What You Need to Know Before You Apply

What is the purpose of this trial?

Part 1b of this clinical research study is to find the highest tolerable dose of SNDX-5613 that can be given in combination with ASTX727 (a combination of the drugs decitabine/cedazuridine) and venetoclax for patients with acute myeloid leukemia (AML) or those with a mixed phenotype acute leukemia with a myeloid phenotype (MPAL).Part 2 of this study is to learn if the dose of study drugs found in Part 1b can help to control AML/MPAL

Will I have to stop taking my current medications?

The trial does not specify if you must stop all current medications, but it does not allow other chemotherapeutic or anti-leukemic agents during the study, except for certain cases like intrathecal chemotherapy or hydroxyurea. You should discuss your current medications with the study team to see if they are allowed.

Is the combination of SNDX-5613, ASTX727, and Venetoclax safe for humans?

The combination of Venetoclax with decitabine (ASTX727) has been studied in elderly patients with acute myeloid leukemia and was generally well tolerated, with common side effects including nausea, diarrhea, and fatigue. No serious safety concerns like tumor lysis syndrome were observed in these studies.12345

What makes the drug combination of SNDX-5613, ASTX727, and Venetoclax unique for treating acute myeloid leukemia?

This drug combination is unique because it includes SNDX-5613, a novel component not commonly used in standard treatments for acute myeloid leukemia, alongside ASTX727 and Venetoclax, which have shown promising results in older patients or those unfit for intensive chemotherapy. The combination aims to enhance treatment efficacy by targeting different mechanisms involved in leukemia cell survival.13678

What data supports the effectiveness of the drug combination SNDX-5613, ASTX727, and Venetoclax for treating acute myeloid leukemia?

Research shows that combining Venetoclax with Decitabine or Azacitidine is effective for older patients with acute myeloid leukemia, achieving high remission rates and longer survival compared to Decitabine alone.13469

Published Research Related to This Trial

In a study of 22 heavily pre-treated patients with relapsed or refractory acute myeloid leukaemia (RR-AML), the combination of venetoclax and decitabine resulted in a 45.5% overall response rate, with 40.9% achieving complete remission, demonstrating its efficacy in a real-world setting.
While the treatment was effective, it was associated with significant side effects, including grade IV neutropenia and thrombocytopenia in all patients, but no deaths were attributed to the treatment side effects, indicating that the adverse effects were manageable.
Efficacy of Venetoclax Combined with Decitabine-Based Treatment for Heavily Pre-Treated Relapsed or Refractory AML Patients in a Real-World Setting.Tong, J., Zhao, N., Hu, X., et al.[2022]
In a study involving 145 older patients (median age 74) with acute myeloid leukemia (AML) who were ineligible for intensive chemotherapy, the combination of venetoclax with decitabine or azacitidine resulted in a high complete remission (CR) rate of 67%, demonstrating its efficacy in this challenging population.
The treatment was well tolerated, with no cases of tumor lysis syndrome reported, and the median overall survival was 17.5 months, indicating that venetoclax combined with hypomethylating agents is a promising option for elderly patients with AML.
Venetoclax combined with decitabine or azacitidine in treatment-naive, elderly patients with acute myeloid leukemia.DiNardo, CD., Pratz, K., Pullarkat, V., et al.[2021]
In a study comparing older adults with newly diagnosed acute myeloid leukemia (AML), those treated with the combination of decitabine (DEC) and venetoclax (VEN) had a significantly longer median overall survival of 13.4 months compared to 8.3 months for those receiving DEC alone.
The combination therapy also resulted in a higher response rate of 70.3% versus 24.3% for DEC monotherapy, indicating that DEC+VEN is more effective in treating AML without increasing short-term mortality rates.
