Title:
A Study to Evaluate the Efficacy and Safety of Toripalimab Injection in the Treatment of Recurrent or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma Who Have Failed at Least Two Prior Lines of Therapy and Are Positive Specific Markers
Excerpt:
...Previous tumor samples or fresh tumor tissue biopsy samples can be provided, and any of the following biomarkers are confirmed positive by the central laboratory: 1)PD-L1 positive: defined as PD-L1 staining positive at any intensity in ≥5% tumor cells (TC) or ≥10% immune cells (IC); 2)Epstein-Barr virus (EBV) positive: defined as positive for EBV-encoded small RNA in situ hybridization (EBER-ISH); 3)Tumor mutation burden-high (TMB-H): tumor tissues will be detected by whole exome sequencing (WES), with tumor mutation burden ≥12 Muts/Mb; 4)Microsatellite instability-high (MSI-H): Tumor tissue is tested by whole exome sequencing (WES) to confirm MSI-H positivity; 6....
