RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher doses of chemotherapy to be given so that more plasma cells are killed. By reducing the number of plasma cells, the disease may progress more slowly.

PURPOSE: This phase II trial is studying how well autologous stem cell transplant works in treating patients with persistent or recurrent primary systemic (AL) amyloidosis.

Primary Outcome Measures:
  • Feasibility and tolerability [ Time Frame: 3 months after treatment and annually ] [ Designated as safety issue: Yes ]
  • Response and durability of response [ Time Frame: 3 months after treatment and annually ] [ Designated as safety issue: No ]
  • Evaluate immune reconstitution [ Time Frame: 3 months after treatment and annually ] [ Designated as safety issue: No ]

Enrollment: 12
Study Start Date: August 2001
Study Completion Date: October 2011
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: filgrastim
    16mcg/kg IV daily beginning three days prior to SCC through last day of SCC
    Other Name: G-CSF
    Drug: melphalan
    140-200 mcg/kg IV over two days
    Other Name: alkeran
    Procedure: autologous bone marrow transplantation
    infusion of previously collected stem cells on Day 0
    Procedure: peripheral blood stem cell transplantation
    infusion of previously collected stem cells on Day 0
Detailed Description:


  • Determine the feasibility and tolerability of second autologous stem cell transplantation in patients with persistent or recurrent AL amyloidosis.
  • Determine the response rate and durability of response in patients treated with this regimen.
  • Determine immune reconstitution in patients treated with this regimen.


  • Mobilization: Patients receive filgrastim (G-CSF) subcutaneously (SC) once daily beginning before the initiation of stem cell collection and continuing until the day before the completion of stem cell collection.
  • Preparative regimen: Patients receive high-dose melphalan IV over 20 minutes on days -3 and -2.
  • Autologous stem cell transplantation: Autologous stem cells are reinfused on day 0.

Patients are followed at 6 months, 1 year, and then annually thereafter.

PROJECTED ACCRUAL: A total of 19 patients will be accrued for this study within 5-6 years.
