Patients were well balanced between both arms except for SR-aGvHD grade IV which was higher in the Ruxo-ECP group (45% vs. 14%, P<0.001). In both cohorts, steroids were tapered rapidly, and median steroid treatment was 39 days in Ruxo and 35 days in Ruxo-ECP. The overall response rate including complete remissions (CR) of aGvHD at day 28 was 90% and 31% for Ruxo versus 86% and 0% (P<0.001, respectively) for Ruxo-ECP.

We investigated the potential value of molecular measurable residual disease (MRD) on circulating tumor DNA (ctDNA) to predict the outcome of 73 DLBCL patients. At baseline, next-generation sequencing was used to detect clonal immunoglobulin (IG) gene rearrangements on tumor biopsies (N=57) and ctDNA (N=73). MRD monitoring was applied by tracking the IG clones in ctDNA samples collected during treatment (interim) and at the end of treatment (EOT). MRD results were correlated with clinical data and radiologic disease assessment. Before treatment, clonal IG were found in 91.2% (52/57) of tumor biopsies and in 93.2% (68/73) of ctDNA samples. In paired samples, the same clonotype was found in 69.2% (36/52) of cases. At the interim analysis, ctDNA MRD was negative in 32 of 45 evaluable patients and positive in 13 of 45, correlating significantly with progression-free survival (PFS) (78.1% MRD- vs. 30.8% MRD+; P<0.0001) after a median follow-up of 40 months. Moreover, ctDNA MRD could stratify prognosis of 27 patients in partial response (P=0.018). At EOT, ctDNA MRD was negative in 37 of 47 patients and positive in ten of 47 (PFS 83.8% MRD- vs. 0% MRD+; P<0.0001). All MRD+ patients in complete metabolic response relapsed (P<0.0001).
