You can join if…

Open to people ages 18 years and up

  • Adults > 18 years old
  • Clinical and histopathological diagnosis of metastatic colorectal cancer
  • Guanylate Cyclase (GCC) positive disease as determined by immunohistochemistry (IHC). Positivity on staining of archival tumor tissue is adequate.
  • Limited liver disease (less than 7 lesions with largest lesion less than 3 cm)
  • No surgical options with curative intent.
  • Received prior therapy with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy in the advanced or metastatic setting, an anti-vascular endothelial growth factor (anti-VEGF) biological therapy if not contraindicated, and if RAS wild-type an anti-epidermal growth factor receptor (anti-EGFR) therapy in a manner consistent with National Comprehensive Cancer Network (NCCN) guidelines. Treatment must have been discontinued for disease progression or intolerance to therapy.
  • Have at least one extracranial measurable target lesions according to the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 standard.

You CAN'T join if...

  • Subjects with tumor lesion(s) in a location that may cause perforation of an organ or structure (such as the digestive track, urinary bladder, or blood vessel) with GCC19CART therapy.
  • No active infectious diseases or comorbid conditions that would interfere with safety or data quality.
  • Subjects with active infection requiring systemic therapy or causing fever (temperature > 38.1˚C) or subjects with unexplained fever (temperature > 38.1˚C) within 7 days prior to enrollment (leukapheresis) and reconfirmed prior to the day of investigational product administration.
