Study of High-Dose Melphalan and Autologous Stem Cell Transplantation in Patients With Primary Light Chain Amyloidosis
OBJECTIVES: I. Determine the response, disease-free survival, and overall survival of patients with primary light chain amyloidosis treated with high-dose melphalan and autologous stem cell transplantation.
II. Determine the toxicity of this regimen in these patients.

- Response, disease-free survial, and overall survial; response will be determined by the change in organ dysfunction
- Toxicity of high dose chemotherapy regimen
|Study Start Date:||July 1999|
|Study Completion Date:||April 2004|
|Primary Completion Date:||April 2004 (Final data collection date for primary outcome measure)|
PROTOCOL OUTLINE: Patients may receive induction chemotherapy before study entry. Patients then receive filgrastim (G-CSF) or another growth factor for 4-6 days as peripheral blood stem cell (PBSC) mobilization. PBSC (or bone marrow) is harvested over 2-3 days.
Patients receive high-dose melphalan IV over 30 minutes twice daily on days -2 and -1. PBSC and/or bone marrow is reinfused on day 0. Patients receive G-CSF beginning on day 0 and continuing until blood counts recover. This course may be repeated 4-12 weeks later.
Patients are followed every 3 months for 1 year and then annually for 5 years.
