Phase 3 Study of Xelox Followed by Maintenance Capecitabine in the Advanced Gastric Cancer

• Status: Unknown status
• Trial end date: 2019-01-01
• Target enrollment: 0
• Participant gender: All

Summary

XELOX regimen had a more favorable toxicity profile compared to cisplatin for patients with advanced gastric cancer. The safety profile of oxaliplatin makes it an ideal candidate for combination therapy. However, oxaliplatin induce sensory neuropathy, a cumulative, dose-related toxicity. It may therefore be possible to devise capecitabine maintenance regimen which achieves maximum treatment effect before cumulative neurotoxicity appears. We study that randomized Phase III study of Xelox (Capecitabine plus Oxaliplatin) followed by maintenance Capecitabine or Observation in the gastric cancer patients of stable disease after 6 cycle 1st line of XELOX chemotherapy .

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details
