Melphalan and Busulfan Followed By Donor Peripheral Stem Cell Transplant, Tacrolimus, and Methotrexate in Treating Patients With Multiple Myeloma

Multiple Myeloma and Plasma Cell Neoplasm Clinical Trial

Official title: A Phase II Study of Intravenous Melphalan and Busulfan Followed by HLA-Matched, Allogeneic Peripheral Blood Stem Cell Transplant for the Treatment of Multiple Myeloma

Status Completed

Clinical Trial Summary

RATIONALE: Giving chemotherapy, such as melphalan and busulfan, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus and methotrexate before or after transplant may stop this from happening.

PURPOSE: This phase II trial is studying how well giving melphalan together with busulfan followed by donor peripheral stem cell transplant, tacrolimus, and methotrexate works in treating patients with multiple myeloma.

Clinical Trial Description

OBJECTIVES:

Primary

• Evaluate transplant-related mortality in patients with multiple myeloma treated with a myeloablative conditioning regimen comprising melphalan and busulfan followed by HLA-matched, allogeneic peripheral blood stem cell transplantation (PBSCT) and graft-vs-host disease prophylaxis with tacrolimus and methotrexate.

Secondary

• Determine the disease response in patients treated with this regimen.

• Determine the 1-year progression-free survival and overall survival in patients treated with this regimen.

OUTLINE:

• Conditioning regimen: Patients receive melphalan IV over 30 minutes on day -6 and busulfan IV over 3 hours on days -5 to -3.

• Peripheral blood stem cell transplantation (PBSCT): Patients undergo HLA-matched, related donor, allogeneic PBSCT on day 0.

• Graft-versus-host disease (GVHD) prophylaxis: Patients receive tacrolimus IV continuously or orally twice daily beginning on day -2 and continuing until day 80 followed by a taper until day 180 in the absence of GVHD or disease progression. Patients also receive methotrexate IV on days 1, 3, 6, and 11.

After completion of study treatment, patients are followed every 6 months for 2 years and then annually thereafter.

PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study. ;
