About

This study evaluates the efficacy and safety of the combination of idarubicin and cytarabine induction followed by intermediate-dose cytarabine consolidation with venetoclax in the treatment of newly diagnosed adult acute myeloid leukemia (AML). This study includes the induction and consolidation phases of AML treatment.

Full description

This is a prospective, multicenter, open-label, single-arm clinical study aimed at observing and evaluating the effectiveness and safety of idarubicin and cytarabine induction followed by intermediate-dose cytarabine consolidation therapy in newly diagnosed adult AML. The results of this study will help to understand the efficacy and safety of idarubicin and cytarabine combination therapy followed by intermediate-dose cytarabine consolidation in newly diagnosed adult AML, providing guidance for clinical practice. Acute myeloid leukemia (AML) is a heterogeneous hematopoietic stem/progenitor cell malignancy. The World Health Organization (WHO) defines AML as a myeloid tumor with primitive cells accounting for 20% or more in peripheral blood or bone marrow. It is also the most common acute leukemia in adults and the tenth leading cause of cancer-related deaths worldwide.Treatment for AML consists of induction therapy and consolidation therapy (including chemotherapy and hematopoietic stem cell transplantation (HSCT)). The most commonly used is the 3+7 regimen. In 2018, our center conducted a retrospective analysis of 242 newly diagnosed AML patients treated with the standard IA regimen, evaluating its efficacy and adverse reactions, and conducting prognostic factor analysis. The study results showed that the CR rate of one course of IA regimen induction therapy was 81.28%; after repeated induction therapy, the CR rate reached 92.34%, confirming that the IA regimen induction therapy has a high CR rate, consistent with many literature reports. The FDA has approved the combination therapy of Venetoclax and Decitabine/Azacitidine for elderly (>60 years old) newly diagnosed AML patients who are not eligible for intensive chemotherapy. Venetoclax, the first highly selective BCL-2 inhibitor available globally, is a BH3 mimetic that selectively binds to the BCL-2 protein, displacing and releasing pro-apoptotic proteins that were originally bound to BCL-2, effectively inducing apoptosis in tumor cells. Currently, preclinical studies have confirmed that the combination of idarubicin and cytarabine with venetoclax has a synergistic effect in the anti-tumor treatment of AML. Based on this, the CAVEAT study included 51 newly diagnosed primary or secondary AML patients aged ≥65 years who had not previously received intensive therapy (including AML patients with monosomal karyotype aged ≥60 years). The median age of the patients was 72 years. The treatment regimen for induction and consolidation therapy included idarubicin, cytarabine, and venetoclax (with reduced intensity for idarubicin and cytarabine). The overall response rate (ORR) was 72%, and the median overall survival (OS) was 11.2 months. Compared to secondary AML, patients with primary AML had a longer median OS (31.3 months vs 6.1 months). The most common non-hematologic adverse reactions included febrile neutropenia (55%), sepsis (35%), and diarrhea (35%). These studies suggest that the combination of idarubicin, cytarabine, and venetoclax is safe and tolerable in elderly fit AML patients, and can provide higher remission rates and longer survival. The results of this study also partly confirm the safety of venetoclax in combination with cytarabine and idarubicin for induction chemotherapy in elderly AML patients. Given the favorable response rates and survival benefits achieved with the combination of VEN and IA in elderly patients with primary AML, we plan to design a prospective, single-arm, multicenter exploratory clinical trial to determine the efficacy and safety of the IA-based induction regimen combined with VEN (IAV regimen) followed by consolidation therapy with intermediate-dose cytarabine and venetoclax in newly diagnosed adult AML patients. This trial aims to provide evidence-based support for novel induction and consolidation treatment strategies for this patient population. In this study, we also plan to evaluate the efficacy and safety of the combination of idarubicin, cytarabine, and venetoclax as induction therapy followed by consolidation therapy with intermediate-dose cytarabine and venetoclax in newly diagnosed adult AML patients. The aim is to provide a safer and more effective treatment option for these patients. After signing the informed consent form, young newly diagnosed/eligible AML patients for intensive therapy will undergo various examinations as specified during the screening period. All eligible participants who do not meet the exclusion criteria should be followed up at baseline and on days 1, 3, 5, 7, 9, 11, 13, 15, and 21 during the induction treatment phase, and on days 1 and 21 of each cycle during the consolidation treatment phase. Follow-up visits should also be conducted at the time of withdrawal from the study or at the end of the study for assessment and monitoring. After signing the informed consent form, young newly diagnosed/fit for intensive therapy AML patients will undergo screening and various tests as specified during the screening period. All eligible participants who do not meet the exclusion criteria will be assessed at baseline and at days 1, 3, 5, 7, 9, 11, 13, 15, and 21 during the induction therapy phase, and on the first and twenty-first day of each cycle during the consolidation therapy phase. Follow-up visits will be conducted at the time of withdrawal/study completion. Specific treatment plan: Induction therapy: Venetoclax: 100mg on day 1, 200mg on day 2, 400mg on days 3-8; oral administration.Idarubicin: 10-12mg/m2 on days 1-3; intravenous infusion.Cytarabine: 100mg/m2 on days 1-7; intravenous infusion or subcutaneous injection. Consolidation therapy after remission: Venetoclax: 400mg on days 1-7; oral administration.Cytarabine: 2g/m2 every 12 hours on days 1-3; intravenous infusion.Four cycles in total.Patients who meet the criteria for autologous stem cell transplantation (ASCT) during the treatment process can undergo ASCT.Patients who meet the transplantation criteria and have a suitable donor can undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT).
