Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. GM-CSF may make cancer cells more sensitive to the effects of chemotherapy. Combining more than one drug with GM-CSF may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, consisting of cyclophosphamide plus vincristine, following GM-CSF in treating patients with multiple myeloma that has not responded to previous treatment.

Description:

OBJECTIVES: I. Determine the response rate of multiple myeloma patients when treated with cyclophosphamide and vincristine after cycling myeloma cells with sargramostim (GM-CSF). II. Evaluate whether Labelling Index (LI) changes influenced by GM-CSF would predict a group of patients that will respond to this particular course specific design. III. Determine the toxicity of GM-CSF in these patients.

OUTLINE: Patients receive subcutaneous injections of sargramostim (GM-CSF) once a day for 5 days. Two to 3 days later, patients receive cyclophosphamide IV over 30-45 minutes on day 1, vincristine IV bolus on day 8, and oral prednisone 4 times a day on days 1-4. Patients also receive subcutaneous injections of GM-CSF starting on day 2 and continuing for 10 days or until neutrophil count is at least 1000/mm3. Treatment continues every 3 weeks for a minimum of 6 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve at least stable response receive GM-CSF 3 times a week for up to 2 years. Patients are followed every 3-6 months.

PROJECTED ACCRUAL: A maximum of 30 patients will be accrued.
