PD-L1 SP263 FDA for NSCLC
Use
The VENTANA PD‑L1 (SP263) assay is a qualitative immunohistochemical test using rabbit monoclonal anti‑PD‑L1 clone SP263 for formalin‑fixed, paraffin‑embedded (FFPE) non‑small cell lung cancer (NSCLC) tissue. It aids in assessing PD‑L1 expression to help identify NSCLC patients eligible for treatment with TECENTRIQ® (atezolizumab) when tumor cell PD‑L1 expression is ≥1%, and for LIBTAYO® (cemiplimab‑rwlc) when PD‑L1 expression is ≥50% on tumor cells at any intensity.
