abstract = {CAR T cells are genetically modified T cells that target
specific epitopes. CAR T cell therapy has proven effective
in difficult-to-treat B cell cancers and is now expanding
into hematology and solid tumors. To date, approved CAR
therapies target only two specific epitopes on cancer cells.
Identifying more suitable targets is challenged by the lack
of truly cancer-specific structures and the potential for
on-target off-tumor toxicity. We analyzed gene expression of
potential targets in single-cell data from cancer and
healthy tissues. Because safety and efficacy can ultimately
only be defined clinically, we selected approved and
investigational targets for which clinical trail data are
available. We generated atlases using >300,000 cells from 48
patients with follicular lymphoma, multiple myeloma, and
B-cell acute lymphoblastic leukemia, and integrated over 3
million cells from 35 healthy tissues, harmonizing datasets
from over 300 donors. To contextualize findings, we compared
target expression patterns with outcome data from clinical
trials, linking target profiles to efficacy and toxicity,
and ranked 15 investigational targets based on their
similarity to approved ones. Target expression did not
significantly correlate with reported clinical toxicities in
patients undergoing therapy. This may be attributed to the
intricate interplay of patient-specific variables, the
limited amount of metadata, and the complexity underlying
toxicity. Nevertheless, our study serves as a resource for
retrospective and prospective target evaluation to improve
the safety and efficacy of CAR therapies.},
