Nivolumab for the Treatment of Esophageal Squamous Cell Carcinoma
Abstract:
Overview
Esophageal cancer is the seventh most common malignancy, for which there are few effective treatment options, especially for patients with advanced disease. Therefore, the therapeutic development of immune checkpoint inhibitors has been the focus for patients with advanced esophageal cancer. Nivolumab, a human monoclonal immunoglobulin G4 antibody that inhibits programmed cell death protein 1, has been developed for this patient population. The phase II ATTRACTION-1 trial showed promising efficacy for nivolumab in patients with advanced esophageal cancer who were refractory or intolerant to fluoropyrimidine-, platinum-, and taxane-based chemotherapies. The phase III ATTRACTION-3 trial showed the superiority of nivolumab over taxane in patients with advanced esophageal squamous cell carcinoma (ESCC) who were refractory or intolerant to previous fluoropyrimidine- and platinum-based chemotherapy. Based on these results, the FDA approved nivolumab as a treatment for patients with advanced ESCC after prior fluoropyrimidine- and platinum-based chemotherapy. Additionally, the CheckMate 577 trial has shown that nivolumab improves disease-free survival when used as an adjuvant treatment in patients with resectable tumors who received neoadjuvant chemoradiation followed by surgery, and in whom a pathological complete response was not achieved. Clinical trials to evaluate the efficacy of nivolumab in combination with cytotoxic drugs as first-line chemotherapy, in combination with chemoradiotherapy, or for the treatment of perioperative patients with esophageal cancer are ongoing and might contribute to the establishment of new standard treatments.
