Abstract
Efficacy and safety of bortezomib-based consolidation following ASCT were investigated in newly diagnosed multiple myeloma patients from Australia, Korea, and China. Patients received three cycles of bortezomib-cyclophosphamide-dexamethasone induction followed by high-dose therapy/ASCT, then were randomized (1:1) to consolidation with TP (thalidomide 100 mg/d for ≤12 months/until disease progression; prednisolone 50 mg on alternate days indefinitely/until disease progression; n = 100) or VTP (subcutaneous bortezomib 1.3 mg/m2 every 2 weeks for 32 weeks, plus TP; n = 103). The hypothesized difference in CR + VGPR rate (after ≤12 months consolidation therapy) was not met. The rate of CR + VGPR was numerically higher with VTP versus TP; however, this was not statistically significant (85.7% versus 77.1%; rate difference 8.6%; 95% confidence interval −2.3%–19.5%; p =.122). Secondary efficacy outcomes were similar between treatment arms. Addition of bortezomib to TP consolidation was associated with limited additional toxicity but did not significantly improve efficacy versus TP. [ABSTRACT FROM AUTHOR]
