Roche Receives FDA Approval for Complementary PD-L1 (SP263) Biomarker Test in Urothelial Carcinoma

Roche announced approval of the Ventana PD-L1 (SP263) Assay by the US Food and Drug Administration (FDA) as a complementary diagnostic to provide PD-L1 status for patients with locally advanced or metastatic urothelial carcinoma (mUC) who are being considered for treatment with the FDA-approved anti-PD-L1 immunotherapy Imfinzi.

The test evaluates patient PD-L1 status using both tumor and immune cell staining and scoring within the tumor microenvironment, providing clinicians with information that may guide treatment decisions. PD-L1is a protein involved in the suppression of the immune system, which can impact the body's ability to fight cancer. Understanding the expression of PD-L1 in tumors can help identify patients most likely to benefit from immunotherapy.

It is estimated that in 2017, approximately 79,000 Americans will be diagnosed with bladder cancer and almost 17,000 will die from this disease. Men are three to four times more likely than women to suffer from this cancer.

"Urothelial carcinoma is an area of significant unmet medical need," Ann Costello, Head of Roche Tissue Diagnostics said. "We are very pleased the VENTANA PD-L1 (SP263) Assay has received FDA approval as it will serve as a powerful tool to help inform physicians about appropriate treatment options for their patients."
