Details and patient eligibility

About

This study is an open-label, single arm phase 1b safety study of CAR2 Anti-CEA CAR-T cell hepatic arterial infusions for pancreatic carcinoma patients with carcinoembryonic antigen positive (CEA+) liver metastases resistant to standard therapy who meet all other eligibility criteria.

Full description

Patients will receive weekly 3 doses of CAR2 Anti-CEA CAR-T cells in each 28-day cycle by hepatic arterial infusions using a Pressure Enhanced Delivery Device (PEDD) with low dose systemic IL-2 support. Patients may receive up to 3 cycles of CAR2 Anti-CEA CAR-T cell hepatic arterial infusions, per discretion of the investigator.

All patients who receive investigational CAR-T therapy will be included in the analyses and summaries of safety, efficacy, pharmacokinetic, and pharmacodynamic assessments.

Has any clinically significant low baseline lab results for hemoglobin, platelet counts, and neutrophil counts at screening.
Has untreated or ongoing intra-abdominal infection or bowel obstruction.
Has any clinically significant elevated baseline lab results for serum creatinine, AST, and total bilirubin (except for patients in whom hyperbilirubinemia is attributed to Gilbert's syndrome), and alkaline phosphatase at screening regardless of causality.
Known HIV or acquired immunodeficiency syndrome-related illness, acute or history of chronic hepatitis B or C.
Female patients who are pregnant or breastfeeding.
Have active bacterial, viral, or fungal infections.
Has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent study participation.
