Nab-Paclitaxel and Atezolizumab Before Surgery in Treating Patients With Triple Negative Breast Cancer



This phase II trial studies how well nab-paclitaxel and atezolizumab before surgery work in treating patients with triple negative breast cancer (breast cancer cells that do not have estrogen receptors, progesterone receptors, or large amounts of human epidermal growth factor receptor 2 protein). Drugs used in chemotherapy, such as nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nab-paclitaxel and atezolizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. This drug combination before surgery may be an effective treatment for triple negative breast cancer.

    Trial Purpose

    The goal of this clinical research study is to learn if receiving MPDL3280A and abraxane
    (nab-paclitaxel) in combination before surgery and MPDL3280A alone after surgery can help to
    control breast cancer. The safety of this study drug combination will also be studied.

    Detailed Description

    Study Drug Administration:

    Each study cycle is 21 days. You will receive the study drugs in 2 sets of 4 cycles (4
    cycles before surgery and 4 cycles after surgery).

    You will receive MPDL3280A by vein over about 30 minutes on Day 1 of each cycle before and
    after surgery.

    You will receive nab-paclitaxel by vein over about 30 minutes on Day 1 of Cycles 1-4 before

    If you have side effects, the study doctor may decide to lower your dose of study drugs or
    have you stop taking the drugs. You may be able to restart the study drug later at the same
    or a lower dose. The study doctor will discuss this with you.

    Study Visits:

    On Day 1 of all cycles:

    - You will have a physical exam.

    - Blood (about 2 tablespoons) will be drawn for routine tests.

    - During Cycle 3, you will have an ultrasound of your breast(s) before surgery.

    - During Cycle 3, blood (about 1 tablespoon each time) will be drawn before surgery and
    at the time of surgery.

    Within 6 weeks after you have received 4 cycles of study drugs, you will have surgery as
    part of your standard of care and part of the tumor tissue that is removed during surgery
    will be collected for biomarker testing. You will be given a surgery consent form that
    describes the procedure and its risks.

    On Day 21 of Cycle 8, blood (about 1 tablespoon) will be drawn for biomarker testing.

    Length of Treatment:

    You may receive the study drugs for about 4 cycles before your surgery and about 4 cycles
    after your surgery (8 cycles total). You will no longer be able to take the study drug, if
    intolerable side effects occur, or if you are unable to follow study directions. You may be
    able to continue taking the study drugs if the disease gets worse if the doctor thinks it is
    in your best interest.

    Your participation on the study will be over after follow-up.


    Every 6 months for up to 3 years, you will either have a clinic visit or you will be called
    by a member of the study staff and asked how you are doing. If you are called, each call
    should last about 15-20 minutes.

    This is an investigational study. MPDL3280A is not FDA approved or commercially available.
    It is currently being used for research purposes only. Nab-paclitaxel is FDA approved and
    commercially available for the treatment of metastatic (has spread) breast cancer. The
    study doctor can explain how the study drug combination is designed to work.

    Up to 37 participants will be enrolled in this study. All will take part at MD Anderson.
