Agilent Receives FDA Approval for Expanded Use of PD-L1 IHC 22C3 pharmDx on Dako Omnis in Esophageal Squamous Cell Carcinoma, Triple-Negative Breast Cancer, Cervical Cancer, and Gastric or Gastroesophageal Junction Adenocarcinoma
Approval expands PD-L1 testing onto an automated workflow to support treatment decisions with KEYTRUDA® (pembrolizumab)¹,²
Agilent Technologies Inc. (NYSE: A) today announced that the U.S. Food and Drug Administration (FDA) has approved the expanded use of PD-L1 IHC 22C3 pharmDx, Code GE006, for use on the Dako Omnis platform to aid in identifying patients in the United States with esophageal squamous cell carcinoma (ESCC)3, triple-negative breast cancer (TNBC)4, cervical cancer5, and gastric or gastroesophageal junction (GEJ) adenocarcinoma6, who may be eligible for treatment with KEYTRUDA® (pembrolizumab), Merck’s anti-PD-1 therapy.
This approval expands access to PD-L1 testing across four additional tumor types beyond the previously approved non-small cell lung cancer (NSCLC)7 and head and neck squamous cell carcinoma (HNSCC)8. Until now, these FDA-approved PD-L1 IHC 22C3 pharmDx indications have been available on Autostainer Link 48 (ASL48) as the only platform and are now also approved for the Dako Omnis platform. This enables pathology laboratories to consolidate PD-L1 testing across more tumor types within a single automated Dako Omnis workflow, supporting increased automation and operational efficiency.
