PIK3CA-11 mutations 12.5% AF cfDNA

Specifically designed for the FDA/CE-IVD approved Qiagen therascreen® PIK3CA RGQ PCR Kit.

PIK3CA mutations occur in approximately 40% of patients with hormone receptor (HR)–positive, human epidermal growth factor receptor 2 (HER2)–negative breast cancer were it is localized mainly on Exons 9 and 20. PIK3CA mutations are highly frequent in other tumor entities like Endometrium, Colon, Urinary tract, Cervix and the large intestine (1-5).

Application Details

The Reference Set of Control was specifically designed for use with the CE-IVD therascreen® PIK3CA RGQ PCR Kit from Qiagen. It contains all mutations the test kit investigates and aligns completely with the protocol of the assay.

The Food and Drug Administration approved alpelisib (PIQRAY®/alpelisib, Novartis Pharmaceuticals Corporation) in combination with fulvestrant for postmenopausal women, and men, with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA-mutated, advanced or metastatic breast cancer as detected by an FDA-approved test following progression on or after an endocrine-based regimen.

The FDA also approved the companion diagnostic test, therascreen® PIK3CA RGQ PCR Kit, (QIAGEN Manchester, Ltd.), to select patients who have PIK3CA mutations in tumor tissue specimens and/or in circulating tumor DNA (ctDNA) isolated from plasma specimens. If the test is negative for PIK3CA mutations in plasma, patients should undergo testing for PIK3CA mutations in tumor tissue.
