RATIONALE: Dexamethasone is used to treat multiple myeloma. Drugs used in chemotherapy may stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Plasma exchange is a process in which certain cells are separated from the plasma in the blood by a machine and then only the cells are returned to the patient. Dexamethasone and plasma exchange may be an effective treatment for acute kidney failure caused by multiple myeloma. It is not yet known whether giving dexamethasone and chemotherapy together with plasma exchange is more effective than giving dexamethasone and chemotherapy alone in treating patients with multiple myeloma and acute kidney failure.

PURPOSE: This randomized phase III trial is studying dexamethasone, chemotherapy, and plasma exchange to see how well they work compared with dexamethasone and chemotherapy alone in treating patients with newly diagnosed multiple myeloma and acute kidney failure.

OBJECTIVES:

Primary

* Compare the effect of dexamethasone and cytotoxic chemotherapy with vs without plasma exchange on the likelihood of renal recovery (i.e., dialysis-independent at 100 days) in patients with newly diagnosed multiple myeloma and acute renal failure.

Secondary

* Compare the overall survival of patients treated with these regimens.
* Compare the quality of life of patients treated with these regimens.
* Determine the value of renal histology in predicting recovery of renal function in these patients.
* Determine the value of serum free light chain assay in determining disease response and renal function recovery in these patients.

OUTLINE: This is a randomized, controlled, open-label, multicenter study. Patients are stratified according to planned chemotherapy (vincristine and doxorubicin hydrochloride (VA) or VA-like chemotherapy vs thalidomide-containing chemotherapy vs alkylating agent vs other), frequency of chemotherapy courses (1-3 weekly vs 4 weekly), need for dialysis at randomization (yes vs no), and age (\< 65 years vs ≥ 65 years). Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive oral dexamethasone, at least twice daily, on days 1-4 and 9-12. Patients undergo plasma exchange by cytocentrifugation or plasmafiltration over 2-3 hours in weeks 1 and 2 (7 treatments total; 4 of them in week 1). Patients then receive planned chemotherapy per local clinician on days 17-100. Chemotherapy may continue after 100 days at the discretion of the local clinician.
* Arm II: Patients receive dexamethasone and planned chemotherapy as in arm I. Quality of life is assessed at baseline, day 100, and 6 and 12 months.

After completion of study treatment, patients are followed at 6 and 12 months and then annually thereafter.

This randomized controlled, multi-center study will carry out to assess the efficacy of GB-0998 compared to plasmapheresis in the treatment of the generalized Myasthenia Gravis based on the changes in Quantitative Myasthenia Gravis score (QMG score) as primary endpoint, and in addition, to assess the safety of GB-0998
