An open-label phase I/II study of cyclophosphamide, bortezomib, pegylated liposomal doxorubicin, and dexamethasone in newly diagnosed myeloma.


ABSTRACT: We conducted a phase 1/2 trial evaluating the combination of cyclophosphamide, bortezomib, pegylated liposomal doxorubicin, and dexamethasone (CVDD) for newly diagnosed multiple myeloma (MM). The primary objective of the phase 1 was to evaluate the safety and tolerability of maximum planned dose (MPD) and the phase 2 was to assess the overall response rate. Patients received 6-8 cycles of CVDD at four dose levels. There were no dose-limiting toxicities. The MPD was cyclophosphamide 750 mg/m(2) IV on day 1, bortezomib 1.3 mg/m(2) IV on days 1, 4, 8, 11, pegylated liposomal doxorubicin 30 mg/m(2) IV on day 4, and dexamethasone 20 mg orally on the day of and after bortezomib (21-d cycle). Forty-nine patients were treated at the MPD of which 22% had high-risk myeloma. The most common grade ?3 toxicities included myelosuppression, infection, and fatigue. Overall response and complete response rates were 91% and 26% in standard-risk, and 100% and 58% in high-risk cohort, respectively. After a median follow-up of 34 months, the median progression-free survival was 31.3 months. The 2-yr overall survival was 91.1% in the standard-risk and 88.9% in the high-risk cohort, respectively. CVDD regimen was well tolerated and was highly active in newly diagnosed MM.
