Esophagogastric Junction Adenocarcinoma

The purpose of this clinical trial is to evaluate whether perioperative fruquintinib combined with sintilimab and SOX is effective in treating locally advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma. The study will also assess the safety profile of this treatment regimen. Primary Objective: To determine whether perioperative fruquintinib combined with sintilimab and SOX improves the pathological complete response (pCR) rate compared with sintilimab plus SOX in patients with locally advanced gastric or GEJ adenocarcinoma. Study Design: Participants will be randomly assigned to receive either fruquintinib combined with sintilimab and SOX or sintilimab plus SOX to evaluate the potential added benefit of fruquintinib in this setting. Participation Details: Participants will receive the assigned treatment (fruquintinib combined with sintilimab and SOX or sintilimab plus SOX) every 21 days for approximately 3 months. They will visit the clinic once every 3 weeks for evaluations, laboratory tests, and monitoring. Participants will be asked to keep a daily diary to record any symptoms or side effects experienced during the study.

This study is a prospective, single-arm, phase II clinical study. Screening patients with stage III GC/GEJ adenocarcinoma after D2 or broader radical resection. After enrolling in the study, the subjects receive Sintilimab combined with oxaliplatin+Tegafur, Gimeracil and Oteracil Potassium Capsules (SOX) or oxaliplatin+Capecitabine (XELOX) , in which the combined chemotherapy is up to 8 cycles, and the total course of treatment was 16 cycles. The following-up of subjects includes adverse events、disease status、living conditions and the quality of life.

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 (Serplulimab) with thymalfasin and the SOX chemotherapy regimen as a neoadjuvant treatment for patients with clinical stage III gastric or gastroesophageal junction(GEJ) adenocarcinoma.

With this trial, we aim to evaluate a new combination therapy with tislelizumab and FLOT chemotherapy before surgery (neoadjuvant) for locally advanced, resectable adenocarcinoma of the esophagus or stomach (EGA). The aim of this phase Ib trial is to determine whether this combination is safe and clinically active enough to support the continuation of this concept in subsequent trials investigating novel drug combinations in the neoadjuvant setting of locally advanced EGA. As many patients are unable to tolerate the postoperative part of the standard therapy concept, we aim here to assess a prolongation of preoperative therapy to 6 or 8 applications of FLOT, instead of the routinely administered 4 pre- and 4 postoperative applications, in combination with tislelizumab.

The purpose of this study is to access the safety and efficacy of neoadjuvant Immunotherapy (Sintilimab, PD-1 inhibitor) combined with chemotherapy (Tegafur+Oxaliplatin) for locally advanced esophagogastric junction adenocarcinoma.

The purpose of this study is to explore the effectiveness and safety of immunotherapy (Adebrelimab, a PD-L1 inhibitor) combined with standard chemotherapy (XELOX) in the perioperative treatment of resectable esophagogastric junction adenocarcinoma.
