Epirubicin, Oxaliplatin, and Capecitabine With or Without Panitumumab for Advanced Esophagogastric Cancer: Dose-Finding Study for the Prospective Multicenter, Randomized, Phase II/III REAL-3 Trial

Epirubicin, Oxaliplatin, and Capecitabine With or Without Panitumumab for Advanced... Purpose: Epirubicin, oxaliplatin, and capecitabine (EOC) is a standard treatment in advanced esophagogastric cancer. Panitumumab (P) is a fully human, immunoglobulin G2 monoclonal antibody targeting epidermal growth factor receptor. Randomized Trial of EOC +/- Panitumumab for Advanced and Locally Advanced Esophagogastric Cancer (REAL-3) will evaluate whether the addition of P to EOC improves survival in patients with advanced esophagogastric adenocarcinoma and undifferentiated carcinoma. Patients and Methods: The original design of REAL-3 added P 9 mg/kg to the standard dose of EOC (dose level [DL] + 1). Due to toxicity, a dose de-escalation was made to EOC + P DL - 1 (epirubicin 50 mg/m2, oxaliplatin130 mg/m2, capecitabine 1,000 mg/m2/d + P 9 mg/kg every 3 weeks). After additional toxicity was observed, the study was amended to include two additional EOC + P dose levels. Using a 3 + 3 design, dose-limiting toxicities (DLTs) were assessed weekly during cycle 1. Patients were randomly assigned 1:1 to EOC +/- P. Results: Between July 2008 and October 2009, 29 patients were randomly selected for standard-dose EOC (n = 13) or EOC + P (n = 16). Five patients were treated at DL + 1, with grade 3 diarrhea in four of five patients by cycle 4. At DL - 1, one patient had grade 3 diarrhea and grade 5 infection. Three patients were treated at DL - 3, and then six were treated at DL - 2, without DLTs. Conclusion: The recommended dose for EOC + P is epirubicin 50 mg/m2, oxaliplatin 100 mg/m2, capecitabine 1,000 mg/m2/d, and P 9 mg/kg every 3 weeks. This dose has been selected for the ongoing phase II/III REAL-3 study. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Clinical Oncology Wolters Kluwer Health

Abstract

Purpose: Epirubicin, oxaliplatin, and capecitabine (EOC) is a standard treatment in advanced esophagogastric cancer. Panitumumab (P) is a fully human, immunoglobulin G2 monoclonal antibody targeting epidermal growth factor receptor. Randomized Trial of EOC +/- Panitumumab for Advanced and Locally Advanced Esophagogastric Cancer (REAL-3) will evaluate whether the addition of P to EOC improves survival in patients with advanced esophagogastric adenocarcinoma and undifferentiated carcinoma. Patients and Methods: The original design of REAL-3 added P 9 mg/kg to the standard dose of EOC (dose level [DL] + 1). Due to toxicity, a dose de-escalation was made to EOC + P DL - 1 (epirubicin 50 mg/m2, oxaliplatin130 mg/m2, capecitabine 1,000 mg/m2/d + P 9 mg/kg every 3 weeks). After additional toxicity was observed, the study was amended to include two additional EOC + P dose levels. Using a 3 + 3 design, dose-limiting toxicities (DLTs) were assessed weekly during cycle 1. Patients were randomly assigned 1:1 to EOC +/- P. Results: Between July 2008 and October 2009, 29 patients were randomly selected for standard-dose EOC (n = 13) or EOC + P (n = 16). Five patients were treated at DL + 1, with grade 3 diarrhea in four of five patients by cycle 4. At DL - 1, one patient had grade 3 diarrhea and grade 5 infection. Three patients were treated at DL - 3, and then six were treated at DL - 2, without DLTs. Conclusion: The recommended dose for EOC + P is epirubicin 50 mg/m2, oxaliplatin 100 mg/m2, capecitabine 1,000 mg/m2/d, and P 9 mg/kg every 3 weeks. This dose has been selected for the ongoing phase II/III REAL-3 study.
