Treatment With Olverembatinib in CML-CP Patients Who Failed to at Least Two Previously Administered Second-generation TKIs.

Treatment With Olverembatinib in Chronic Phase Chronic Myeloid Leukemia Patients Who Failed to at Least Two Previously Administered Second-generation Tyrosine Kinase Inhibitors: a Prospective, Single-arm Clinical Trial.

The purpose of this trial is to evaluate the efficacy and safety of olverembatinib(HQP1351) in patients with chronic myeloid leukemia in chronic phase (CML-CP) who are resistant and/or intolerant to at least two second-generation tyrosine kinase inhibitors. The efficacy of olverembatinib is determined by evaluating the major molecular responses(MMR) at the and of 12 months.

• Resistance and/or intolerance of at least two second-generation TKIs.
• Patients must sign an informed consent form (ICF) indicating they are aware of the investigational nature of this study, in keeping with the policies of the hospital.

Exclusion Criteria:

• Known to be allergic to study drug ingredients or their analogues.
