Empowering pathologists to answer PD-L1 questions

 

The VENTANA PD-L1 (SP263) assay guides immunotherapy decisions by identifying:

  • Non-small cell lung cancer (NSCLC) patients eligible for treatment with IMFINZITM (durvalumab) 
  • NSCLC patients eligible for treatment with KEYTRUDA® (pembrolizumab)
  • Urothelial carcinoma (UC) patients most likely to benefit from IMFINZITM (durvalumab) 

Non-small cell lung cancer (NSCLC)

 

The VENTANA PD-L1 (SP263) assay expands immunotherapy options for NSCLC patients through equipping pathologists by:

  • Identifying NSCLC patients eligible for treatment with IMFINZI (durvalumab)
  • Identifying NSCLC patients eligible for treatment with KEYTRUDA (pembrolizumab)**
  • Providing robust PD-L1 staining in both tumour cells (TC) and tumour-infiltrating immune cells (IC)†
  • Allowing optimal lung tissue management through PD-L1 testing of archived unstained slides within 12 months

**Based on a method comparison study carried out by AstraZeneca, which compares data from currently available PD-L1 assays, PD-L1 IHC 22C3 pharmDx (used in the clinical studies of KEYTRUDA), PD-L1 IHC 28-8 pharmDx (used in the clinical studies of OPDIVO) and VENTANA PD-L1 (SP263) Assay.

†IC staining with this assay is not used to assess PD-L1 status for KEYTRUDA or OPDIVO in NSCLC.  

Urothelial carcinoma

 

The VENTANA PD-L1 (SP263) assay is the clinical trial enrollment assay for IMFINZI (durvalumab) and the only PD-L1 assay validated to assess UC patient treatment benefit from this PD-L1 inhibitor. Using a validated assay to determine PD-L1 status for immunotherapies is important. VENTANA PD-L1 (SP263) Assay equips pathologists by:

  • Identifying urothelial carcinoma patients most likely to benefit from IMFINZI (durvalumab)
  • Producing robust PD-L1 staining in both tumour cells (TC) and tumour-infiltrating immune cells (IC)
  • Providing access to multiple immunotherapy options for different cancer types.

Reagent catalog

VENTANA PD-L1 (SP263) Assay is intended for the qualitative detection of the programmed death ligand 1 (PD-L1) protein in formalin-fixed, paraffin-embedded (FFPE) non-small cell lung cancer (NSCLC), urothelial carcinoma (UC) tissues stained with OptiView DAB IHC Detection Kit on a BenchMark IHC/ISH instrument.

NSCLC:

PD-L1 expression in tumour cell (TC) membrane as detected by VENTANA PD-L1 (SP263) Assay in NSCLC is indicated as an aid in identifying patients for treatment with IMFINZI™ (durvalumab).

 

PD-L1 expression in tumour cell (TC) membrane as detected by VENTANA PD-L1 (SP263) Assay in NSCLC is indicated as an aid in identifying patients for treatment with KEYTRUDA® (pembrolizumab).


PD-L1 expression in tumour cell (TC) membrane as detected by VENTANA PD-L1 (SP263) Assay in NSCLC may be associated with enhanced survival from OPDIVO® (nivolumab).

Urothelial Carcinoma:

PD-L1 High status as determined by VENTANA PD-L1 (SP263) Assay was associated with increased objective response rate (ORR) in a single arm study of IMFINZI™ (durvalumab). PD-L1 status is determined by the percentage of tumour cells with any membrane staining above background or by the percentage of tumour-associated immune cells with staining (IC+) at any intensity above background. The percent of tumour area occupied by any tumour-associated immune cells (Immune Cells Present, ICP) is used to determine IC+, which is the percent area of ICP exhibiting PD-L1 positive immune cell staining.

A qualified pathologist should interpret this product in conjunction with histological examination, relevant clinical information, and proper controls.

This product is intended for in vitro diagnostic (IVD) use.

The assay is intended for identifying patients who may benefit from therapy, as shown in Table 1. Please refer to the respective drug labelling for clinical recommendations pertaining to PD-L1 expression.
