Study of Larotinib in Unresectable Advanced or Recurrent Esophageal Cancer

This is a randomized, controlled, multi-center, open trial, unresectable locally advanced or metastatic esophageal squamous cell carcinoma patients that failed at least second-line treatment and overexpressed EGFR were enrolled and randomly assigned to the experimental group and control group at a 1: 1 ratio.,who received Larotinib and the chemotherapy regimen chosen by the investigator (Irinotecan Hydrochloride Injection or Tegafur Gimeracil Oteracil Potassium Capsule),respecitively. Subjects are administered until disease progression assessed by the RECIST V1.1 standard (unless the investigator evaluates that the subject continues to have clinical benefit from continuing treatment, the subject may be allowed to continue treatment), and begins to receive new anti-tumor treatment, unacceptable toxicity, withdrawal of informed consent, or other conditions that meet the criteria for terminating trial treatment / withdrawal from the trial. The research phase of this study is divided into pre-screening period (\~ D-28), screening period (D-28 \~ D-1), treatment period, treatment end visit (± 7 days after the last dose), safety follow-up ( Until 28 ± 7 days after the last dose) and survival follow-up.
