Combination Chemotherapy and Peripheral Stem Cell Transplantation in Treating Patients With Multiple Myeloma
Recruitment status was Active, not recruiting
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy and peripheral stem cell transplantation in treating patients who have multiple myeloma.
Multiple Myeloma and Plasma Cell Neoplasm
Biological: recombinant interferon alfa
Procedure: peripheral blood stem cell transplantation

|Official Title:||A Phase II Study of High Dose Late Intensification Therapy in Patients With Chemotherapy Sensitive Multiple Myeloma|
|Study Start Date:||October 1999|
OBJECTIVES: I. Determine the feasibility and activity of intensive therapy with 3 noncross resistant chemotherapeutic regimens (cyclophosphamide, etoposide, cisplatin, cytarabine, and tandem courses of high dose melphalan with stem cell rescue) in patients with chemotherapy sensitive multiple myeloma. II. Determine the incidence of hematologic and nonhematologic toxicities of this regimen in this patient population. III. Determine the time to hematologic recovery after high dose melphalan in these patients. IV. Determine the response rate after each course of therapy in these patients. V. Determine the disease free, relapse free, and overall survival of these patients treated on this regimen. VI. Determine the incidence of toxicities attributable to interferon alfa and the ability to continue interferon alfa therapy as maintenance in these patients.
OUTLINE: Patients are stratified according to the number of prior treatments (1 vs 2). Patients receive cyclophosphamide IV over 1 hour every 3 hours for 5 doses. Filgrastim (G-CSF) is administered subcutaneously daily beginning 3 days after cyclophosphamide and continuing through apheresis. Upon hematologic recovery, peripheral blood stem cells (PBSC) are collected over several days. After completion of the autologous stem cell harvest and hematologic recovery, patients receive etoposide IV and cisplatin IV continuously over 4 days, followed by cytarabine IV over 2 hours. Beginning 4-6 weeks later, patients receive melphalan IV over 15 minutes on 2 consecutive days. At least 48 hours after the second dose of melphalan, PBSC are reinfused. G-CSF is administered subcutaneously daily beginning 5 days after PBSC reinfusion until hematologic recovery. Patients remaining in remission after the first course of high dose melphalan receive a second course of melphalan 4 to 6 months after the first course. Melphalan IV is administered as above with reinfusion of the remainder of PBSC. After hematologic recovery from the second transplant, patients receive interferon alfa subcutaneously 3 days weekly until relapse. Patients are followed every 2 months.
PROJECTED ACCRUAL: Approximately 28 patients will be accrued for this study within 3 years.
