Dose Escalation Study of GCC19CART CoupledCAR ® Technology for Patients with Relapsed or Refractory Colorectal Cancer

Background: Chimeric antigen receptor (CAR) T-cell therapy has shown remarkable clinical efficacy in hematologic malignancies but limited success in solid tumors. GCC19CART, the first clinical candidate from the CoupledCAR ® solid tumor platform, targets guanylate cyclase-C (GCC) which is expressed in colorectal cancers. A Phase 1 investigator-initiated dose escalation trial is underway in China for patients with relapsed or refractory metastatic colorectal cancer. Data presented here are from a single participating institution.
