2seventy bio is a clinical-stage biotechnology company focused on the discovery, development and manufacturing of engineered cell therapies for the treatment of cancer. The company’s proprietary platforms leverage both autologous and allogeneic approaches to address solid tumors and hematologic malignancies. Through a multi-modality pipeline, 2seventy bio aims to expand the reach of cell-based immunotherapies beyond current indications, harnessing T cell receptors (TCRs), chimeric antigen receptors (CARs) and natural killer (NK) cells.
The company’s lead programs include TCR-T cell candidates targeting well-characterized tumor antigens such as NY-ESO-1 and MAGE-A4, as well as next-generation CAR-T constructs designed to overcome tumor microenvironment barriers. In parallel, 2seventy bio is developing off-the-shelf NK cell therapies engineered for enhanced persistence and cytotoxicity. Its integrated manufacturing network supports both clinical supply and scalable commercial production, enabling efficient translation from discovery to late-stage trials.
