Catamaran Bio to Present Preclinical Data at ASGCT Annual Meeting to Support CAR-NK Approach for Solid Tumors

Two posters describe features of Catamaran’s CAR-NK platform designed to overcome the immunosuppressive effects of the solid tumor microenvironment

CAMBRIDGE, Mass. – May 2, 2022 – Catamaran Bio, Inc., a biotechnology company developing off‑the-shelf chimeric antigen receptor (CAR)-NK cell therapies to treat cancer, today announced that the company will present two posters at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting, being held in Washington, DC, on May 16-18, 2022. Catamaran scientists will present data supporting CAR‑NK cell therapy design strategies to neutralize the immunosuppressive effects of the tumor microenvironment, including use of synthetic biology-enabled chimeric switch receptors which convert the inhibitory signal of TGF-β into positive NK cell activation signals.

“We look forward to sharing our progress in engineering CAR-NK cells to confer them with the functional attributes to enable durable efficacy in solid tumors,” said Vipin Suri, PhD, MBA, Chief Scientific Officer of Catamaran Bio. “Our presentations at ASGCT describe approaches to mitigate the effects of TGF-β, a highly immunosuppressive cytokine known to reduce the anti-tumor activity of immune cells. We will show data on the activities of multiple TGF-β based synthetic receptors that confer a range of benefits to CAR-NK cells and enhance anti-tumor activity in high TGF-β environments.”

Details of the poster presentations are as follows:
