This technology is designed to harness and enhance the body’s natural killer (NK) cells by simultaneously binding tumor antigens and interleukin-15 (IL-15), stimulating NK cell proliferation and targeted cytotoxicity. By focusing on NK cell engagement rather than T-cell activation, the company aims to offer therapies with potentially improved safety profiles and reduced immune-related adverse events. The company’s lead candidate, GTB-3550, is currently in clinical trials for hematologic malignancies such as acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and myelodysplastic syndromes (MDS). Beyond GTB-3550, GT Biopharma is advancing a pipeline of preclinical TriKE constructs aimed at both hematologic and solid tumors, as well as exploring applications in infectious diseases. The modular nature of the TriKE platform enables rapid development of new molecules targeting diverse antigens, supporting strategic combination therapies and expansion into multiple oncology indications. Founded in 2015 with technology originally licensed from the National Institutes of Health, GT Biopharma is headquartered in Tempe, Arizona, and conducts research and development operations in the United States. The company collaborates with leading academic institutions and global clinical sites to advance its pipeline. Under the leadership of President and CEO Scott K. Koenig, GT Biopharma continues to pursue its mission of delivering next-generation cell-engaging therapies to improve outcomes for patients with cancer and beyond.AI Generated. May Contain Errors.
