Combining Sintilimab with Chemotherapy and Radiotherapy for Advanced Esophagogastric Junction Cancer

A Clinical Study of the Efficacy and Safety of Sintilimab in Combination With Chemotherapy (S-1/Oxaliplatin, SOX) and Radiotherapy for the Neoadjuvant Treatment of Locally Advanced Esophagogastric Junction Adenocarcinoma

Phase 2 Interventional Wuhan Union Hospital, China · NCT06250894

This study is testing a new treatment that combines a drug called Sintilimab with chemotherapy and radiation to see if it helps people with advanced esophagogastric junction cancer before surgery.

What this trial studies

This study evaluates the safety and effectiveness of neoadjuvant immunotherapy using Sintilimab, a PD-1 inhibitor, in conjunction with chemotherapy (S-1 and Oxaliplatin) and radiotherapy for patients with locally advanced adenocarcinoma of the esophagogastric junction. Participants will receive this combination treatment before surgical intervention to assess its impact on tumor response. The study aims to improve outcomes for patients with this challenging cancer type by potentially enhancing tumor shrinkage and overall survival rates.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with histologically confirmed locally advanced esophagogastric junction adenocarcinoma who have not received prior anti-tumor treatments.

Not a fit: Patients with known Her-2 positive tumors or those who have previously received immunotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment outcomes and survival rates for patients with locally advanced esophagogastric junction cancer.

How similar studies have performed: While the combination of immunotherapy and chemoradiotherapy is being explored in various cancers, this specific approach for esophagogastric junction adenocarcinoma is relatively novel and has not been extensively tested.
