• Conditions: Relapsed/Refractory Acute Myeloid Leukaemia; Myeloid Malignancy
• Interventions: Drug: mitoxantrone hydrochloride liposome; Drug: Cytarabine; Drug: Venetoclax

• Registration Number: NCT06621212
• Lead Sponsor: First Affiliated Hospital of Zhejiang University

Brief Summary

The purpose of this prospective, single-center, single-arm, exploratory study is to evaluate the efficacy and safety of a combination regimen of mitoxantrone hydrochloride liposome injection, standard-dose of cytarabine and venetoclax (MAV) in the treatment of relapsed or refractory (R/R) AML. The study plan to enroll 20 R/R AML patients who are expected to ...

Detailed Description

For patients with R/R AML, there is currently no established standard treatment. Previous research suggests that mitoxantrone could against venetoclax-resistant leukemia stem cells (LSCs) by modulating mitochondrial calcium levels. Based on the potentially synergistic killing effect of mitoxantrone and venetoclax, a phase 2 study is underway in R/R AML. Pati...

Primary Outcome Measures

Name	Time	Method
Composite complete remission (CRc) rate	At the end of each cycle (each cycle is 28 days), up to 2 cycles	Complete remission plus complete remission with incomplete hematologic recovery (CR+CRi). Response is assessed according to the the European LeukemiaNet (ELN) 2022 criteria.

Secondary Outcome Measures

Name	Time	Method
Overall response rate (ORR)	At the end of each cycle (each cycle is 28 days), up to 2 cycles	CR+CRi+morphologic leukemia-free state+partial remission (CR+CRi+MLFS+PR). Response is assessed according to the the European LeukemiaNet (ELN) 2022 criteria.
Relapsed free survival (RFS)	up to 12 months	Defined only for patients achieving CR or CRi. Measured from the date of achievement of remission until the date of hematologic relapse or death from any cause.
Event free survival (EFS)	up to 12 months	Defined for all patients in the study. Measured from day 1 of treatment to the date of treatment failure, hematologic relapse from CR/CRi or death from any cause, whichever occurs first.
overall survival (OS)	up to 12 months	Defined for all patients in the study. Measured from day 1 of treatment to the date of death from any cause.
Rate of CR/CRi without minimal residual disease	At the end of each cycle (each cycle is 28 days), up to 2 cycles	Percentage of participants who achieve a CR MRD-/CRi MRD- as defined by investigators based on ELN 2022 criteria. MRD level is detected by flow cytometry and negtive MRD is defined as MRD value \<0.1%.
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]	From day 1 of treatment to 28 days after the last dose	The safety of the drug was evaluated by NCI-CTC AE 5.0 standard which including hematologic and non-hematologic toxicity.
