Summary

This study investigates the efficacy and safety of XELOX chemotherapy combined with sintilimab and hyperbaric oxygen therapy (HBOT) as a first-line treatment for patients with Advanced or Metastatic gastric and gastroesophageal junction adenocarcinoma. The trial comprises two phases: a phase Ib study to determine the optimal HBOT regimen and assess safety and tolerability, followed by a phase II study to evaluate the overall response rate (ORR). Secondary outcomes include progression-free survival (PFS), disease control rate (DCR), 2-year disease-free survival (DFS), 2-year overall survival (OS), safety, and quality of life. This study aims to provide a novel approach for enhancing therapeutic efficacy and improving patient outcomes by leveraging HBOT to address tumor hypoxia and augment the effects of chemotherapy and immune checkpoint inhibitors.

  • Gastric (Stomach) Cancer

Interventions

DRUG

XELOX+Sintilimab+HBOT

Patients will receive the XELOX regimen, consisting of oxaliplatin (130 mg/m² IV on Day 1) and capecitabine (1000 mg/m² orally twice daily for 14 days, repeated every 3 weeks), combined with sintilimab (200 mg IV on Day 1 every 3 weeks) and hyperbaric oxygen therapy (HBOT) administered alongside the XELOX regimen. Treatment will be administered for 4 to 6 cycles. Following the initial treatment phase, patients will be evaluated for response. If disease progression is observed, patients will exit the study and receive subsequent treatments as deemed appropriate. For patients with stable disease or a response to therapy, maintenance treatment with capecitabine and sintilimab will continue until the occurrence of a study endpoint or other specified criteria.
