This is the first-in-human trial with TGRX-678 which aims to evaluate the safety profile and preliminary efficacy profile in advanced or refractory CML patients with previous failure or intolerence to TKI treatments. The primary purpose of this study is to evaluate the safety profile of TGRX-678, including determination of the maximal tolerated dose (MTD) and recommended phase II dose (RP2D), and other safety measures of the investigational drug, such as adverse events and abnormal clinical outcomes. Preliminary efficacy profile of TGRX-678 is evaluated based on the changes in peripheral blood cells and disease-associated cytogenetic markers. The safety, tolerability and efficacy profiles, along with pharmacokinetic analysis, will be assessed together to determine the optimal dose for expansion.
