Bortezomib, Lenalidomide, Thalidomide, Doxil, Carfilzomib, Pomalidamide Target MM in the BM microenvironment to overcome conventional drug resistance in vitro and in vivo Effective in relapsed/refractory, relapsed MM and now part of induction, consolidation, and maintenance therapy Nine FDA approvals in the last decade and median survival prolonged from 2-3 yrs to at least 5-7 yrs, with additional prolongation seen from maintenance New approaches needed to treat and ultimately prevent relapse Integration of Novel Therapy Into Myeloma Management

Results Richardson et al, ASH 2013
Phase I MTD • Cohort level 1 (carfilzomib 27 mg/m2, pomalidomide 4 mg, dexamethasone 40 mg): 1 of 6 patients experienced a dose-limiting toxicity (DLT) of febrile neutropenia • Cohort level 2 (carfilzomib 36 mg/m2, pomalidomide 4 mg, dexamethasone 40 mg): 2 of 6 patients experienced DLTs consisting of grade 4 thrombocytopenia and grade 3 rash • The MTD was established as carfilzomib 27 mg/m2, pomalidomide 4 mg, dexamethasone 40 mg Shah et al ASH 2013

Conclusions • The combination of Car-Pom-d is highly active in this heavily pretreated, lenalidomide-refractory patient population • Patients had received a median of 5 prior lines of therapy; 49% of patients had high/intermediate risk cytogenetics at baseline • Response rates, PFS, and OS were preserved independent of FISH/cytogenetic risk status • The regimen was well tolerated with no unexpected toxicities • Enrollment is nearly complete in this phase II trial; subsequent dose escalation of carfilzomib in less heavily treated patients with 1−3 lines of prior therapy is planned • ≥ VGPR 27% • ORR 70% • CBR 83% • DOR (median) 17.7 months • PFS (median) 9.7 months • OS (median) > 18 months Shah et al ASH 2013
