Interferon Alfa Following Chemotherapy and Peripheral Stem Cell Transplantation in Treating Patients With Stage III or Stage IV Multiple Myeloma
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Interferon alfa may interfere with the growth of cancer cells.
PURPOSE: Phase II trial to determine the effectiveness of giving interferon alfa after chemotherapy and peripheral stem cell transplantation to patients who have stage III or stage IV multiple myeloma and who have been treated with high-dose melphalan.

|Study Start Date:||July 1996|
|Study Completion Date:||January 2004|
OBJECTIVES: I. Determine the effectiveness of interferon alfa-2b maintenance following high dose melphalan chemotherapy for patients with advanced multiple myeloma. II. Determine the response rate to high dose dexamethasone therapy using sequential noncrossresistant chemotherapies for patients with advanced multiple myeloma.
OUTLINE: Patients receive high dose dexamethasone on days 1-4, 9-12, and 17-20, followed by 4 weeks rest. Cyclophosphamide (CTX) is administered intravenously in combination with mesna following dexamethasone therapy. Sargramostim (GM-CSF) is initiated subcutaneously 1 day later and is continued for 10 days to support stem cell collections, which begin 10-14 days after CTX induction. Following 4 weeks of rest, melphalan (L-PAM) is administered over 1 hour. Stem cell rescue is begun 48 hours after L-PAM therapy. Three to 4 months after the first L-PAM course, a second L-PAM and stem cell rescue is undertaken. Interferon alfa-2b (IFN-A) maintenance is administered 3 times per week following bone marrow recovery from the first or second L-PAM courses. Patients achieving complete remission following the first course of L-PAM may proceed directly to IFN-A maintenance. Patients achieving greater than grade 3 nonhematologic toxicity or not achieving an absolute neutrophil count of greater than 1,000/mm3 by day 21 posttransplant are not eligible for dose escalation.
PROJECTED ACCRUAL: A minimum of 30 patients will be enrolled.
