Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it mentions that children who have previously received chemotherapy, radiation therapy, or any anti-leukemic therapy are not eligible, except for cytarabine for treating transient myeloproliferative disorder.

What data supports the effectiveness of the drug for treating acute myeloid leukemia in young patients with Down syndrome?

Research shows that children with Down syndrome and myeloid leukemia have better survival rates when treated with less intensive chemotherapy regimens, including drugs like cytarabine and daunorubicin, due to their heightened sensitivity to these drugs. A study reported a 5-year event-free survival rate of 89.9% and overall survival of 93.0% for patients treated with a modified regimen, highlighting the effectiveness of these drugs in this specific group.12345

What safety data exists for chemotherapy treatments in young patients with Down syndrome and acute myeloid leukemia?

Children with Down syndrome treated for myeloid leukemia using reduced-dose chemotherapy have shown favorable survival rates while minimizing toxicity. Common side effects of treatments like Vyxeos, which includes daunorubicin and cytarabine, are hypersensitivity, febrile neutropenia (low white blood cell count with fever), and prolonged neutropenia (low white blood cell count) and thrombocytopenia (low platelet count).13678

What makes this chemotherapy treatment for acute myeloid leukemia in young patients with Down syndrome unique?

This treatment is unique because it combines multiple drugs, including asparaginase and cytarabine, which have shown increased sensitivity in Down syndrome patients, allowing for potentially better outcomes with reduced toxicity compared to standard treatments. The approach also involves optimizing drug dosing and scheduling to improve survival rates while minimizing side effects.135910

What is the purpose of this trial?

This trial studies a chemotherapy treatment that adjusts based on how well patients respond initially. It targets younger patients with Down syndrome who have certain types of blood cancer. The treatment aims to effectively kill cancer cells while reducing side effects.

Eligibility Criteria

This trial is for young patients with Down syndrome who have newly diagnosed acute myeloid leukemia or myelodysplastic syndrome. They must not have received any anti-leukemic therapy except cytarabine for transient myeloproliferative disease, and they should not have promyelocytic leukemia. Patients need to show a certain percentage of blasts in their bone marrow or blood and meet specific diagnostic criteria.

Inclusion Criteria

It has been over 8 weeks since my temporary blood disorder with high blast cells resolved.
I have a new diagnosis of AML with more than 20% bone marrow blasts.
I have Down syndrome confirmed by genetic testing.

Exclusion Criteria

I received my last cytarabine dose for TMD treatment within the last 30 days.
I have been diagnosed with a specific type of leukemia (FAB M3).

Findings from Research

Vyxeos, a liposomal formulation combining daunorubicin and cytarabine, significantly improves overall survival in patients aged 60-75 with untreated high-risk acute myeloid leukemia (AML), showing a median survival of 9.56 months compared to 5.95 months with standard chemotherapy.
The study demonstrated that Vyxeos not only enhances survival rates but also increases the likelihood of patients undergoing hematopoietic stem cell transplantation, which is crucial for potentially curing AML.

CPX-351, a liposomal-encapsulated combination of daunorubicin and cytarabine, has been approved for treating therapy-related acute myeloid leukemia (tAML) and AML with myelodysplasia-related changes (AML-MRCs), showing improved overall survival and remission rates in older patients compared to the traditional '7 + 3' treatment.
In a Phase III trial involving patients aged 60-75, CPX-351 demonstrated higher rates of complete remission and event-free survival, suggesting that its fixed 5:1 drug ratio may enhance efficacy in these challenging subgroups of AML.

Vyxeos (CPX-351) received FDA approval for treating adults with newly diagnosed therapy-related acute myeloid leukemia (t-AML) or acute myeloid leukemia with myelodysplasia-related changes (AML-MRC), based on a study involving 309 patients aged 60-75 that showed improved overall survival (9.6 months vs. 5.9 months with standard treatment).
The safety profile of Vyxeos was comparable to the standard treatment, but it was associated with longer periods of neutropenia and thrombocytopenia, highlighting the need for careful monitoring and a warning against switching between different formulations of daunorubicin and cytarabine during treatment.
