Michel Delforge, MD, PhD, University of Leuven, Leuven, Belgium, discusses preliminary results from the phase Ib/II CARTITUDE-1 trial (NCT03548207), investigating the chimeric antigen receptor (CAR) T-cell therapy, ciltacabtagene autoleucel (cilta-cel), in relapsed/refractory (R/R) multiple myeloma. 97 patients with R/R myeloma received cilta-cel in this study, of which 87.6% were triple-refractory to their last line of therapy. The overall response rate was 94.8% with a stringent complete response rate of 55.7%. These results indicate that a single low-dose infusion of cilta-cel leads to early, deep, and durable responses in heavily pretreated multiple myeloma patients. Dr Delforge also discusses toxcities associated with CAR T-cell therapy. This interview took place during the 62nd American Society of Hematology (ASH) Annual Meeting and Exposition, 2020.
