Today’s announcement follows the U.S, wie die Roche mitteilt.
Food and Drug Administration approval of the assay in March 2019 as the first companion diagnostic to identify triple-negative breast cancer patients eligible for the Tecentriq combination. A diagnosis of triple-negative breast cancer means that the three most common proteins associated with breast cancer growth – estrogen receptor, progesterone receptor and HER2/neu – are not expressed on the tumour.Launched in 2016, the VENTANA PD-L1 (SP142) Assay is the primary diagnostic assay within the Tecentriq clinical development program and was used to enroll and stratify patients in Tecentriq clinical trials.
It was the enrollment assay used in the IMpassion130 trial, the first positive phase III immunotherapy regimen study in triple-negative breast cancer. The assay was the first to evaluate patient PD-L1 biomarker status using immune cell staining and scoring within the tumour microenvironment.8The VENTANA PD-L1 (SP142) Assay is available on the fully automated BenchMark IHC/ISH series instruments and uses the OptiView DAB IHC Detection Kit with OptiView Amplification Kit.
The VENTANA PD-L1 (SP142) Assay performs specific staining of tumour cells and immune cells. The assay was previously approved by the FDA and CE marked for use as a companion diagnostic in urothelial carcinoma (UC)5 and as a predictive assay in non-small cell lung cancer (NSCLC) with Tecentriq.
See the Tecentriq product label for more information on PD-L1 expression levels in therapeutic guidance for various cancer indications.Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1, which is expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the activation of T cells.
Tecentriq is a cancer immunotherapy that has the potential to be used as a foundational combination partner with other immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers. The development of Tecentriq and its clinical programme is based on our greater understanding of how the immune system interacts with tumours and how harnessing a person’s immune system combats cancer more effectively.Roche is the world’s largest biotech company, with truly differentiated medicines in oncology, immunology, infectious diseases, ophthalmology and diseases of the central nervous system.
