St. Jude Reference #SJ-22-0015
Researchers at St Jude identified proteins that help decide T cell fate and used that finding to improve CAR-T cell therapy in a solid tumor model. The improvement comprises inhibition of Arid1a (a component of the BAF complex) to increase persistence of CAR-T cells in patients, leading to a more durable response. This represents a generic improvement that can be used to increase the efficacy of any CAR-T cell therapy.
A Nature publication describing this finding that transient inhibition of Arid1a with RBD-K98645985 during CAR-T cell generation promote memory function and improve tumor control published June 22, 2022.
