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.
Using the right test to determine PD-L1 status for immunotherapy options is important. VENTANA PD-L1 (SP142) Assay* is the first and only FDA-approved test for TECENTRIQ in triple–negative breast cancer (TNBC), urothelial carcinoma (UC) and non-small cell lung cancer 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.
*In the US only available on the BenchMark ULTRA instrument.
VENTANA PD-L1 (SP142) Assay is a qualitative immunohistochemical assay using rabbit monoclonal anti-PD-L1 clone SP142 intended for use in the assessment of the programmed death-ligand 1 (PD-L1) protein in tumor cells and tumor infiltrating immune cells in the formalin-fixed, paraffin-embedded (FFPE) tissues indicated below stained with OptiView DAB IHC Detection Kit and OptiView Amplification Kit on a BenchMark ULTRA 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.
VENTANA PD-L1 (SP142) Assay is indicated as an aid in identifying patients for treatment with the therapies for the respective cutoffs listed in Table 1 in accordance with the approved therapeutic product labeling.

Table 1. Companion diagnostic indications for the VENTANA PD-L1 (SP142) Assay.
|Indication for use||Therapy
||≥ 5% IC
|Triple–Negative Breast Carcinoma (TNBC)
||≥ 1% IC
|Non-Small Cell Lung Cancer (NSCLC)||TECENTRIQ||≥ 50% TC or ≥ 10% IC|
Depending on therapeutic setting, PD-L1 expression in ≥ 50% TC or ≥ 10% IC determined by VENTANA PD-L1 (SP142) Assay in non-small cell lung cancer (NSCLC) patients may be associated with enhanced overall survival from TECENTRIQ (atezolizumab). Refer to the approved therapeutic product labeling for further information.
Test results of this product should be interpreted by a qualified pathologist in conjunction with histological examination, relevant clinical information, and proper controls.
