IFM 2005-01: Velcade/Dexamethasone Versus Vincristine/Adriamycin (Doxorubicin)/Dexamethasone (VAD) for the Treatment of Patients With Multiple Myeloma

After their written informed consent has been obtained and their eligibility verified, patients are randomised between 4 treatment arms: A1 VAD (4 cycles); A2 VAD (4 cycles) followed by DCEP (2 cycles); B1 Velcade® + dexamethasone (4 cycles); B2 Velcade® + dexamethasone (4 cycles) followed by DCEP (2 cycles) A1, A2, B1, B2 + autograft. Randomisation will be stratified on the basis of the initial b2 microglobulin level (> or < 3 mg/l) and the presence of chromosome 13 abnormalities identified by FISH analysis. VAD: Vincristine/Adriamycin/Dexamethasone; DCEP: Dexamethasone/Cyclophosphamide/ Etoposide/Cisplatin.
