NCIt definition : A preparation of autologous tumor infiltrating lymphocytes (TILs) activated by an
anti-programmed cell death protein 1 (PD1) antibody, with potential immunomodulating
activity. The autologous TILs are isolated from an autologous tumor sample and ex-vivo
activated in the presence of anti-PD-1 antibody. Upon infusion of the autologous anti-PD1
antibody-activated TILs back into the patient, the cells specifically target and kill
the patient's tumor cells.;
