  • Research summary

    This is a Phase 3 open-label study comparing the effectiveness and safety of bb2121 versus standard treatment options in patients with relapsed and refractory Multiple Myeloma.

    There have been improved outcomes in newly diagnosed and relapsed MM patients, however mostly all MM patients will progress/relapse and need additional treatment.

    bb2121 is a new type of therapy known as a CAR (Chimeric antigen receptor) T cell therapy. T cells are white blood cells which form part of the immune system. bb2121 therapy involves modifying a patient's own T cells so that they can recognise and destroy multiple myeloma cells.

    To create the bb2121 drug product, some of the T cells will be collected from the patient's blood in a procedure called leukapheresis. A new gene will be inserted into the patient's T cells using a genetically modified virus. bb2121 will then be given back to patients intravenously.

    Approximately 381 patients (14 in the UK) across 12 countries will be randomised between Arm A or Arm B:

    • 254 patients will be randomised to receive Treatment Arm A: bb2121
    • 127 patients will be randomised to receive Treatment Arm B: standard courses of treatment dependent on the patient’s most recent anti-myeloma treatment
    The standard treatment options are:
    - Daratumumab (DARA) in combination with pomalidomide (POM) and low-dose dexamethasone (dex) (DPd)

    OR

    - DARA in combination with bortezomib (BTZ) and low-dose dex (DVd)

    OR

    - Ixazomib (IXA) in combination with lenalidomide (LEN) and low-dose dex (IRd)

    Study procedures will include: physical examinations, blood and urine tests, radiological scans and vital sign checks.

    Study patients must be aged over 18 with Relapsed/Refractory MM and have received 2 to 4 prior treatments including DARA, an immunomodulator drug and a PI. The patient must have documented disease progression during or within 60 days after the last therapy.
