Combining Venetoclax, Chidamide, and Azacitidine for treating relapsed AML

A Multi-center, Prospective, Single-arm Study of Venetoclax Combining Chidamide and Azacitidine (VCA) in the Treatment of Refractory/Relapsed Acute Myelogenous Leukemia (R/R AML)

PHASE2 · The First Affiliated Hospital of Xiamen University · NCT05305859

This study is testing a new combination of three drugs to see if it can help people with relapsed acute myeloid leukemia feel better and achieve longer-lasting results.

What this trial studies

This clinical trial evaluates the safety and efficacy of a combination treatment involving Venetoclax, Chidamide, and Azacitidine for patients with relapsed or refractory acute myeloid leukemia (AML). The study builds on previous findings that show Venetoclax and Azacitidine can achieve a complete response rate of 30-40%, but with a limited duration of response. By adding Chidamide, a histone deacetylase inhibitor, researchers aim to enhance the treatment's effectiveness. The trial will monitor patient responses and tolerability to this new regimen.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with relapsed or refractory acute myeloid leukemia.

Not a fit: Patients with acute promyelocytic leukemia or significant cardiovascular issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with relapsed or refractory AML.

How similar studies have performed: Previous studies have shown promising results with similar combinations, but this specific regimen is novel.

* Mental disorders that hinder research participation
* Previous solid organ transplantation (SCT treatment is allowed in advance, but if the patient has GVHD or is still receiving immunosuppression/GVHD treatment, it is not allowed)
