Phase II Study of Fruquintinib Plus SOX as Neoadjuvant Therapy for Locally Advanced Gastric Adenocarcinoma

• Status: Recruiting
• Trial end date: 2024-11-30
• Target enrollment: 0
• Participant gender: All

Summary

For locally advanced gastric/gastroesophageal junction adenocarcinoma (cT3/4aN+M0 ), neoadjuvant therapy can downstage T and N stage, improve R0 resection rate, reduce recurrence and metastasis rates, and finally improve the long-term survival. A combination of Fruquintinib and SOX for locally advanced gastric/gastroesophageal junction adenocarcinoma could be a novel therapy. This study intends to evaluate the efficacy of Fruquintinib plus SOX as neoadjuvant therapy for locally advanced gastric or gastroesophageal junction adenocarcinoma.

• Phase: Phase 2
