Description
Preclinical and clinical studies have demonstrated synergy between bortezomib and pegylated liposomal doxorubicin (PLD) for relapsed/refractory (R/R) multiple myeloma (MM) patients compared to bortezomib as a single agent. This retrospective study evaluated the efficacy and safety of a more frequent lowdose schedule of PLD, bortezomib, and intravenous dexamethasone (DVD) for patients with R/R MM, many of whom were previously treated with bortezomib. Twenty-eight patients with R/R MM were treated, and 23 (83%) had been previously treated with .1 bortezomib-containing regimen. Treatment consisted of dexamethasone 40 mg intravenously, bortezomib 1.0 mg/ m2, and PLD 5.0 mg/m2 on days 1, 4, 8, and 11 of a 28- day cycle for a maximum of eight cycles. Patients ranged from 33 to 81 years of age (median, 67) and had received 1.14 prior therapies (median, 5). At baseline, ten, nine, and nine patients were in stages I, II, and III, respectively, as defined by the International Staging System, and eight (29%) patients had elevated serum creatinine levels. The overall response rate was 61%, which included one (4%) complete response, three (11%) very good partial responses, eight (29%) partial responses, and five (18%) minimal responses. Of the 23 patients who had previously received bortezomib, 12 (52%) responded. The regimen was well tolerated with only six patients (21%) who showed worsening of their baseline peripheral neuropathy (PN). One patient discontinued this regimen due to an adverse event (grade II PN). DVD appears to represent a well-tolerated regimen with a high response rate for the treatment of R/R MM patients.
