Efficacy of Dendritic Cell Therapy for Myeloid Leukemia and Myeloma

Summary

Dendritic cell therapy is a promising strategy for adjuvant cancer therapy in the setting of minimal residual disease (MRD) to fight off cancer relapse and/or progression. The investigators already performed a phase I safety study in leukemia patients that were in complete remission demonstrating the absence of side effects and feasibility of the therapy. Here, the investigators want to extend on this strategy by studying the clinical efficacy of autologous DC vaccination in patients with acute and chronic myeloid leukemia and myeloma patients. Effects of DC therapy on the immune reactivity towards leukemia cells as well as clinical parameters such molecular MRD monitoring, time to relapse (TTR), progression-free survival (PFS) and overall survival(OS) will be studied in vaccinated and non-vaccinated (control) patients. Patients will be vaccinated using their own dendritic cells electroporated with mRNA coding for the full-length Wilms' tumor antigen WT1.
