Of the 13 286 autologous haematopoietic cell transplant procedures reported in the US in 2010-2012 for plasma cell disorders, 10 557 used single agent, high-dose melphalan. Despite 30 years of clinical and pharmacokinetic ( PK) experience with high-dose melphalan, and its continuing central role as cytoreductive therapy for large numbers of patients with myeloma, the pharmacodynamics and pharmacogenomics of melphalan are still in their infancy. The addition of protectant agents such as amifostine and palifermin allows dose escalation to 280 mg/m(2), but at these doses it is cardiac, rather than gut, toxicity that is dose-limiting. Although combination with additional alkylating agents is feasible, the additional TRM may not be justified when so many post-consolidation therapies are available for myeloma patients. Current research should optimise the delivery of this single-agent chemotherapy. This includes the use of newer formulations and real-time PKs. These strategies may allow a safe and effective platform for adding synergistic novel therapies and provide a window of lymphodepletion for the addition of immunotherapies.
