Maintenance Therapy of Hypomethylating Agent (HMA) in Favorable Risk Acute Myeloid Leukemia (AML) Patients

Maintenance Therapy of Hypomethylating Agent (HMA) in Favorable Risk Acute Myeloid Leukemia (AML) Patients: A Single Arm, Multi Center Clinical Trial

HMA maintenance therapy is expected to benefit overall survival (OS) and relapse free survival (RFS) in AML patients with favorable risk.

Study Overview

• Status: Recruiting
• Conditions: Acute Myeloid Leukemia
• Intervention / Treatment: Drug: Hypomethylating agent, Azacitidine or Decitabine

Detailed Description

Applying hypomethylating agents, azacitidine or decitabine as maintenance therapy in favorable-risk AML may prolong the remission duration and further improve their long-term survival.

8. Have the ability to understand and be willing to sign the informed consent form for this trial.

Exclusion Criteria:

7. Patients with mental disorders or other conditions whereby informed consent cannot be obtained and where the requirements of the study treatment and procedures cannot be met.
8. Liver function abnormalities (total bilirubin > 1.5 times the upper limit of the normal range, Alanine Aminotransferase (ALT) / Aspartate Aminotransferase (AST) > 2.5 times the upper limit of the normal range or patients with liver involvement whose ALT/AST > 1.5 times the upper limit of the normal range), or renal anomalies (serum creatinine > 1.5 times the upper limit of the normal value).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Relapse free survival (RFS)	It is measured from the date of entry into this trial to the date of hematologic relapse or death from any cause; subjects not known to have any of these events are censored on the date they were last examined.	5 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall survival (OS)	It is measured from the date of entry into this trial to the date of death from any cause; subjects not known to have died at last follow-up are censored on the date they were last known to be alive.	5 year
Cumulative incidence of relapse (CIR)	CIR defined as from the time of recruitment to the study until the date of hematologic relapse.	5 year
