Item 7.01 Regulation FD Disclosure

LabCorp^® (NYSE: LH), a leading global life sciences company that is deeply integrated in guiding patient care, today announced a new companion diagnostic called therascreen^®PIK3CA PCR mutation analysis, which is now available through LabCorp and its Integrated Oncology specialty laboratory.

The test, developed by QIAGEN (NYSE: QGEN, Frankfurt Stock Exchange: QIA), a world leader in Sample to Insight solutions for molecular testing, identifies whether a patient has the specific gene mutation that is a prerequisite for treatment with Piqray® (aplelisib), a new therapy from Novartis for the treatment of postmenopausal women and all men with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-), PIK3CA-mutated, advanced or metastatic breast cancer, as detected by an FDA-approved test following progression on or after an endocrine-based regimen. Piqray, in combination with fulvestrant, and therascreen PIK3CA PCR mutation analysis assay received approval from the U.S. Food and Drug Administration (FDA) on May 24, 2019. LabCorp is able to make the test available quickly after FDA approval through its participation in QIAGEN’s Day-One Lab Readiness program, under which LabCorp began test validation and development of operating protocols while the test was under regulatory review and is therefore able to make the test available to patients just two weeks after approval.
