May 6, 2019 updated by: Dazhi Xu, Fudan University

A Prospective,Multicentral,Open-label,Randomized,Controlled,Phase III Clinical Trial to Compare S-1 for 6 Months to 1 Year as Adjuvant Chemotherapy After D2 Resection in Patients With Gastric Cancer Staged II , IIIA or IIIB.

The study aims to compare the efficacy and safety of S-1 for 6 months versus S-1 for 1 year as adjuvant chemotherapy after D2 resection in patients with gastric cancer.

Hypothesis: For gastric patients after D2 resection, S-1 for 6 months shows non-inferiority to S-1 for 1 year in disease free survival(DFS), overall survival (OS) and safety.

Detailed Description

It has been identified that S-1 is an effective adjuvant treatment for East Asian patients who have undergone a D2 dissection for locally advanced gastric cancer（GC) in the Japanese Adjuvant Chemotherapy Trial of TS-1（S-1) for Gastric Cancer (ACTS-GC) trail , And S-1 has become one of the standard therapies to these patients. But it is still unknown whether it would improve equally or even more to overall survival(OS) and disease free survival(DFS) than S-1 for 1 year compared with S-1 for 6 months. As a result , An further clinical trail is still needed, This trial is designed to investigate the efficacy and safety of S-1 for 6 months versus S-1 for 1 year as adjuvant chemotherapy after D2 resection in patients with gastric cancer.

In this study, patients histologically confirmed stage II, IIIA or IIIB and who received D2 resection were randomly assigned to receive S-1 for 6 months or S-1 for 1 year. Patients aged from 18 to 75 years and adequate organ function, are randomized 1:1 to S-1 for 6 months and S-1 for 1 year. Both are the 3-week recycle of S-1 (80-120mg per day) for 2 weeks ,followed by 1 week of rest. The primary end point is 3-year DFS, and secondary end point is 5-year OS and safety. Final study analysis will be conducted in the end of the 5th year after the last patient's enrollment.In summary, we hold the hypothesis that S-1 for 6 months is equally effective, safer, and easier to carry out. If possible, there will be a new adjuvant chemotherapy strategy for gastric cancer patients after D2 resection.

To ensure the quality of the study, two interim analyses will be planned at the half and the completion of the study respectively. The DATA and Safety Monitoring Committee will independently review the interim analysis and stop the study ahead of schedule if necessary. Furthermore, to improve the study progress and quality, the in-house interim monitoring will be performed.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
