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
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.
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.
