    Intraperitoneal administration of carcinoembryonic antigen-directed chimeric antigen receptor T cells is a robust delivery route for effective treatment of peritoneal carcinomatosis from colorectal cancer in pre-clinical study. (PubMed, Cytotherapy)
    Taken together, our data suggest that i.p. administration of CAR T cells may be a robust delivery route for effective treatment of cancer.

    EVEREST-1: A seamless phase 1/2 study of CEA logic-gated Tmod CAR T-cell therapy (A2B530) in patients with solid tumors associated with CEA expression also exhibiting HLA loss of heterozygosity (LOH) (SITC 2023)
    The primary objective of phase 1 is to evaluate the safety and tolerability of A2B530 in patients with NSCLC, CRC, and PANC, and to identify the maximum tolerated dose and recommended phase 2 dose (RP2D). The dose-expansion phase will confirm RP2D and collect biomarker data to further characterize A2B530.

    BASECAMP-1: A master prescreening study to identify patients with high-risk or metastatic solid tumors with HLA loss of heterozygosity (LOH) in preparation for Tmod CAR T-cell therapy trials (SITC 2023)
    BASECAMP-1 is an ongoing prescreening study to: 1) Identify patients with tumor-associated HLA LOH and eligible for Tmod CAR T-cell therapy, and 2) Obtain leukapheresis in preparation for the autologous CAR T-cell therapy trials EVEREST-1 (A2B530 targeting carcinoembryonic antigen; NCT05736731) and EVEREST-2 (A2B694 targeting mesothelin). We have identified 52 patients across sites with study-specific disease types with HLA-A*02:01 LOH; of these, 13 are currently being screened, 23 have been found ineligible, and 16 have consented. This demonstrated the feasibility of leveraging a diagnostic during routine clinical workup to identify rare, molecularly defined patients for personalized clinical studies.

    Tumor Growth Suppression of Pancreatic Cancer Orthotopic Xenograft Model by CEA-Targeting CAR-T Cells. (PubMed, Cancers (Basel))
    Thus, the therapeutic effect of CAR-T therapy was related to the target antigen expression level, and the further retrospective analysis of pathological findings from PDAC patients showed a correlation between the intensity of CEA immunostaining and tumor heterogeneity. Therefore, CEA expression levels in biopsies or surgical specimens can be clinically used as biomarkers to select PDAC patients for anti-CAR-T therapy.
