Optimized Donor Selection, Nonmyeloablative BMT for B-cell Lymphomas With Post-transplantation Cy and Rituximab

• Status: Terminated
• Trial end date: 2013-07-17
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation and rituximab works in treating patients with B-cell lymphoma or chronic lymphocytic leukemia who are undergoing an allogeneic (donor) bone marrow transplant. The type of bone marrow transplant is a less intensive or "mini" transplant using a relative as the bone marrow donor. The donated bone marrow stem cells may replace the patient's immune system cells and help destroy any remaining cancer (graft-versus-tumor effect). Patients undergoing this type of transplant often have more than one relative who could be a donor. The trial is also studying a new way of choosing amongst possible donors which might improve how the rituximab works.

Criteria

Inclusion Criteria:

• Poor-risk CD20+, B-cell lymphoma, as follows:

• Low grade B-cell lymphoma that has failed at least two prior therapies (excluding single agent rituximab), or undergone histologic conversion (if histologic conversion, PR or CR is required):

1. Follicular grade 1 or 2 lymphoma

2. Follicular lymphoma not otherwise specified

3. Marginal zone (or MALT) lymphoma

4. Lymphoplasmacytic lymphoma / Waldenstrom's macroglobulinemia

5. Hairy cell leukemia

6. Small lymphocytic lymphoma / chronic lymphocytic leukemia (SLL/CLL)

7. Low grade B-cell lymphoma, unspecified

8. Nodular lymphocyte-predominant Hodgkin lymphoma

• Poor-risk small lymphocytic lymphoma or chronic lymphocytic leukemia, defined by a 17p deletion, 11q deletion, or histologic conversion (if histologic conversion, PR or CR is required)

• Aggressive B-cell non-Hodgkin's lymphoma that has failed at least one prior regimen of multiagent chemotherapy, is in PR (partial remission) or CR (complete remission), and patient is either ineligible for autologous hematopoietic BMT or autologous BMT is not recommended:

1. Follicular grade 3 lymphoma

2. Histoconversion of low-grade B-cell lymphoma (including SLL/CLL) to aggressive B-cell non-Hodgkin's lymphoma

3. Mantle cell lymphoma

4. Diffuse large B-cell lymphoma (excluding primary CNS [central nervous system] lymphoma)

5. "Gray zone" or composite lymphomas with combined features of primary mediastinal large B-cell and Hodgkin's lymphoma

6. Burkitt's lymphoma/leukemia

7. Atypical Burkitt's lymphoma/leukemia (high grade B-cell lymphoma, unclassified, including that with features intermediate between Burkitt's and diffuse large B-cell lymphoma)

• Must have a related donor who is at least HLA haploidentical

• Any previous BMT must have occurred at least 3 months prior

• Left ventricular ejection fraction at least 35%
