  • Research summary

    This study is looking at the safety and effectiveness of a new medicine called Elritercept (TAK-226) compared to Epoetin alfa in adults with a mild bone marrow disorder called lower-risk myelodysplastic syndrome (LR-MDS). People with LR-MDS often have anaemia (low red blood cells) and need blood transfusions. Current treatment options are limited, so researchers are exploring better solutions.

    Study Medications:
    Elritercept (TAK-226): A lab-made protein that helps bone marrow make more red blood cells by blocking natural proteins that slow blood cell production.
    Epoetin alfa: A commonly used medicine that stimulates red blood cell production.

    How Treatment Is Assigned
    Patients will have a 50% chance of being randomly assigned (like flipping a coin) to one of two groups:
    Elritercept (TAK-226): Given once every 28 days (monthly) by injection under the skin.
    Epoetin alfa: Given once every 7 days (weekly) by injection under the skin.

    Study Timeline
    The total time the participant spends in the study may vary. It depends on how they respond to the treatment and whether any side effects or other reasons require stopping the study early. The study will consist of the following phases:
    Screening: Up to 42 days before starting treatment.
    Treatment: At least 24 weeks (6 months), then the participants condition will be checked and treatment may continue.
    Safety Follow-Up: Visits at 1 and 2 months after treatment ends to check for any ongoing effects.
    Survival Follow-Up: Contact every 3 months to ask about new treatments and health updates.

    Approximately 210 to 300 patients will be participating in this study at about 150 sites in 28 countries across the world including the United Kingdom.
