What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying a type of blood cancer called Acute Myeloid Leukemia (AML). The study is specifically for patients who have been newly diagnosed with a subtype of AML that does not have a certain genetic mutation known as FLT3-ITD. The main treatment being tested in this study is a medication called Quizartinib, which is taken as a film-coated tablet. Quizartinib is being compared to a placebo, which looks like the real medication but does not contain any active ingredients. The study also involves standard chemotherapy treatments, which include medications like Cytarabine, Daunorubicin, and Idarubicin, all of which are given through an intravenous infusion, meaning they are administered directly into a vein.

The purpose of the study is to see how effective Quizartinib is when used alongside these standard chemotherapy treatments. Participants will receive either Quizartinib or a placebo in combination with chemotherapy during the initial treatment phase, known as induction, and the follow-up phase, known as consolidation. After these phases, participants will continue to receive Quizartinib or placebo as a maintenance therapy for up to 36 cycles, which helps to keep the cancer from returning. The study will monitor participants over time to see how long they live and how well they respond to the treatment.

Throughout the study, participants will have regular check-ups and tests to monitor their health and the effects of the treatment. The study aims to provide valuable information on whether adding Quizartinib to standard chemotherapy can improve outcomes for patients with newly diagnosed FLT3-ITD negative AML. This research could potentially lead to better treatment options for people with this type of leukemia.

The research process

The trial runs in 3 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Induction phase

    The induction phase involves the administration of chemotherapy to treat acute myeloid leukemia (AML).

    Medications used include daunorubicin hydrochloride and cytarabine, both administered through intravenous infusion.

    The goal is to achieve a complete response (CR) or complete response with incomplete blood count recovery (CRi).

  2. Step 2

    Consolidation phase

    The consolidation phase begins if a complete response (CR) or CRi is achieved in the induction phase.

    This phase involves further chemotherapy to eliminate any remaining cancer cells.

    The treatment must start within 60 days of the last induction cycle.

  3. Step 3

    Maintenance phase

    The maintenance phase involves the administration of quizartinib or a placebo.

    Quizartinib is taken orally in the form of film-coated tablets.

    This phase aims to maintain remission and is conducted for up to 36 cycles.

    Eligibility for this phase requires less than 5% blasts in the bone marrow and specific blood count levels.

  • Must be a candidate for standard "7+3" induction chemotherapy, as assessed by the investigator.
  • Must have required baseline laboratory data within 7 days before starting the trial drug.
  • If a woman of childbearing potential, must have a negative pregnancy test at the start of the trial and agree to use highly effective birth control during the trial and for 7 months after the last dose of the study drug.
  • Female participants must not donate or retrieve eggs for personal use from the start of the trial until at least 7 months after the last dose of the study drug.
  • If male, must be surgically sterile or agree to use highly effective birth control during the trial and for 4 months after the last dose of the study drug or 6 months after the last dose of chemotherapy, whichever is later.

Investigated drugs

Quizartinib is a medication being studied for its potential to help treat adults with a specific type of blood cancer called Acute Myeloid Leukemia (AML). In this trial, it is given to patients along with standard chemotherapy treatments. The goal is to see if adding quizartinib can improve the overall survival of patients who have been newly diagnosed with a form of AML that does not have a certain genetic mutation known as FLT3-ITD. Quizartinib is used during the initial treatment phase, known as induction, and the follow-up phase, known as consolidation. It is also given as a maintenance therapy to help keep the cancer from coming back.

What is already known about the treatment

Quizartinib – Quizartinib is administered orally and is currently being studied in clinical trials for its effectiveness in treating acute myeloid leukemia (AML), specifically in patients with newly diagnosed FLT3-ITD negative AML. It is being evaluated in combination with standard induction and consolidation chemotherapy, followed by maintenance therapy. Quizartinib works by inhibiting certain proteins involved in the growth and survival of cancer cells, particularly targeting the FLT3 receptor, which is often mutated in AML. It is classified as a tyrosine kinase inhibitor, a type of targeted cancer therapy.

Investigated diseases

Acute Myeloid Leukemia – Acute myeloid leukemia (AML) is a type of cancer that starts in the blood-forming cells of the bone marrow. It progresses rapidly, leading to the accumulation of abnormal white blood cells that interfere with the production of normal blood cells. This can result in symptoms such as fatigue, frequent infections, and easy bruising or bleeding. AML is characterized by the presence of immature cells called myeloblasts in the blood and bone marrow. The disease can affect people of all ages but is more common in adults. It requires prompt medical attention due to its fast progression.
