Selinexor、Venetoclax and Azactidine in the Treatment of ND AML Patients Who Are Not Eligible for Intense Chemotherapy

Overview

This study is a single arm open exploratory clinical trial to evaluate the efficacy and safety of selinexor combined with venetoclax and azacitidine. This study will be divided into two stages: dose increasing stage and dose expanding stage. In the dose-increasing stage, the study induction therapy was designed using a 3+3 design. The induction therapy and consolidation therapy of the subjects will be administered at RP2D doses. During this study period, there were a total of 4 cycles. The treatment cycle of the subjects will include 2 cycles of induction therapy and up to 2 cycles of consolidation therapy. In addition, if the subject does not achieve remission (CR/Cr or PR) after 2 cycles of consolidation treatment (at the end of the 4th course), the study will be terminated by the subject, and the clinical doctor will choose the subsequent treatment for the subject based on clinical experience.

This study is a single arm open exploratory clinical trial to evaluate the efficacy and safety of selinexor combined with venetoclax and azacitidine. This study will be divided into two stages: dose increasing stage and dose expanding stage. In the dose-increasing stage, the study induction therapy was designed using a 3+3 design. In this stage, three dosage groups were set up, namely selinexor 60mg QW, 40mg BIW, or 60mg BIW, in combination with venetoclax 100mg d1 200mg d2 400mg d3-28, orally once a day, and azacitidine 75mg/m2, d1-7, subcutaneously. The regimen was repeated every 28 days. In this case, RP2D is determined based on MTD, safety, and all other data. The methods of venetoclax and azacitidine remain unchanged during consolidation therapy. Before RP2D is determined, the dosage of selinexor is determined by the researchers based on individual subject tolerance. After RP2D is determined, the study enters the second stage of dose expansion. The induction therapy and consolidation therapy of the subjects will be administered at RP2D doses. During this study period, there were a total of 4 cycles. The treatment cycle of the subjects will include 2 cycles of induction therapy and up to 2 cycles of consolidation therapy. In addition, if the subject does not achieve remission (CR/Cr or PR) after 2 cycles of consolidation treatment (at the end of the 4th course), the study will be terminated by the subject, and the clinical doctor will choose the subsequent treatment for the subject based on clinical experience. The subjects will participate in the screening period, treatment period, and follow-up period. The screening period lasts for a maximum of 28 days before medication. The treatment period lasts from the first day of the first cycle to the end of the study treatment. The follow-up period starts after the end of treatment and lasts for at least 12 months.
