A Trial Assessing Several Schedules of Oral S-1 in Combination With a Fixed Dose of Oxaliplatin and Irinotecan (SIRINOX)

A Phase I Trial Assessing Several Schedules of Oral S-1 in Combination With a Fixed Dose of Oxaliplatin and Irinotecan in Patients With Advanced or Metastatic Digestive Adenocarcinoma as First- or Second-line Treatment

This study is to determine the Maximal Tolerated Dose (MTD), the Dose Limitant Toxicities (DLTs) and the safety profile of S-1 combined with fixed doses of Irinotecan (SIRI schedule) and fixed doses of Irinotecan and Oxaliplatin (SIRINOX schedule).

Study Overview

• Status: Completed
• Conditions: Digestive Cancer
• Intervention / Treatment: Drug: S-1; Drug: Irinotecan; Drug: Oxaliplatin; Other: G-csf

Detailed Description

Given the therapeutic potential and reduced toxicity advantages of S-1 compared with other fluoropyrimidines, this trial assessing S-1 with Oxaliplatin plus Irinotecan is warranted for future investigations (Phase II-III). The primary objectives are to determine the Maximal Tolerated Dose (MTD), the Dose Limitant Toxicities (DLTs) and the safety profile of S-1 combined with fixed doses of Irinotecan (SIRI schedule) and fixed doses of Irinotecan and Oxaliplatin (SIRINOX schedule).

Participant Group / Arm

Intervention / Treatment

Experimental: SIRINOX; S-1: Administered orally twice daily from day 1 for 7 consecutive days followed by a 7-day recovery period in a 14-day cycle. The starting dose of S-1 will be two levels below the recommended dose defined in SIRI (20 mg/m² BID minimum) with a cohort dose escalation by 5 mg/m² increments (5 dose levels). Irinotecan : fixed dose of 180 mg/m² IV over 90 minutes on d1 of every cycle Oxaliplatin : fixed dose of 85 mg/m² over 120 minutes on d1 of every cycle G-csf : d8 to d13 systematically
