Summary

RATIONALE: Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemoprotective drugs, such as amifostine, may protect normal cells from the side effects of chemotherapy. Giving chemotherapy with a peripheral stem cell transplant once or twice, using stem cells from the patient or an identical brother or sister, may allow more chemotherapy to be given so more cancer cells are killed. Giving maintenance therapy after a stem cell transplant may kill any cancer cells that remain. It is not yet known which dose of melphalan is more effective in treating multiple myeloma.

PURPOSE: This randomized phase III trial is studying two different doses of melphalan to compare how well they work when given together with amifostine followed by one or two autologous or syngeneic stem cell transplants and maintenance therapy in treating patients with stage II or stage III multiple myeloma.

Clinical Details

Official title: A Multi-Center Phase III Study of Autologous Transplantation for Patients With Multiple Myeloma Comparing Melphalan 280 mg/m + Amifostine With Melphalan 200mg/m + Amifostine

Study design: Treatment, Randomized, Active Control

Primary outcome: Compare complete response and near complete response rate after completion of the first transplant

Detailed description: OBJECTIVES:

Primary

- Compare the complete response (CR) and near-CR rates in patients with stage II or III

multiple myeloma treated with induction therapy comprising two different doses of high-dose melphalan and amifostine followed by a single autologous or syngeneic peripheral blood stem cell transplantation (PBSCT).

Secondary

- Compare the toxic effects of these regimens in these patients.

- Determine the CR and near-CR rates in patients who fail to achieve a CR or near-CR

after a single autologous or syngeneic PBSCT and subsequently receive a second course of induction therapy comprising high-dose melphalan and amifostine followed by a second autologous or syngeneic PBSCT.

- Compare the time to progression in patients treated with these regimens followed by

maintenance therapy comprising clarithromycin, thalidomide, and dexamethasone.

OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified according to pre-transplantation response (< a partial response [PR] vs > a PR), pre-transplantation serum beta-2 microglobulin level (< 5 mg/dL vs > 5 mg/dL), and the presence of deletion on chromosome 13 by fluorescence in situ hybridization (yes vs no).

- Induction therapy: Patients are randomized to 1 of 2 treatment arms.

- Arm I (high-dose melphalan and amifostine): Patients receive amifostine IV over

3-5 minutes on days - 3 and -2 followed by high-dose melphalan IV over 15-30

minutes on day - 2.

- Arm II (higher-dose melphalan and amifostine): Patients receive amifostine as in

arm I and melphalan as in arm I but at a higher dose.

- Autologous or syngeneic peripheral blood stem cell transplantation (PBSCT): At least 20

hours after completion of melphalan, all patients undergo autologous or syngeneic PBSCT on day 0.

Patients undergo restaging of the disease between days 80-90. Patients with progressive disease are removed from the study. Patients who achieve a complete response (CR) or near-CR proceed to maintenance therapy. Patients who do not achieve a CR or near-CR undergo additional induction therapy as in arm I followed by a second autologous or syngeneic PBSCT. Patients again undergo restaging of the disease 80-90 days later. Patients with progressive disease are removed from the study. Patients without progressive disease proceed to maintenance therapy.

- Maintenance therapy: Beginning 90-120 days after first or second PBSCT, patients

receive oral clarithromycin twice daily and oral thalidomide once daily for 1 year. Patients also receive oral dexamethasone once weekly for 1 year followed by a taper for 8 weeks. Treatment with thalidomide alone then continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 130 patients will be accrued for this study.
