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 Study Slide Courtesy Niesvizky, R; ASH 2013
RESULTS Patients 502 patients were randomized to –VD (n=168), –VTD (n=167), –VMP (n=167) Baseline characteristics were well balanced across the treatment arms –Median age was 73 years (range 38–91) –48% of patients had comorbidities at baseline The most common were diabetes mellitus (21%), renal disease (15%), and chronic pulmonary disease (8%) Slide Courtesy Niesvizky, R; ASH 2013
Response* ORRs after 13 cycles were 73% (VD), 80% (VTD), and 70% (VMP) including: –30%, 40%, and 32% CR/nCR, respectively –37%, 51%, and 41% ≥VGPR, respectively *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) Best confirmed response after 8 (induction) and 13 (induction + maintenance) cycles Slide Courtesy Niesvizky, R; ASH 2013
PFS (intent-to-treat population) After a median follow-up of 42.7 months, 265 (53%) patients had progressed and/or died Median 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
OS (intent-to-treat population) Median OS (95% CI) was 49.8 months (35.7, not estimable [NE]), 51.5 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
UPFRONT TRIAL CONCLUSIONS After ~3.5 years’ follow-up, no significant differences in PFS or OS were seen among arms VTD had the highest toxicity rates and the lowest mean bortezomib dose intensity among the arms VD 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.
