Clinical Trial Summary

This is a multi-center Phase I/II clinical trial of GTB-3550 (CD16/IL-15/CD33) tri-specific killer cell engager (TriKE®) for the treatment of CD33-expressing high risk myelodysplastic syndromes, refractory/relapsed acute myeloid leukemia or advanced systemic mastocytosis. The hypothesis is that GTB-3550 TriKE® will induce natural killer cell function by targeting malignant cells as well as CD33+ myeloid derived suppressor cells (MDSC) which contribute to tumor induced immunosuppression. Because CD16 is the most potent activating receptor on natural killer (NK) cells, this single agent may induce a targeted anti-CD33+ tumor response.
