A Pivotal Study of HQP1351 in Patients With Chronic Myeloid Leukemia in Chronic Phase
- Conditions
- Chronic Myeloid Leukemia, Chronic Phase
- Interventions
- Drug: Imatinib, Dasatinib or Nilotinib
- Registration Number
- NCT04126681
- Lead Sponsor
- Ascentage Pharma Group Inc.
- Brief Summary
The purpose of this study is to evaluate the efficacy of HQP1351 in patients with chronic myeloid leukemia in chronic phase (CML-CP) who are resistant and/or intolerant to first- and second-generation tyrosine kinase inhibitors. The efficacy of HQP1351 is determined by evaluating the subjects' event free survival (EFS).
- Detailed Description
This is a phase 2, randomized, open label, pivotal study to evaluate the efficacy and safety of HQP1351 in CML CP patients who are resistant and/or intolerant to first- and second-generation TKIs in China. A total of 141 CML CP patients will be included in this study. After screening, eligible subjects will be randomized by 2:1 ratio to enter HQP1351 therapy cohort and best available therapy (BAT) cohort. When the subjects in the two cohorts reach EFS assessment, they can crossover to contralateral cohort if the investigator and Sponsor think they could be clinically benefited. During treatment, each subject will be assessed regularly for hematological, cytogenetic and molecular responses. At the same time, safety information also will be evaluated.

It is defined as the best response obtained by the subjects during the whole treatment process of the study.

It is defined as the best response obtained by the subjects during the whole treatment process of the study.
Overall survive (OS) By the end of Cycle 24 (each cycle is 28 days) OS is defined as the interval between the first dose date and date of death, censored at the last contact date to be alive.
Complete cytogenetic response (CCyR) By the end of Cycle 24 (each cycle is 28 days) CCyR is the proportion of patients achieving CCyR after being treated. It is defined as the best response obtained by the subjects during the whole treatment process of the study.
