About GTB-3550 Trispecific NK cell Engager (TriKE™)
GTB-3550 is the Company's first TriKE™ product candidate being initially developed for the treatment AML. GTB-3550 is a single-chain, tri-specific scFv recombinant fusion protein conjugate composed of the variable regions of the heavy and light chains of anti-CD16 and anti-CD33 antibodies and a modified form of IL-15. The natural killer (NK) cell stimulating cytokine human IL-15 portion of the molecule provides a self-sustaining signal that activates NK cells and enhances their ability to kill. The Company is currently in a clinical trial with GTB-3550 in CD33 positive leukemia for acute myeloid leukemia (AML), and is studying myelodysplastic syndrome (MDS), and other CD33+ hematopoietic malignancies along with other solid tumor candidates.
