Excerpt:S+C showed a significant improvement in OS vs C in pts with CPS≥5...PFS was superior with S+C vs C in pts with CPS≥5...nconfirmed ORR were 72.8% vs 59.6% in pts with CPS≥5 and 65.1% vs 58.7% in all pts with measurable disease, with a median DOR of 8.4 vs 5.5 and 8.6 vs 5.5 months, respectively.

Innovent Announces Sintilimab in Combination with Chemotherapy Meets the Primary Endpoint of Overall Survival in the Phase 3 ORIENT-16 Study for the First-Line Treatment of Advanced or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma
Excerpt:Innovent Biologics, Inc....today announced that the sintilimab Phase 3 ORIENT-16 study met its predefined primary endpoint of overall survival (OS)....In an interim analysis, sintilimab in combination with chemotherapy demonstrated a statistically significant improvement in the primary endpoint of OS compared to placebo plus chemotherapy, in both the intention-to-treat (ITT) group and PD-L1 positive group.

Title:
784 Biomarkers of perioperative immunotherapy in combination with concurrent chemoradiotherapy for locally advanced gastric or gastroesophageal junction adenocarcinoma
Excerpt:34 patients with locally advanced G/GEJ cancer received anti-PD-1 therapy (Sintilimab)...Our results met the pre-specified primary endpoint, with a pCR rate of 38.2% and median DFS of 17.0 months. Tumor mutation burden (TMB) analyzed by NGS was significantly higher in the pCR group than those not achieving pCR (non-pCR)...Biomarker analysis by mIF showed patients with positive PD-L1 expression showed a numerically higher pCR rate...positive PD-L1 expression, higher T cell infiltration and TMB could be predictive biomarkers of perioperative anti-PD-1 therapy in combination with cCRT for locally advanced G/GEJ.
