CAMBRIDGE, Mass.--(BUSINESS WIRE)--Catamaran Bio, Inc., a biotechnology company developing off-the-shelf chimeric antigen receptor (CAR)-NK cell therapies to treat cancer, today announced preclinical data that demonstrate key capabilities of its TAILWINDTM platform being applied to develop CAT-248, an allogeneic CD70-targeted CAR-NK cell therapy. The data demonstrate successful engineering of a CD70 CAR-NK cell therapy that achieves cytotoxicity in vitro against various tumor cell lines. Using the integrated engineering and manufacturing capabilities of the TAILWIND platform, the data also show highly efficient non-viral delivery of a CAR targeting CD70 and knock out of endogenous CD70 in a single engineering step.
The data support advancement of CAT-248, Catamaran’s co-lead CAR-NK cell therapy candidate, which is directed against CD70, a tumor antigen that is highly expressed on certain types of cancers including renal cell carcinoma, glioma, pancreatic cancer, and acute myeloid leukemia. The results were presented at the 63rd Annual Meeting of the American Society of Hematology (ASH) being held in Atlanta from December 11-14, 2021.
“CD70 is a compelling target in several high unmet need solid tumors and hematologic malignancies and we are excited to support the advancement of CAT-248 as an effective therapy for CD70 expressing cancers,” said Alvin Shih, MD, MBA, Chief Executive Officer of Catamaran Bio. “These data further establish our TAILWIND platform as an industry-leading, highly versatile and scalable manufacturing platform for CAR-NK cell therapies, including complex products with multiple genome modifications.”
“Our ASH data demonstrate cutting-edge capabilities that are essential for both tumor-targeting design as well as scalable manufacturing of CAR-NK cell therapies,” said Vipin Suri, PhD, MBA, Chief Scientific Officer of Catamaran Bio. “Notably, we have now demonstrated a novel single-step engineering approach for simultaneously using a non-viral transposon system for CAR delivery in combination with CRISPR editing for gene knockout. Using our TAILWIND platform, we effectively integrate all the necessary properties to position our CAR-NK cells as allogeneic, off-the-shelf therapies for multiple cancers, especially solid tumors.”
Data presented in a poster titled, “Engineering CD70-Directed CAR-NK Cells for the Treatment of Hematological and Solid Malignancies,” describe experiments showing key capabilities of the TAILWINDTM platform and characterization of the CD70-targeted CAR-NK cells. Highlights from the poster include:
The studies presented at ASH are co-authored by Catamaran and its collaborators at the University of Minnesota. The poster presentation is available on Catamaran’s website.
