BARD1: Options for Cancer Treatment

Cancer Treatment for People with Inherited BARD1 Mutations

Inherited BARD1 mutations may affect treatment options or eligibility for clinical trials studying which treatments work best. The following are examples of situations where a BARD1 mutation may affect cancer treatment decisions. 

Targeted therapies and BARD1 mutations

PARP inhibitors are a type of targeted therapy that work by blocking a protein used to repair damaged DNA. People with a BARD1 mutation who have been diagnosed with cancer may want to ask their doctor about whether they might benefit from a clinical trial or treatment with a PARP inhibitor. 

Metastatic prostate cancer

The PARP inhibitor, Lynparza (olaparib) has FDA-approval to treat metastatic, castration-resistant prostate cancer in people who have a mutation in BARD1 or other genes linked to a certain type of DNA damage repair. 

Advanced ovarian, fallopian tube or primary peritoneal cancer

Two PARP inhibitors have been approved as first-line maintenance therapy for ovarian cancer based on a tumor biomarker test known as an HRD test ("homologous recombination deficiency"). Cancers that test HRD-positive may be treated with Lynparza (olaparib) in combination with Avastin (bevacizumab) or Zejula (niraparib) alone as maintenance therapy after first-line platinum chemotherapy.

PARP inhibitors or other targeted therapies for advanced cancers with no other treatment options

If you have a BARD1 mutation and advanced cancer that no longer responds to standard therapy, talk with your doctor about tumor testing to learn whether you might benefit from a PARP inhibitor, another targeted therapy or participation in a clinical trial.
