Randomized phase III trial of post-operative chemotherapy for patients with stage I/II/III small bowel adenocarcinoma (JCOG1502C, J-BALLAD)

Abstract

A randomized phase III trial was initiated in May 2017 to confirm the superiority of post-operative therapy with capecitabine and oxaliplatin over observation in terms of relapse-free survival in patients with curatively resected small bowel adenocarcinoma. Total 150 patients will be enrolled from 20 Japanese institutions over a period of 6.5 years. Relapse-free survival is the primary endpoint, while the secondary endpoints are overall survival, disease-free survival as defined by the Japan Clinical Oncology Group (JCOG), disease-free survival as defined by the International Rare Cancer Initiative (IRCI), and adverse events. Global phase III trial of IRCI to confirm the superiority of post-operative chemotherapy for small bowel adenocarcinoma was started in the UK in August 2015 (ClinicalTrials.gov Identifier: NCT02502370). An integrated analysis of the IRCI trial and our study are planned. Our trial has been registered in the UMIN Clinical Trials Registry as UMIN000027280 (http://www.umin.ac.jp/ctr/index.htm).
