Brief summary
This study has been designed to evaluate whether anti-angiogenesis therapy with thalidomide and whether additional chemotherapy after transplant will be beneficial. Another objective is to find out what kinds of side effects occur with this combination of treatment and how often they occur.
Detailed description
Treatment will be given in 4 phases or steps: Induction, Transplant 1 and 2, Consolidation, and maintenance. Induction is designed to induce (or bring about) myeloma into remission. Each patient enrolled on this study will be randomly assigned to receive the above treatment alone or in combination with a drug called thalidomide. Some patients may be eligible to receive the transplant as an outpatient, based on general health and other factors.After recovery from the transplant phase of the study (approximately 6 weeks), patients originally assigned to thalidomide will resume taking it and will continue taking it throughout the rest of the study treatment. All patients will receive post-transplant consolidation treatment, which in earlier studies has been found to be helpful in maintaining patients response after transplant. Therefore, all patients will receive a combination of drugs called D PACE which consists of Dexamethasone, Cis-Platinum, Adriamycin, Cyclophosphamide, and Etoposide. If you are also taking thalidomide, you will continue taking it throughout, and the treatment is called DT PACE to include the thalidomide. No sooner than 4 weeks, and no later than 12 weeks after consolidation and if your myeloma remains in remission after consolidation therapy is complete, you will begin the last phase of the study, which is maintenance. Maintenance is designed to keep your myeloma in remission long-term.
Interventions
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
Cytarabine (Ara-C) 400 mg/m2 in 250 ml D5W over one hour daily for four days (on days -5, -4, -3, -2). Start infusion 30 minutes after completion of BCNU on day -5.

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.
Etoposide (VP16) 200 mg/m2 in 500 ml D5W over one hour daily for four days (on days -5, -4, -3, -2). Start infusion 30 minutes after completion of BCNU on day -5. Start infusion at completion of cytarabine on following three days
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.

Etoposide (VP16) 200 mg/m2 in 500 ml D5W over one hour daily for four days (on days -5, -4, -3, -2). Start infusion 30 minutes after completion of BCNU on day -5. Start infusion at completion of cytarabine on following three days
Formulation: 1 mg/1 ml, 2 mg/2 ml, and 5 mg/ 5 ml vials. Vincristine should be administered intravenously through a freely-running IV. If it extravasates, it produces a severe local reaction with skin slough. FATAL IF GIVEN INTRATHECALLY, FOR INTRAVENOUS USE ONLY.

Eligibility
Inclusion criteria
* Patients must have newly diagnosed active multiple myeloma requiring treatment. Patients with a previous history of smoldering myeloma will be eligible if there is evidence of progressive disease requiring chemotherapy. * Protein criteria must be present in order to evaluate response.Non-secretory patients are eligible provided the patient has \> or = 20% plasmacytosis or multiple (\>3) focal plasmacytomas on MRI or diffuse hyperintense signal on STIR images in the absence of hematopoietic growth factors is seen. * All necessary baseline studies for determining stage, bloodwork, and bone marrow must be obtained within 35 days prior to registration. * Patients must have received no more than one cycle of prior chemotherapy including one month of Dexamethasone and Thalidomide for this disease. Patients may have received prior radiotherapy provided approval has been obtained by one of the study coordinators. * Patients must have a performance status of 0-2 based on SWOG criteria. Patients with a poor performance status (3-4), based solely on bone pain, will be eligible. * Patients with renal failure, even if on dialysis, are eligible if it is felt to be due to myeloma and if the duration of renal failure does not exceed two months * Patients must be 75 years of age or less at the time of registration * All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines. * If medically appropriate, patients with pathologic fractures, pneumonia at diagnosis or hyperviscosity with shortness of breath should have these conditions attended to prior to registration.
