Abstract Background: High-dose melphalan (HDM) is the standard therapy for autologous stem cell transplantation (ASCT) in multiple myeloma (MM), although the optimal conditioning regimen remains yet to be identified. Bendamustine (BENDA) has a proved activity in hematological malignancies including both first line and relapsed MM. Methods: We conducted a phase II trial, adding BENDA to HDM before second ASCT, in a tandem ASCT strategy, in 32 patients with "de-novo" MM. All patients received a bortezomib-based induction therapy. High-dose cyclophosphamide (CY) and G-CSF were used to mobilize stem cells. Four to 6 weeks after the administration of CY, patients received HDM (200 mg/mq), followed by ASCT. Three to 6 months after the first transplantation, patients received a second ASCT with BENDA (200 mg/m2) to HDM (140 mg/m2) as conditioning regimen (BM). Results: The median age was 56 years (range 40 to 66). Overall, there was no transplant related mortality. The incidence of neutropenic fever and mucositis (grade 1-2) was 46.9% and 81.2%, respectively. No mucositis grade 3-4 was observed. Median number of days to neutrophil and platelet engraftment were 11 and 12, respectively. After the second transplantation, the complete response (CR) improved to 62.5%. Overall response rate was 90.6%. After a median follow-up of 18,2 months, 4 patients had progressed and 1 died. Median progression free survival (PFS) was not reached and actuarial 2-year PFS and OS was 78% and 90%, respectively. Conclusion: Bendamustine plus melphalan is feasible as conditioning regimen for second ASCT in MM and should be explored for efficacy in a phase III study. Longer follow-up is needed to evaluate conversion rate and survival. Disclosures No relevant conflicts of interest to declare.

Background Autologous hematopoietic stem cell transplantation (AHSCT) remains the standard of care for younger patients with multiple myeloma (MM). Currently, high-dose melphalan (HDM) is recommended as conditioning regimen before AHSCT. Preclinical data suggest that combining bortezomib and melphalan has synergistic effect against multiple myeloma cells. Bortezomib and HDM (Bor-HDM) combination as conditioning regimen has been investigated by many other investigators. Objective In this retrospective study, we aimed to compare transplant-related toxicities and hematologic recovery of HDM and Bor-HDM conditioning regimens. Method We retrospectively evaluated hematologic recovery and toxicity profile in patients with MM who received AHSCT with either HDM ( n = 114) or Bor-HDM ( n = 53) conditioning regimen. Results Nonhematologic toxicities were comparable between HDM and Bor-HDM conditioning regimen, except mucositis and diarrhea being more frequent in the Bor-HDM group. Neutrophil and platelet engraftment time and duration of hospital stay were significantly shorter for HDM regimen. Conclusions In this retrospective analysis, we observed engraftment kinetics and duration of hospitalization were significantly worse in Bor-HDM conditioning regimen with manageable toxicities. Randomized studies are needed to further compare Bor- HDM regimen to HDM in terms of response rates, toxicities, and transplant-related mortality.
