About GT Biopharma, Inc.: GT Biopharma is a pharmaceutical company developing innovative drugs focused on the treatment of cancer and other unmet medical needs. Its lead drug candidate, OXS-1550 (DT2219ARL) is a novel bispecific scFv recombinant fusion protein-drug conjugate composed of the variable regions of the heavy and light chains of anti-CD19 and anti-CD22 antibodies and a diphtheria toxin as its cytotoxic drug payload. OXS-1550 targets and binds to cancer cells expressing the CD19 receptor or CD22 receptor or both receptors. When OXS-1550 binds to cancer cells, they internalize the drug and are killed due to the cytotoxic payload. OXS-1550 has demonstrated encouraging results in early human clinical trials in patients with relapsed/refractory B-cell lymphoma or leukemia. OXS-3550 TriKE technology was developed by researchers at the University of Minnesota Masonic Cancer Center. As demonstrated in non-clinical models, this targeted immunotherapy directs NK cells to kill cancer cells while diminishing the drug-related toxicity and is anticipated to be to NK cells what CAR-T is to T-cells. Additionally, GT Biopharma is focused on acquiring or discovering and patenting late-stage, de-risked, and close-to-market improved treatments for Central Nervous System disease and shepherding the products through the FDA approval process to the NDA. Its CNS products currently include treatment for neuropathic pain, refractory epilepsies, the symptoms of myasthenia gravis, and motion sickness.
