Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Multiple Myeloma and Plasma Cell Neoplasm Biological: anti-thymocyte globulin Phase 2

Detailed Description:



  • 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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 12 participants
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study of Thymoglobulin in Patients With Multiple Myeloma Who Are Candidates for Allogeneic or Autologous Stem Cell Transplant
