Summary

Leukemia is one of the common malignant tumors that threaten human health. Although the efficacy of AML treatment has improved significantly in recent years, it remains one of the major diseases threatening human health. Current research on AML treatment mainly has two directions. One is the addition of new targeted therapy drugs, and the other research direction is to enhance the intensity of AML chemotherapy, including the use of large doses of anthracycline drugs or the use of high-dose cytarabine treatment. Since the 1990s, induction remission has been achieved by using anthracyclines in combination with high-dose cytarabine. The ECOG (Eastern Cooperative Oncology Group) contends that high-dose induction chemotherapy fails to enhance the bone marrow remission rate but elevates the chemotherapy-related mortality rate. Bradstock and the Australian Group also noted that although it does not increase the bone marrow remission rate, it can result in longer survival time and disease-free survival time. The clinical study from EORTC-GIMEMA AML-12 discovered that AML patients under the age of 45 could benefit from induction therapy incorporating high-dose cytarabine. In our previous randomized controlled clinical trials, it was found that the HAD and DA regimens containing intermediate-dose cytarabine could enhance the complete remission rate and improve the overall survival of adult AML. However, the degree of benefit varies among different AML subgroups. The abnormalities of RUNX1-RUNX1T1 and CBFβ-MYH11 respectively involve a subunit of CBF (core binding factor), thus the two are collectively called CBF leukemia. Previous retrospective studies show that this type of leukemia benefits from intensified treatment regimens such as FLAG. However, at present, there is a lack of prospective randomized controlled clinical studies to confirm this. Therefore, in this study, we intend to further verify through a prospective randomized controlled clinical trial whether the induction treatment regimen containing intermediate-dose cytarabine can improve the long-term efficacy of adult RUNX1-RUNX1T1 acute myeloid leukemia.

Detailed description

This study is a prospective, randomized, controlled phase III clinical trial that plans to enroll adult patients with AML who meet the WHO (2022) or ICC criteria for eligibility for intensive chemotherapy with RUNX1-RUNX1 fusion. For patients who meet the inclusion criteria and do not meet any exclusion criteria, they will be randomly assigned to either the A group, which receives standard-dose DA induction therapy, or the B group, which receives intermediate-dose DA induction therapy. Patients who do not achieve complete remission after one cycle of induction therapy will receive IAC reinduction therapy. Patients who achieve complete remission after one or two cycles of induction therapy will proceed to receive three cycles of high-dose cytarabine consolidation therapy. Patients who do not achieve complete remission after two cycles of induction therapy will be withdrawn from the treatment protocol. For patients whose fusion gene levels do not meet the criteria, allogeneic hematopoietic stem cell transplantation is recommended.
