Regulation FD Disclosure

On October 2, 2015, Laboratory Corporation of America® Holdings (LabCorp®) (LH: NYSE) announced the nationwide availability of a new FDA-approved companion diagnostic, the PD-L1 IHC 22C3 pharmDx assay by Dako, an Agilent Technologies company, to assess the eligibility of non-small cell lung cancer (NSCLC) patients for treatment with pembrolizumab (Keytruda).
According to the American Cancer Society, lung cancer is the leading cause of cancer death in the U.S. and is the second most commonly diagnosed cancer with an estimated 221,200 new cases diagnosed in 2015. The vast majority of patients exhibit the non-small cell subtype, representing 80-85% of patients, and over half of these patients are diagnosed with metastatic or advanced disease at initial presentation. Data from the KEYNOTE trial recently presented at the American Association for Cancer Research Annual Meeting and published in the New England Journal of Medicine demonstrated that PD-L1 expression in at least 50% of non-small cell lung tumor cells correlated with improved response rates and progression free survival in patients treated with Keytruda.
