Altogether, these findings suggest administering ibrutinib before leukapheresis may modify T-cell characteristics in the collected material, thereby improving final CAR T-cell product quality and clinical outcomes for patients with R/R LBLC treated with tisagenlecleucel. This trial was registered at www.clinicaltrials.gov as #NCT03876028.
Overall, FTO promotes DLBCL progression and ibrutinib resistance by demethylating Myc mRNA and stabilizing its expression. These findings highlight the FTO-m6A-Myc axis as a potential therapeutic target for overcoming drug resistance in DLBCL.
