Mitoxantrone Hydrochloride Liposome in Combination With Cytarabine and Venetoclax Regimen in Newly Diagnosed Elderly AML

Phase 2

Recruiting

• Conditions: Acute Myeloid Leukemia
• Interventions: Drug: Mitoxantrone hydrochloride liposome; Drug: Cytarabine; Drug: Venetoclax

• Registration Number: NCT06621199
• Lead Sponsor: First Affiliated Hospital of Zhejiang University

Brief Summary

This is a phase 2 study to evaluate the efficacy and safety of mitoxantrone hydrochloride liposome in combination with cytarabine and venetoclax (MAV) regimen in newly diagnosed elderly AML. To account, conservatively, for a 10% dropout rate before study completion, we planned to include 42 patients. The primary endpoint is 2-year event free survival(EFS).

Detailed Description

The optimal induction chemotherapy regimen for newly diagnosed elderly AML patients who are eligible for intense chemotherapy is currently not well defined. Mitoxantrone hydrochloride liposome (Lipo-MIT) is an innovative anthracycline nano-drug, which has been demonstrated favorable pharmacokinetic characteristics, high cardiac safety, and shown preliminary ...

Primary Outcome Measures

Name	Time	Method
2-year event-free survival (EFS) rate	up to 2 years	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.

Secondary Outcome Measures

Name	Time	Method
Composite complete remission (CRc) rate of induction therapy	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.
Overall response rate (ORR) of induction therapy	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 2 years	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.
Overall survival (OS)	up to 2 years	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 measurable residual disease after induction therapy	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 regimen was evaluated by NCI-CTC AE 5.0 standard which including hematologic and non-hematologic toxicity.
