Trial Summary

What is the purpose of this trial?

This phase II trial studies how well venetoclax and azacitidine work for the treatment of acute myeloid leukemia after stem cell transplantation. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Chemotherapy drugs, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax and azacitidine after a stem cell transplant may help control high risk leukemia and prevent it from coming back after the transplant.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, it mentions that participants should not have uncontrolled infections or be on certain immune suppressive drugs, so it's best to discuss your specific medications with the trial team.

Is the combination of Venetoclax and Azacitidine safe for treating acute myeloid leukemia?

The combination of Venetoclax and Azacitidine has been studied for safety in patients with acute myeloid leukemia, showing common blood-related side effects. These studies indicate that while the treatment can be effective, it often comes with hematologic toxicities (blood-related side effects), which are important to monitor. ^{1 2 3 4 5}

What makes the drug combination of Venetoclax and Azacitidine unique for treating acute myeloid leukemia?

The combination of Venetoclax and Azacitidine is unique because it is specifically used for older patients or those who cannot undergo intensive chemotherapy, and it has been shown to improve survival rates compared to Azacitidine alone. ^{2 3 4 6 7}

Treatment Details

Interventions

• Azacitidine
• Venetoclax

Trial Overview The effectiveness of venetoclax combined with azacitidine is being tested as a treatment to prevent the return of acute myeloid leukemia after stem cell transplantation. Venetoclax targets proteins that cancer cells need to survive, while azacitidine interferes with their growth.

Participant Groups

Group I: Treatment (azacitidine, venetoclax) Experimental Treatment 2 Interventions

Patients receiving venetoclax and azacitidine for maintenance after allogeneic stem cell transplantation, receive azacitidine SC on days 1-5 and venetoclax PO QD on days 1-7. Patients receiving venetoclax and azacitidine for minimal residual disease after allogeneic stem cell transplant, receive azacitidine SC on days 1-5 and venetoclax PO QD on days 1-14. Treatment repeats every 4-8 weeks for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

Azacitidine is already approved in European Union, United States, Canada, Japan for the following indications:

Findings from Research

In a study of 57 elderly patients (average age 69.9 years) with acute myeloid leukemia, the combination of venetoclax and azacitidine (VEN + AZA) showed a high overall response rate of 87.5% and a complete remission (CR) rate of 68.8%, indicating strong efficacy in this population.

The treatment was associated with a median overall survival (OS) of 11.5 months, and achieving minimal residual disease (MRD) negativity (<0.1%) was more common with VEN + AZA compared to traditional chemotherapy, although older patients (≥75 years) and those with higher ECOG scores faced more challenges in achieving MRD negativity.

In a Japanese subgroup of the phase 3 VIALE-A trial, venetoclax-azacitidine significantly improved overall survival rates compared to placebo-azacitidine, with 67% of patients alive at 12 months versus 46% in the placebo group.

The treatment also resulted in a high complete response (CR) and CR with incomplete hematologic recovery (CRi) rate of 67%, while maintaining a safety profile similar to the global study, indicating it is a viable first-line treatment for Japanese patients with acute myeloid leukemia ineligible for intensive chemotherapy.

In a study of 13 patients with acute leukemia treated with venetoclax and azacitidine, 46% developed COVID-19, highlighting a significant risk associated with this treatment during the pandemic.

The study found that 33% of those who contracted COVID-19 died from the virus, indicating that COVID-19 can lead to severe outcomes in patients receiving AZA-VEN therapy.

In a phase 1/2 study involving six Japanese patients aged 60 and older with acute myeloid leukaemia, the combination of venetoclax and azacitidine demonstrated a high response rate, with 83% of patients achieving a response, including three complete remissions.

The treatment was generally well tolerated, with a median overall survival of 15.7 months, although some patients experienced serious adverse events, including grade 3 fungal pneumonia, which required treatment adjustments.

In a study of 50 adults with acute myeloid leukemia (AML) in Mexico and Peru, venetoclax-based therapy showed a high complete response rate of 78.6% in newly diagnosed patients and 45.5% in those with relapsed/refractory disease, indicating its efficacy in treating AML.

The median overall survival was 9.6 months for newly diagnosed patients and 8 months for relapsed/refractory patients, suggesting that venetoclax is a viable treatment option even in real-world settings, despite common hematologic toxicities and dose adjustments.

In a phase II study involving 60 older or unfit patients with newly diagnosed acute myeloid leukemia (AML), the combination of venetoclax with cladribine and low-dose cytarabine alternating with venetoclax and 5-azacitidine resulted in a high composite complete response rate of 93%.

The treatment showed promising overall survival and disease-free survival rates, with only one death occurring within 4 weeks, indicating that this regimen is effective and has a favorable safety profile for this patient population.

In patients with newly diagnosed unfit acute myeloid leukemia (AML), the combination of azacitidine and venetoclax is a standard first-line treatment.

However, patients with TP53-mutated AML and poor-risk cytogenetics do not benefit from adding venetoclax to azacitidine, suggesting that alternative treatment regimens should be considered for these individuals.
