JS001 Combined With TP as First-line Treatment for Unresectable or Advanced Small Cell Esophageal Carcinoma

Официальное название

JS001 Combined With Nab-paclitaxel and Cisplatin or Carboplatin as First-line Treatment for Unresectable or Advanced Small Cell Esophageal Carcinoma : a Prospective, Single Arm, Multicenter, Phase II Clinical Trial

Обзор

Small cell esophageal carcinoma (SCCE) is a kind of malignant tumor with poor prognosis. Our study found that the mutation spectrum and somatic CNV spectrum of SCCE were similar to those of esophageal squamous cell carcinoma (ESCC). Paclitaxel combined with cisplatin or carboplatin is the first-line treatment for ESCC. JS001 is a Chinese anti-PD-1 monoclonal antibody, which has been approved for the treatment of melanoma. This is a prospective, single arm, multicenter, phase II clinical trial of JS001 combined with nab-paclitaxel and cisplatin or carboplatin in the first-line treatment of unresectable or advanced SCCE. Aim to evaluate the safety and efficacy of this regimen in patients with unresectable or advanced SCCE.

Подробное описание

Small cell esophageal carcinoma (SCCE) is a kind of malignant tumor with poor prognosis. Our previous studies found that the mutation spectrum and somatic CNV spectrum of SCCE were similar to those of esophageal squamous cell carcinoma (ESCC). Paclitaxel combined with cisplatin or carboplatin is a common first-line treatment for ESCC. In addition, some studies have shown that PD-1 mAb combined with paclitaxel chemotherapy in esophageal cancer has better efficacy and tolerability than chemotherapy alone. JS001 is a Chinese monoclonal antibody against PD-1 for injection, which has been approved for the treatment of melanoma. This is a prospective, single arm, multicenter, phase II clinical trial of JS001 combined with nab-paclitaxel and cisplatin or carboplatin in the first-line treatment of unresectable or advanced SCCE. Aim to evaluate the safety and efficacy of this regimen in patients with unresectable or advanced SCCE.
