Phase III Randomized Trial of Thalidomide/Dexamethasone Versus Vincristine+Adriamycin+Dexamethasone (VAD)
Phase III Randomized Trial of Thalidomide/Dexamethasone Versus Vincristine+Adriamycin+Dexamethasone (VAD)
Investigators planned to accrue 176 participants, to compare the response rate, overall
 response rate and survival of patients with multiple myeloma (MM) when randomized to two
 regimens (thalidomide+Dexamethasone versus Vincristine+Adriamycin+Dexamethasone).
 Investigators also planned to test if treatment with zoledronate immediately prior to
 chemotherapy results in an enhanced response to treatment (i.e. increase in complete response
 rates).
Patients Randomized to receive VAD (vincristine, adriamycin, dexamethasone): All patients
 received four cycles of VAD repeated every 4 weeks. Chemotherapy was administered by
 continuous IV Infusion for 96 hours: vincristine at a dose of 0.4 mg/day and doxorubicin at a
 dose of 9 mg/m^2/day. Patients were administered dexamethasone 40 mg by mouth (PO) on days 1
 to 4, 9 to 12, and 17 to 20 of the initial two cycles. Dexamethasone was given only on days
 1-4 of all subsequent cycles. Patients were randomized to receive zoledronic acid IV on
 either Day 1 or 15 of each cycle. This schedule continued monthly as long as the patient
 remained on study. The dose was calculated based on the patients' monthly creatinine
 clearance. Upon initiation of Zometa therapy, the following guidelines were applied: For
 patients with creatinine clearance >60 mL/min, the recommended dose remained at 4mg. For
 patients with reduced creatinine clearance, dosing was calculated to achieve the same area
 under curve (AUC) as in patients with creatinine clearance of 75 mL/min. Creatinine clearance
 was calculated using the Cockcroft-Gault formula.
Inclusion Criteria:

 -  Patients must have newly diagnosed MM confirmed by the presence of bone marrow
 plasmacytosis with > 10 percent plasma cells, sheets of plasma cells, or biopsy-proven
 plasmacytoma. Patients must have Durie-Salmon Stage IIA-B or IIIA-B. Patients with
 non-secretory myeloma are eligible. (These patients will not be included in the
 analysis of response rates, but will be assessed for toxicity and survival).

 -  Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, 2, or 3

 -  ≥ 18 years of age.

 -  Signed informed consent form

 -  Expected survival of greater than 8 weeks

 -  Capable of swallowing study medication tablets

 -  Capable of following directions regarding taking study medication, or has a daily care
 provider who will be responsible for administering study medication.

 -  Patients will be eligible for study even if they lack socioeconomic access to
 autologous transplantation. (These patients will be identified prior to randomization
 so as not to confound study results).

 -  All patients (in the event that they are randomized to the thalidomide/dexamethasone
 arm) must agree to take part in the "System for Education and Prescribing Safety"
 (S.T.E.P.S.)™. They must sign a separate informed consent for this program.

 Exclusion Criteria:

 -  Elevated direct bilirubin > 2 mg/dl

 -  Serum alanine aminotransferase (ALT) or serum aspartate aminotransferase (AST) > 2
 times the upper limit of normal (ULN)

 -  Absolute neutrophil count (ANC) <1000/mL, unless felt to be secondary to myeloma

 -  Ongoing radiation therapy, or radiation therapy within 3 weeks prior to first
 treatment, unless the acute side effects associated with such therapy are resolved.

 -  Prior treatment for multiple myeloma

 -  Prior bisphosphonate use is allowed but they must be discontinued before starting
 treatment.

 -  Concurrent uncontrolled serious infection

 -  Patients with peripheral (sensory) neuropathy, grade 3 or higher

 -  Life-threatening illness (unrelated to tumor)

 -  History of any other ACTIVE and INVASIVE cancer other than the present condition
 (except non-melanoma skin cancer), unless in complete remission and off of all therapy
 for that disease for a minimum of 3 years.

 -  Women of childbearing potential (unless utilizing birth control) or who are pregnant
 or nursing will be excluded from this study.

 -  Patients with comorbid conditions that would contraindicate the use of vincristine,
 doxorubicin, dexamethasone, thalidomide, or zoledronate.

 -  Plasma Cell Leukemia
