About this study

Official title: A Prospective,Randomized,and Comparative Study on the Efficacy of Venetoclax Combined With CACAG Regimen and BAT Regimen in the Treatment of Relapsed/Refractory Acute Myeloid Leukemia

The purpose of this study is to compare the efficacy and safety of venetoclax combined with CACAG regimen with BAT regimen in the treatment of relapsed/refractory acute myeloid leukemia.

Read the detailed description

Despite advances in therapies for acute myeloid leukemia (AML) in the past decades, some patients still suffer from relapsed/refractory (R/R) disease, resulting in poor outcomes. With a median overall survival (OS) of 4-7 months under classic chemotherapy approaches, it is imperative to explore new treatment options.Accumulating research has demonstrated the importance of epigenetic modification in the pathogenesis of chemoresistance. Recent studies have shown that combining venetoclax with hypomethylating agents (HMAs) such as azacitidine, or low-dose cytarabine (LDAC) improves the response and survival rates in R/R AML patients. To enhance the response rate, we designed a regimen that combines chidamide, azacitidine, cytarabine, aclarubicin, and G-CSF with venetoclax (CACAG+VEN regimen) for the treatment of patients with R/R AML. In this study, we intend to compare the efficacy and safety of venetoclax combined with the CACAG regimen with Best-Available Therapy(BAT) regimen in the treatment of relapsed/refractory acute myeloid leukemia.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 2 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Daihong Liu, doctor (+8613681171597, daihongrm@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate (ORR) after 1 course of treatment (time frame: 1 months after the start of study treatment). It is what the study was designed to measure, not a finding.
