SRS and Olaparaib followed by Durvalumab in Breast Cancer with Brain Metastases
What is the Purpose of this Study?
- Take olaparib twice a day for a week before before SRS and up to 28 days afterward
- Get an infusion (IV) of durvalumab every 21 days in combination with chemotherapy after you finish olaparib + SRS
- Have physical exams and blood draws
- Have imaging done (MRI and CT)
Your study doctor will determine what your chemotherapy regimen should be after you complete SRS.
We are also doing a sub-study for breast cancer patients who are having their brain metastases surgically removed. If you are eligible to join the sub-study rather than the main study, you will also take olaparib for a week before your surgery but you will not get durvalumab in combination with chemotherapy afterward in the same manner as the main study. You might be able to join the main study after you finish the sub-study if you are scheduled for SRS after your surgical resection.
Who Can Participate in this Study?
Adults ages 18+ who:
- Are diagnosed with breast cancer
- Have a newly diagnosed brain metastasis that can be treated with SRS
- Have not participated in a research study that uses durvalumab
- Have not received whole brain radiotherapy
- Are not pregnant

What is Involved?
We are doing this study to find out the highest dose of a drug called olaparib that is safe to give at
the same time as stereotactic radiosurgery (SRS). We also want to see if we can lessen the chance of having your cancer return by following the olaparib + SRS treatment with a combination of chemotherapy and a drug called durvalumab.
