CER T Cells in combination with PARP Inhibitors

CER T cells Synergize with PARPi to Kill Ovarian Tumor Cells

  • Tumor cell killing was enhanced by the combination of CER-1236 or CER-1234 T cells with niraparib or olaparib
  • wtTIM-4 T cells (no intracellular signaling domain) show no additive effect with niraparib or olaparib
  • CER-1236 and CER-1234 T cells alone exhibited limited cytotoxic activity
