What is this trial about?

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

This clinical trial studies the treatment of Acute Myeloid Leukemia (AML), a type of blood and bone marrow cancer. The study examines a combination therapy using two medications: liposomal annamycin and cytarabine. This treatment approach is being investigated for patients who have either never received treatment before or whose disease has returned after initial therapy.

The purpose of this research is to determine the safety of this drug combination and find the most appropriate dose for treating AML. The treatment involves receiving both medications through intravenous infusions, which means the drugs are delivered directly into the bloodstream through a vein.

During the study, patients will receive a combination of liposomal annamycin and cytarabine as part of their cancer treatment. The medications will be given according to a specific schedule, and patients will be monitored regularly to evaluate how well they respond to the treatment and to check for any side effects. The study will assess various outcomes, including whether the treatment reduces the number of cancer cells in the bone marrow and improves blood cell counts.

The research process

The trial runs in 6 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial assessment

    Your diagnosis of acute myeloid leukemia (AML) will be confirmed through bone marrow examination or blood test showing more than 5% myeloblasts.

    Laboratory tests will be performed to check your liver and kidney function.

    A pregnancy test will be required for women of childbearing potential within 72 hours before starting treatment.

  2. Step 2

    Treatment preparation

    You must not have received any chemotherapy, radiation, or major surgery within 2 weeks before starting the study treatment.

    If you have had any investigational therapy, it must have been completed at least 4 weeks before starting this treatment.

  3. Step 3

    Treatment administration

    You will receive two medications through intravenous infusion:

    The first medication is liposomal annamycin, a new form of cancer treatment

    The second medication is cytarabine, a standard treatment for AML

    Both medications will be given directly into your bloodstream through an IV line

  4. Step 4

    Monitoring and evaluation

    Your bone marrow and blood will be regularly examined to check:

    The number of cancer cells (blasts) in your bone marrow

    Your blood cell counts, including white blood cells and platelets

    Your liver and kidney function

  5. Step 5

    Treatment response assessment

    Your response to treatment will be evaluated based on:

    Reduction of cancer cells to less than 5% in bone marrow

    Recovery of normal blood cell counts

    Possibility of proceeding to stem cell transplantation if appropriate

  6. Step 6

    Follow-up period

    You will need to use effective contraception during the entire study period

    Women must continue contraception for 6 months after treatment ends

    Men must continue contraception for 3 months after treatment ends

    Regular monitoring will continue throughout the study period, which may last until June 2025

Who can join the trial?

9 criteria

  • You must be at least 18 years old to participate
  • You must have a confirmed diagnosis of Acute Myeloid Leukemia (AML) through either: - A bone marrow test, or - A blood test showing more than 5% myeloblasts (immature blood cells)
  • You must either: - Have not received any previous treatment for AML, or - Have had unsuccessful previous treatment with more than 5% blasts in bone marrow
  • If you are a woman who can become pregnant, you must have a negative pregnancy test within 72 hours before starting the study
  • Both men and women must use effective birth control during the study: - Women must continue birth control for 6 months after the study - Men must continue birth control for 3 months after the study
  • Your performance status (ability to perform daily activities) must be rated 0 to 2 on the ECOG scale, where 0 is fully active and 2 means you can still care for yourself but cannot work
  • You must not have received: - Any chemotherapy, radiation, or major surgery within 2 weeks before the study - Any experimental treatments within 4 weeks before the study
  • Your liver and kidney function tests must be within acceptable ranges: - Bilirubin levels near normal range - Liver enzymes less than 2.5 times normal - Kidney function (creatinine) less than 2 times normal

Investigated drugs

  • Liposomal Annamycin

    is a medication being studied for the treatment of Acute Myeloid Leukemia (AML). It is a special form of annamycin that is enclosed in tiny fat particles called liposomes, which helps deliver the medication more effectively to cancer cells.

  • Cytarabine

    (also known as Ara-C or cytosine arabinoside) is a chemotherapy medication commonly used to treat various types of blood cancers, including Acute Myeloid Leukemia. It works by interfering with the DNA of cancer cells, preventing them from growing and multiplying.

What is already known about the treatment

  • Liposomal Annamycin

    A specialized form of annamycin, delivered through a liposomal formulation for intravenous administration in cancer treatment. This investigational drug belongs to the anthracycline class of chemotherapy medications and is being studied for treating Acute Myeloid Leukemia (AML). The liposomal delivery system helps to enhance the drug's effectiveness while potentially reducing side effects common to traditional anthracyclines, working by interfering with DNA replication in cancer cells to prevent their growth and spread.

  • Cytarabine

    A widely used chemotherapy medication administered intravenously for treating various types of blood cancers, particularly Acute Myeloid Leukemia (AML). It belongs to the antimetabolite class of drugs and works by interfering with DNA synthesis to prevent cancer cell growth. Cytarabine, also known as Ara-C or cytosine arabinoside, is a standard component of many AML treatment regimens and has been well-established in medical literature as a fundamental therapy for leukemia treatment.

Investigated diseases

Acute Myeloid Leukemia - A type of blood and bone marrow cancer that develops when the body produces abnormal white blood cells called myeloblasts. These abnormal cells build up in the bone marrow and interfere with the production of normal blood cells. The disease progresses rapidly, causing a decrease in healthy blood cells, including red blood cells, platelets, and normal white blood cells. As the leukemia cells multiply, they crowd out healthy cells in the bone marrow and can spread to other parts of the body. This condition affects the body's ability to fight infections and maintain normal blood circulation.
