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, you cannot be on any other approved or investigational anti-leukemia treatments while participating in this trial.

What data supports the effectiveness of the Decitabine + FLAG-Ida treatment for myeloid malignancies?

Research shows that the combination of Decitabine with FLAG-Ida has been effective in treating acute myeloid leukemia (AML), with studies reporting complete remission rates of over 50% in patients with relapsed or refractory AML. This suggests that the treatment can be effective in managing difficult cases of AML.12345

Is the Decitabine + FLAG-Ida treatment generally safe for humans?

The Decitabine + FLAG-Ida treatment, which includes drugs like cytarabine, idarubicin, and filgrastim, has been studied for safety in people with myeloid malignancies. Common side effects include infections, especially in the lungs, and conditions like mucositis (painful inflammation and ulceration of the mucous membranes) and pulmonary toxicity (lung damage). While some patients experienced severe side effects, the overall safety profile is considered acceptable for high-risk patients.25678

How is the drug Decitabine + FLAG-Ida unique for treating myeloid malignancies?

The combination of Decitabine with FLAG-Ida is unique because it uses Decitabine as an 'epigenetic priming' agent, which means it helps make cancer cells more sensitive to chemotherapy by altering gene expression. This approach is particularly useful for patients with acute myeloid leukemia (AML) who have not responded to other treatments, offering a new option for those with difficult-to-treat cases.3491011

What is the purpose of this trial?

This phase I/II trial studies the safety, side effects, and best dose of decitabine in combination with fludarabine, cytarabine, filgrastim, and idarubicin (FLAG-Ida) and total body irradiation (TBI) followed by a donor stem cell transplant in treating adult patients with cancers of blood-forming cells of the bone marrow (myeloid malignancies) that are at high risk of coming back after treatment (relapse). Cancers eligible for this trial are acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and chronic myelomonocytic leukemia (CMML). Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. The FLAG-Ida regimen consists of the following drugs: fludarabine, cytarabine, filgrastim, and idarubicin. These are chemotherapy drugs that 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. Filgrastim is in a class of medications called colony-stimulating factors. It works by helping the body make more neutrophils, a type of white blood cell. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. TBI is radiation therapy to the entire body. Giving chemotherapy and TBI before a donor peripheral blood stem cell (PBSC) transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets. Giving decitabine in combination with FLAG-Ida and TBI before donor PBSC transplant may work better than FLAG-Ida and TBI alone in treating adult patients with myeloid malignancies at high risk of relapse.

DONORS: Participants undergo apheresis for collection of PBSCs on study. PATIENTS: Patients receive decitabine IV daily over 1 hour on days -12 to -10, -14 to -10, -16 to -10, or -19 to -10, filgrastim SC daily on days -9 to -4, idarubicin IV over 60 minutes daily on days -8 to -6, fludarabine IV over 30 minutes daily on days -8 to -4, cytarabine IV over 2 hours daily on days -8 to -4, and undergo TBI BID on day -1 or 0 OR daily on days -1 and 0 in the absence of disease progression or unacceptable toxicity. Patients then undergo HCT (receive donor PBSCs via infusion) on day 0. Patients also undergo MUGA scan or ECHO during screening, chest X-rays and bone marrow aspiration and/or biopsy during screening and as clinically indicated, and collection of blood samples throughout the study.

Findings from Research

In a phase I trial involving 37 pediatric patients with relapsed/refractory acute myeloid leukemia (R/R AML), the combination of decitabine, vorinostat, and FLAG chemotherapy showed a promising overall response rate of 54%, with 16 patients achieving complete response (CR).
The treatment was well-tolerated with no dose-limiting toxicities, and among those who responded, 90% achieved minimal residual disease (MRD) negativity, leading to a significantly higher two-year overall survival rate of 75.6% for MRD-negative patients compared to 17.9% for those with residual disease.

In a study of 21 patients with refractory or recurrent acute myeloid leukemia (R/R AML), the triple therapy of decitabine, idarubicin, and cytarabine (D-IA) resulted in a 47.6% complete remission rate after one treatment cycle, indicating significant efficacy.
The treatment was generally well tolerated, with no treatment-related mortalities reported, although common side effects included hematological toxicity and infections, suggesting a manageable safety profile.

In a study of 42 adult patients with relapsed or refractory acute myeloid leukemia (AML) treated with the FLAG ± Ida chemotherapy regimen, the complete remission (CR) rate was 47.6%, which aligns with historical rates of 52% to 63%.
The median overall survival (OS) for patients achieving CR was not reached, with an estimated 48-month survival rate of 56%, indicating that FLAG ± Ida remains an effective salvage treatment for R/R AML, despite common adverse effects like pancytopenia and infection.
