What the company doesAI summary of filing

GT Biopharma is a clinical-stage biopharmaceutical company developing immune-oncology products based on proprietary Tri-specific Killer Engager (TriKE) and Dual Targeting TriKE technology platforms. The company's therapeutics are designed to activate patients' natural killer cells to target and kill cancer cells expressing specific antigens such as CD33, B7-H3, and CD19, and potentially to treat autoimmune disorders. GT Biopharma does not currently generate revenue and relies on third-party contract manufacturers for production of its product candidates. The company has multiple product candidates in development: GTB-3650 targeting CD33+ acute myeloid leukemia and myelodysplastic syndromes (enrollment began January 2025), GTB-5550 targeting B7-H3+ solid tumors (anticipated enrollment mid-2026), and GTB-7550 for autoimmune disorders in preclinical development.
