Useful For
PD-L1 IHC 28-8 pharmDx is a qualitative immunohistochemical assay using Monoclonal Rabbit Anti-PD-L1, clone 28-8 intended for use in the detection of PD-L1 protein in formalin-fixed, paraffin-embedded (FFPE) non-squamous non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (SCCHN), and urothelial carcinoma tissues using EnVision FLEX visualization system on Autostainer Link 48. FDA approved for lung cancer (CHECKMATE 057 Clinical Trial).

Test Information
Testing is not required for use of OPDIVO in NSCLC, head and neck squamous cell carcinoma, or urothelial carcinoma, but may provide physicians more information and inform patient dialogue. In non-squamous NSCLC, PD-L1 expression as detected by PD-L1 IHC 28-8 pharmDx may be associated with enhanced survival from OPDIVO.
