Agilent Technologies (NYSE:A) today announced that the U.S. Food and Drug Administration (FDA) has approved its Dako PD-L1 IHC 22C3 pharmDx assay for expanded use in urothelial carcinoma.

As quoted in the press release:

The assay is now approved to identify patients with urothelial carcinoma who may benefit from KEYTRUDA, an anti-PD-1 therapy manufactured by Merck (known as MSD outside the United States and Canada), as a first-line treatment option. KEYTRUDA is approved for patients with locally advanced or metastatic urothelial carcinoma who are not eligible for cisplatin-containing chemotherapy and whose tumors express PD-L1 [Combined Positive Score (CPS) ≥ 10] as determined by an FDA-approved test, or in patients who are not eligible for any platinum-containing chemotherapy regardless of PD-L1 status.
PD-L1 IHC 22C3 pharmDx is the only FDA-approved companion diagnostic to identify patients with urothelial carcinoma for treatment with KEYTRUDA. This follows previous FDA approvals for PD-L1 IHC 22C3 pharmDx in non-small cell lung cancer (NSCLC), gastric or gastroesophageal junction (GEJ) adenocarcinoma, and cervical cancer.
