UARK 98-026 TT II: Multiple Myeloma Evaluating Anti-Angiogenesis With Thalidomide and Post-Transplant Consolidation Chemotherapy

All patients will be randomly assigned to receive thalidomide 400 mg as an oral, once daily dose throughout induction and 100mg between transplants after platelets are greater than 50,000μl and 200 mg post transplant consolidation, and a reduced dose of 100 mg on alternating days during the first year of maintenance and 50 mg qod thereafter versus no thalidomide. Thalidomide will be held during conditioning, transplant procedure, and recovery following transplant. It may be resumed once plateletrecovery is complete after each transplant

Doxorubicin may be further diluted in 5% dextrose or sodium chloride injection and should be administered slowly into tubing of a freely flowing intravenous infusion with great care taken to avoid extravasation.

G-CSF will be administered at a dose of 10mcg/kg or GM-CSF at a dose of 10 mcg/kg. G-CSF or GM-CSF will begin one day after completion of chemotherapy and continued during repeated apheresis and discontinued upon completion of apheresis.

GM-CSF at a dose of 10 μg/kg SC, divided in 2 doses each day, will begin one day after completion of chemotherapy and continued during repeated apheresis and discontinued upon completion of apheresis.
