Brief Summary

To study the optimal therapeutic strategies for salvage treatment of refractory/relapsed AML, and to clarify the effectiveness and safety of various salvage treatment options. A prospective, multicenter, platform-type study was conducted to explore the overall response rate, tolerability, and survival of patients with R/R AML with different treatment regimens.

Conditions

AML; Refractory; Relapsed

Keywords

AML; Refractory; Relapsed

Outcome Measures

Arm 3

EXPERIMENTAL

For R/R AML patients without IDH1 or FLT3 mutations who have not been exposed to Venecra in the last 3 months, the investigators will determine whether they are fit patients based on physical status and comorbidivities, and if they are, they can be randomly assigned to Arm3 or Arm4 DAV/IAV/MAV Cytarabine 100mg/m2/d, d1-5 Daunorubicin 60mg/m2/d, d1-2, or Idarubicin 12mg/m2/d, d1-2, or mitoxantrone 8mg/m2/d d1-2 Venetoclax 100mg d3, 200mg d4, 400mg d5-11;

Drug: Ivosidenib,Venetoclax,gilteritinib,Selinexor

Arm 4

EXPERIMENTAL

HAV : Cytarabine 100mg/m2/d, d1-5 Homoharringtonine 2mg/m2 d1-5 Venetoclax 100mg d3, 200mg d4, 400mg d5-11

Drug: Ivosidenib,Venetoclax,gilteritinib,Selinexor

Arm 5

EXPERIMENTAL

A patient with R/R AML without IDH1 or FLT3 mutation who has not been exposed to Venetoclax in the last 3 months but who is judged by the investigators to be unfit based on physical fitness and comorbidivities is unfit to enter Arm5. Arm5: (up to 4 cycles available) VA : Azacytidine 75mg/m2/d d1-7 Venetoclax 100mg d1, 200mg d2, 400mg d3-21 400mg d22-28 (if the proportion of 21st bone marrow blasts are greater than 5%)

Drug: Ivosidenib,Venetoclax,gilteritinib,Selinexor

Arm 6

EXPERIMENTAL

Patients with R/R AML without IDH1 or FLT3 mutations who have been exposed to Vinecra within the last 3 months may be enrolled in the exploratory protocol group based on a comprehensive assessment of local drug availability and patient status: Arm6: The Investigator's choice (IC) option involves a range of drugs such as clatabine, PI3K inhibitors, histone deacetylase inhibitors, celinisol, and novel liposomes.

Drug: Ivosidenib,Venetoclax,gilteritinib,Selinexor

Arm 7

EXPERIMENTAL

According to the patient's condition and physical condition, evaluate whether there is a suitable new drug clinical trial to be enrolled. If there is, enter the Arm 7 (new drug clinical trial).

Drug: Ivosidenib,Venetoclax,gilteritinib,Selinexor

Interventions

Ivosidenib,Venetoclax,gilteritinib,Selinexor DRUG

if the target gene mutations are positive, enter arm1 or arm2. other conditions, enter the chemotherapy arms (Arm3-6)

Arm 1; Arm 2; Arm 3; Arm 4; Arm 5; Arm 6; Arm 7

Eligibility Criteria
