Brief Summary

Acute myeloid leukemia (AML) represents the most prevalent leukemia type in China. Elderly patients (≥60 years old) have a high incidence rate, accounting for over half of all AML patients, with a median age of onset approximately 68 years. Elderly AML patients have a poor prognosis and are often accompanied with multiple high-risk factors.The 5-year overall survival (OS) is only 3-8%. Before the advent of new targeted drugs, for elderly patients with newly diagnosed AML who were suitable for intensive chemotherapy, the most commonly used chemotherapy regimen remained the classic "3 + 7" regimen. However, the complete remission (CR) rate after induction was approximately 40-60%. The majority of elderly patients were not eligible for allogeneic hematopoietic stem cell transplantation, resulting in a relatively poor long-term survival for elderly AML patients . With the emergence of new targeted drugs, clinical studies both domestically and internationally have demonstrated that the combination of various targeted drugs and demethylating agents has achieved favorable efficacy in elderly/unsuitable for intensive chemotherapy patients with newly diagnosed AML, prolonging their survival. Previously, we initiated a multicenter, prospective, randomized controlled clinical study (registration number: NCT06066242). The aim was to explore the optimal induction regimen for elderly fit patients with newly diagnosed AML. Preliminary data revealed that the regimen of daunorubicin (DNR) or idarubicin (IDA) combined with cytarabine (Ara - C, DA/IA) + venetoclax (Ven, DAV/IAV) had a higher induction remission rate (77.3% )than the DA/IA "3 + 7" and Ven + azacitidine (AZA) regimens (45% - 59%). However, compared to the induction remission rate of young adult patients with newly diagnosed AML (\> 85%), further improvement is still required. Previous research data show that HHT enhances the inhibitory effect of Ara-c on DNA synthesis in tumor cells by influencing cell cycle regulation. The combination of HHT and Ven can jointly affect the apoptotic pathway and enhance cell apoptosis. Therefore, this study intends to establish a prospective, randomized controlled clinical trial to compare the induction remission rates of the HHT + Ara-c + Ven (HAV) regimen with the DAV/IAV regimen, which,based on previous data, had the highest induction remission rate .

Outcome Measures

Primary Outcomes (1)

Secondary Outcomes (7)

• Complete remission (CR) rate or complete remission with partial hematologic recovery (CRh) rate or complete remission with incomplete hematologic recovery (CRi) rate

  Up to approximately eight weeks afer induction therapy

• Undectable Minimal residual disease (MRD) by flow cytometry compelete remission rates after induction

  Up to approximately eight weeks afer induction therapy

• Undectable Minimal residual disease (MRD) by flow cytometry complete remission rates in the whole treatment

  up to 1 years after the date of the last enrolled participants

• Relapse-free Survival (RFS)

  Up to approximately 1 years after the date of the last enrolled participants

Study Arms (2)

DAV/IAV

ACTIVE COMPARATOR

Induction therapy: Ara-C 100mg/m2/d, d1-5 Daunorubicin 60mg/m2/d, d1-2 or Idarubicin 10mg/m2/d, d1-2 Venetoclax 100mg d3, 200mg d4,400mg d5-11 If the treatment achieves CR/CRi/CRh, proceed directly to consolidation therapy. If the treatment does not achieve CR/CRi/CRh, enter the second induction phase with a different treatment regimen. Second Induction Phase: For patients with FLT3 or IDH1 mutations, targeted therapy can be chosen. If there is no FLT3 or IDH1 mutation or the patient is unwilling to use FLT3 or IDH1 inhibitors, switch to the HAV induction regimen. Consolidation therapy: 1\. intermediate-dose Ara-C (ID-Ara-C): 2 cycles are used. Ara-C 1 g/m2/q12h on days 1, 3, and 5 (for patients aged 60-70 years) or Ara-C 500 mg/m2/q12h on days 1, 3, and 5 (for patients aged 70 years or older) Maintenance therapy: VA regimen: 6 courses Azacitidine 75 mg/m2/d on days 1-5, Venetoclax 400 mg on days 1-7.

HAV

EXPERIMENTAL

Induction Therapy: Ara-C 100mg/m2/d, d1-5 HHT 2mg/m2/d, d1-5 Venetoclax 100mg d3, 200mg d4,400mg d5-11 If CR/CRi/CRh is achieved, proceed directly to consolidation therapy. If the treatment does not reach CR/CRi/CRh, enter the second induction phase with a different treatment regimen. Second course: For patients with FLT3 or IDH1 mutations, the corresponding targeted therapy can be selected, as before. For patients without FLT3 or IDH1 mutations or those who do not want to use FLT3 or IDH1 inhibitors, the DAV/IAV induction regimen is changed. If the treatment does not reach CR/CRi/CRh after two courses, the patient is discharged. Consolidation therapy: 1\. intermediate-dose Ara-C (ID-Ara-C): 2 cycles are used. Ara-C 1 g/m2/q12h on days 1, 3, and 5 (for patients aged 60-70 years) or Ara-C 500 mg/m2/q12h on days 1, 3, and 5 (for patients aged 70 years or older) Maintenance therapy: VA : 6 courses
