Antithymocyte Globulin in Treating Patients Undergoing Stem Cell Transplant for Multiple Myeloma
A Phase II Study of Thymoglobulin in Patients With Multiple Myeloma Who Are Candidates for Allogeneic or Autologous Stem Cell Transplant

RATIONALE: Biological therapies, such as antithymocyte globulin, may stimulate the immune system in different ways and stop cancer cells from growing.

PURPOSE: This phase II trial is studying how well antithymocyte globulin works in treating patients undergoing stem cell transplant for multiple myeloma.



  • Determine the response rate at 4 weeks in patients with multiple myeloma treated with anti-thymocyte globulin at least 4 to 6 weeks prior to undergoing conditioning therapy for allogeneic or autologous stem cell transplantation.


  • Determine the toxicity of this drug, in terms of formation of antirabbit antibodies, in these patients.

OUTLINE: This is an open-label, multicenter study.

Patients receive anti-thymocyte globulin IV over 6 hours on day 1 and over 4 hours on days 3 and 5. Treatment begins 4 to 6 weeks prior to undergoing conditioning therapy for autologous or allogeneic stem cell transplantation.

After completion of study treatment, patients are followed at 28 days.

PROJECTED ACCRUAL: A total of 12 patients will be accrued for this study.
