Measurable residual disease detection after CAR-T may predict response in patients with large B-cell lymphoma.

Abstract

Despite responses of chimeric antigen receptor (CAR)-T cells in patients with relapsed/refractory large B-cell lymphoma (LBCL), over half of patients eventually relapse. Methods to detect early disease persistence are needed to identify patients at high risk of treatment failure. We recently developed MAESTRO, an ultrasensitive, tumor-informed measurable residual disease (MRD) assay, which can detect parts-per-million (ppm) levels of circulating tumor DNA (ctDNA) using minimal sequencing. We applied MAESTRO to 140 samples from 28 patients (15 durable responders at 12 months and 13 nonresponders) to identify treatment failure after axicabtagene ciloleucel (axi-cel), administered at our institution between 2018 and 2022. Responder and nonresponder patients had similar baseli
