Predictive IHC assay
VENTANA PD-L1 predictive assays identify patients who are most likely to respond to specific therapies, generating results you can trust so that you can make timely diagnostic decisions and therapeutic choices. We support your expertise by providing you with the tools that you need to successfully implement these assays into your laboratory and interpret them proficiently.
* VENTANA PD-L1 (SP142) Assay may not be available for some indications and/or cutoffs in all geographies. In Switzerland atezolizumab is approved for non-small cell lung cancer only.
Using the right test to determine PD-L1 status for immunotherapy options is important. VENTANA PD-L1 (SP142) Assay* is the first and only CE-IVD marked test for atezolizumab in triple–negative breast cancer (TNBC) and urothelial carcinoma (UC) and non-small cell lung cancer (NSCLC) patients. This novel assay is also the first to evaluate patient PD-L1 expression using immune cell staining and scoring within the tumor microenvironment, providing you with information that can guide immunotherapy decisions.
Using the right test to determine PD-L1 status for immunotherapy options is important, and the VENTANA PD-L1 (SP142) Assay is the only CE-IVD marked test for atezolizumab. This innovative assay is the first to evaluate patient PD-L1 expression using both tumor cell (TC) and tumor-infiltrating immune cell (IC) staining. Determining a patient’s PD-L1 expression level can give insight to the overall survival that may be achieved from atezolizumab.*
*All randomized patients in a NSCLC phase III study observed benefit from atezolizumab regardless of PD-L1 status.
VENTANA PD-L1 (SP142) Assay is intended for the immunohistochemical assessment of the programmed death-ligand 1 (PD-L1) protein in tumor cells and tumor-infiltrating immune cells in formalin-fixed, paraffin-embedded (FFPE) tissues indicated below stained with OptiView DAB IHC Detection Kit and OptiView Amplification Kit on a BenchMark IHC/ISH instrument.
Determination of PD-L1 status is indication-specific and evaluation is based on either the proportion of tumor area occupied by PD-L1 expressing tumor-infiltrating immune cells (% IC) of any intensity or the percentage of PD-L1 expressing tumor cells (% TC) of any intensity.
| Indication for use | Therapy |
Cutoff |
|---|---|---|

atezolizumab | ≥ 5% IC |
| Triple–Negative Breast Carcinoma (TNBC) |
≥ 1% IC |
|
| Non-Small Cell Lung Cancer (NSCLC) | ≥ 50% TC or ≥ 10% IC |
