Up to 63.7% reduction in bone marrow blast levels observed in some patients. GTB-3550 was well tolerated by all patients with no cytokine release syndrome observed. Restoration of patient's endogenous NK cell function, proliferation and immune surveillance observed in all patients – No progenitor-derived or autologous/allogenic cell therapy required.The on-going Phase 1 clinical trial of GTB-3550 TriKE™ monotherapy is focused on evaluating safety, and the determination of the recommended Phase 2 dose (RP2D), dose schedule and the maximum tolerated dose (MTD). Additional information is being collected concerning anti-tumor activity against CD33+ acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) cancer cells, and restoration of the patient's exhausted/inhibited endogenous NK cell population. To date, 11 patients have completed treatment in the GTB-3550 Phase 1 clinical trial. Patient 5, Patient 7, Patient 9, Patient 11 experienced 33%, 61%, 63% and 50% reduction in CD33+ AML/MDS bone marrow blast levels, respectively. The Phase 1 safety part of the study is expected to conclude in late August 2021 with data publication current...
