What is this trial about?

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

This clinical trial is focused on studying two types of blood cancers: acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). These are serious conditions where the bone marrow does not produce blood cells properly. The treatment being tested in this study is called MP0533, which is given as a solution through an infusion into the veins. This treatment contains substances like sodium dihydrogen phosphate dihydrate, polysorbate 20, and sodium chloride.

The purpose of the study is to explore the safety and how well patients tolerate MP0533, as well as to find the best dose to use in future studies. The study will also look at how effective the treatment is in fighting the cancer. Participants will receive the treatment and be monitored closely to see how their bodies respond. The study will take place over several phases, starting with a small number of patients to determine the safest dose, and then expanding to include more patients to further assess the treatment's effects.

Throughout the study, researchers will keep track of any side effects and changes in the patients' health. The goal is to gather information that could lead to new treatment options for people with AML and MDS. This study is an important step in understanding how MP0533 can be used to help patients with these challenging conditions.

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

    Joining the study

    Upon joining the study, the patient will have signed and dated a written informed consent form. This confirms understanding and agreement to participate in the study.

    The patient must have a diagnosis of relapsed or refractory acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) and meet specific health criteria, including adequate kidney and liver function.

  2. Step 2

    Initial assessment

    An initial assessment will be conducted to evaluate the patient's health status. This includes checking the performance status and life expectancy, as well as ensuring the patient meets all inclusion criteria.

  3. Step 3

    Treatment administration

    The patient will receive the study medication, MP0533, which is a solution for infusion administered intravenously.

    The dosage and frequency will be determined during the study, with the aim to find the safest and most effective dose.

  4. Step 4

    Monitoring and evaluation

    Throughout the study, the patient will be closely monitored for any side effects or changes in health status. This includes regular laboratory tests and vital sign checks.

    The study will assess the safety and tolerability of MP0533, as well as its effectiveness in treating the patient's condition.

  5. Step 5

    Completion of treatment cycle

    At the end of each treatment cycle, the patient's response to the medication will be evaluated. This includes measuring the overall response rate and any changes in the condition.

    The study aims to determine the best overall response, which may include complete remission or partial remission.

  6. Step 6

    Follow-up

    After completing the treatment cycles, the patient will continue to be monitored for any long-term effects or changes in their condition.

    The study will track the duration of response and overall survival, as well as any progression to further treatments such as stem cell transplantation.

Who can join the trial?

10 criteria

  • The patient must have signed and dated a written agreement to participate in the study before any study procedures are done.
  • The patient must have a diagnosis of **relapsed/refractory acute myeloid leukemia (AML)** or **relapsed/refractory myelodysplastic syndrome (MDS/AML)**, based on specific medical guidelines.
  • The patient must be **18 years or older** on the day they sign the agreement to participate.
  • The patient must have a **performance status** of 0 to 2, which is a measure of their ability to carry out daily activities.
  • The patient must have a **life expectancy** of at least 12 weeks, as judged by the study doctor.
  • The patient must have **adequate kidney and liver function**. This means:
    • The kidneys must be able to filter blood at a rate greater than 40 mL/min, unless the condition is related to AML or MDS.
    • The level of **bilirubin** in the blood, a substance made by the liver, must be no more than 2.5 times the normal limit, unless related to AML, MDS, or a condition called Gilbert's syndrome.
    • The levels of certain liver enzymes, **AST** and **ALT**, must be no more than 3 times the normal limit, unless related to AML or MDS.
    • The patient must have a **white blood cell count** of 15G/L or less on the day they receive the trial drug. A medication called hydroxyurea is allowed before this.
    • If the patient is a woman who can have children or a man, they must use **highly effective birth control** during the study.

Who cannot join the trial?

8 criteria

  • Patients who have a different type of cancer than the ones being studied.
  • Patients who have not recovered from previous treatments or surgeries.
  • Patients with severe heart problems.
  • Patients with uncontrolled infections.
  • Patients who are pregnant or breastfeeding.
  • Patients who have a history of other serious medical conditions that could interfere with the study.
  • Patients who are unable to follow the study procedures.
  • Patients who are participating in another clinical trial.

Investigated drugs

MP0533 is an experimental medication being studied for its potential to treat patients with relapsed or refractory acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). The trial aims to determine how safe and tolerable this medication is for patients, as well as to find the most effective dose. Researchers are also looking at how well MP0533 can fight leukemia in these patients.

What is already known about the treatment

MP0533 – This medication is administered intravenously and is currently being studied in clinical trials for its potential use in treating relapsed or refractory acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). It is in the early stages of research, specifically in a phase 1/2a trial, to assess its safety, tolerability, and effectiveness. MP0533 is designed to target specific cancer cells, aiming to reduce their growth and spread by interfering with certain molecular pathways. It falls under the category of targeted cancer therapies, which work by focusing on specific molecules involved in the growth and survival of cancer cells.

Investigated diseases

  • Acute Myeloid Leukemia (AML)

    This is a type of cancer that starts in the blood-forming cells of the bone marrow and quickly progresses to affect the blood. It is characterized by the rapid growth of abnormal white blood cells that accumulate in the bone marrow and interfere with the production of normal blood cells. Symptoms may include fatigue, fever, frequent infections, and easy bruising or bleeding. As the disease progresses, it can spread to other parts of the body, including the lymph nodes, liver, and spleen. AML is known for its aggressive nature and requires prompt medical attention.

  • Myelodysplastic Syndrome (MDS)

    This is a group of disorders caused by poorly formed or dysfunctional blood cells. It occurs when the blood-forming cells in the bone marrow are damaged, leading to a shortage of one or more types of blood cells. People with MDS may experience symptoms such as fatigue, shortness of breath, and increased risk of infections or bleeding. The condition can vary in severity and may progress to acute myeloid leukemia in some cases. MDS is often diagnosed through blood tests and bone marrow examinations.
