Combination treatment for advanced esophageal and gastric cancers

Tucidinostat in Combination With PD-1 Inhibitor and Bevacizumab as Late-line Treatment in Patients With Advanced Esophageal Squamous Cell Cancer, Adenocarcinoma of Esophagogastric Junction and Gastric Adenocarcinoma

Phase 2 Interventional Sun Yat-sen University · NCT05163483

This study is testing a new combination treatment for people with advanced esophageal and gastric cancers to see if it can help them when their cancer can't be removed or has come back.

What this trial studies

This Phase II study evaluates the safety and efficacy of a combination therapy involving Tucidinostat, a histone deacetylase inhibitor, along with a PD-1 inhibitor and Bevacizumab in patients with advanced esophageal squamous cell cancer, adenocarcinoma of the esophagogastric junction, and gastric adenocarcinoma. The study aims to determine how well this combination works in patients whose cancer is unresectable, recurrent, or metastatic. Participants must provide tumor tissue samples and meet specific health criteria to be eligible for the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with confirmed advanced esophageal or gastric cancers who have limited prior treatments.

Not a fit: Patients with early-stage cancer or those who have received extensive prior treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced esophageal and gastric cancers.

How similar studies have performed: Other studies have shown promise with similar combination therapies in treating advanced cancers, suggesting potential for success in this approach.
