Trial Summary

What is the purpose of this trial?

This phase II trial studies how well liposome-encapsulated daunorubicin-cytarabine and venetoclax work in treating participants with acute myeloid leukemia that has come back (relapsed), does not respond to treatment (refractory), or has not been treated (untreated). Drugs used in chemotherapy, such as liposome-encapsulated daunorubicin-cytarabine and venetoclax, 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.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, prior therapy with certain drugs like hydroxyurea, hematopoietic growth factors, or tretinoin is allowed without a break, and a specific dose of ara-C is allowed if given more than 48 hours before joining the trial.

What data supports the effectiveness of the drug Liposomal Daunorubicin-Cytarabine (CPX-351) for treating Acute Myeloid Leukemia?

Research shows that CPX-351 significantly improved survival rates in older adults with high-risk acute myeloid leukemia compared to traditional chemotherapy. It also had higher rates of complete remission and a similar safety profile, making it an important treatment option for this condition. ^{1 2 3 4 5}

Is the treatment Liposomal Daunorubicin-Cytarabine + Venetoclax safe for humans?

The treatment using Liposomal Daunorubicin-Cytarabine, also known as CPX-351 or Vyxeos, has been shown to have an acceptable safety profile in older adults with certain types of acute myeloid leukemia, with side effects similar to traditional chemotherapy. It is approved for use in several countries and has been studied in clinical trials, indicating it is generally safe for human use in the conditions tested. ^{1 2 3 4 6}

What makes the drug Liposomal Daunorubicin-Cytarabine + Venetoclax unique for treating acute myeloid leukemia?

This drug is unique because it uses a liposomal formulation to deliver a fixed, synergistic ratio of daunorubicin and cytarabine, which enhances its effectiveness and prolongs survival compared to traditional chemotherapy. The liposome helps protect the drugs from being broken down too quickly, allowing for better targeting of leukemia cells and potentially reducing side effects. ^{2 3 4 5 7}

Treatment Details

Interventions

• Liposome-encapsulated Daunorubicin-Cytarabine (Anti-tumor antibiotic, Anti-metabolites)
• Venetoclax (B-cell lymphoma-2 (BCL-2) inhibitor)

Trial Overview The trial is testing a combination of chemotherapy agents: liposome-encapsulated daunorubicin-cytarabine and venetoclax in patients with Acute Myeloid Leukemia. It aims to see how well these drugs work together in different scenarios such as relapsed/refractory AML or newly diagnosed patients.

Participant Groups

Group I: Treatment (CPX-351, venetoclax) Experimental Treatment 2 Interventions

INDUCTION: Participants receive liposome-encapsulated daunorubicin-cytarabine IV over 90 minutes on days 1, 3, and 5 of cycle 1 and on days 1 and 3 of cycle 2. Participants also receive venetoclax PO QD on days 2-21. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. CONSOLIDATION: Participants receive liposome-encapsulated daunorubicin-cytarabine IV over 90 minutes on days 1 and 3 and venetoclax PO QD on days 2-21. Treatment repeats every 28 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity.

Quality-adjusted Time Without Symptoms of disease or Toxicity (Q-TWiST) analysis of CPX-351 versus 7 + 3 in older adults with newly diagnosed high-risk/secondary AML. Cortes, JE., Lin, TL., Uy, GL., et al.[2021]

In a study of 195 patients treated with CPX-351 and 160 patients treated with the conventional 7+3 therapy, CPX-351 was associated with a significantly shorter hospital length of stay (LOS), averaging 183.7 days compared to 197.1 days for 7+3 (p<0.001).

Despite the shorter LOS with CPX-351, the use of supportive care, such as blood products and anti-infectives, was similar between the two treatment groups, indicating that CPX-351 may offer resource advantages without compromising care.
