Multiple Myeloma Clinical Trial
Melphalan, Peripheral Stem Cell Transplantation, and Interleukin-2 Followed by Interferon Alfa in Treating Patients With Advanced Multiple Myeloma
Summary
This phase II trial studies the effectiveness of melphalan, peripheral stem cell transplantation, and interleukin-2 followed by interferon alfa in treating patients who have advanced multiple myeloma (MM). 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. Interleukin-2 (IL2) may stimulate a person's white blood cells to kill multiple myeloma cells. Interferon alfa may interfere with the growth of cancer cells
Full Description
PRIMARY OBJECTIVES:
I. Evaluate initial response to therapy, time to disease progression, and overall survival in MM patients treated with melphalan, IL2- incubated peripheral blood stem cells, and sequential IL2.
SECONDARY OBJECTIVES:
I. Evaluate grade 3-4 toxicities encountered by younger (< 56 years old) and older (>56 years old) advanced multiple myeloma patients treated with melphalan, IL2-incubated peripheral blood stem cells, and sequential IL2.
OUTLINE:
Patients receive melphalan intravenously (IV) over 2-3 hours on day -2 and an infusion of IL-2-treated autologous or syngeneic peripheral blood stem cells on day 0. Beginning on day 0, patients also receive IL-2 IV continuously over 5 days followed by 2 days off. Treatment with IL-2 repeats weekly for 4 weeks. Beginning 1 month later, patients undergo maintenance therapy comprising interferon alfa subcutaneously (SC) 3 times a week in the absence of disease progression or unacceptable toxicity.
Eligibility Criteria
Inclusion Criteria:
Patient must be less than 70 years old
Patients with advanced Multiple Myeloma that meet the eligibility requirements for mobilization/debulking with Cytoxan/VP-16/G-CSF, Cytoxan/Taxol/G-CSF, or Cytoxan/G-CSF (according to protocol 506.03); if clinically indicated a lower dose of cytoxan than 4g/m2 may be used for mobilization based on the attending's discretion; also, if the patients had previously collected PBSC of sufficient number in the past and meet the other eligibility requirements, they may be entered on this study after approval by the PI
