CONCLUSIONS REGARDING TT3 *
· Remarkably high protocol compliance
· Low TRM of 5%
· Marked efficacy:
­ n-CR, 80%; CR: 60%
­ at 24mo: OS, 87%; EFS, 84%; continuous CR, 91%
· GEP-defined low-risk (85%) v high-risk (15%):
­ at 24mo: OS, 91% v 70%; EFS, 90% v 58%;
continuous CR, 94% v 60%
­ GEP-risk overrides prognostic implications of t(4;14)
­ Down-regulation of microenvironment gene 48h after VEL test
dose associated with superior survival ­ implications for TT4?
· TT3 superior to TT2 (attributable to bortezomib?):
­ in GEP-defined low-risk disease (EFS, CR duration)
­ in t(4;14) subgroup (OS)
