A Clinical Study of VA-CAG as Induction Therapy in Newly Diagnosed AML Patients

Not Applicable

Completed

• Conditions: Acute Myeloid Leukemia
• Interventions: Drug: Venetoclax in combination with azacitidine and CAG

• Registration Number: NCT05662956
• Lead Sponsor: Hematology department of the 920th hospital

Brief Summary

This study aims to assess the therapeutic efficacy and safety of venetoclax in combination with azacitidine and CAG(VA-CAG) as induction regimen in newly diagnosed young patients with acute myeloid leukemia(AML).

Detailed Description

This is an open-label, multicenter, phase II clinical trial to assess the therapeutic efficacy and safety of venetoclax in combination with azacitidine (VA) and CAG (G-CSF priming, low dose cytarabine, and aclarubicin) as induction regimen in newly diagnosed patients with acute myeloid leukemia (AML).

The combination of venetoclax and azacitidine is the standard therapy for elderly (\> 60 year old) patients with newly diagnosed AML who are not eligible for intensive chemotherapy. Previous studies have shown that venetoclax plus intense chemotherapy represent promising efficacy in de novo AML patients with high complete remission rates and good tolerance. The preliminary results suggest that venetoclax in combination with azacitidine and CAG are well tolerated and effective for newly diagnosed young patients with AML. Thus, this phase II clinical trial is going to further explore its efficacy and safety. It is expected that about 100 patients will take part in this trial.

Arm && Interventions

Group	Intervention	Description
Treatment group	Venetoclax in combination with azacitidine and CAG	Induction: Subjects who meet the enrollment conditions will receive Venetoclax plus Azacitidine and CAG(VA-CAG) . Participants will receive this induction Therapy as azacitidine on days 1-7, venetoclax aily on days 1-28, cytarabine q12h on days 1-7, aclacinomycin on days 1,3,5,7, and granulocyte colony-stimulating factor on days 0-8. Participants will receive second induction if not reach complete remission. Consolidation: If patients are intermediate or poor risk and have plans for allogeneic hematopoietic stem-cell transplantation(allo-HSCT) , high dose cytarabine (3g/m2 q12h days 1-3) for 1-2 cycles and follow up with allo-HSCT. In other cases, high dose cytarabine for 4 cycles.

Primary Outcome Measures

Name	Time	Method
CR rate	At the end of Cycle 1 of induction (each cycle is about 30 days)

Secondary Outcome Measures

Name	Time	Method
Adverse Events	From the first day of induction until the starting day of the next cycle of therapy (up to 60 days）	Safety and tolerability analysis will be assessed by the Common Toxicity Criteria for Adverse Events (CTCAE) version 5.0.
Duration of remission	From the date of the first remission until the date of relapse (assessed up to 30 months)	DOR was defined as the period from the time to acquire CR until relapse
Minimal Residual Disease negative remission rate (MRD-negative rate)	After 1 cycle of induction (each cycle is about 30 days)	Percentage of participants who converted to MRD \< 10\^-3 by flow cytometry before initiation of consolidation therapy.
