Purpose To evaluate the effect of bortezomib as induction therapy before autologous transplantation, followed by lenalidomide as consolidation-maintenance in myeloma patients. Patients and Methods Newly diagnosed patients age 65 to 75 years were eligible. Induction (bortezomib, doxorubicin, and dexamethasone [PAD]) included four 21-day cycles of bortezomib (1.3 mg/m(2) on days 1, 4, 8, and 11), pegylated liposomal doxorubicin (30 mg/m(2) on day 4), and dexamethasone (40 mg/d; cycle 1: days 1 to 4, 8 to 11, and 15 to 18; cycles 2 to 4: days 1 to 4). Autologous transplantation was tandem melphalan 100 mg/m(2) (MEL100) and stem-cell support. Consolidation included four 28-day cycles of lenalidomide (25 mg/d on days 1 to 21 every 28 days) plus prednisone (50 mg every other day), followed by maintenance with lenalidomide (LP-L; 10 mg/d on days 1 to 21) until relapse. Primary end points were safety (incidence of grade 3 to 4 adverse events [AEs]) and efficacy (response rate). Results A total of 102 patients were enrolled. In a per-protocol analysis, after PAD, 58% of patients had very good partial response (VGPR) or better, including 13% with complete response (CR); after MEL100, 82% of patients had at least VGPR and 38% had CR; and after LP-L, 86% of patients had at least VGPR and 66% had CR. After median follow-up time of 21 months, the 2-year progression-free survival rate was 69%, and the 2-year overall survival rate was 86%. During induction, treatment-related mortality was 3%; grade 3 to 4 AEs included thrombocytopenia (17%), neutropenia (10%), peripheral neuropathy (16%), and pneumonia (10%). During consolidation-maintenance, grade 3 to 4 AEs were neutropenia (16%), thrombocytopenia (6%), pneumonia (5%), and cutaneous rash (4%). Conclusion Bortezomib as induction before autologous transplantation, followed by lenalidomide as consolidation-maintenance, is an effective regimen.

Abstract
Purpose To evaluate the effect of bortezomib as induction therapy before autologous transplantation, followed by lenalidomide as consolidation-maintenance in myeloma patients. Patients and Methods Newly diagnosed patients age 65 to 75 years were eligible. Induction (bortezomib, doxorubicin, and dexamethasone [PAD]) included four 21-day cycles of bortezomib (1.3 mg/m(2) on days 1, 4, 8, and 11), pegylated liposomal doxorubicin (30 mg/m(2) on day 4), and dexamethasone (40 mg/d; cycle 1: days 1 to 4, 8 to 11, and 15 to 18; cycles 2 to 4: days 1 to 4). Autologous transplantation was tandem melphalan 100 mg/m(2) (MEL100) and stem-cell support. Consolidation included four 28-day cycles of lenalidomide (25 mg/d on days 1 to 21 every 28 days) plus prednisone (50 mg every other day), followed by maintenance with lenalidomide (LP-L; 10 mg/d on days 1 to 21) until relapse. Primary end points were safety (incidence of grade 3 to 4 adverse events [AEs]) and efficacy (response rate). Results A total of 102 patients were enrolled. In a per-protocol analysis, after PAD, 58% of patients had very good partial response (VGPR) or better, including 13% with complete response (CR); after MEL100, 82% of patients had at least VGPR and 38% had CR; and after LP-L, 86% of patients had at least VGPR and 66% had CR. After median follow-up time of 21 months, the 2-year progression-free survival rate was 69%, and the 2-year overall survival rate was 86%.
