idecabtagene vicleucel · BCMA CAR-TBCMA-specific IFN-γ release in vitro; CRS not modeled; expected depletion of normal plasma cells
Omisirge: which risks did reviewers probe?
omidubicel · Expanded cord blood HPC
Immune & cytokine safety
Not assessed nonclinically (immunodeficient model); clinically GvHD dose-safety relationship flat
“The dose-safety relationship is essentially flat suggesting that an increase in dose did not result in an increase in adverse events of interest such as aGvHD and cGvHD.”
Biodistribution & persistence
GLP mouse qPCR: human DNA in all tissues through Week 12, highest femur, spleen, lung, liver, kidney
“At Week 12, relatively high quantities of human DNA were found in femur, spleen, lung, liver, and kidney in the high dose group.”
Modality-specific risk
Genomic instability/tumorigenicity of ex vivo expanded HPCs; engraftment efficacy
“This study indicates that the CF manufacturing procedure, including NAM culture, does not appear to generate chromosomal abnormalities in the regions analyzed when compared to unmanipulated UCB.”
