About the Study
This clinical trial is studying a new combination of drugs to treat , or HER2-low breast cancer in people with an or tumor mutation in , or . The study is looking at whether adding a new drug called axatilimab to treatment with the olaparib (Lynparza) will improve outcomes in people with breast cancer.

People with breast cancer may be eligible if they meet all of the following:
- have or HER2-low breast cancer.
- have hormone receptor positive () or hormone receptor negative (HR-negative) cancers.
- participants with hormone receptor disease must not be eligible for hormone therapy (due to cancer progression or other factors that make them in)
- have an inherited mutation in , , or or a tumor mutation in or .
- have evidence of cancer that can be measured by imaging to track whether or not cancer is responding to treatment.
- have received at least two prior treatments that included chemotherapy, or a type of known as an antibody-drug conjugate.
- must be willing to undergo 3 separate research biopsies.
Additional criteria:
- people with brain or central nervous system spread may participate if:
- they also have spread to other parts of the body that can be measured with imaging.
- they have not had progression of cancer in the brain or central nervous system after treatment for that spread.
- people who are infected with HIV or Hepatitis B or C may participate if their disease is controlled with medication.
- prior treatment with a is allowed as long as the cancer did not get worse while on, or up to a year after treatment.
