Dose-dense Biweekly Docetaxel Combined With 5-fluorouracil as First-line Treatment in Advanced Gastric Cancer

A Phase II Trial Evaluating Biweekly Docetaxel and DeGramont Regimen in First-Line Treatment of Unresectable or Metastatic Gastric Adenocarcinoma (DaeMon)

This is an open-label, phase II study to evaluate the efficacy and safety of biweekly docetaxel and DeGramont regimen on unresectable gastric adenocarcinoma in the first-line therapy.

Primary endpoint: Overall Response Rate

Secondary endpoint: Time to progression, overall survival, safety data

• At least 3 weeks since last major surgery
• At least 12 months since last adjuvant chemotherapy
• At least 6 weeks since prior radiotherapy providing that the extent and site of radiotherapy fields are such that marked bone marrow suppression is NOT expected

• A probable life expectancy of at least 6 months;

Exclusion Criteria:
