Abstract
The Intergroupe Francophone du Myelome conducted a randomized trial to compare bortezomib-dexamethasone (VD) as induction before high-dose therapy (HDT) and autologous stem cell transplantation (ASCT) to a combination consisting of reduced doses of bortezomib and thalidomide plus dexamethasone (vtD) in patients with multiple myeloma. Overall, a total of 199 patients were centrally randomly assigned to receive VD or vtD. After 4 cycles, the complete response (CR) rate was the same in both groups (13% in the vtD arm, 12% in the VD arm, P = .74). However, the CR plus very good partial response (VGPR) rate was significantly higher in the vtD arm (49% vs 36%, P = .05). After ASCT, the CR plus VGPR rate was significantly higher in the vtD arm (74% vs 58%, P = .02). The reduced doses of bortezomib and thalidomide translated into a reduced incidence of peripheral neuropathy (PN): grade ≥ 2 PN were reported in 34% in the VD arm versus 14% in the vtD arm (P = .001). vtD, including reduced doses of bortezomib and thalidomide, yields higher VGPR rates compared with VD and can be considered a new effective triplet combination before HDT/ASCT.
