NCIt definition : A preparation of autologous, epigenetically reprogrammed, polyclonal tumor infiltrating
lymphocytes (TILs), with potential immunomodulating and antineoplastic activities.
The autologous TILs LYL845 are prepared and expanded ex vivo by co-culturing autologous
tumor cells with specific Epi-R cell culture media containing optimized cytokine composition
and cell activation which creates TILs enriched with CD8-positive T-cells with diverse
tumor-reactive clones and an enhanced proportion of stem-like T-cells. Upon administration,
the autologous TILs LYL845 may target and kill tumor cells and secrete pro-inflammatory
cytokines. LYL845 shows increased durability of expanded TILs, enhanced polyclonality
and increased tumor-reactive cytolytic T-cells compared to TILs derived from the standard
process.;
