Summary

RATIONALE: Giving low doses of chemotherapy before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving umbilical cord blood transplant together with fludarabine, melphalan, and antithymocyte globulin works in treating patients with hematologic cancer.

Clinical Details

Official title: Transplantation of Two Partially Matched Umbilical Cord Blood Units Following Reduced Intensity Conditioning to Enhance Engraftment and Limit Transplant-Related Mortality in Adults With Hematologic Malignancies

Study design: Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Number of Participants With 100 Day Transplant-related Mortality (TRM)

Secondary outcome:

Number of Patients That Engrafted Blood Counts by 30 Days After Transplant

Percentage of Donor and Host Chimerism of Each Cord Blood Unit

Number of Patients Who Experience Acute and Chronic Graft-vs-host Disease After Transplant.

Number of Patients Who Experience Disease Relapse Post-transplant

Number of Patients Who Survive Following Treatment on This Protocol

Detailed description: OBJECTIVES: Primary

- To evaluate the 100-day transplant-related (non-relapse) mortality in patients with

hematologic malignancies undergoing reduced-intensity conditioning comprising fludarabine phosphate, melphalan, and anti-thymocyte globulin followed by sequential umbilical cord blood transplantation (UCBT) from 2 partially-matched unrelated donors. Secondary

- To evaluate the 12-month transplant-related (non-relapse) mortality.

- To evaluate the days to neutrophil engraftment (ANC > 500/mm³).

- To evaluate the days to platelet engraftment (platelet count > 20,000/mm³

[unsupported]).

- To evaluate the risk of acute and chronic graft-vs-host disease.

- To evaluate percent donor chimerism contribution of each cord unit.

- To evaluate relapse rate.

- To evaluate disease-free and overall survival.

- To evaluate transfusion support needed for UCBT recipients.

OUTLINE:

- Conditioning regimen: Patients receive fludarabine phosphate IV over 30 minutes on days

- 7 to -3, melphalan IV over 30-60 minutes on day -2, and anti-thymocyte globulin IV

over 4-6 hours on days - 4 to -2.

- Transplantation: Patients undergo two sequential umbilical cord blood transplantations

on day 0.

- Graft-vs-host disease (GVHD) prophylaxis: Patients receive tacrolimus IV continuously

and then orally twice daily beginning on day - 1 and continuing until day 60, followed

by a taper until day 180 in the absence of GVHD. Patients also receive mycophenolate mofetil IV or orally twice daily beginning on day 0 and continuing until day 30, followed by a taper until day 60 in the absence of GVHD. After completion of study treatment, patients are followed periodically.

Eligibility

Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.

cell transplantation is deemed clinically appropriate, including any of the following:

- Chronic myelogenous leukemia, meeting one of the following criteria:

- In first chronic phase AND failed imatinib mesylate therapy, defined as

failure to obtain a hematologic remission by 3 months or major cytogenetic response (Ph+ cells < 35%) by 12 months, or demonstrated clonal evolution or disease progression while on therapy

remission is defined as < 5% blasts in bone marrow, no definitive evidence of disease by morphology, flow cytometry, or genetic studies, and no circulating blasts. Neutrophil and platelet count recovery will not be required.

following criteria:

- Failed ≥ 1 prior chemotherapy regimen, including fludarabine, or autologous

stem cell transplantation

- Chemosensitive or stable, non-bulky disease prior to transplant

- Received ≤ 3 prior chemotherapy regimens (monoclonal antibody therapy and

involved-field radiotherapy are not considered prior regimens)

follicular center [grade 1 or 2] lymphoma, or marginal zone lymphoma), meeting all of the following criteria:

- Failed ≥ 1 prior chemotherapy regimen or autologous stem cell

transplantation

- Chemosensitive or stable, non-bulky disease prior to transplant

following criteria:

chemotherapy or autologous stem cell transplantation

- Relapsed after conventional therapies AND not a candidate for autologous

stem cell transplantation

> 3. 7 x 10^7 nucleated cells/kg (pre-freeze dose) NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
