Biological Therapy in Treating Patients With Multiple Myeloma That Has Recurred Following Bone Marrow Transplantation

Multiple Myeloma and Plasma Cell Neoplasm Clinical Trial

Official title: Phase II Study of Salvage Cellular Immunotherapy for Patients With Persistent or Recurrent Multiple Myeloma After Allogeneic Bone Marrow Transplantation From an HLA-Matched Sibling Donor

Status Completed

Clinical Trial Summary

RATIONALE: White blood cells from donors may be able to kill cancer cells in patients with multiple myeloma that has recurred following bone marrow transplantation.

PURPOSE: This phase II trial is studying how well giving donor white blood cells works in treating patients with recurrent multiple myeloma who have undergone bone marrow transplantation.

Clinical Trial Description

OBJECTIVES:

• Assess the response rate of patients with recurrent multiple myeloma after an allogeneic marrow transplant from a genotypically HLA identical sibling donor treated with donor lymphocyte infusions as salvage therapy .

• Evaluate the safety and toxicity of this treatment when used as salvage therapy in these patients.

OUTLINE: Patients receive initial cell dose of donor lymphocytes (CD3+ cells) IV over 15-30 minutes. Patients with rapidly progressive disease may skip the initial cell dose and proceed directly to dose escalation to receive CD3+ cells at a higher cell dose. Patients who achieve complete response to the initial treatment may receive up to 2 additional courses of escalating doses of CD3+ cells 8-12 weeks apart in the absence of unacceptable toxicity. Patients are evaluated at 4 and 8 weeks after each infusion. Patients with disease progression at 8 weeks are retreated at that time. Patients who achieve partial response or stable disease at 8 weeks are re-evaluated at 12 weeks and may then be retreated.

Patients are followed every 2 weeks for 3 months, once a month for 9 months, and then every 2 months thereafter.

PROJECTED ACCRUAL: A total of 22 patients will be accrued for this study within 2 years. ;
