Trial Summary

What is the purpose of this trial?

This study will compare the effects of Quizartinib versus placebo in combination with chemotherapy in participants with newly diagnosed FMS-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) negative acute myeloid leukemia (AML).

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that treatment with all-trans retinoic acid (ATRA) must be discontinued before starting induction chemotherapy.

What data supports the effectiveness of the drug Quizartinib combined with chemotherapy for leukemia?

Research shows that Quizartinib, when combined with chemotherapy, improved survival and response rates in patients with certain types of acute myeloid leukemia (AML), particularly those with FLT3-ITD mutations. In one study, patients receiving Quizartinib with low-dose chemotherapy had significantly better survival rates compared to those receiving chemotherapy alone. ^{1 2 3 4 5}

Is the combination of Quizartinib and chemotherapy safe for humans?

Quizartinib combined with chemotherapy has been studied for safety in people with acute myeloid leukemia (AML). Some patients experienced serious side effects like febrile neutropenia (fever with low white blood cells), pericardial effusion (fluid around the heart), and QT prolongation (heart rhythm changes). However, the treatment was generally tolerable, and most side effects were manageable. ^{1 3 6 7 8}

What makes the drug Quizartinib + Chemotherapy unique for treating leukemia?

Quizartinib, when combined with chemotherapy, offers a novel approach for treating leukemia by targeting specific mutations in cancer cells, potentially improving outcomes for patients with certain types of leukemia that are resistant to other treatments. ^{9 10 11 12 13}

Treatment Details

Interventions

• Chemotherapy (Chemotherapy)
• Quizartinib (Tyrosine Kinase Inhibitor)

Trial Overview The study is testing whether adding Quizartinib, an experimental drug, to standard chemotherapy is more effective than adding a placebo in patients with AML who do not have the FLT3-ITD mutation.

Participants will receive quizartinib at 60 mg/day orally once daily for 14 days starting after the completion of chemotherapy in Induction and Consolidation Phase. In the Maintenance Phase, participants will receive placebo at 60 mg/day orally once daily for up to 36 cycles (28-day cycle)

Group II: Arm A: Quizartinib + Chemotherapy Experimental Treatment 2 Interventions

Participants will receive quizartinib at 60 mg/day orally once daily for 14 days starting after the completion of chemotherapy in Induction and Consolidation Phase. In the Maintenance Phase, participants will receive quizartinib at 60 mg/day orally once daily for up to 36 cycles (28-day cycle)

Group III: Arm B: Placebo + Chemotherapy Placebo Group 2 Interventions

Participants will receive placebo at 60 mg/day orally once daily for 14 days starting after the completion of chemotherapy in Induction and Consolidation Phase. In the Maintenance Phase, participants will receive placebo at 60 mg/day orally once daily for up to 36 cycles (28-day cycle)

Findings from Research

Quizartinib, a selective FLT3 inhibitor, was found to be well tolerated at a dose of 60 mg/m²/day in children with relapsed acute leukemia, showing a favorable toxicity profile during intensive chemotherapy.

The treatment resulted in significant biological activity, with complete inhibition of FLT3 phosphorylation in all patients and promising response rates, particularly in those with FLT3-ITD mutations, indicating potential for further testing in this population.

The combination of paclitaxel and quizartinib significantly reduces the proliferation of the MV4-11 leukemia cell line and increases apoptosis compared to either drug alone, indicating a synergistic effect.

This combination therapy works by inhibiting the FLT3/STAT5 signaling pathway, as evidenced by lower levels of phosphorylated FLT3 and STAT5 proteins in the combination group.

In a phase III trial, the FLT3 inhibitor quizartinib showed a survival benefit compared to traditional chemotherapy in patients with relapsed or refractory FLT3-mutant acute myeloid leukemia.

The promising results from quizartinib suggest it may become a first-line treatment option for this type of leukemia, pending outcomes from ongoing studies.

Small molecule inhibitors (SMIs) for acute myeloid leukemia (AML) can be more tolerable than traditional chemotherapy, but they have a high potential for drug-drug interactions (DDIs) that can affect treatment success, especially since AML patients often take multiple medications.

CYP3A4 is the main enzyme that metabolizes these SMIs, and strong inhibitors or inducers of this enzyme can lead to increased toxicity or decreased efficacy, necessitating careful monitoring and possible dose adjustments for drugs like venetoclax and quizartinib.

In a phase 1 study involving 13 patients with FLT3-ITD-mutated acute myeloid leukemia (AML) after allogeneic hematopoietic-cell transplant, quizartinib showed acceptable tolerability as a maintenance therapy, with 77% of subjects receiving it for over a year.

The study indicated early evidence of reduced relapse rates with quizartinib maintenance therapy, although some patients experienced significant adverse events, including neutropenia and anemia.

Quizartinib is an effective treatment for patients with FLT3-ITD acute myeloid leukemia (AML), as it inhibits the FLT3 gene activity, leading to tumor cell death, and has shown promise in clinical trials for relapsed or refractory cases.

The drug has received breakthrough therapy designation from the FDA, highlighting its potential, but further studies are necessary to assess its safety, efficacy in combination with other treatments, and to address its side effects.

Recent advancements in leukemia treatments have led to high cure rates, such as over 90% for hairy cell leukemia with cladribine and rituximab, and 80-90% for acute promyelocytic leukemia using all-trans retinoic acid and arsenic trioxide.

Chronic lymphocytic leukemia, once considered incurable, may now be potentially curable with targeted therapies like Bruton tyrosine kinase inhibitors and venetoclax, showcasing the significant progress in leukemia treatment options.

Amphotericin B can enhance the effectiveness of chemotherapy drugs like actinomycin D, adriamycin, and vincristine against AKR leukemia, even in cells that have developed resistance to these treatments.

While resistance to actinomycin D developed quickly in leukemia cells, resistance to vincristine and adriamycin occurred more slowly; however, amphotericin B still improved the efficacy of these drugs against resistant cells, although the enhancement decreased as resistance increased.
