Clinical Trial Summary

The goal of this study is to evaluate the efficacy and safety of a combination regimen of mitoxantrone hydrochloride liposome injection, cytarabine and venetoclax (MAV) in the treatment of relapsed or refractory (R/R) AML. It will also tentatively explore the correlation between different biological characteristics and therapeutic efficacy. The main questions it aims to answer are:Dose the combination regimen of MAV enhanced the composite complete remission in R/R AML? Participants will receive laboratory tests of bone marrow and blood specimens at regular times after MAV treatment.


Description:

Acute myeloid leukemia (AML) is a highly aggressive hematologic malignancy with a poor prognosis. The "3+7" regimen, combining anthracyclines with cytarabine, remains the standard treatment for first line treatment. However, about 20% of patients will develop into primary refractory disease, and more than 50% of patients who achieved complete remission will eventually relapse. For patients with R/R AML, there is currently no established standard treatment. Combining the third drugs with "3+7" regimen is one of the clinical exploration directions. The purpose of this prospective, single-center, single-arm, pahse II study is to evaluate the efficacy and safety of a combination regimen of mitoxantrone hydrochloride liposome injection, cytarabine and venetoclax in the treatment of R/R AML. All participants will receive MAV treatment including 24 mg/m2 mitoxantrone hydrochloride liposome on day 1, 1.0 g/m2 q12h cytarabine on day 1,3,5 and 400 mg venetoclax on day 2-10 with a dose escalation on day 2-4. Each cycle consists of 4 weeks. A maximum of 2 cycles of therapy are planned.
