The poster presentation summarizes preclinical results of LGR5 CAR-T cells in two ovarian cancer models. The data shows that LGR5 CAR-T cells have significantly higher killing effects on OVCAR3 (an ovarian cancer cell line) and primary ovarian cancer cells compared to control T cells. In animal models, LGR5 CAR-T cells significantly decreased tumor burden. The data supports the conclusion that LGR5 CAR-T cells have potential to be developed as a novel immunotherapy for ovarian cancer.

"The data to be presented at Lorne Cancer 2023 regarding our lead LGR5 CAR-T cell therapy candidate provide further preclinical validation of our LGR5 CAR-T platform, supporting the effectiveness of LGR5 CAR-T in ovarian cancer models," said Deborah Rathjen, PhD, Carina’s Chief Executive Officer.

"Following the FDA green light on January 6 for our proposed clinical trial of our LGR5 CAR-T (CNA3103) in patients with metastatic colorectal cancer, we are working to initiate this trial as soon as possible. We are also encouraged by this latest data that suggests an additional indication for CNA3103" Dr Rathjen added.
