  • Research summary

    The aim of this study is to test a new drug, PPSGG,
    that might help patients with anti-MAG neuropathy.
    At the moment, there is no treatment that is
    licenced for use in the UK. The medicines used
    currently to treat anti-MAG neuropathy are licenced
    for other conditions, and are not that effective and
    have various side effects. Anti-MAG antibodies in the
    blood cause the neuropathy in anti-MAG
    paraproteinaemic peripheral neuropathy. The
    purpose of this drug is to reduce or even eliminate
    the level of the anti-MAG antibodies in the blood
    that cause the neuropathy in anti-MAG neuropathy.
    The drug is not a chemotherapy. The drug acts by
    specifically absorbing the anti-MAG antibodies only
    from the blood and carrying them away. If the levels
    of anti-MAG autoantibodies are low, the patient
    could have better outcome. An increase in these
    autoantibodies normally indicates that the disease is
    worsening.
    The main aim of this study is to determine how safe
    it is, to see how well PPSGG works, to see how it is
    broken down in the body after one dose and several
    doses, as well as to see how it affects patient
    outcome.
    This study will consist of 2 parts or phases. The first
    phase of the study is called the Single Ascending
    Dose (SAD) phase. Each patient in each cohort will
    be given a single dose of drug, with the dose
    increasing in each cohort. All patients will receive
    the study drug. The second phase of the study is
    called the Multiple Ascending Dose (MAD) phase. In
    the MAD phase the patients will receive either the
    study drug or a placebo (dummy) drug and neither
    participants nor the treating doctor will know which
    they have received (a double blind study). Several
    doses of drug will be given to each patient and the
    dose of drug will increase through the study.
