About this study
Official title: A Multicenter, Single-arm Clinical Study of Venetoclax Combined With Azacitidine Induction and Bridging to Allogeneic Hematopoietic Stem Cell Transplantation for the Treatment of Hypoplastic or Secondary Acute Myeloid Leukemia
The purpose of this study is to explore the efficacy and safety of venetoclax combined with azacitidine（VA) induction followed by bridging allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of hypoplastic and secondary acute myeloid leukemia (AML).
Read the detailed description
Under the traditional intensive chemotherapy model, patients with hypoplastic or secondary acute myeloid leukemia (AML) often have poor bone marrow reserve and prolonged post-chemotherapy cytopenia, leading to high early mortality, low remission rates, and short median survival. To address this, the use of venetoclax combined with a hypomethylating agent (the VA regimen) as induction therapy significantly improves complete remission (CR) and overall survival (OS). Subsequent bridging to allogeneic hematopoietic stem cell transplantation (allo-HSCT) as consolidation further enhances OS and relapse-free survival (RFS). This combined strategy demonstrates a clear synergistic effect: the VA regimen effectively increases the transplantation rate, and for patients with relapsed/refractory (R/R) AML, a low-intensity regimen followed by bridging transplantation is non-inferior to traditional intensive chemotherapy, achieving a "1+1>2" therapeutic benefit. Therefore, the investigators conducted a prospective study to evaluate the efficacy and safety of VA regimen induction followed by allo-HSCT in patients with hypoplastic and secondary AML.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Venetoclax (VEN)Drug
Venetoclax was administered at 100 mg on day 1, 200 mg on day 2, and 400 mg on days 3-28 of cycle 1.
Azacitidine (AZA)Drug
Azacitidine was administered at 75 mg/m² on days 1-7 of cycle 1.
