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
Best 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
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.

FIRST Trial: Conclusions
• Continuous Rd significantly extended PFS and OS vs. MPT
– PFS:
• HR= 0.72 (P= 0.00006)
• Consistent benefit across most subgroups
• Rd better than Rd18 (HR= 0.70, P= 0.00001)
• 3 yr PFS: 42% Rd vs 23% Rd18 and MPT
– Planned interim OS: HR= 0.78 (P= 0.0168)
– Rd was superior to MPT across all other efficacy secondary endpoints
• Safety profile with continuous Rd was manageable
– Hematological and non-hematological AEs were as expected for Rd and
MPT
– Incidence of hematological SPM was lower with continuous Rd vs. MPT
• In NDMM transplant-ineligible patients, the FIRST Trial establishes continuous
Rd as a new standard of care
