TGRX-678 = Chinese Phase I in Chronic Myelogenous Leukemia (CML) Patients [China]

Study title

Chinese Phase I in Chronic Myelogenous Leukemia (CML) Patients

Scientific title

A Single-arm, Open-label, Dose Escalation and Dose Expansion Phase 1 Trial to Determine the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of TGRX-678 in Patients With Refractory or Advanced CML

Type of study

Trial after therapy failure or intolerance



Current status


Other trial ID NCT05434312

What is the purpose of the study

This is a study to evaluate the safety, tolerability and preliminary efficacy of TGRX-678 in patients with CML who had failure with or are intolerant to tyrosine kinase inhibitors (TKI). The study also assesses how the body interacts with TGRX-678. In scientific terms, this is called pharmacokinetics.

What will happen during the study

This is the first trial to investigate TGRX-678 in humans.

TGRX-678 is a new drug under investigation for the treatment of CML. TGRX-678 will be given as tablets. The dose will be escalated to determine the recommended dose for further clinical evaluation in patients with chronic phase CML.
