What You Need to Know Before You Apply

What is the purpose of this trial?

This study aims to treat non-elderly adult patients, who were previously untreated for acute myeloid leukemia, using venetoclax and azacitidine.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot take certain steroids or drugs that affect liver enzymes (CYP3A inhibitors or inducers) within 7 days before starting the study. It's best to discuss your current medications with the trial team.

How is 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. This combination targets leukemia cells more effectively by using Venetoclax to block a protein that helps cancer cells survive, while Azacitidine interferes with the growth of cancer cells. ^{1 2 3 4 5}

What data supports the effectiveness of the drug combination Venetoclax and Azacitidine for treating leukemia?

Research shows that the combination of Venetoclax and Azacitidine improves remission rates and survival in older or unfit patients with acute myeloid leukemia compared to Azacitidine alone. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

Adults aged 18-59 with newly diagnosed acute myeloid leukemia (AML) who haven't been treated before can join. They should be in relatively good health, with an ECOG score of ≤2, and have normal liver and kidney function. Men must use contraception; women not post-menopausal or without a hysterectomy/oophorectomy must use two forms of birth control or abstain from sex.

Inclusion Criteria

I can take care of myself and am up and about more than half of my waking hours.

I will use birth control from the start of the study drug until 90 days after the last dose.

I am a pre-menopausal woman who agrees to use two forms of birth control or abstain from sex.

Exclusion Criteria

I have been treated for MDS or AML, but ATRA for suspected APL doesn't disqualify me.

I cannot take medicine by mouth due to a digestive condition.

I am currently being treated for a serious infection that is not under control.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive up to four cycles of venetoclax and azacitidine. Azacitidine is given intravenously for 7 days, and venetoclax is given orally, starting at 100mg and progressing to 600mg.

16 weeks

Follow-up

Participants are monitored for safety and effectiveness after treatment, including response rate and incidence of minimal residual disease.

4 years

Maintenance or Extension

Depending on recovery, participants may continue medication, receive maintenance therapy, or pursue an allogeneic stem cell transplant.

What Are the Treatments Tested in This Trial?

Interventions

• Azacitidine
• Venetoclax

Trial Overview The trial is testing the combination of two drugs, Venetoclax and Azacitidine, as a treatment for AML in non-elderly adults. It's aimed at those who are newly diagnosed and have not received any prior treatments for their condition.

How Is the Trial Designed?

Group I: Azacitidine and Venetoclax Experimental Treatment 2 Interventions

Azacitidine will be given intravenously for 7 days. Venetoclax will be given orally. The patient will start out with 100mg and progress to 600mg. Once 600mg is reached, the patient will stay at this dose until the 28 day cycle is finished.

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

Published Research Related to This Trial

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 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 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 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 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.
