2. Background VMP and MPT, which are standard therapies for elderly patients with newly diagnosed multiple myeloma (NDMM), induce about a 30% near-complete response/complete response rate, with a 35% discontinuation rate due to adverse events. Carfilzomib, an irreversible proteasome inhibitor, has shown significant activity and favorable toxicity in MM. Preliminary results with a combination of carfilzomib with cyclophosphamide and dexamethasone (CCd) showed encouraging activity in elderly patients with NDMM (Proc ASH 2012;Abstract 730). Study objective: To present updated efficacy and safety results with the CCd regimen after 8 months of follow-up for patients with symptomatic NDMM who are ≥65 years old or ineligible for autologous stem cell transplantation.

Author Conclusions CCd showed encouraging activity in elderly patients with NDMM in comparison to results with MPT and VMP from other studies. 1-3 –≥VGPR: 76% vs 36% (MPT) or 41% (VMP) –nCR/CR/sCR: 64% vs 27% (MPT) or 30%* (VMP) –sCR: 24% (not reported for MPT or VMP) The CCd combination was well tolerated. Grade 3 or 4 adverse events included –Thrombocytopenia: 4% vs 3% (MPT) or 37% (VMP) –Peripheral neuropathy: 0% vs 6% (MPT) or 14% (VMP) –Venous thromboembolic events: 0% vs 9% (MPT) or 1% (VMP) –Treatment discontinuation: 11% vs 35% (MPT) or 33% (VMP) Bringhen S et al.

10. Investigator Commentary: Initial Results of the Phase II Study of CCd for Patients with NDMM From this and several other studies, it is increasingly obvious that melphalan is much more toxic than dexamethasone and cyclophosphamide. Melphalan probably adds some benefit over cyclophosphamide and dexamethasone, but in continuous or maintenance therapy the advantages are limited and do not counterbalance the disadvantages of its toxicity. Cyclophosphamide is better tolerated than melphalan, including by patients older than 75 years. More importantly, this study showed that it is possible to double the rate of CR or nCR with CCd (64%) in comparison to the VMP regimen (30%). Patients achieved a stringent CR of 24% with CCd. As other studies have demonstrated, carfilzomib is well tolerated. When it was used in doses up to 36 mg/m 2 in patients older than 75, no major side effects were observed.
