Safety and Efficacy of Combination of Sintilimab and Platinum-based Chemotherapy in Neoadjuvant Treatment of Potentially Resectable Esophageal Cancer: An Open-lable, Single-arm, Exploratory Clinical Study
Safety and Efficacy of Combination of Sintilimab and Platinum-based Chemotherapy in Neoadjuvant Treatment of Potentially Resectable Esophageal Cancer: An Open-lable, Single-arm, Exploratory Clinical Study
This study aims to investigate the safety and efficacy of sintilimab combined with platinum-based chemotherapy in neoadjuvant treatment of potentially resectable esophageal cancer.
This study was designed as an open-lable, single-arm, exploratory clinical study. Sintilimab in combination with liposomal paclitaxel, cisplatin and S-1 will be given every 3 weeks to our patients for 2 cycles as neoadjuvant therapy. A radical dissection is scheduled within 6 weeks after last neoadjuvant treatment. This study will be devided for 3 phases: safety run-in, efficacy pilot and efficacy confirmation.
Inclusion Criteria:
Histologically or cytologically confirmed esophageal squamous cell carcinoma.
The tumor is located in the middle or lower third of the esophagus ( more than 18cm below incisor), potentially resectable and requiring neoadjuvant therapy (T1b-3, Nany, M0 or T4a, N0-1, M0).
No prior treatment for this disease.
Eastern cooperative oncology group (ECOG) performance status of 0 to 1.
Adequate bone marrow, liver, cardiac and renal function as assessed by the laboratory required by protocol.
Understand and voluntarily sign the informed consent(s).
Patients who are able to complete the treatment and follow-up according to the study plan.
Patients who have sufficient tissue samples and agree to provide their tissue samples and blood samples for detailed analysis.
