autologous tumor-infiltrating lymphocytes GT307

A preparation of autologous tumor-infiltrating lymphocytes (TILs) derived from each patient's resected tumor and edited with the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated protein 9 (Cas9) system to eliminate the expression of as of yet not elucidated immunoregulatory targets, with potential immunomodulating and antineoplastic activities. Upon administration back into the patient, autologous TILs GT307 specifically recognize and kill the patient's tumor cells. The knockout of the immunoregulatory targets may enhance the proliferation and cytokine release of the TILs.
