  • Research summary

    Multiple Myeloma (MM) is a cancer that affects
    plasma cells, a type of white blood cell that
    helps protect the body by releasing proteins
    called antibodies that fight infections. Around
    the world, MM causes around 160,000 new
    cases and 106,000 deaths per year. In patients
    with MM, affected plasma cells, known as
    myeloma, are shown to have more molecules
    called B-cell maturation antigen (BCMA) than
    normal plasma cells. Despite recent advances in
    treatment, there is still no cure and almost all
    patients, even those who initially respond to
    treatment, are expected to have MM return.
    PF-06863135 is a new investigational drug
    being developed to treat MM that binds to a
    protein called CD3 on T-cells (a type of
    immune cell) and BCMA on myeloma cells,
    which causes the T-cells to kill the myeloma
    cells.
    The purpose of the study is to learn more about
    whether PF-06863135 can provide benefit to
    participants with MM who are resistant at least
    one proteasome-inhibitor, one
    immunomodulatory drug and one anti-CD38
    monoclonal antibody, which are all other
    specific therapies to treat MM.
    Because it is unknown how previous treatment
    with BCMA-directed therapy (targeting BCMA on myeloma cells to treat MM) will affect how
    PF-06863135 works, this study will enrol one
    group with participants who have not
    previously received a BCMA-directed therapy
    (Cohort A) and one group with participants who
    have received previous treatment with BCMAdirected
    therapy (Cohort B).
    The study is being done at about 60 different
    study sites in up to 10 countries. A maximum of
    around 150 participants will be enrolled and
    treated, including a total of around 90
    participants in Cohort A and around 60
    participants in Cohort B.
    At the start of study participation, participants
    receive PF-06863135 once every week.
    Participants could remain in the study for at least
    2 years.
