Clinical Trial Summary

In recent years, the efficacy of AML has been greatly improved, which is mainly due to the following aspects: the development of individualized treatment strategies based on genetic prognosis stratification, the application of high-dose cytarabine-containing induction and consolidation regimens , the choice of allogeneic or autologous hematopoietic stem cell transplantation, etc. However, 20%-30% of young patients and 40%-50% of elderly patients will relapse again, and 20%-40% of patients cannot be relieved after standard induction regimens, that is, relapsed and refractory AML. The re-induction remission rate is low, the survival period is short, and the prognosis is extremely poor. There is still a lack of standard treatment options. Although a small number of patients can benefit from allogeneic hematopoietic stem cell transplantation (allo-HSCT), most patients lack suitable donors. The choice of high-dose chemotherapy is a salvage treatment option, but treatment-related hematological or non-hematological toxicities and high lethality make the option controversial, especially for the elderly. The development of new low-toxic targeted drugs is a future trend, and the design of new efficient and safe chemotherapy regimens is also a way of thinking. This study designed a prospective single-center clinical randomized controlled study plan, that is, the use of bortezomib (1.3mg/m2, d1, 4, 8, 11) combined with DAG regimen in the treatment of refractory/relapsed AML, to evaluate the clinical efficacy (complete remission rate , total effective rate, 2-year progression-free survival rate and 2-year overall survival rate), and observe how safe the new program is. The results of the research will make it possible to design a high-efficiency, low-toxicity and high-feasibility chemotherapy regimen for refractory/relapsed patients, and guide the clinical treatment of relapsed/refractory acute leukemia.

Clinical Trial Description

This study aimed to evaluate the clinical efficacy of bortezomib combined with DAG regimen in the treatment of refractory and relapsed AML (complete remission rate, overall effective rate, 2-year progression-free survival rate and 2-year overall survival rate), and to compare the effects of the two regimens. Safety, guiding the clinical treatment of relapsed/refractory acute leukemia. For the smooth development of this study, the relevant monitoring indicators of the study are as follows: 1. Select suitable subjects with relapsed/refractory acute myeloid leukemia according to the inclusion criteria, and explain the treatment indications of bortezomib and the purpose of this clinical study to the subjects and their families. 2. The attending doctor communicates with the subject and his family members according to the condition of the subject and signs the informed consent. The subject needs to perform the following tests: three routine tests, cerebrospinal fluid routine and biochemistry, liver function, kidney function, PNH test, anemia four Items (ferritin, folic acid, vitamin B12, erythropoietin), blood sugar, blood lipids, electrolytes, myocardial enzymes, coagulation function, HIV antibody, syphilis, screening of related hepatitis virus markers, tumor markers, chest X-ray, Electrocardiogram, CT or MRI examination, etc.; if conditions permit, immune function and T cell subsets can be monitored. 3. Clinical research: According to the research design, this clinical research was carried out, and relevant indicators such as the incidence of third-degree and fourth-degree myelosuppression and infection after chemotherapy, the rate of antibiotic use, the delay rate of chemotherapy, and the extension time of chemotherapy were recorded. The incidence and severity of adverse drug reactions were recorded. ;
