PD‑L1 28‑8 FDA for NSCLC
Also known as: Formerly named PD-L1 28-8 FDA (OPDIVO® + YERVOY®) for NSCLC
Use
PD‑L1 IHC 28‑8 pharmDx is a qualitative immunohistochemical assay using Monoclonal Rabbit Anti‑PD‑L1, clone 28‑8, intended for detection of PD‑L1 protein in FFPE non‑small cell lung cancer tissue. It serves as an aid in identifying NSCLC patients for treatment with OPDIVO® (nivolumab) or OPDIVO in combination with YERVOY® (ipilimumab). Results are positive when PD‑L1 is expressed in ≥1% of tumor cells, supporting treatment decisions. Stain‑only (tech‑only) testing is available for clients with completed interpretation training.
