15 Efficacy and Safety of Three Bortezomib-Based Induction and Maintenance Regimens in Previously Untreated, Transplant-Ineligible Multiple Myeloma Patients: Final Results from the Randomized, Phase 3b, US Community-Based UPFRONT StudySlide Courtesy Niesvizky, R; ASH 2013
16 RESULTS Patients 502 patients were randomized to VD (n=168),VTD (n=167),VMP (n=167)Baseline characteristics were well balanced across the treatment armsMedian age was 73 years (range 38–91)48% of patients had comorbidities at baselineThe most common were diabetes mellitus (21%), renal disease (15%), and chronic pulmonary disease (8%)Slide Courtesy Niesvizky, R; ASH 2013
17 Response*ORRs after 13 cycles were 73% (VD), 80% (VTD), and 70% (VMP) including:30%, 40%, and 32% CR/nCR, respectively37%, 51%, and 41% ≥VGPR, respectivelyBest confirmed response after 8 (induction) and 13 (induction + maintenance) cycles*Response-evaluable population (n=425 patients who received at least one dose of study drug, had measurable disease at baseline, and had at least one post-baseline M-protein measurement)Slide Courtesy Niesvizky, R; ASH 2013
18 PFS (intent-to-treat population) After a median follow-up of 42.7 months, 265 (53%) patients had progressed and/or diedMedian PFS (95% CI) was 14.7 months (12.0, 18.6), 15.4 months (12.6, 24.2), and 17.3 months (14.8, 20.3), for VD, VTD, and VMP, respectively, with no global difference among arms (p=0.458)Slide Courtesy Niesvizky, R; ASH 2013
19 OS (intent-to-treat population) Median OS (95% CI) was 49.8 months (35.7, not estimable [NE]), months (38.5, NE), and 53.1 months (41.1, NE) for VD, VTD, and VMP, respectively, with no global difference among arms (p=0.789)Slide Courtesy Niesvizky, R; ASH 2013
20 UPFRONT TRIAL CONCLUSIONS After ~3.5 years’ follow-up, no significant differences in PFS or OS were seen among armsVTD had the highest toxicity rates and the lowest mean bortezomib dose intensity among the armsVD doublet therapy may be as effective as VTD or VMP triplet therapy in elderly pat (due less toxicity with higher bortezomib intensity?)In accordance with:Recent analysis of VMP data from VISTA suggests that a higher cumulative bortezomib dose, reflecting prolonged treatment duration and/or dose intensity, is associated with superior OS (Mateos MV, et al.
