OncLive spoke with Larry Anderson, MD, PhD, associate professor, Department of Internal Medicine, Division of Hematology/Oncology, Harold C. Simmons Comprehensive Cancer Center, UT Southwestern Medical Center, about the methods utilized in the phase 2 KarMMa trial (NCT03361748) in multiple myeloma (MM).

The KarMMa trial investigated the efficacy and safety of idecabtagene vicleucel (ide-cel; Abecma) in patients with relapsed/refractory MM. Updated data was presented at the 2021 International Myeloma Workshop.

Prior to ide-cel administration, peripheral blood autologous T cells are taken via leukapheresis from a patient and modified with a viral vector to express a CAR T-cell receptor that recognizes BCMA, a plasma cell–specific surface protein on myeloma cells that is not expressed on other normal tissue, Anderson explains. In the KarMMa trial, 128 patients with relapsed/refractory multiple myeloma who received at least 3 prior lines of therapy were treated with ide-cel across a target dose range of 150 x 106 to 450 x 106 CAR T cells, Anderson adds. Patients had received a median of 6 prior lines of therapy, with a range from 3 to 16, Anderson concludes.
