.

PURPOSE: This phase II trial is studying how well antithymocyte globulin, high-dose melphalan, fludarabine, and allogeneic peripheral stem cell transplant work in treating patients with metastatic adenocarcinoma of the breast.

Read the detailed description

OBJECTIVES:

Primary

  • Determine the toxicity and tolerability of allogeneic peripheral blood stem cell transplantation after a nonmyeloablative preparative regimen comprising anti-thymocyte globulin, high-dose melphalan, and fludarabine in women with chemotherapy-refractory or poor-prognosis metastatic adenocarcinoma of the breast.
  • Determine the ability of this preparative regimen to facilitate long-term engraftment of allogeneic stem cells and lymphocytes in these patients.
  • Determine the response in measurable/evaluable disease and its temporal relationship to the preparative chemotherapy used and to the onset of clinical graft-versus-host disease (GVHD) in patients treated with this regimen.

Secondary

  • Determine the progression-free and overall survival of patients treated with this regimen.
  • Determine the tumor response and its temporal relationship to administration of high-dose chemotherapy and to the onset of GVHD in patients treated with this regimen.
  • Determine the frequency and durability of the induction of full donor chimerism of lymphocytes in patients treated with this regimen.

OUTLINE: This is a nonrandomized, pilot study.

  • Nonmyeloablative preparative regimen: Patients receive fludarabine IV over 30 minutes on days -8 to -4, anti-thymocyte globulin IV over 4 hours on days -7 to -4, and high-dose melphalan IV over 30 minutes on days -3 and -2.
  • Graft-versus-host disease (GVHD) prophylaxis: Patients receive cyclosporine IV (and then orally when tolerated) every 12 hours beginning on day -4 and tapered after day 42 (if no GVHD occurs) or after day 90 (if grade I acute GVHD occurs). Patients also receive methotrexate IV on days 1, 3, and 6.
  • Allogeneic peripheral blood stem cell transplantation (PBSCT): Patients undergo allogeneic PBSCT on day 0. Patients also receive filgrastim (G-CSF) IV or subcutaneously beginning on day 0 and continuing until blood counts recover.
  • Donor lymphocyte infusion (DLI): Patients who show disease progression or fail to achieve full donor type T-cell chimerism (at least 90% donor derived T-cells) by the 90-day assessment posttransplantation, and have no evidence of active GVHD may receive DLI. Patients who have unresponsive disease with no active GVHD receive subsequent DLIs every 6-8 weeks.

Patients are followed at 1, 3, 6, 12, 18, 24, 30, and 36 months.

PROJECTED ACCRUAL: A total of 10 patients will be accrued for this study.

    Measured: 100 days post transplant

Secondary outcomes (4)
  1. Progression-free Survival

    Progression assessed by CT scan

    Measured: From date of transplant until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 6 months

  2. Overall Survival

    Measured: 1 year from the time of transplant

  3. Response as Measured at 12 Months Post Allografting

    response (partial and complete) assessed by CT scan at 12 months post allografting

    Measured: From date of transplant until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months

  4. Frequency of the Induction of Full Donor Chimerism of Lymphocytes as Measured at 1 Month Post Allografting

    Measured: 1 month post allografting

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing anti-thymocyte globulin, filgrastim and graft-versus-tumor induction therapy in people with Breast Cancer, run by University of California, San Diego 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?

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 5 Jun 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 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 24 Nov 2014). 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 Adverse Events (time frame: 5 years post transplant). 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 5 Jun 2023.
