✦ Synopsis
A 4-day continuous intravenous (CIV) infusion of vincristine and doxorubicin with highdose dexamethasone (VAD) regimen is a standard refractory multiple myeloma (MM) regimen. A Phase II study of a CEVAD regimen, i.e., VAD plus etoposide administered as a 96-hr continuous infusion, was carried out with IV bolus cyclophosphamide. Thirty-six patients were treated on study and received a total of 114 cycles of CEVAD: median 2 cycles (range 1-8). No patient achieved a CR. The overall rate of PR was 15/36 (42%). Patients achieved maximal response after a median of 4 (range 3-6) courses. PR rates were 40% (4/10) in patients with primary refractory disease, 48% (11/23) in patients with secondary refractory disease, 31% (6/19) in patients who had failed previous VAD therapy, and 50% (7/14) in patients receiving 2nd or subsequent relapse therapy. Three patients died during their initial cycle of therapy from rapidly progressive disease and sepsis. Overall median survival was 24 weeks with a 1-year survival of 33.3% {95% confidence interval of 20-46%}. Myelosuppression was the most frequent adverse event with NCI grade 2 neutropenia and/or thrombocytopenia in 15% of first cycles, grade 3 in 20%, and grade 4 in 65%. Two-thirds of patients had at least one episode of grade 3 or 4 sepsis. In 15% of septic episodes positive blood cultures were obtained. Overt cardiotoxicity was seen in two patients. CEVAD as used in this study was not more effective than VAD in terms of overall response rate or survival. Am.
