Are PARP Inhibitors Right for Me?

PARP inhibitors are a new type of targeted therapy that represent a major breakthrough in cancer treatment, especially for patients of ovarian cancer and HER2-negative breast cancer who previously had limited treatment options. However, not every patient is a candidate for PARP inhibitors.

Studies have shown that PARP inhibitors are more effective for patients carrying mutations in BRCA genes or other genes associated with homologous recombination repair (HRR) functions. Homologous recombination is a process that repairs damages in our DNA. If a tumor has deficiency in its DNA repair functions, the cancer cells are more likely to be destroyed by PARP inhibitors, making PARP inhibitors more effective.

Evaluate PARP Inhibitors with ACTBRCA® / ACTBRCA® HRD

ACTBRCA® / ACTBRCA® HRD are genetic tests that can determine whether the patient is carrying BRCA mutations or other HRR-related mutations, helping physicians to evaluate whether the patient is likely to benefit from PARP inhibitors. Our tests cover more mutation types compared to common BRCA tests, and provide more complete information for physicians to decide if a PARP inhibitor is right for you.



  • Suitable for: Ovarian cancer patients, breast cancer patients, or other solid tumor patients who wish to use PARP inhibitors

  • Turnaround Time: 14 calendar days

Ask Your Doctor First

It is important to discuss with your doctor first as many factors need to be taken into consideration when making decisions about treatment. If you and your doctor decide that genomic testing is right for you, your doctor will order the test and assist in sending the required samples to our laboratory.
