PRODIGE 98 : Randomized, Multicenter Phase 3 Trial of Adjuvant Chemotherapy With Modified FOLFIRINOX Versus Capecitabine or Gemcitabine in Patients With Resected Ampullary Adenocarcinoma

Обзор

Ampullary adenocarcinoma (AMPAC) is a rare cancer (0.2% of digestive cancers) affecting the ampulla of Vater. The only curative treatment is surgery, but around 4% of patients recur within 2 years of surgical resection. The aim of adjuvant chemotherapy is to reduce the risk of disease recurrence, and the only chemotherapies that can be considered standard to date are capecitabine and gemcitabine. In this trial, an alternative experimental treatment strategy using modified FOLFORINOX (mFOLFORINOX) is proposed. It consists of 3 chemotherapies with complementary actions: 5-fluorouracil, irinotecan and oxaliplatin, combined with folic acid a vitamin that enhances the efficacy of 5-fluorouracil. This study proposes 2 treatment schemes: * Group A: mFOLFIRINOX: oxaliplatin, irinotecan, 5-fluorouracil, with folinic acid, * group B: mono-chemotherapy with capecitabine or gemcitabine.

Вмешательства

• Препарат mFOLFORINOX

• Препарат Capecitabine or gemcitabine
  investigator's choice: * Capecitabine 1250 mg/m² BID, 2 weeks on, 1 week off during 8 cycles (24 weeks) OR * Gemcitabine 1000 mg/m² in 30 min; 3 weeks on, 1 week of, during 6 cycles ((24 weeks)
