abstract = {Genomic profiling revealed the identity of at least 5
subtypes of diffuse large B-cell lymphoma (DLBCL), including
the MCD/C5 cluster characterized by aberrations in MYD88,
BCL2, PRDM1, and/or SPIB. We generated mouse models
harboring B cell-specific Prdm1 or Spib aberrations on the
background of oncogenic Myd88 and Bcl2 lesions. We deployed
whole-exome sequencing, transcriptome, flow-cytometry, and
mass cytometry analyses to demonstrate that Prdm1- or
Spib-altered lymphomas display molecular features consistent
with prememory B cells and light-zone B cells, whereas
lymphomas lacking these alterations were enriched for late
light-zone and plasmablast-associated gene sets. Consistent
with the phenotypic evidence for increased B cell receptor
signaling activity in Prdm1-altered lymphomas, we
demonstrate that combined BTK/BCL2 inhibition displays
therapeutic activity in mice and in five of six
relapsed/refractory DLBCL patients. Moreover, Prdm1-altered
lymphomas were immunogenic upon transplantation into
immuno-competent hosts, displayed an actionable PD-L1
surface expression, and were sensitive to
antimurine-CD19-CAR-T cell therapy, in
vivo.Relapsed/refractory DLBCL remains a major medical
challenge, and most of these patients succumb to their
disease. Here, we generated mouse models, faithfully
recapitulating the biology of MYD88-driven human DLBCL.
These models revealed robust preclinical activity of
combined BTK/BCL2 inhibition. We confirmed activity of this
regimen in pretreated non-GCB-DLBCL patients. See related
commentary by Leveille et al., p. 8. This article is
highlighted in the In This Issue feature, p. 1.},
