Carina Biotech to Present Preclinical Data Evaluating LGR5-Targeted CAR-T Cell Therapy in Colorectal Cancer Models at 2023 AACR

  • Preclinical data demonstrates that LGR5-targeting CAR-T therapy has high potential as an effective therapeutic for human colorectal cancer.
  • LGR5-targeting CAR-T cells effectively kill LGR5-expressing cancer cells in in vitro assays.
  • The development of a flow cytometric assay that allows specific identification and quantitation of LGR5-targeting CAR-T cells will be presented.
  • Evidence that detection of LGR5 expression in cancer biopsies may be used to identify eligible colorectal (bowel) cancer patients for inclusion into the planned Phase1/2a clinical trial will also be presented.

ADELAIDE, Australia, March 21, 2023 (GLOBE NEWSWIRE) — Carina Biotech (Carina), a cell therapy immuno-oncology company, today announced four poster presentations from preclinical studies of its LGR5-targeting CAR-T platform in colorectal cancer at the 2023 American Association for Cancer Research (AACR) Annual Meeting that will take place in Orlando, Florida on April 14-19.

“We are looking forward to sharing preclinical data related to our LRG-5 targeted CAR-T platform in colorectal cancer at the upcoming 2023 AACR meeting. The data expand upon the preclinical evidence supporting our LGR5 CAR-T cell candidate CNA3013 and the planned Phase 1/2a clinical trial in patients with advanced colorectal cancer patients. This follows the greenlight for our CNA3103 Investigational New Drug (IND) application by the US Food and Drug Administration (FDA) in January 2023,” stated Deborah Rathjen, PhD, Carina’s Chief Executive Officer.

About Carina Biotech
Immuno-oncology company Carina Biotech is developing CAR-T and other adoptive cell therapies for the treatment of solid cancers. In addition to its LGR5-targeted CAR-T cell therapy CNA3103 for advanced colorectal cancer, Carina has a deep pipeline of CAR-T programs.
Using its proprietary chemokine receptor platform, Carina aims to improve access to and infiltration of solid cancers by CAR-containing cells, resulting in more potent and specific cancer killing and reduced off-target effects.

Carina also has a fully integrated, proprietary manufacturing process that has both reduced manufacturing time and improved CAR-T cell quality, capable of delivering robust “serial-killing” CAR-T cells to patients.
