Business Overview
GT Biopharma's lead product candidate, GTB-3650, is a CD33-targeted TriKE® that leverages NK cells to target and eliminate myeloid leukemia cells. The company is advancing GTB-3650 through preclinical studies and has filed an Investigational New Drug (IND) application with the FDA, with plans to initiate a clinical study targeting patients with relapsed/refractory acute myeloid leukemia (AML) and high-grade myelodysplastic syndromes (MDS) in the second half of 2024.
The company's pipeline also includes GTB-5550, a B7-H3-targeted TriKE® for the treatment of solid tumors. GT Biopharma has initiated preclinical studies for GTB-5550 and plans to file an IND in the late second half of 2024, with the goal of starting a clinical study targeting patients with B7-H3 positive solid tumors in the first half of 2025.
