This study is a multiple cohort, multicenter, open-label Phase 1 study with dose-escalation substudies investigating intravenous (IV) BAL0891 as monotherapy, and in combination with tislelizumab or paclitaxel, to determine the safety and tolerability of increasing doses of BAL0891 in patients with advanced solid tumors or relapsed or refractory acute myeloid leukemia. An adaptive model-based design will be used to guide the dose escalation. Subject assignment to Substudy 1, 2, 3 and 4 will be finalized following approval from the investigator and sponsor.
The dose-expansion stage will be conducted with the RP2D to further evaluate the preliminary anti-tumor activity, safety, and tolerability in metastatic TNBC and GC.
Informed consent signed by the patient prior to any study-related procedure indicating that they understand the purpose of, and procedures required for, the study, and are willing to participate in the study.
