safety and efficacy of venetoclax combination with decitabine(dec3-ven) in the treatment of aml in the adult

Conditions: Acute Myeloid Leukemia, Adult

Summary: this study proposes to conduct a prospective, multicenter, single-arm study to explore the efficacy and safety of venetoclax in combination with high-dose decitabine (dec3-ven) in new diagnosed adult patients with aml, and to provide evidence for the optimal selection of clinical treatment regimens, which is planned to be conducted in 10 research centers across the country.
