* BRACAnalysis CDx has been approved by the FDA for patients with breast and ovarian cancer who are or may become eligible for treatment with the PARP inhibitor Lynparza® (olaparib). BRACAnalysis CDx can also identify patients with ovarian cancer who may experience enhanced progression-free survival (PFS) from Zejula® (niraparib) maintenance therapy. myRisk, myChoice HRD and BRACAnalysis have not been reviewed or approved by the FDA.1,2

Breast Cancer Publications

In the OlympiAD Trial, in patients with HER2-negative metastatic breast cancer and a germline BRCA mutation, olaparib monotherapy provided a significant benefit over standard therapy by reducing the risk of disease progression or death by 42%. This practice-changing evidence highlights the need for the identification and testing of all appropriate patients for hereditary breast cancer to identify the BRCA mutation carriers in order to inform therapeutic decisions. Additionally, trials such as TNT and GeparSixto highlight the clinical utility of knowing BRCA1/2 status in patients when making treatment decisions related to DNA-damaging chemotherapy. Explore these publications to learn more about how BRCA1/2 can impact treatment decisions related to PARP inhibitor therapy and DNA-damaging chemotherapy.4

How Does Testing Impact Treatment Decisions Related to PARP Inhibitors and DNA Damaging Agents?

  1. Intended Use: BRACAnalysis CDx® is an in vitro diagnostic device intended for the qualitative detection and classification of variants in the protein coding regions and intron/exon boundaries of the BRCA1 and BRCA2 genes using genomic DNA obtained from whole blood specimens collected in EDTA. Single nucleotide variants and small insertions and deletions (indels) are identified by polymerase chain reaction (PCR) and Sanger sequencing. Large deletions and duplications in BRCA1 and BRCA2 are detected using multiplex PCR.

    Results of the test are used as an aid in identifying breast and ovarian cancer patients with deleterious or suspected deleterious germline BRCA variants, who are or may become eligible for treatment with Lynparza® (olaparib). Detection of deleterious or suspected deleterious germline BRCA variants by the BRACAnalysis CDx test in ovarian cancer patients is also associated with enhanced progression-free survival (PFS) from Zejula® (niraparib) maintenance therapy. This assay is for professional use only and is to be performed only at 320 Wakara Way, Salt Lake City, UT 84108.
