NCIt definition : A preparation of autologous tumor-infiltrating lymphocytes (TILs) derived from a patient's
tumor that have been treated ex vivo during cell expansion with NX-0255, an inhibitor
of Casitas B-lineage lymphoma proto-oncogene-b (CBL-B), with potential immunomodulating
and antineoplastic activities. Upon administration, the CBL-B inhibitor-treated autologous
TILs DeTIL-0255 specifically recognize and kill the patient's tumor cells. NX-0255
enhances TIL expansion and the tumor-killing ability of the TILs when returned to
the patient.;
