progression, OS 5-10 years

17p- disease in MM
• 9-10% at presentation
• Progression event
• Associated with Light chain only disease, high
ISS stage
• Prognostic only if in ≥50% plasma cells
• Very poor outlook
• IFM study of Vel/Dex, EFS 14 mo vs 36mo
(A) Event-free survival (EFS) and (B) overall survival (OS) in patients with del(17p) (n = 54) or
without del(17p) (n = 453) treated with bortezomib-dexamethasone induction (EFS and OS in
years; P < .001 for EFS and OS).

Clinical trial
Clinical trials for relapsed MM
• Bortezomib trials (± HDACi, ±hsp90i,
±mAb)
– Usually IV velcade
– 1-3 prior lines
• Lenalidomide trials (±carfilzomib, ±CS1
mAb)
• Pomalidomide trials
• MUK Clinical Trials Network early phase
studies
– Less restriction in no of prior lines
