Approval Order Statement 
Approval for the pd-l1 ihc 28-8 pharmdx. This device is indicated for the following: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) and melanoma tissue using envision flex visualization system on autostainer link 48. Pd-l1 protein expression is defined as the percentage of tumor cells exhibiting positive membrane staining at any intensity. Pd-l1 expression as detected by pd-l1 ihc pharmdx in nonsquamous nsclc may be associated with enhanced survival from opdivo® (nivolumab). Positive pd-l1 status as determined by pd-l1 ihc 28-8 pharmdx in melanoma is correlated with the magnitude of the treatment effect on progression-free survival from opdivo®.
