Melphalan With or Without Holmium Ho 166 DOTMP Followed by Peripheral Stem Cell Transplantation in Treating Patients With Multiple Myeloma

Status:
Completed
Trial end date:

Participant gender:
All
Summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radioactive drugs such as holmium Ho 166 DOTMP can kill cancer cells without harming healthy cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of melphalan with or without holmium Ho 166 DOTMP followed by peripheral stem cell transplantation in treating patients who have multiple myeloma.

Criteria
DISEASE CHARACTERISTICS: Newly diagnosed multiple myeloma (diagnosis within 12 months of
study) and scheduled to undergo autologous peripheral blood stem cell transplantation Prior
diagnosis of monoclonal gammopathy of undetermined significance (MGUS) or smoldering
myeloma (SMM) allowed if the criteria for diagnosis of multiple myeloma was met within 12
months of study Serum or urinary M-protein confirmation of diagnosis (IgA, IgD, IgG, IgE,
or light chain proteins) At least 10% plasma cells in bone marrow Must have received
induction therapy without disease progression or relapse after initial response Prior
induction therapy must have been completed no more than 6 months before stem cell
collection and no more than 9 months before transplantation Must have undergone stem cell
mobilization with cyclophosphamide IV and filgrastim (G-CSF) The following diagnoses are
excluded: Non-secretory multiple myeloma IgM myeloma Solitary bone or extramedullary
