Brief Summary: This Phase II clinical study is a prospective open-label single-arm trial designed to evaluate the efficacy and safety of combining anti-PD-1 therapy sintilimab with thymosin α1 and the SOX chemotherapy regimen as a neoadjuvant treatment for patients with clinical stage III gastric or esophagogastric junction GEJ adenocarcinoma The primary objective is to explore the therapeutic efficacy and safety of this combined treatment approach The secondary objective is to assess its impact on the tumor immune microenvironment in locally advanced gastric cancer

Study Design

The study plans to enroll 30 patients who have been pathologically confirmed as HER2-negative and diagnosed with resectable stage III gastric or GEJ adenocarcinoma Siewert type III and type II without the need for thoracotomy The study includes multiple steps

Treatment Regimen Participants will receive three cycles of sintilimab combined with the SOX regimen oxaliplatin and S-1 and nine weeks of thymosin α1 before surgery

Assessment Points Tumor response will be evaluated through imaging studies at the end of the second and third cycles of neoadjuvant therapy Post-treatment surgery is scheduled within 2-6 weeks following the last dose of the third cycle

Pathological Evaluation Surgical tumor samples will undergo pathological examination including assessments for pathological complete response pCR tumor regression grade TRG major pathological response MPR overall response rate ORR disease control rate DCR clinical downstaging rate and R0 resection rate

Safety Monitoring Adverse events will be monitored throughout the treatment period to evaluate the safety of the neoadjuvant immunochemotherapy regimen

Follow-up Patients will be followed up to calculate disease-free survival DFS and overall survival OS

Eligibility Criteria

Inclusion Criteria

i Confirmed diagnosis of HER2-negative gastric or GEJ adenocarcinoma ii Clinical stage III resectable tumors iii Adequate organ function and performance status

Exclusion Criteria

i Prior treatment with immune checkpoint inhibitors ii History of autoimmune diseases or other malignancies iii Severe comorbidities that could interfere with the study

Goals and Objectives Primary Goal To determine the effectiveness and safety of combining sintilimab with thymosin α1 and SOX as a neoadjuvant therapy

Secondary Goal To investigate changes in the tumor immune microenvironment induced by the treatment and their correlation with therapeutic efficacy

Study Implications This study aims to provide critical insights into the potential benefits of integrating immunotherapy with chemotherapy and thymosin α1 in treating locally advanced gastric cancer By focusing on both efficacy and immune microenvironment alterations the findings could pave the way for novel neoadjuvant treatment strategies and improve clinical outcomes for gastric cancer patients
