Therapeutic Response Statement (Sensitivity)
This therapeutic response statement supports the relationship that PD-L1 (CPS) >= 10 status confers therapeutic sensitivity to Pembrolizumab in patients with Esophageal Adenocarcinoma.
The U.S. Food and Drug Administration granted approval to pembrolizumab for the treatment of patients with locally advanced or metastatic esophageal or gastroesophageal junction (GEJ) (tumors with epicenter 1 to 5 centimeters above the GEJ) carcinoma that is not amenable to surgical resection or definitive chemoradiation as a single agent after one or more prior lines of systemic therapy for patients with tumors of squamous cell histology that express PD-L1 (CPS >=10), as determined by an FDA-approved test.
This statement is based on a regulatory approval from the Food and Drug Administration:
KEYTRUDA is a programmed death receptor-1 (PD-1)-blocking antibody indicated for the treatment of patients with locally advanced or metastatic esophageal or gastroesophageal junction (GEJ) (tumors with epicenter 1 to 5 centimeters above the GEJ) carcinoma that is not amenable to surgical resection or definitive chemoradiation as a single agent after one or more prior lines of systemic therapy for patients with tumors of squamous cell histology that express PD-L1 (CPS >=10) as determined by an FDA-approved test.
